Sui Mainnet - JSON-RPC API Deprecation Notice

Monitoring - Sui has officially marked JSON-RPC as deprecated and is requiring developers to migrate to either gRPC or GraphQL RPC by July 2026. You can read more in Sui's blogs below:
https://docs.sui.io/develop/accessing-data/data-serving
https://docs.sui.io/develop/accessing-data/json-rpc-migration

The good news: Quicknode has you covered with support of both gRPC and GraphQL for Sui, and we've just made gRPC even more accessible with two new additions:

- gRPC-web transport support - enabling browser-based clients to connect seamlessly over port 443
- gRPC traffic now served over port 443 - simplifying firewall and infrastructure configuration

If you need help getting started with gRPC or GraphQL on Quicknode, please check out our docs:

Polygon Erigon Client/Method Deprecation Notice

In progress - In line with Polygon Labs' decision to sunset the Erigon client on Polygon PoS (by Aug 1, 2026), we're migrating our Polygon Mainnet and Testnet (Amoy) infrastructure from Erigon to Bor, the recommended Polygon client.
This improves node stability and sync reliability, but Bor (a geth-based client) does not support the Erigon-specific method namespaces.

As a result, the following methods will no longer be available:
- The entire trace_* namespace — trace_filter, trace_block, trace_replayBlockTransactions, trace_transaction, trace_call, etc.
- The entire erigon_* namespace — e.g. erigon_getHeaderByNumber

Effective dates:
- Polygon Testnet (Amoy) — July 1, 2026
- Polygon Mainnet — July 15, 2026

Recommended migration:
- Replace trace_* calls with the debug_trace* namespace — debug_traceBlockByNumber, debug_traceTransaction, debug_traceCall
- For range-based trace_filter use cases, use eth_getLogs against indexed event logs
Replace erigon_* calls with standard equivalents (e.g. eth_getBlockByNumber in place of erigon_getHeaderByNumber)

Please also note:
On Bor, eth_getProof is supported only for the most recent 128 blocks; historical eth_getProof queries are not served.

If you rely on any of these methods, please plan your migration ahead of the dates above.

[Standard] Ethereum - Mainnet and Testnets - Upgrade to Erigon v3.5.4 & Geth v1.17.5 Aug `3`, `2026` `09:00`-`15:00` UTC

We are upgrading our Ethereum Mainnet and Testnet infrastructure to Erigon v3.5.4 and Geth v1.17.5.

The Erigon update is a bugfix release that resolves issues affecting RPC subscriptions and request handling: missing log/receipt notifications on eth_subscribe("logs") and eth_subscribe("newReceipts") for blocks resumed mid-execution, a panic in the trace RPC methods when handling nil transactions, and a deadlock affecting JSON-RPC batch requests.
The Geth update is a maintenance release that includes several RPC validation changes.

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

RPC Changes:
- eth_subscribe('logs') — Fixed missing notifications for logs in mid-block resumed blocks.
- eth_subscribe('newReceipts') — Fixed missing notifications for receipts in mid-block resumed blocks.
- Transaction submission — requests that combine a legacy gasPrice with an authorizationList are now rejected.
- Block parameter validation — requests specifying a block parameter with neither a number nor a hash are now rejected.

Please see the detailed change logs at:
https://github.com/erigontech/erigon/releases/tag/v3.5.4

[Standard] Base - Sepolia (Testnet) - Upgrade to v1.2.0 Aug `3`, `2026` `14:00` - Aug `5`, `2026` `14:00` UTC

We are upgrading our Base Sepolia infrastructure to v1.2.0 on 08/03/2026, with the maintenance window expected to run through 08/04/2026. This upgrade includes a required database migration, which is a larger undertaking than a typical version bump, so we've scheduled additional time to complete it safely.

During this window, users may experience brief interruptions to RPC availability on Base Sepolia as nodes are migrated.

RPC Changes:
No breaking changes to existing RPC methods are expected. This release improves underlying node stability and sync reliability, with no anticipated impact to current API behavior.

