We performed a security audit of the zkBTC Circuit Implementation and Smart Contracts. zkBTC Bridge is a native zero‐knowledge proof-based cross‐chain protocol by Lightec that enables Bitcoin holders to convert BTC into an ERC-20 token, $zkBTC, on Ethereum at a 1:1 peg. Our final audit report was completed on June
Lightec requested that Least Authority review several components of the zkBTC protocol, which is a bridge between Bitcoin and Ethereum, using techniques from zero-knowledge proofs. The bridge allows a Bitcoin user to mint a zkBTC token, use this token in the Ethereum ecosystem, and eventually redeem the Bitcoin from the
We performed a security audit of Gnosis Hashi — an Ethereum Virtual Machine (EVM) Hash Oracle Aggregator that utilizes third-party hash oracles to aggregate hashed data, such as block headers or other arbitrary messages, in order to facilitate secure cross-chain communication. We completed our final audit on July 18, 2024.
Least Authority performed research, investigation, and review of the Ava Labs Bridge Smart Contracts followed by issue reporting, along with mitigation and remediation instructions as outlined in this report. To read the full report, including our findings, click here: Report
Althea has requested that Least Authority perform a security audit of their Gravity Bridge, a bridge between Ethereum and Cosmos-based blockchains. The Gravity Bridge facilitates the transfer of ERC-20 tokens originating on Ethereum to Cosmos and back to Ethereum. Report
