We are upgrading our Morph Mainnet infrastructure to node v0.6.4 and morph-v2.2.7 ahead of the mandatory Celadon network upgrade, which activates on Hoodi Testnet at 2026-10-28 06:00 UTC.
Celadon introduces MorphTx v2, which lets users pay gas with an alternative token and delegate their EOA to contract code (EIP-7702) in a single transaction. It also corrects the rounding of alt-token fee refunds, so users are charged the precisely rounded net fee. All existing transaction types, including MorphTx v0/v1 and standard 0x04 SetCode transactions, remain fully supported.
During the maintenance window, brief interruptions to RPC availability may occur.
RPC changes: - eth_sendRawTransaction — MorphTx v2 (type 0x7F, version 0x02) is accepted once Celadon activates. Before activation, v2 transactions are rejected. - Transaction-building requests (e.g. eth_sendTransaction, eth_estimateGas) — The MorphTx version no longer needs to be specified and is derived from the request. A non-empty authorizationList combined with feeTokenID, reference, or memo builds a v2 transaction. Otherwise, v1 is used. - eth_getTransactionByHash — Now returns authorizationList for MorphTx v2 transactions. - MorphTx v2 transactions with a non-empty authorizationList cannot create contracts (same rule as EIP-7702). - Fees for transactions paying gas in an alternative token may differ slightly from previous values due to the corrected refund rounding.
