With 3MI Labs, we audited the Rust implementation of dWallet Labs’ 2PC-MPC protocol.
The review compared the implementation with the protocol paper and examined its supporting cryptographic crates. The report records three main security findings, including critical nonce reuse in the decentralized-party presigning step. It also recommends further work on protocol analysis, state transitions, performance, and integration.
The assessment was conducted with Erik Takke and Tomer Ashur of 3MI Labs. We also thank Yehonathan Cohen Scaly and Dolev Mutzari of dWallet Labs for their technical input.
