🍷 Elixir

The Elixir implementation of Sign in with Ethereum can be found here:

signinwithethereum/siwe-ex

→

Installation

Add the library to your mix.exs dependencies:

def deps do
  [
    {:siwe, "~> 0.3"}
  ]
end

Example Usage

To test the library, clone the repository and run:

$ mix deps.get

Create two files:

message.txt:

login.xyz wants you to sign in with your Ethereum account:
0xfA151B5453CE69ABf60f0dbdE71F6C9C5868800E

Sign in with Ethereum Example Statement

URI: https://login.xyz
Version: 1
Chain ID: 1
Nonce: ToTaLLyRanDOM
Issued At: 2021-12-17T00:38:39.834Z

signature.txt:

0x8d1327a1abbdf172875e5be41706c50fc3bede8af363b67aefbb543d6d082fb76a22057d7cb6d668ceba883f7d70ab7f1dc015b76b51d226af9d610fa20360ad1c

Then in iex:

iex> {:ok, msg} = File.read("./message.txt")
iex> {:ok, sig} = File.read("./signature.txt")
iex> Siwe.parse_if_valid(String.trim(msg), String.trim(sig))

This will return a parsed SIWE message with details like address, chain ID, domain, and other metadata.
