Scheduled Maintenance

[Standard] Tron - Mainnet and Nile Testnet - Upgrade to v4.8.2.2 Sep 28, 2026 00:00-06:00 UTC

We are upgrading our Tron Mainnet infrastructure to v4.8.2.2 and our Tron Nile Testnet infrastructure to v4.8.2.2-PQ1-build1. This is a mandatory upgrade issued by the Tron Foundation, applying to both mainnet and Nile testnet.

During the maintenance window, brief interruptions to RPC availability may occur.

RPC Changes:
- Contract deployment transactions now go through refined validation, improving consistency and reliability for users deploying smart contracts. Stake 2.0 and SELFDESTRUCT instruction handling has been optimized for edge cases, improving consistency of contract execution results for affected calls.

Mainnet release: https://github.com/tronprotocol/java-tron/releases/tag/GreatVoyage-v4.8.2.2 Nile Testnet release: https://github.com/tron-nile-testnet/nile-testnet/releases/tag/GreatVoyage-Nile-v4.8.2.2-PQ1-build1

[Urgent] XRP Ledger - Mainnet - Upgrade to xrpld 3.4.0 Sep 28, 2026 00:00 - Sep 29, 2026 00:00 UTC

We are upgrading our XRP Ledger Mainnet infrastructure to xrpld 3.4.0 on 2026-09-28. This is a major release introducing two new amendments—LendingProtocolV1_1 (extending Single Asset Vaults and the Lending Protocol with closed-ended vaults and cash-basis accounting) and fixCleanup3_4_0 (bundling protocol fixes)—while retiring the fixAMMOverflowOffer amendment as a permanent part of the protocol. The release also includes bug fixes, security hardening, and stability improvements. Brief interruptions to RPC availability may occur on that date.

RPC Changes:
ledger — Added nftoken_id, nftoken_offer_id, and delivered_amount (for AccountDelete transactions) to transaction metadata in ledger RPC responses, matching tx and account_tx methods.
NFT buy/sell flag validation — NFT RPC input now validates the buy/sell flag and will reject invalid flag combinations.

Scheduled — Solana Mainnet client upgrade (Agave v4.3.0) Sep 29, 2026 00:00 - Oct 4, 2026 00:00 UTC

Starting 2026-09-29 (UTC), we are upgrading our Solana Mainnet fleet to Agave v4.3.0, the release Anza recommends for Mainnet-beta, together with the matching Yellowstone gRPC (v16) and Blazar builds. RPC, WebSocket and gRPC endpoints stay available throughout. Our staked validators are already on v4.3.0.

What changes for Mainnet clients:

- getBlock, getTransaction and blockSubscribe now reject requests that combine encoding: "base58" (or "binary") with maxSupportedTransactionVersion >= 1, returning JSON-RPC error -32602 "base58 encoding is not supported with maxSupportedTransactionVersion>= 1". Use json, jsonParsed or base64 encoding for Transaction V1 requests.

- getInflationReward now accepts at most 32 addresses per request; larger lists return JSON-RPC error -32602 "Too many inputs provided; max 32". Split larger requests into batches of 32.

- Yellowstone gRPC moves to the v16 line. Existing subscriptions keep working unchanged, including clients built from the v15 proto. The v16 additions (a bank_id field on updates, a block_footer subscription) are optional and inert on Mainnet until Alpenglow activates; regenerate your app from the v16 proto only if you want them.

No JSON-RPC method is added or removed.

Please reach out to our Support team if you are experiencing any issues during the maintenance window.

[Urgent] Mantle Mainnet - Upgrade op-geth to v1.6.3 Sep 29, 2026 00:00 - Sep 30, 2026 00:00 UTC

We are upgrading our Mantle Mainnet infrastructure to op-geth v1.6.3 on 2026-09-29. This release introduces the Elysium execution client, providing compatibility with Ethereum L1 Glamsterdam through the Amsterdam execution framework. The upgrade includes upstream go-ethereum v1.17.3 with EIP-7708 ETH transfer logs, EIP-7928 block access lists, and related Engine and networking changes. Brief interruptions to RPC availability may occur on that date.