Please see the detailed change log at:

[Standard] BNB Smart Chain - Mainnet - Geth v1.7.7 | Reth v0.1.1 Aug `3`, `2026` `14:00`-`18:00` UTC

We are upgrading our BNB Smart Chain Mainnet infrastructure to geth v1.7.7 and reth-bsc v0.1.1 to support the Pasteur hard fork scheduled for 2026-08-25 02:30:00 UTC.
This release implements BEP-673 changes including rejection of duplicate bridge validators and system contract upgrades, along with bug fixes across RPC, p2p, filters, and state management.

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

RPC Changes:
eth_gasPrice — fixed a default configuration issue that was causing this method to return a skewed value of 0 on reth-bsc nodes.

[Standard] Bitcoin Cash - Mainnet & Testnet - Upgrade to v29.1.0 Aug `4`, `2026` `00:00`-`04:00` UTC

We are upgrading our Bitcoin Cash Mainnet & Testnet infrastructure to Bitcoin Cash Node v29.1.0.

This minor release delivers RPC improvements and performance optimizations, including expanded RPC method outputs, new REST API endpoints for spent transaction outputs, and increased default RPC thread and work queue limits for better throughput.

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

RPC Changes:
- getmempoolinfo — Results now include a new key, total_fee, representing the sum of all fees paid by transactions currently in the mempool (in BCH).
- testmempoolaccept — Returns expanded information in JSON object results; consult RPC help for details on new fields.
- gettxout — New optional 4th parameter, patterns (boolean); when set to true, results include a new byteCodePatterns JSON object.
- getchaintxstats — Results now include a new key, window_final_block_height.
REST API — Two new endpoints introduced: /rest/spenttxouts/. and /rest/spenttxouts/withpatterns/. for efficiently fetching spent transaction outputs using block undo data.

[Standard] Hyperliquid Mainnet - Upgrade Nanoreth to nb-20260727 Aug `4`, `2026` `07:30`-`11:30` UTC

We are upgrading our Hyperliquid Mainnet infrastructure to Nanoreth nb-20260727. This release fixes request-handling panics in compliance mode when fetching nonexistent blocks and includes a backported tracer fix for improved stability.

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

[Urgent] Cosmos - Mainnet - Upgrade to v27.6.0 Aug `4`, `2026` `09:00`-`13:00` UTC

Cosmos Mainnet is undergoing a Network upgrade to Gaia v27.6.0.

This release increases the maximum CosmWasm contract size from 800 KiB to 1.6 MiB and allowlists additional gRPC queries for CosmWasm contract access, enabling broader contract functionality.

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

RPC Changes:
/cosmos.gov.v1.Query/Proposal — Now allowlisted for CosmWasm contract queries.
/cosmos.staking.v1beta1.Query/Validator — Now allowlisted for CosmWasm contract queries.

[Standard] 0g Galileo Testnet - Upgrade to v3.0.8 Aug `5`, `2026` `01:00`-`05:00` UTC

We are upgrading our 0g Galileo Testnet infrastructure to v3.0.8.

This release introduces delegate staking functionality and double-sign slashing support across both consensus and execution layers.

Users should expect brief interruptions to RPC availability during the maintenance window, and no unexpected downtime is anticipated beyond that.

RPC Changes:
- C-Chain async execution: RPC calls that depend on chain state, when made immediately after a block is accepted, will now return only once that block has finished executing. Users polling state right after block acceptance may notice a small added delay before results are available.
- The following API namespaces/methods are now deprecated: the admin API namespace, the warp API namespace, and avax.getAtomicTxStatus, along with several debug namespace methods (debug_dumpBlock, debug_preimage, debug_getBadBlocks, debug_accountRange, debug_storageRangeAt, debug_getModifiedAccountsByNumber, debug_getModifiedAccountsByHash, debug_getAccessibleState). Users relying on these methods should plan to migrate off them.
- APIs that read pending-block state are now deprecated.
C-Chain state sync is not supported in this release; a version adding state sync support will follow before Mainnet activation is scheduled.

