I am experienced with Ethereum development. I have built multiple smart contracts and dapps which interacts with those smart contracts. Relevant Skills and Experience Ethereum, Blockchain, Smart Contract, Solidity Proposed Milestones $555 USD - Final Delivery I think for this particular task we don't need to run our own node, instead we can use apis provided by the etherscan to record the transaction for a contract address. This will allow us to save aws resource in terms of computing power, storage cost and bandwith usage.