RPC Changes:
- eth_simulateV1 — Now supports Mantle fee calculation and returns eth_config safely for blobless OP Stack configurations and Amsterdam forks.
Block headers — The canonical JSON key blockAccessListHash is now used for EIP-7928 block access list references.
- Deposit encoding — Failed BVM_ETH deposit transactions are now represented with correct JSON encoding in receipts and block data.

Urgent XRPL EVM Mainnet - Upgrade to v10.2.1 Sep 30, 2026 00:00 - Oct 1, 2026 00:00 UTC

We are upgrading our XRPL EVM Mainnet infrastructure to node v10.2.1 on 2026-09-30. This is a hotfix release that updates the underlying cosmos/evm module to v0.6.2-august-2026-hotfix-xrplevm.2, addressing core EVM functionality improvements.

Brief interruptions to RPC availability may occur on that date.

[Standard] Stacks - Upgrade API to v9.3.1 & Core 4.0.4 Sep 30, 2026 00:00 - Oct 1, 2026 00:00 UTC

We are upgrading our Stacks infrastructure to Stacks API v9.3.1 and stacks-core 4.0.4 on 2026-09-30. The API release includes a small database migration. The stacks-core release delivers bug fixes and stability improvements for more consistent block production, and introduces Clarity 7 ahead of Epoch 4.1. Brief interruptions to RPC availability may occur during the maintenance.

RPC Changes:

Stacks API (v9.3.1)
- v3 fungible token balances — fixed. Results are now sorted by numeric balance value.

Stacks Core (4.0.4)
- Error messages — changed. vm_error in transaction receipts, the cause field in read-only call responses, and block rejection reasons are now capped at 4096 bytes. Tuple and list values in these messages now render in Clarity syntax (e.g. (tuple (a u1))) instead of internal debug format. Users parsing these strings should update their handling.
- Smart contract deploys (from Epoch 4.1) — breaking. VersionedSmartContract payloads will be rejected as invalid. Deploy using the unversioned SmartContract payload, which defaults to Clarity 7.
- replace-at? (from Epoch 4.1) — fixed. A zero-length buffer or string element is now rejected at type-check time, or fails with an includable error at runtime, rather than making the transaction rejectable.

[Standard, Fork] Ethereum - Sepolia - Upgrade to Geth-v1.17.6 Sep 30, 2026 00:00 - Oct 1, 2026 00:00 UTC

We are upgrading our Ethereum Sepolia infrastructure to Geth v1.17.6 on 2026-09-30. This maintenance release delivers performance improvements to block processing and initial sync, and includes critical preparation for the Amsterdam hard fork scheduled on Sepolia for October 6, 2026.

Brief interruptions to RPC availability may occur.

RPC Changes:
- eth_getLogs — Now rejects ranges where toBlock is before fromBlock; requests with invalid block ranges will return an error.
- eth_getHeaderByNumber — Returns null for pending and unresolvable tags instead of attempting resolution.
- eth_simulateV1 — Post-merge difficulty overrides are now treated as no-op; difficulty parameters no longer affect simulation outcomes.
- eth_createAccessList — Removed per-authorization gas guard; gas accounting behavior has been simplified.
- debug_traceCall — Block parameter is now optional; omitting it will use the latest block by default.

[Standard] Zcash Mainnet - Upgrade to Zebra 6.4.0 Oct 1, 2026 00:00 - Oct 2, 2026 00:00 UTC

We are upgrading our Zcash Mainnet infrastructure to Zebra 6.4.0 on 2026-10-01. This release improves block template performance through precomputation, and includes multiple security and stability fixes.

Brief interruptions to RPC availability may occur on that date.

RPC Changes:
- getblocktemplate — Now uses precomputed block templates for the current chain tip when available, refreshed on tip changes and periodically, reducing latency for miners; templates may be a few seconds behind the mempool but are validated against the committed tip.
- getstandardfee — Reports updated conventional fee of 1000 zatoshis per ZIP-317 logical action (down from 5000; 2000 instead of 10000 for a minimal transaction).
- z_gettreestate — No longer returns null commitments for blocks moved to a side chain during concurrent reorgs.
- RPC response body size — `rpc.max_response_body_size` is now capped at 4,294,967,295 bytes; larger configured values are rejected during configuration loading.

