Lien Protocol’s Smart Contract Audits: Provided By CertiK

What is Lien?

iDOL is a stablecoin backed by Ethereum derivatives known as SBT, Solid Bond Tokens. Unlike other crypto-collateralized stablecoins, Lien requires no over collateralization or manual adjustments of parameters to maintain the exchange rate.

CertiK was proud to work with Lien to review issues and vulnerabilities in the source code of Lien Protocols Contracts.

Audit Scope and Details

  1. iDOL
  2. Fairswap
  3. Lien Token
  4. Oracle

Each module is utilized to form the iDOL stablecoin as well as provide a way to hold Vickrey auctions for Ether.

Procedural Steps During the Audit

During the second phase of the two-week process, CertiK analyzed the source code of the core protocol within iDOL and delved into greater depth on the Fairswap repository to identify any potential vulnerabilities, misalignments with the specifications, and unaccounted for functionalities and/or behaviors.

All findings are split into four categories:

  1. Informational
  2. Minor:
  3. Medium
  4. Major

Results and Conclusions from the Audit

“We maintained a direct real-time communication channel with the Lien team to ease the process of evaluating the remediations as well as go through multiple revisions of a change when necessary. The Lien team was highly responsive and provided code changes for the remediations in a very timely manner,” stated by CertiK’s Engineers.

Overall, the Lien team demonstrated an in-depth understanding of the mathematical formulas involved in the solution they aspire to launch and showcased a healthy code ethics within each project’s codebase.
