What is Automated Market Maker(AMM)In a decentralized world, people need to swap tokens. However, money does not exist at first and nobody behaves as a market maker. Where does the money come from? People put tokens into a liquidity pool to that others could swap tokens they supplied. They are called liquidity providers. Who is the market maker? Code. The immutable smart contract permanently stored on the blockchain does the job. The contract determines the exchange rate of a token pair. The ...

TLDRIn the contract, Eva can reuse a valid signature of Alice’s because the verification doesn’t involve the transaction sender’s address, nonce or anything particular to a user and a transaction.Contract AnalysisMintThe whitelist users are supposed to call the mint_approved function to mint the NFT.This function accepts three parameters:info, a struct contains an address from and the signature to verify. struct vData { bool mint_free; uint256 max_mint; address from; uint256 start; uint256 en...
