CACAOs is a Rust library implementing the CAIP-74 Chain-Agnostic Object Capability Specification, with built in support for Sign In With Ethereum.
A simple example using SIWE-type CACAOs:
use async_trait::async_trait;
use cacaos::{
siwe_cacao::{Eip191, Eip4361, Payload, SiweCacao},
SignatureScheme,
};
use futures::executor::block_on;
use hex::FromHex;
use libipld::{cbor::DagCborCodec, codec::Encode, multihash::Code, store::DefaultParams, Block};
use siwe::Message;
use std::str::FromStr;
async fn run_example() {
let message: Payload = Message::from_str(
r#"localhost:4361 wants you to sign in with your Ethereum account:
