MetaTrust Labs recently completed the formal verification of the main part of the Uniswap V3 Swap protocol at the invitation of Xcalibyte. This verification rigorously analyzed the source code of Uniswap and mathematically proved that it correctly implements the expected financial model described in the Uniswap V3 white paper.
To verify the complex code and model of Uniswap, MetaTrust Labs utilized its self-developed innovative analysis tools. Below is the process the team followed for the verification.
As part of our research on Web 3.0 security, we conducted formal verification of most of Uniswap V3.
We first constructed a formal model of the Uniswap V3 source code using the specification language supported by our verification tools. Secondly, we provided the properties that must be satisfied for the Uniswap formal model using the logic defined by our tools, which is a formal reduction description. These properties formalize the financial model described in the Uniswap V3 white paper, involving complex mathematical concepts such as discrete integrals.
Due to the complexity of the financial model of Uniswap V3, standard verification tools were unable to prove that the Uniswap code correctly represents its mathematical model. Our tools employ cutting-edge verification techniques to describe and verify such complex systems.
Technically, the tool implements automated verification using higher-order separation logic combined with data refinement, and is formally defined and implemented in the Isabelle/HOL theorem prover.
Compared to existing methods, first, formal verification based on theorem provers has the most reliable trust foundation due to its formally defined semantics and reasoning system. Secondly, a reasoning system built on a higher-order separation logic with effective expressiveness allows us to express and verify high-level reductions of financial models, such as the discrete integrals described in the Uniswap V3 white paper, which traditional verification tools like Solidity's built-in SMT verifier cannot achieve.
This success highlights the value of customized verification tools in auditing complex DeFi systems. Mathematically grounded verification makes the next generation of trusted and widely used DApps possible.
David from MetaTrust Labs also stated, "We are proud to provide the analytical capabilities that played a key role in this significant achievement. This level of formal verification sets a new standard for the transparency and reliability of blockchain software."
The formal verification of the Uniswap V3 Swap protocol by MetaTrust Labs is a breakthrough for the DeFi ecosystem and gives Uniswap users more reasons to trust and use its platform.
