wholesale crystal charms for making jewelry If you want to check the transaction records on the main network, you can use Etherscan. However, if you are a private chain you set up, how should you check the transaction record?
The answer is that you need to monitor the logs on your own, save it in the database, and check in this database. For example:
12345678varaddr = "" varfilter = web3.eth.filter ({fromBlock: 0, TOBLOCK: Latest, address: addr}); vartxinfo = web3.eth. (tx.); // At this time, you can store the transaction information txinfo into the database});}); It is used to extract the designated transaction. Once the transaction information is obtained, you can store it in the database for inquiry.
