Bonfire Wallet is a passwordless burner wallet that leverages WebAuthn to onboard the next 1 million crypto users, with biometrics or a token for authentication, making it accesible to anyone entering the crypto ecosystem. Using RISC-Zero, heavy verification computation can be offloaded through verifiable computation.
For this project, it is necessary to run a local relayer for RISC-Zero as described here (step 1, 2, 3). This was added to this codebase for completeness.
Make sure to clear the cache of MetaMask in between.
anvil
cd my-project
RELAY_PRIVATE_KEY=0xac0974bec39a17e36ba4a6b4d238ff944bacb478cbed5efcae784d7bf4f2ff80 forge script script/Deploy.s.sol:Deploy --rpc-url http://localhost:8545 --broadcast
cargo run relay --relay-contract-address 0x5fbdb2315678afecb367f032d93f642f64180aa3 --eth-node-url ws://localhost:8545 --private-key ac0974bec39a17e36ba4a6b4d238ff944bacb478cbed5efcae784d7bf4f2ff80
This does not "finish"; it runs until you stop it or the anvil instance is stopped.
When interaction also with MetaMask, make sure to clean the cache in between to ensure a clean slate.
This wallet can be run in a browser with MetaMask. All previous steps must have been completed before running
Example code: https://github.com/MasterKale/SimpleWebAuthn/tree/master/example
This server code expects the frontend to run on port 3000. If this is not the case, change the hardcoded expectedOrigin in server/src/index.ts.
npm install
npm start
The WebAuthn server must be running on 127.0.0.1:8000, if it is somewhere else, this has to be adjusted in frontend/package.json, specifically "proxy": "http://127.0.0.1:8000".
Open the console in the Developer Tools to see additional messages.
