Scheduled Maintenance

[Standard] Celestia - Mainnet and Mocha Testnet - Upgrade to v0.32.1 / v0.33.0-mocha Sep 14, 2026 01:00-07:00 UTC

We are upgrading our Celestia Mainnet infrastructure to v0.32.1 and our Mocha Testnet infrastructure to v0.33.0-mocha. The Mainnet release removes the deprecated DA API namespace, improves bridge node reliability with multi-source block ingestion, and includes several security fixes and performance improvements; the release notes recommend upgrading as soon as possible. The Mocha Testnet release focuses on sync performance improvements, delivering roughly 2.5x faster sync throughput. During the maintenance window, brief interruptions to RPC availability may occur on both networks.

RPC Changes: da.* namespace (Mainnet) — API decommissioned: all da.* JSON-RPC methods are removed in this release; calls to these methods will fail. Users should update integrations immediately.

Mainnet release: https://github.com/celestiaorg/celestia-node/releases/tag/v0.32.1 Mocha Testnet release: https://github.com/celestiaorg/celestia-node/releases/tag/v0.33.0-mocha

[Urgent] Starknet Mainnet - Upgrade to Pathfinder v0.24.0 Sep 14, 2026 14:00-20:00 UTC

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.

[Standard] Hedera Mainnet and Testnet - Upgrade Mirror Node to v0.162.0 Sep 15, 2026 00:00-04:00 UTC

We are upgrading our Hedera Mainnet and Testnet Mirror Node infrastructure to v0.162.0. This release focuses on security fixes, bug corrections, and performance improvements. Notable enhancements include optimized contract storage lookups in web3 that eliminate an unbounded per-contract cache, support for HIP-1261 simple fees in gas price calculations for contract REST APIs, and improved block node streaming.

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

RPC Changes:
- contract storage lookups (web3) — Performance optimized by removing an unbounded per-contract cache that could cause quadratic query growth under load.
- gas price calculation (contract REST APIs) — Now supports HIP-1261 simple fee schedules when calculating gas prices.
- HCS transaction alias resolution — Aliases on HCS transactions are now properly resolved in the importer.
- contract results endpoints — Responses no longer include transaction_index=null entries.
- block root hashing — Refactored to use a fixed 16-slot sub Merkle tree for improved consistency.

[Standard] Polygon Mainnet & Amoy - Upgrade to Bor v2.10.1 Sep 15, 2026 14:00-22:00 UTC

We are upgrading our Polygon infrastructure to Bor v2.10.1. This release introduces BlockSTM v2, a parallel transaction execution engine enabled by default that improves performance and consistency, along with devp2p peer jailing for enhanced network stability.

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

RPC Changes:
- eth_baseFee — New RPC method now available to query the current base fee per gas.

[Standard] Op-stack chains (Mainnets and Testnets) - Upgrade to op-node-v1.19.6 & op-reth-v2.4.3 Sep 16, 2026 00:00-06:00 UTC

We are upgrading our Op-stack infrastructure to op-node v1.19.6 & op-reth-v2.4.3. The upgrade addresses security-sensitive dependency updates, hardens derivation logic against batch-splicing attacks, and fixes a sequencer shutdown hang.

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

RPC Changes:
Deposit transaction decoding — Logic has been hardened to improve validation and security of deposit transaction processing in RPC responses.

[Standard] Ethereum Mainnet and Testnets - Upgrade to Erigon v3.6.0 Sep 16, 2026 01:00-07:00 UTC

We are upgrading our Ethereum Mainnet infrastructure to Erigon v3.6.0. 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`.

[Standard] Ethereum Mainnet and Testnets - Upgrade to Reth v2.5.2 Sep 16, 2026 01:00-05:00 UTC

We are upgrading our Ethereum reth infrastructure to v2.5.2. This upgrade includes maintenance improvements from v2.5.1 and v2.5.2, including a fix for a startup issue that could occur after finalization leaves gaps in write-ahead logs, improved handling for networks with dynamically scheduled forks to update their fork configuration without a restart, more reliable payload building when a build resolves early, a fix for how storage data is handled during batched persistence, and internal file-handling and logging improvements.

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

This release does not include any changes to end-user facing RPC methods or API behavior.

[Standard] Stacks Mainnet and Testnet - Upgrade stacks-blockchain-api to v9.2.0 Sep 17, 2026 00:00-04:00 UTC

We are upgrading our Stacks Mainnet and Testnet API infrastructure to stacks-blockchain-api v9.2.0. This release introduces three new v3 API endpoints for batch transactions, staking bond events, and staking rewards totals, and fixes a bug in Bitcoin rewards counting that incorrectly mixed PoX reward distribution amounts with burned amounts.

