We are upgrading our Avalanche Fuji Testnet infrastructure to v1.15.0-fuji ("Helicon") ahead of a coordinated network upgrade activating at 11 AM ET (3 PM UTC) on Tuesday, July 28th, 2026.
This release schedules the activation of several Avalanche Community Proposals (ACPs), including C-Chain async execution, auto-renewed staking, increased validator uptime requirements, reduced minimum validator staking duration, dynamic minimum C-Chain gas price, and a reduced minimum consumption rate.
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.
