It is a great tool, somehow the last step "swap dust" failed with error, tried both MetaMask and Rabby Wallet in Chrome.
Error: unknown account #0 (operation="getAddress", code=UNSUPPORTED_OPERATION, version=providers/5.7.2)
COCA wallet looks very promising, well done.
Just a couple of questions.
1. Is the underlying MPC protocol a n of m scheme, or fully decentralized?
2. Is the work open source?
