DFI and DMX are both forks of PieDAO, which is a cutting-edge, open-source protocol for creating indices. PieDAO has undergone several audits, which returned no major risks or issues.
DFI and DMX have both also undergone a separate audit by Chainsulting, a smart contract audit firm that has been around since 2017. The audits found no critical bugs or issues. The complete audit report and certificate of compliance for both token smart contracts can be found below.

PECO, which leverages the same Ecosystem Index smart contracts in DFI, was similarly audited by Chainsulting

We also hosted a code4rena contest to further test our smart contract security for PECO.
SOLI was audited by Certik. We built it leveraging a similar methodology strategy as our other Ecosystem Index tokens, however the smart contract implementation is quite different given Solana's development environment.
