Ƭ AccessedStateWithAddress: AccessedState & { address: Address ; chunkKey: PrefixedHexString }

Variables

BALANCE_LEAF_KEY

• Const BALANCE_LEAF_KEY: Uint8Array

Defined in

accessWitness.ts:14

---

CODEHASH_PREFIX

• Const CODEHASH_PREFIX: Uint8Array

Prefix to distinguish between a contract deployed with code 0x80 and RLP([]) (also having the value 0x80).

Otherwise the creation of the code hash for the 0x80 contract will be the same as the hash of the empty trie which leads to misbehaviour in the underlying trie library.

Defined in

Defined in
