Returns an EIP-2930 access list that you can include in a transaction. You can use this method to optimize your smart contract interactions. This method will use 20 Compute Units.
Unichain Mainnet keeps historical state for roughly the last 10,000 blocks, about 2.8 hours at Unichain’s 1-second block time. Requests for an older block return JSON-RPC error -32603 with a message that contains state at block #<number> is pruned.
