func LatestSigner(config *params.ChainConfig) Signer

LatestSigner returns the 'most permissive' Signer available for the given chain configuration. Specifically, this enables support of EIP-155 replay protection and EIP-2930 access list transactions when their respective forks are scheduled to occur at any block number in the chain config.

Use this in transaction-handling code where the current block number is unknown. If you have the current block number available, use MakeSigner instead.

func LatestSignerForChainID added in v1.10.0 

func LatestSignerForChainID(chainID *big.Int) Signer

LatestSignerForChainID returns the 'most permissive' Signer available. Specifically, this enables support for EIP-155 replay protection and all implemented EIP-2718 transaction types if chainID is non-nil.

Use this in transaction-handling code where the current block number and fork configuration are unknown. If you have a ChainConfig, use LatestSigner instead. If you have a ChainConfig and know the current block number, use MakeSigner instead.
