Ethereum Monitoring Service
A small service to monitor and track confirmations on-chain. This tracks by creating a table of mined blocks, to avoid chain reorganization we wait for 6 transaction confirmations to consider the data is finalized. The data can then added be added to off-chain db for performacne at scale. This example monitors transactions to the WETH address 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2.
