Summary

Functions

Deserializes a domain from JSON or JavaScript encoding to a struct.

Serializes a domain, such that it can be JSON-encoded or passed to JavaScript.

Serializes a domain's keys to be JSON-compatible. This is so that it can be used as a value for hashStruct, per the EIP-712 spec to build a domain specifier.

Types

@type t() :: %Signet.Typed.Domain{
  chain_id: number(),
  name: String.t(),
  verifying_contract: <<_::160>>,
  version: String.t()
}
