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

We are upgrading our Celestia Mocha Testnet infrastructure to celestia-app v10.1.0-mocha and celestia-node v0.33.2-mocha. The celestia-app release is a coordinated network upgrade tied to a signalled activation height and introduces Fibre, a new data availability service used by validators. The celestia-node release includes security fixes and resolves a deadlock issue in peer connection handling. During the maintenance window, brief interruptions to RPC availability may occur. Release: https://github.com/celestiaorg/celestia-app/releases/tag/v10.1.0-mocha https://github.com/celestiaorg/celestia-node/releases/tag/v0.33.2-mocha

We are upgrading our Sonic Mainnet infrastructure to v2.2.2. This is a stability release that addresses data races during shutdown and in the state database, reduces memory footprint, and improves signal handling during startup and password prompts. The release also enhances RPC API compatibility with Ethereum execution APIs. During the maintenance window, brief interruptions to RPC availability may occur. https://github.com/0xsoniclabs/sonic/releases/tag/v2.2.2

We are upgrading our Celestia Mainnet infrastructure to celestia-app v9.0.8. This release upgrades celestia-core to v0.40.9. During the maintenance window, brief interruptions to RPC availability may occur. RPC Changes: - BlockByHeight — Slow gRPC height subscribers may miss notifications; use BlockByHeight to backfill any gaps. https://github.com/celestiaorg/celestia-app/releases/tag/v9.0.8

We are upgrading our Gravity Mainnet infrastructure to v1.9.2. This release improves node sync consistency. During the maintenance window, brief interruptions to RPC availability may occur. https://github.com/Galxe/gravity-sdk/releases/tag/v1.9.2

We are upgrading our Polkadot Mainnet infrastructure to v1.24.2 (polkadot-stable2606-2). This 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 availability may occur. https://github.com/paritytech/polkadot-sdk/releases/tag/polkadot-stable2606-2

We are upgrading our Stacks Mainnet and Testnet API to v9.3.0. This release introduces a new staking cycle endpoint, removes obsolete microblock support, and includes several bug fixes for PoX cycle handling and post condition serialization. Brief interruptions to RPC availability may occur during the maintenance window. RPC Changes: - /extended/v3/staking/cycles/:cycle_number — New endpoint to retrieve staking summary data for a given PoX cycle number. - v3 transaction responses — post_condition_mode field is now correctly serialized in responses. - PoX cycle handling — Fixed treatment of STX lock rollovers under PoX-5 and corrected in-progress cycle staked STX calculation at cycle start. - Bond distribution events — Now include calculation_height and reward_cycle fields in responses. - URL parameter length — Router maximum URL parameter length has been increased to support longer query strings. - Microblock support — Microblock ingestion and unanchored data support have been completely removed; endpoints and methods relying on microblock data are no longer available. https://github.com/hirosystems/stacks-blockchain-api/releases/tag/v9.3.0

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. https://github.com/near/nearcore/releases/tag/2.14.0-rc.1

We are upgrading our Aptos Testnet infrastructure to aptos-node v1.49.1-rc. This is a hotfix release requested by the Aptos Foundation. Brief interruptions to REST API availability may occur on that date. https://github.com/aptos-labs/aptos-core/releases/tag/aptos-node-v1.49.1-hotfix-rc

We are upgrading our Fluent Testnet infrastructure to v1.5.0 (ALKAHEST) on 2026-09-17. This release focuses on runtime stability, EVM correctness, and performance improvements, including fixes for node crashes, bridge-related block failures, malformed-input handling, gas accounting, Solidity ABI compatibility, and contract routing. It also upgrades rWasm to version 0.6.0 and reduces execution overhead. Brief interruptions to RPC availability may occur on that date. https://github.com/fluentlabs-xyz/fluentbase/releases/tag/v1.5.0

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. https://github.com/xrplevm/node/releases/tag/v10.2.1

We are upgrading our Base Sepolia infrastructure to v1.4.0 ahead of the Cobalt hardfork, scheduled for September 23, 2026 at 18:00 UTC. During the maintenance window, brief interruptions to RPC availability may occur. RPC Changes: - Cobalt introduces validity transactions — signed transactions that only execute onchain when specified conditions (balance, storage, block number, or Flashblock index) are met, enabling conditional swaps, withdrawals, and other state-dependent actions via standard transaction submission. - Cobalt also brings improvements to the B20 token standard, including the ability to pay transaction fees in B20 tokens, scheduled multiplier updates, and new Union/Intersect policies. https://github.com/base/base/releases/tag/v1.4.0

We are upgrading our Fluent Mainnet infrastructure to v1.5.0 on 2026-09-21. This release improves runtime stability, EVM and SDK correctness, and performance with an upgrade to rWasm 0.6.0 (delivering approximately 5x execution performance improvement). The release also strengthens build provenance, publishing controls, and regression coverage. New VM opcodes will be activated on this date; RPC availability may be briefly interrupted. https://github.com/fluentlabs-xyz/fluentbase/releases/tag/v1.5.0
