Op-stack Subblocks (Flashblocks): 200ms interval and payload changes

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

TON V1 API decommission - Migrate to V2

In progress - Scheduled maintenance is currently in progress. We will provide updates as necessary.
Aug 12, 2026 - 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.

Highlights
- Raptorcast v1 publish — nodes now publish proposals in the v1 raptorcast wire format on both
the primary and secondary paths.
- 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,
matching geth and reth.
Ref: monad-bft PR #3164
[RPC] Fix EIP-1898 compatibility for BlockTagOrHash.
Ref: monad-bft PR #3163
[RPC] eth_createAccessList now accepts state overrides.
Ref: monad-bft PR #3179

Notable robustness changes
[Consensus] A validator publishes only the first accepted proposal to its full nodes, so an

[Standard] Sei - Pacific and Atlantic - Upgrade to v6.6.3

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.

[Urgent] BSC Mainnet and Testnet - Upgrade to reth-v0.1.2

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.

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.

[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.

Aug 25, 11:00 UTC

Scheduled - We are upgrading our Hedera Mainnet and Testnet infrastructure to JSON-RPC Relay v0.78.2 and Hedera Mirror Node v0.161.3. These releases unifies nonce-related error codes, consolidates gas limit configuration, includes dependency updates, and fixes a data integrity issue in the contract results endpoint by excluding records with null transaction indices.

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

RPC Changes:
- JSON-RPC error responses for nonce-related failures — Error code standardized to -32000 for all nonce validation errors, ensuring consistent error handling across clients.
- Transaction gas limit behavior — Per-transaction gas limits are now consolidated into a single configurable MAX_TRANSACTION_GAS_LIMIT parameter; ensure your client configuration aligns with operator settings.
- Contract results endpoint — Records with null transaction_index values are now excluded from responses, ensuring only valid transaction data is returned to callers.
- eth_sendTransaction — Nonce-related error responses are now uniformly returned with error code -32000 for improved client compatibility.

[Urgent] Moca - Testnet - Upgrade to v1.4.0

Resolved - We are upgraded our Moca Testnet infrastructure to v1.4.0.

This is a coordinated network upgrade that bundles a broad set of fixes across the storage, payment, and permission modules, along with a scheduled hardfork handler.

During the maintenance window, brief interruptions to RPC may have occurred.

RPC Changes:
- Address validation is now stricter across the board — a dedicated 20-byte address verifier is enforced, so malformed addresses that were previously accepted by some endpoints will now be rejected.
- Permission checks for resource-pattern matching have been corrected, including how empty-Resources permissions are scoped — this may change authorization results returned for some API calls.
- CopyObject behavior now aligns with CreateObject's destination handling, so copy operations resolve destination buckets/objects consistently.
- Payment settlement logic has been corrected around frozen and resuming accounts, which may affect balance and settlement figures returned for impacted accounts.

In progress - Scheduled maintenance is currently in progress. We will provide updates as necessary.
Aug 21, 11:00 UTC

Scheduled - We are upgrading our Aleo Mainnet infrastructure to snarkOS v4.9.1.

This release introduces a consensus-level change to smart contract deployment limits, replacing dynamic density-based limits with static constants. A mainnet consensus version activation is scheduled for block height 21,342,000 (predicted August 24, 2026). All nodes must be upgraded before this activation height to remain synchronized with the canonical chain.

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

RPC Changes:
- Smart contract deployment limits — Maximum deployment variables and constraints are now enforced by static constants (MAX_DEPLOYMENT_VARIABLES_V2 and MAX_DEPLOYMENT_CONSTRAINTS_V2, both set to 2^22 / 4,194,304). Deployment requests exceeding these limits will be rejected; users should verify their smart contract complexity does not exceed the new static ceiling.
