We are upgrading our Ethereum Mainnet and Testnet nethermind infrastructure to v1.39.3. This release consolidates several updates published since v1.38.0, most notably a security update to underlying .NET dependencies addressing multiple CVEs, along with reliability and hardening fixes to request decoding and memory handling. During the maintenance window, brief interruptions to RPC availability may occur. RPC changes: - The non-spec error field has been removed from transaction receipt responses. - eth_simulateV1 now bounds total block expansion across a simulation request. https://github.com/NethermindEth/nethermind/releases/tag/1.39.3

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. https://github.com/hirosystems/stacks-blockchain-api/releases/tag/v9.2.0

We are upgrading our Avalanche Mainnet infrastructure to AvalancheGo v1.15.0 to support the Helicon network upgrade, scheduled to activate at 11 AM ET (3 PM UTC) on Tuesday, September 22nd, 2026. Helicon introduces C-Chain Async Execution (ACP-194), Auto-Renewed Staking (ACP-236), Validator Uptime Requirements Increase (ACP-267), Reduced Minimum Validator Staking Duration (ACP-273), Dynamic Minimum C-Chain Gas Price (ACP-283), and Reduced Minimum Consumption Rate (ACP-285). This release includes significant breaking changes to C-Chain APIs and configuration. During the maintenance window, brief interruptions to RPC availability may occur. RPC Changes: - pending block — Now resolves to the last executed block by default. - latest block — Now resolves to the last executed block. - safe and finalized blocks — Both now resolve to the last settled block. - avax.getAtomicTxStatus — This RPC is deprecated; use avax.getAtomicTx instead. https://github.com/ava-labs/avalanchego/releases/tag/v1.15.0

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`. https://github.com/erigontech/erigon/releases/tag/v3.6.0

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. https://github.com/paradigmxyz/reth/releases/tag/v2.5.2

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. https://github.com/ethereum-optimism/optimism/releases/tag/op-node/v1.19.6 https://github.com/ethereum-optimism/optimism/releases/tag/op-reth/v2.4.3