[Standard] Ethereum Hoodi and Sepolia - Upgrade to Reth v2.6.0 Oct 1, 2026 00:00 - Oct 2, 2026 00:00 UTC

We are upgrading our Ethereum Hoodi and Sepolia infrastructure to Reth v2.6.0 on 2026-10-01. This release expands Amsterdam and Bogotá protocol support, advances snap-sync infrastructure, and delivers significant performance improvements across block processing and historical-state RPC queries. Brief interruptions to RPC availability may occur on that date.

RPC Changes:
- eth_getLogs — Returns an error when matching receipts have been pruned instead of incomplete results. Additionally, memory and CPU overhead have been reduced through windowing and bloom-filtering optimizations.
- eth_estimateGas — Basic-transfer shortcut now returns actual used gas, fixing post-Amsterdam overestimation of up to 75%.
- eth_callBundle — Now derives the next-block base fee for bundle simulation.
- Transaction submission and signing — Rejects a caller-supplied chainId that does not match the node, preventing accidental cross-chain resubmission.
- EIP-7702 authorization — Returns null for sender-nonce gaps consumed by authorization entries.
- Transaction pool — Pending blob transactions are now parked when blob fee rises while base fee falls. Configured minimum priority fee is enforced for local transactions, and transactions below tracked sender nonce are rejected when enabled.

[Standard] 0g - Mainnet - Upgrade to v1.0.7 Oct 1, 2026 00:00 - Oct 2, 2026 00:00 UTC

We are upgrading our 0g Mainnet infrastructure to Aristotle v1.0.7 on 2026-10-01. This is an RPC-only release that fixes a critical correctness bug in eth_estimateGas and removes a CPU-amplification vector in the gas estimator. No consensus or state-transition changes are included. Brief interruptions to RPC availability may occur on that date.

RPC Changes:
- eth_estimateGas — Fixed critical bug where gas estimates were being seeded from post-settlement gas (raising gas_used to 80% of the cap), causing the method to return cap-sized limits instead of actual usage. This resulted in gas estimates up to ~850× too large. Estimates are now seeded from pre-settlement gas, matching 0g-geth behavior. Additionally, EIP-7623 calldata floor computation has been optimized to run once per transaction instead of per frame, eliminating a CPU-amplification vector.

Solana Testnet: Alpenglow consensus upgrade on Thursday, Sep 24
Completed - The scheduled maintenance has been completed.
Sep 24, 18:00 UTC
In progress - Scheduled maintenance is currently in progress. We will provide updates as necessary.
Sep 24, 16:00 UTC
Scheduled - The Solana Testnet is switching to Alpenglow, Solana's new consensus protocol (SIMD-0326). The Solana developers at Anza will turn it on at the start of Testnet epoch 1042, expected Thursday, September 24, around 17:30 UTC. The switch-over takes about 5,000 slots, which is roughly 15 to 20 minutes at Testnet's current speed.

Feature gate: A1pengvuM6JEcyNuTnMqepBKhwHE3N6PmUrdATGawhJS (Testnet)


What this means for you
- Solana Mainnet is not affected. This change applies to Solana Testnet only.
- The Testnet may be briefly unstable while the switch-over happens, for example with slower confirmations or short interruptions. This comes from the network itself.
- Your Quicknode Testnet endpoints stay the same. You don’t need to change anything.

What we’re doing
- Our Solana Testnet infrastructure is already running the required Agave v4.3.0.
- We’re pausing all planned maintenance on Solana Testnet around the upgrade window.
- Our team will be actively monitoring the network during and after the switch-over, and we’ll post updates here if we see any impact.

Try Alpenglow early:

Want to see how your application behaves under Alpenglow before it reaches Testnet? It’s already live on our Solana Alpenglow cluster: Spin up a reliable Solana Alpenglow node on Quicknode.

[Urgent] Sui - Mainnet - Upgrade to mainnet-v1.80.1
Completed - The scheduled maintenance has been completed.
Sep 24, 13:47 UTC
Scheduled - We are upgrading our Sui Mainnet infrastructure to mainnet-v1.80.1 on 2026-09-30. This release introduces Protocol Version 137 with improvements to cryptographic verification, new gas charging semantics, and expanded transaction validation. Brief interruptions to RPC availability may occur on that date.

