Wallet development

Main responsibilities: 1. Responsible for the research and development of the arbitrage robot interaction end (non-contract), using nodejs and rust to develop the robot. Achievements: (1) Successfully arbitrage on multiple chains. (2) In the face of the pending message capture, the problem of not being able to capture all swap messages (third-party wallets or aggregators do not directly interact with the Router contract for swaps), the node debug function is used to capture the state of the message analysis, so that all transaction information and data for the swap of pairs can be captured. (3) Through revm, fork the current chain state, and directly simulate the transaction. The security status and tax rate of the contract can be quickly determined within 2ms. A large number of steps to interact with the chain and perform local calculations to obtain the results are reduced. And the results are accurate. (4) The designed algorithm can accurately find the optimal buying value that can withstand the slippage of the transaction without obtaining the token tax rate.
