Expand description

Trait that provides necessary data when forking a remote chain. The method signatures are similar to methods from ETHNamespace and ZKNamespace.

Required Methods§

source

Returns the Storage value at a given index for given address.

source

fn get_bytecode_by_hash(&self, hash: H256) -> Result<Option<Vec<u8>>>

Returns the bytecode stored under this hash (if available).

source

fn get_transaction_by_hash(&self, hash: H256) -> Result<Option<Transaction>>

Returns the transaction for a given hash.
