EIP-1186 account proof. Quantities are integers; addresses, hashes and RLP proof nodes are raw bytes. Storage keys are integers, accepting either padded DATA or QUANTITY encodings from clients. Proofs are not verified locally.

Summary

Types

raw()

An eth_getProof result as the node returns it: hex strings under "address", "balance", "nonce", "codeHash", "storageHash", a hex list under "accountProof", and "storageProof" entries.

raw_storage()

One storageProof entry: hex "key" and "value", hex list "proof".

t()

Functions

deserialize(params)

Decodes all required EIP-1186 fields, raising on missing or malformed data.

Types

raw()

@type raw() :: %{required(String.t()) => String.t() | [String.t()] | [raw_storage()]}

An eth_getProof result as the node returns it: hex strings under "address", "balance", "nonce", "codeHash", "storageHash", a hex list under "accountProof", and "storageProof" entries.

raw_storage()

@type raw_storage() :: %{required(String.t()) => String.t() | [String.t()]}

One storageProof entry: hex "key" and "value", hex list "proof".

t()
