Stablecoin smart contract audit

Softstack audited the smart contracts for a stablecoin protocol built on Canton Network, focusing on collateral handling, minting/redemption flows, and access controls. We found several critical vulnerabilities in the stability mechanisms and worked with the team to fix them. After the patches were implemented, we ran a follow-up audit to confirm everything was secure before they went live.

Softstack Provided Outstanding Web3 Security Audit Expertise

Softstack performed a thorough smart contract audit for our cross-chain stablecoin infrastructure, encompassing privacy-enabled settlement layers, yield-bearing vaults, oracle-secured bridges, and multi-chain mechanisms. Their auditors uncovered and resolved key vulnerabilities like replay risks and economic exploits with precise, actionable recommendations, ensuring robust mainnet deployment. Exceptional professionalism, timely delivery, and deep blockchain knowledge. Strongly recommended for serious stablecoin projects.
