CertiK Security Audit Report

CertiK was engaged to perform a comprehensive security assessment of USDC Bridged Solana (USDC.c), a bridged stablecoin deployed on the Solana mainnet.

The audit focused on the project’s smart contract implementation, reserve transparency, and overall ecosystem security posture. Our team conducted a combination of static analysis, manual review, on-chain verification, and reserve validation to ensure compliance with Solana SPL Token standards and best practices in decentralized finance.

Key Findings:

  • ✅ No critical vulnerabilities identified.
  • ✅ Token adheres fully to SPL Token Program design.
  • ✅ Transparent multi-wallet reserve structure.
  • ⚠️ Minor advisory on reserve governance centralization.

Overall, USDC.c is assessed as Low Risk and recommended for deployment in production environments.

Medium Risk – Reserve Governance

  • Description: While reserves are held in multiple wallets, they are managed by centralized custodians. Governance policies for withdrawals and attestations are not fully decentralized.
  • Recommendation: Introduce multi-signature wallets and publish monthly Proof-of-Reserve attestations from an independent auditor.

Minor Risks

  1. Event Logging – Recommend more robust event tracking for supply changes.
  2. Documentation Gap – Technical documentation should clearly state upgrade policies.

Informational Notes

  • Adoption across Solana DEXs is strong, but broader interoperability (e.g., with EVM bridges) is in progress.
  • Oracle feeds (Pyth, Switchboard) may be considered for future price-proof enhancements.
  • Community governance could improve transparency and decentralization narrative.

Conclusion

The USDC Bridged Solana (USDC.c) token is secure, functional, and production-ready. The audit did not identify any critical or major vulnerabilities. While some centralization risks exist in reserve governance, these are mitigated by transparency, multi-wallet distribution, and potential for future third-party attestations.

USDC.c is recommended for public launch and assessed as Low Risk.