RPC Changes:
SuiTransactionBlockEffects.shared_objects — The field is now derived from accessed consensus objects, which can include implicitly read system objects (such as the accumulator root). Consumers treating this field as declared shared inputs should filter against the transaction inputs to avoid processing unexpected system objects.
Transaction expiration — TransactionExpiration::Validity is now accepted on all networks, allowing transactions to restrict which validators may propose them in consensus.
MovePackageService (gRPC) — GetPackage, GetDatatype, GetFunction, and ListPackageVersions are now available on the Bigtable-backed archival gRPC service (sui-kv-rpc), previously only on fullnodes.
Historical subscription backfill (GraphQL) — Can now consume V1 effects from archival KV-RPC for broader historical data access.
QueryEndReason behavior (gRPC) — Terminal metadata on queries ending at an empty natural interval now emits QueryEndReason::CheckpointBound with watermark.checkpoint = None instead of CursorBoun.

Completed - The scheduled maintenance has been completed.
Sep 24, 13:46 UTC
Scheduled - We are upgrading our Sui Testnet infrastructure to testnet-v1.80.1 on 2026-09-22. This release introduces Protocol v137, which includes consensus-affecting changes such as refined gas charging for constants, network-wide acceptance of TransactionExpiration::Validity, stricter signing-time validation, and enhanced object-funds withdrawal checks. The release also expands gRPC and GraphQL capabilities.

Brief interruptions to RPC availability may occur on that date.

RPC Changes:
- SuiTransactionBlockEffects.shared_objects — Field derivation now includes implicitly read system objects (such as the accumulator root) once a consumer activates. Consumers treating this field as declared shared inputs must filter against transaction inputs.
- GetPackage, GetDatatype, GetFunction, ListPackageVersions (gRPC MovePackageService) — Now available on archival KV-RPC infrastructure (sui-kv-rpc), previously available only on full nodes.
- Historical subscription backfill (GraphQL) — Can now consume V1 effects from archival KV-RPC.
- QueryEndReason on empty natural interval queries (gRPC) — Queries ending on an empty natural interval now emit QueryEndReason::CheckpointBound with watermark.checkpoint = None instead of CursorBound.
- Transaction effects (gRPC v2 RPC) — V1 transaction effects now include their derived lamport version in v2 RPC responses.

[Urgent] Katana - Mainnet - Upgrade to v2.2.3
Completed - The scheduled maintenance has been completed.
Sep 24, 13:45 UTC
Scheduled - We are upgrading our Katana Mainnet infrastructure to conduit-op-reth v2.2.3. This is a point release that includes a critical bug fix from upstream op-reth v2.4.3 addressing deposit transaction handling. The fix ensures deposit transactions carry their required 0x7e type prefix for proper consensus validation.

During the maintenance window, brief interruptions to RPC availability may occur.

RPC Changes:
Deposit transaction validation — Deposit transactions are now required to carry the 0x7e type prefix; transactions missing this prefix will be rejected during validation.

https://github.com/conduitxyz/conduit-op-reth/releases/tag/v2.2.3
Sep 10, 19:21 UTC
[Urgent] NEAR Testnet - Upgrade to 2.14.0-rc.2
Completed - The scheduled maintenance has been completed.
Sep 24, 13:44 UTC
Scheduled - We are upgrading our NEAR Testnet infrastructure to nearcore 2.14.0-rc.1 on 2026-09-18. This is a mandatory protocol upgrade (version 85 to 87) introducing significant consensus-breaking changes including removal of the gas reward mechanism, new receipt input size limits, early chunk producer reassignment, and new host functions for ML-DSA-65 and SHA-3 cryptographic operations. Brief interruptions to RPC availability may occur on that date.

