Solution

There are 4 repos:Contract (Solidity): Using Solidity to complete whole lending protocol.Circuits (Circom): Using Circom to develop the on-chain verify method.Merkle-Tree (Typescript): Sparse Merkle Tree (SMT) method.Front-end (WAGMI): Use NextJS and WAGMI.Sponsor Tech:Polygon ID backend circuitsHardhat deployed EVM-Compatible ChainZK-EVMs Deployed and testedWe deployed the contract to mentle, scroll, polygon mumbai, gnosis, celo, taikko. Therefore we can use this certification to borrow money on anychain.We also publish a SMT in npm. Link: https://www.npmjs.com/package/zkafi-merkle-tree
