We are upgrading our NEAR Mainnet infrastructure to nearcore 2.14.0 on 2026-10-30. This is a mandatory protocol upgrade (protocol version 86 to 88) introducing consensus-breaking changes, new action validation rules, and improved cryptographic support. Validators must upgrade before protocol version 87 voting begins on November 4th. Brief interruptions to RPC availability may occur on that date.
RPC Changes: - view_access_key_list now supports pagination with after_key and limit parameters, returning a last_key field. Accounts with more than 100 access keys must use pagination; unpaginated requests for these accounts will fail. - tx, send_tx, and broadcast_tx_commit responses now include an optional cause field on TIMEOUT_ERROR, describing transaction progress (NOT_OBSERVED, PENDING, DOES_NOT_TRACK_SHARD, or ERROR). - tx_status is now the stable method name for what was EXPERIMENTAL_tx_status. Both names work identically; Quicknode documentation for tx_status is in progress.