RPC/API-facing changes:
- `tx_status` is now the stable name for what was `EXPERIMENTAL_tx_status`. The old name still works as a deprecated alias with the same request/response shape, so no immediate action needed, but users should plan to move to tx_status.
- Timeout responses are more informative. Calls to tx, EXPERIMENTAL_tx_status, and send_tx/broadcast_tx_commit with wait_until now return a TIMEOUT_ERROR with a cause field (NOT_OBSERVED, PENDING, DOES_NOT_TRACK_SHARD, or ERROR) instead of a bare timeout. This field is optional/absent when hitting older nodes, so clients should handle its absence gracefully.
view_access_key_list /
- EXPERIMENTAL_view_access_key_list now support pagination (after_key, limit, with last_key returned for the next page). This is a breaking behavioral change: an unpaginated request now fails for any account with more than 100 access keys (the default limit) — any user client that queries access keys for high-key-count accounts needs to adopt pagination.

In progress - Scheduled maintenance is currently in progress. We will provide updates as necessary.
Sep 23, 14:01 UTC
Scheduled - We are upgrading our Polkadot Mainnet infrastructure to polkadot-stable2606-2, along with our Polkadot REST API to v0.3.0. The node update is a patch release for the stable2606 line containing fixes across XCM, staking, coretime, assets, and networking subsystems. Notable improvements include corrected XCM weight calculations for claim_assets, a pallet-broker auto-renewal security fix, and WebRTC transport now enabled by default on full nodes.

During the maintenance window, brief interruptions to RPC and REST API availability may occur.

RPC/API Changes:
- Breaking: in the REST API, an extrinsic's method field is now omitted rather than populated with placeholder data when that extrinsic could not be decoded. Users relying on strict schema validation or exhaustive struct matching against this field should review their integration.
- Fixed a bug where an undecodable extrinsic caused every later extrinsic in the same block to incorrectly inherit its events, success status, and fee data. Affected entries now retain their own data along with a decodeError detail.
- Events emitted after a block's last extrinsic (previously dropped) are now returned in a new afterExtrinsics field.

In progress - Scheduled maintenance is currently in progress. We will provide updates as necessary.
Sep 20, 10:00 UTC
Scheduled - We are upgrading our Solana Devnet and Testnet infrastructure to Agave v4.3.0-rc.1

During the maintenance window, brief interruptions to RPC availability may occur.
RPC Changes:
- getBlock, getTransaction, blockSubscribe — requests that combine encoding: "base58" (or "binary") with maxSupportedTransactionVersion >= 1 are now rejected with JSON-RPC error -32602, "base58 encoding is not supported with maxSupportedTransactionVersion >= 1". Use json, jsonParsed or base64 encoding for Transaction V1 requests; base58 with maxSupportedTransactionVersion: 0 continues to work as before.
- getInflationReward — the address list is now capped at 32 addresses per request; longer lists return JSON-RPC error -32602, "Too many inputs provided; max 32". Split larger queries into batches of 32.
- confirmed commitment — a slot is now reported as confirmed only once the node's local bank for that slot is frozen with a hash matching the cluster's. As a result, confirmed-commitment reads and accountSubscribe / programSubscribe notifications may arrive marginally later than before.
- Streams — Yellowstone gRPC moves to v16.0.0-rc9. The changes are additive only (a new block_footer message and new bank_id fields); existing subscriptions continue to work unchanged and no client update is required.

No JSON-RPC method is added, removed, or changed in its parameters in this release.

[Standard] Ethereum Mainnet and Testnets - Upgrade to Erigon v3.6.1
Completed - The scheduled maintenance has been completed.
Sep 16, 07:00 UTC
In progress - Scheduled maintenance is currently in progress. We will provide updates as necessary.
Sep 16, 01:02 UTC
Scheduled - We are upgrading our Ethereum Mainnet and Testnet infrastructure to Erigon v3.6.1. This release delivers more reliable Caplin block production, pruned-node snapshot reclamation, plain commitment snapshots for faster state access, and several RPC improvements.

During the maintenance window, brief interruptions to RPC availability may occur.