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

RPC Changes:
- Batch transactions endpoint (v3) — New endpoint added for querying batch transaction data.
- Staking bond events endpoint (v3) — New endpoint added for retrieving staking bond event information.
- Staking rewards totals endpoint (v3) — New endpoint added for querying aggregated staking rewards data.
- Bitcoin rewards — Bug fix corrects the count and distribution of Bitcoin rewards; responses from rewards-related endpoints will now reflect accurate PoX amounts separate from burned amounts.

TON V1 API decommission - Migrate to V2
Completed - This has been completed
Sep 8, 14:19 UTC
In progress - Scheduled maintenance is currently in progress. We will provide updates as necessary.
Aug 12, 17:01 UTC
Scheduled - We will be decommissioning our TON V1 API (Python-based) in favor of the more performant V2 API (C++ based)

We urge you to migrate to TON V2 HTTP API ASAP for Better Performance and Stability.
The TON team officially recommends the V2 implementation, and Quicknode has supported the V2 C++ build of the TON HTTP API for several months.

-- Timeline:
 Quicknode plans to decommission the legacy V1 implementation on August 31st in favor of V2. We recommend teams begin planning their migration now to stay ahead of the transition.

-- Note on compatibility: V1 and V2 are NOT drop-in replacements - method availability and response formats differ between the two. Before migrating, review the V1 and V2 API reference docs for your specific integration and test thoroughly to confirm compatibility with your existing implementation.

Op-stack Subblocks (Flashblocks): 200ms interval and payload changes
Completed - The scheduled maintenance has been completed.
Sep 8, 14:18 UTC
Update - Subblocks (formerly known as Flashblocks) which stream pre-confirmations on OP Stack chains have two changes that directly impact anyone consuming the stream. The rollout of these changes starts on OP Sepolia on *Monday, August 17, 2026* and on OP Mainnet on *Monday, August 31, 2026*.

This change is backwards compatible. The WebSocket stream URL and the RPC endpoints are not changing. Unless you rely on the four payload fields below, nothing changes for you and no action is needed.

What's changing
- The subblock interval drops from 250ms to 200ms. Subblocks are produced more frequently.
- Four payload fields are set to their zero value. `state_root`, `block_hash`, `withdrawals_root`, and `withdrawals` are zeroed in the subblock payload. The stream stays wire compatible, so this does not raise a parse error — an integration that reads any of them gets a zero value instead of failing loudly. The failure mode is silent, so audit rather than wait for an error. Every other field, including `receipts_root` and `logs_bloom`, still carries a real value.

The rollout is gradual
This is a rolling change rather than a single switch, so you may see both the previous and the new behavior for a period.

Action required
If you consume the `subblock` stream, audit your integration for reads of `state_root`, `block_hash`, `withdrawals_root`, and `withdrawals`.

Timeline
- Monday, August 17, 2026 — rollout begins on OP Sepolia
- Monday, August 31, 2026 — rollout begins on OP Mainnet

https://github.com/morph-l2/go-ethereum/releases/tag/morph-v2.2.6
Per-block tx payload budget raised from 120KB to 720KB
This limit is enforced in the binary, not via genesis/chain config. Nodes running older versions will reject or mishandle blocks assembled under the new limit, making this effectively a consensus-breaking change requiring all operators to upgrade.

Txpool blacklist feature removed
The --txpool.blacklist flag and all associated RPC/storage logic have been deleted. Nodes with this flag in their startup configuration will likely fail to start or emit errors. Leftover eth/db/blacklist/ data in the database can be deleted manually but is otherwise harmless.

Auth WebSocket endpoint now requires JWT
The authenticated Engine API WebSocket path now enforces JWT authentication, matching the existing HTTP behavior. Clients or tooling connecting to the Engine API WS endpoint without JWT will be rejected.

https://github.com/morph-l2/morph/releases/tag/v0.6.3

L1 Rollup authorization model replaced — staked Submitter role replaces sequencer-set authorization
The Rollup contract now only authorizes active staked Submitters. bitmap/BLS/BatchSignatureInput inputs are removed. The former sequencer-set field in batch headers is written as zero after cutover. Historical ABI/selector decoding is preserved, but new submissions require the staked Submitter flow.

Batch public-input preimage change — sequencer public-input field zeroed
The prover zeros the former sequencer public-input field after the cutover. Batch-header layout and public-input preimage structure remain the same, but the sequencer field value changes to zero.

Prover DA decode library switched from zstd-rs to morph-da-encoder
The prover now uses morph-da-encoder for DA decoding instead of zstd-rs. Operators running the prover must ensure the new library dependency is present.

Challenge-handler migrated to remote-signer SDK (sign_v1) with active proof signer validation
The challenge-handler now uses the remote-signer SDK sign_v1 interface and validates the active proof signer. Operators must configure the remote signer endpoint accordingly.

- JSON-RPC error codes corrected across eth_call, eth_estimateGas, eth_simulateV1,
debug_* and txpool_*.