[Urgent] Gravity Mainnet - Upgrade to v1.8.0

Completed - The scheduled maintenance has been completed.
Jul 24, 05:00 UTC

In progress - Scheduled maintenance is currently in progress. We will provide updates as necessary.
Jul 24, 01:00 UTC

Scheduled - We are upgrading our Gravity Mainnet infrastructure to v1.8.0 to support the Alpha hardfork, scheduled to activate on 2026-07-27 at 05:00:00 UTC (13:00:00 Beijing time).

This is a coordinated upgrade required for all nodes to remain in consensus. T

he Alpha hardfork introduces system transaction fee restructuring, deterministic leader-reputation anchoring, and execution-layer correctness improvements. During the maintenance window, brief interruptions to RPC availability may occur.

RPC Changes:
- eth_call — Post-Alpha system transactions now apply zero gas-price pricing rules; RPC replay and trace endpoints enforce the same gas rules as canonical execution to prevent SYSTEM_CALLER spoofing.
- eth_getTransactionByHash — Post-Alpha system transactions remain visible in block bodies with zero gas price and do not debit SYSTEM_CALLER; gas_used fields reflect actual metering.
- eth_traceTransaction — Historical trace and replay endpoints now apply post-Alpha system-transaction gas rules consistently with canonical execution.

debug_executionWitness — Fixed to avoid returning incomplete witness data.
- eth_subscribe (logs, newHeads) — Fixed missing WebSocket notifications and incorrect log indexing that could occur during parallel execution.
Block-data-only endpoints (e.g. block retrieval methods) — Fixed an issue causing errors on nodes pruned below the requested block's state history, when only block data was needed.
- JSON-RPC batch requests — Fixed a race condition in gzip-compressed batch responses containing two or more streamable methods that could cause a node crash.
- eth_sendRawTransactionSync — Timeout support has been added, matching EIP-7966-style timeout behavior.
- eth_getProof — Empty-proof normalization has been improved for geth alignment.
- eth_simulate — Multiple fixes have been applied for improved compatibility.
- eth_estimateGas — Several fixes have been applied for improved compatibility.

[Standard] Stacks Mainnet - Upgrade to core-v4.0.0 / API v9.0.0

Completed - The scheduled maintenance has been completed.
Jul 17, 11:30 UTC

In progress - Scheduled maintenance is currently in progress. We will provide updates as necessary.
Jul 16, 07:30 UTC

Scheduled - We are upgrading our Stacks Mainnet infrastructure to node version v4.0.0 and API version v9.0.0. The node release delivers bugfixes and improvements to ensure more consistent block production.
This node upgrade is mandatory ahead of the Stacks 4.0 hard fork, activating at block height 960,230, expected around July 29, 2026 at 13:00 UTC.

The API upgrade to v9.0.0 adds forward support for pox-5 (Bitcoin Staking) and the upcoming Stacks 4.0 hard fork, and introduces a new cursor-paginated /extended/v3 API surface.

During the maintenance window, brief interruptions to RPC/API availability may occur.
RPC/API Changes:

Starting at hard fork activation, the network will reject blocks containing transactions with non-normalized "high S" secp256k1 signatures. Users submitting raw/custom-signed transactions should ensure signatures are normalized to avoid rejection.
New /extended/v3 endpoints are now available for transactions, blocks, principals, and staking (pox-5) data, offering improved performance and pagination for large result sets.
A number of legacy /extended/v1 and /extended/v2 endpoints are now deprecated. They remain functional but will return a Warning HTTP header and may be throttled; they will be shut down at a later date to be announced.
The Rosetta API implementation has been removed. Users relying on Rosetta-compatible access should migrate to the new Stacks Mesh API.

The upgrade also deprecates centralized external-storage state sync in favor of peer-to-peer synchronization. This release additionally includes a required fix ahead of the network-wide protocol upgrade.

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

RPC Changes:
- EXPERIMENTAL_receipt_to_tx — Now accepts optional block_height, shard_id, and window hint parameters for improved receipt lookup performance; returns UnknownReceipt on column miss with hint set for long emit-to-execute delays. - EXPERIMENTAL_view_state — Pagination support added with after_key_base64 and limit request parameters; responses now include last_key for fetching subsequent pages.