RPC Changes:
- eth_getBalance — Now defaults an omitted block parameter to `latest` instead of requiring explicit specification.
- eth_getCode — Now defaults an omitted block parameter to `latest` instead of requiring explicit specification.
- eth_getStorageAt — Now defaults an omitted block parameter to `latest` instead of requiring explicit specification.
- eth_getTransactionCount — Now defaults an omitted block parameter to `latest` instead of requiring explicit specification.
- eth_getProof — Now defaults an omitted block parameter to `latest` instead of requiring explicit specification.
- eth_getStorageValues — Now defaults an omitted block parameter to `latest` instead of requiring explicit specification.
- eth_newFilter — Idle filters now expire after five minutes; clients must poll within the timeout or recreate the filter. Configure `--rpc.subscription.filters.timeout` or set to `0` to disable eviction.
- eth_newBlockFilter — Idle filters now expire after five minutes; clients must poll within the timeout or recreate the filter. Configure `--rpc.subscription.filters.timeout` or set to `0` to disable eviction.
- eth_newPendingTransactionFilter — Idle filters now expire after five minutes; clients must poll within the timeout or recreate the filter. Configure `--rpc.subscription.filters.timeout` or set to `0` to disable eviction.
- JSON-RPC block number format — Quoted decimal block numbers such as `“3”` are now rejected; use `“0x3"`, a bare integer, or a named tag instead.
- Streaming trace errors — Error responses no longer include `result: null` alongside `error`.
- eth_fillTransaction — New method added; fills missing transaction fields and returns the unsigned raw transaction plus its JSON form, compatible with geth.
- eth_getWitness — With `--prune.include-commitment-history`, now builds and verifies a lean witness for any block within retained history.
- trace_block — Can now include beacon-withdrawal balance changes through the optional `IncludeWithdrawals` trace setting.
- trace_replayBlockTransactions — Can now include beacon-withdrawal balance changes through the optional `IncludeWithdrawals` trace setting.
- Receipt and log RPCs — Historical receipts are off by default on fresh datadirs in every prune mode; without the cache, receipt and log RPCs re-execute within the state-history window at higher latency. Blocks-mode operators needing receipts and logs back to genesis must use `--prune.include-receipts --prune.receipts.distance=keep-all`.
- Pending transaction reporting — Transactions waiting in the base-fee sub-pool were previously reported as queued instead of pending, understating pending transaction counts returned to clients and tooling. This is now corrected.

During the maintenance window, brief interruptions to RPC availability may occur.

RPC Changes:
- SuiTransactionBlockEffects.shared_objects — Field is now derived from accessed consensus objects, which can include implicitly read system objects such as the accumulator root. Consumers treating this field as declared shared inputs must filter against transaction inputs to avoid breaking logic.
- Transaction effects gRPC response — V1 transaction effects now include their derived lamport version in v2 RPC responses.
- QueryEndReason behavior — Terminal metadata on queries ending on an empty natural interval now emits `QueryEndReason::CheckpointBound` with `watermark.checkpoint = None` instead of `CursorBound`; no client migration required.
- GraphQL Subscription root type — The `Subscription` root type (`checkpoints`, `events`, `transactions`) is now part of the production schema; operators must enable it per deployment.
- GraphQL historical subscription backfill — Can now consume V1 effects from archival KV-RPC.
- Transaction validation — Additional signing time checks now reject structurally invalid transactions earlier.

[Urgent] Starknet Mainnet - Upgrade to Pathfinder v0.24.0
Completed - The scheduled maintenance has been completed.
Sep 14, 20:00 UTC
In progress - Scheduled maintenance is currently in progress. We will provide updates as necessary.
Sep 14, 14:00 UTC
Scheduled - We are upgrading our Starknet Mainnet infrastructure to Pathfinder v0.24.0. This release enables support for Starknet 0.14.4, improves RPC WebSocket reliability and connection limits, and hardens the feeder-gateway trace fallback against slow or untrusted responses.

During the maintenance window, brief interruptions to RPC availability may occur.

RPC Changes:
- WebSocket connections — Server now initiates pings to detect inactive clients; clients MUST respond to pings per RFC 6455 or face disconnection. Clients that do not read from the connection for longer than the ping interval times the missed ping limit will be disconnected. The keepalive cannot be disabled; ping interval, initial frame timeout, and max missed pings all reject 0 as a value.
- WebSocket connection limit — Concurrently open RPC WebSocket connections are now limited to 1024 by default; upgrade requests exceeding this limit are rejected with HTTP 503.
- WebSocket initial frame timeout — RPC WebSocket connections that do not send anything after being established now time out.
- WebSocket subscription teardown — Subscriptions are now torn down when their WebSocket connection closes, instead of at the next send attempt.
