Reduce repetitive configuration work. u  Use geth and blockscout to build a test network environment for the company, so as to obtain unlimited test coins and debug the query contract to report errors. u  Standard design and writing of readme.md document. l  The implementation of erc20 is implemented by using the erc20 contract of openzeppelin agent contract upgrade, and secondary development is carried out. l  The charging and withdrawing system uses smart contracts to process the withdrawal business in batches, which saves 50% of the gas cost for large-scale withdrawal operations. For large cash withdrawals, join the audit mechanism, use the erc712 signature protocol, and apply a unified management framework to enable the monitoring system to take actions quickly when detecting abnormalities. l  The implementation of erc721 is implemented by using the updated version of erc721 contract of openzeppelin agent contract, and secondary development is carried out.