Notable RPC/SDK changes
[RPC] Fix JSON-RPC error codes and messages returned by the call, simulate, debug, txpool and
websocket handlers.
Ref: monad-bft PR #3228
[RPC] Fix zero-fee eth_calls — a zero maxFeePerGas is no longer raised to the base fee,

Completed - The scheduled maintenance has been completed.
Sep 3, 04:00 UTC
In progress - Scheduled maintenance is currently in progress. We will provide updates as necessary.
Sep 3, 00:00 UTC
Scheduled - We are upgrading our Sei Pacific and Atlantic infrastructure to seid v6.6.3.

This is a patch release with no state-machine or consensus-breaking changes, recommended for RPC operators and validators. It includes a memory leak fix in snapshot writes, improved snapshot durability and validation, new freeze mode for historical EVM RPC, a frozen RPC router for block-scoped request fanout, and hardening fixes for nested block reference parsing and JSON-RPC batch handling. During the maintenance window, brief interruptions to RPC availability may occur.

RPC Changes:
- EIP-1898 block references — Nested block reference parsing depth is now capped at 16 levels to prevent quadratic parse time and protect against adversarial inputs.
- JSON-RPC batches — Router batch allocations are now bounded with write timeouts to prevent unbounded memory allocation from slow clients.
- Freeze mode — Historical EVM RPC nodes can now be held at an upgrade boundary via freeze mode, continuing to serve state while staying out of mempool gossip; the frozen RPC router fans block-scoped requests to the matching frozen node.

[Urgent] Sui Testnet - Upgrade to testnet-v1.79.0
Completed - The scheduled maintenance has been completed.
Sep 2, 07:00 UTC
In progress - Scheduled maintenance is currently in progress. We will provide updates as necessary.
Sep 1, 23:00 UTC
Scheduled - We are upgrading our Sui Testnet infrastructure to testnet-v1.79.0. This release introduces protocol version 136. During the maintenance window, brief interruptions to RPC availability may occur.

## RPC Changes

**`simulateTransaction` — modified**
Transaction expiration responses now return VALIDITY instead of VALID_DURING. Clients that reconstruct the expiration from the response must include the new allowed_proposers field to ensure transaction digest matching; clients that use the response unchanged are unaffected.

**`PTB TxContext` — modified**
TxContext restrictions are now enforced at the protocol level. TxContext may appear at most once as &mut TxContext or any number of times as &TxContext in a PTB Move call signature, and never by value or in return position. Transactions violating these rules now fail immediately with InvalidTxContext error.

Completed - The scheduled maintenance has been completed.
Sep 2, 04:00 UTC
In progress - Scheduled maintenance is currently in progress. We will provide updates as necessary.
Sep 2, 00:00 UTC
Scheduled - We are upgrading our BSC Mainnet and Testnet infrastructure to reth-bsc v0.1.2.

This release implements the BEP-675 BidBlock MEV path, enabling builders to submit fully-built blocks via `mev_sendBidBlock`, and includes a critical state-root correctness fix.
The fix resolves a consensus issue where certain state writes (contract code upgrades, EIP-2935 history storage, and validator reward distribution) were committed without proper state-root synchronization, which caused consensus splits on testnet. The release also brings RPC parity improvements and a security dependency bump.

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

RPC Changes:
- eth_getLogs — Topic-position handling has been corrected for improved RPC parity with geth.
- Block header responses — Now include `totalDifficulty` field for consistency with geth.
- Pending block log filters — Log filters on pending blocks are now rejected as per geth RPC standards.

[Urgent] Sui - Mainnet - Upgrade to mainnet-v1.78.1
Completed - The scheduled maintenance has been completed.
Sep 1, 22:13 UTC
Scheduled - We are upgrading our Sui Mainnet infrastructure to mainnet-v1.78.1.

This release advances the protocol to version 135, which disables `defer_unpaid_amplification` on all networks and applies package ID cost and consensus block limit changes on mainnet. The upgrade also includes GraphQL subscription improvements, gRPC enhancements, and bug fixes. During the maintenance window, brief interruptions to RPC availability may occur.

RPC Changes:
- GraphQL transactions subscription — Transaction subscriptions now support historical cursors, allowing queries from a specific point in transaction history.
- GraphQL transactions/events queries — Fixed a race condition that could non-deterministically omit recently-created data when served via `--ledger-grpc-url`.
- gRPC TransactionExecutionService simulate/resolve — Error messages for version-mismatch and digest-mismatch now include the offending object ID and render provided/actual values consistently for improved debugging.

Celestia Mocha - Mocha-4 --> Mocha-5 Network Switch-over
Completed - The scheduled maintenance has been completed.
Aug 31, 17:00 UTC
In progress - Scheduled maintenance is currently in progress. We will provide updates as necessary.
Aug 31, 09:00 UTC
Scheduled - Quicknode is switching the Celestia Mocha Testnet from mocha-4 to mocha-5, in line with the Celestia team's network restart.

