Library for encoding and signing EIP-712 typed data in elixir.
See the documentation for more information.
The package can be installed by adding eip712 to your list of dependencies in mix.exs:
def deps do
[
{:eip712, "~> 0.2.0"}
]
endpriv_key = EIP712.Util.decode_hex!("0xac0974bec39a17e36ba4a6b4d238ff944bacb478cbed5efcae784d7bf4f2ff80")
%EIP712.Typed{
domain: %EIP712.Typed.Domain{
chain_id: 1,
name: "Test",
verifying_contract: EIP712.Util.decode_hex!("0xCcCCccccCCCCcCCCCCCcCcCccCcCCCcCcccccccC"),
version: "1"
},
types: %{
"Test" => %EIP712.Typed.Type{fields: [{"items", {:array, :string}}]}
},
value: %{
"items" => ["item1", "item2"]
}
}
|> EIP712.sign!(priv_key, hex?: true)
# => "0x97ce47cfb1497f72019606ba462c3ab4e3552c4225f3b7b75ca42c5787a19b7c29d53b9fe402102a82ea782e806224f819b326b74f98049fe59486640d6fa2911c"MIT
This library consists of the EIP-712 pieces extracted from Signet. Thanks to Geoff Hayes for the original implementation.