During the maintenance window, your Mocha endpoint may return errors or stale data while nodes switch over to mocha-5. You will see the latest block height drop, since mocha-5 restarts at block height 1.

*Celestia mainnet is not affected.*

After the switch:
- Endpoints serve mocha-5 (chain ID mocha-5). Update your chain ID to mocha-5 if it is hardcoded in your apps.
- Historical mocha-4 data is not available on mocha-5.
- Celestia shuts down mocha-4 on Sept 1, 2026 — move any remaining mocha-4 workflows before then.

Gravity Mainnet — Block Height Stalled
Resolved - This incident has been resolved.
Aug 31, 14:00 UTC
Monitoring - This continues to be an upstream issue on the Gravity network, not related to our infrastructure. Block production has partially resumed, with some nodes still catching up. We'll keep watching closely and update as the situation develops.
Aug 31, 13:41 UTC
Identified - The underlying issue has been identified. We are working with the Foundation to restore normal block progression. Further updates will be provided as the situation develops.
Aug 31, 07:26 UTC
Investigating - Gravity Mainnet appears to have stalled at block 39,007,386 - The Quicknode team is investigating and will update with more information once it is available.

[Urgent] Monad - Mainnet - Upgrade to v0.16.1
Completed - The scheduled maintenance has been completed.
Aug 31, 07:00 UTC
In progress - Scheduled maintenance is currently in progress. We will provide updates as necessary.
Aug 31, 01:00 UTC
Scheduled - We are upgrading our Monad Mainnet infrastructure to v0.16.1.

This is a mandatory network upgrade that activates the MONAD_TEN hard fork on mainnet at 2026-09-02 14:30 UTC (Unix timestamp 1788359400). Nodes not upgraded before this timestamp will diverge from the network and continue applying MONAD_NINE consensus rules, resulting in chain divergence.
This release also enforces page-encoded timeline requirements on mainnet.

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

RPC Changes:
All JSON-RPC methods — Consensus rules change at MONAD_TEN activation (2026-09-02 14:30 UTC); MIP-8 page-encoded storage becomes active. RPC responses and state queries after this timestamp will reflect page-encoded storage semantics, which differ from MONAD_NINE behavior. Clients relying on pre-activation state structure or transaction ordering may observe different results post-activation.

Upstream maintenance Aug 26–28 — possible latency increase (US-East)
Completed - The scheduled maintenance has been completed.
Aug 28, 12:00 UTC
Update - We're performing upstream maintenance affecting a subset of networks over two overnight windows: Aug 26–27 and Aug 27–28, 23:00–09:00 UTC each night.

Nothing changes on your side. Your endpoint URLs, IP addresses, and credentials stay the same — there's no configuration change and no action to take.

Am I affected? The effect is on latency only, so it would show in your own response-time metrics. Applications running in US-East are the most likely to notice a difference during these windows. Most networks will see no meaningful change.

Two networks may see a larger increase:

XRP Ledger Mainnet (Aug 27–28 window only): traffic is served from Singapore. Customers outside Asia-Pacific should expect a substantial latency increase for that window.
NEAR Mainnet (from Aug 27): some requests are served from Europe and Asia, adding latency.

Errors, timeouts, and failed requests are not expected. If you see any, submit a ticket and we'll prioritize it immediately: https://quicknode.portal.usepylon.com/forms/submit-a-support-ticket

We'll post a further update after tonight's window completes.
Aug 26, 18:46 UTC
In progress - Scheduled maintenance is currently in progress. We will provide updates as necessary.
Aug 25, 20:00 UTC
Scheduled - Due to scheduled maintenance at an upstream infrastructure provider, some services in the IAD region will fail over to other regions during this window. Most customers will see no impact beyond moderately increased latency on the networks below.

• Night 1 (Aug 25 23:00 – Aug 26 09:00 UTC): Solana Mainnet, Polygon Mainnet, Monad Testnet, Ethereum Mainnet, Injective Mainnet, TON Mainnet, XRP Mainnet.
• Night 2 (Aug 26 23:00 – Aug 27 09:00 UTC): NEAR Mainnet, Solana Mainnet, Ethereum Mainnet, Polygon Mainnet, Sei Atlantic-2 (elevated latency — served from an alternate region).
• Night 3 (Aug 27 23:00 – Aug 28 09:00 UTC): Flow Mainnet (reduced access-node capacity, RPC unaffected), TON Mainnet, Fantom, Ethereum, Base, Hedera Testnet, Sui, XRP Mainnet (IAD served from alternate regions).

No customer action is required. Updates will be posted here as each window completes.

Reach out to our Support team if you notice any issues during the maintenance period.
