Get Receipt

Just like regular real-world transactions, when a transaction is processed on a blockchain network a receipt is generated. This receipt lists pieces of information that can be helpful in debugging contracts, as well as vital information such as a contract's block hash and contract address. The Maven CLI does not automatically retrieve the receipt after a transaction has been sent.

Return a transaction receipt: mvn aion4j:get-receipt

After you have deployed a contract, you can get the transaction receipt by running:

mvn aion4j:get-receipt -DtxHash=<TRANSACTION_HASH> -Dweb3rpc.url=http://<HOST>:<PORT> -Premote
Bash

For example:

mvn aion4j:get-receipt -DtxHash=0x6007cb6662418923ab966d443b23abb8e7a03043279d77e661f764bfc643ce83 -Dweb3rpc.url=http://138.91.123.106:8545 -Premote

This function returns a large amount of JSON data. The contract address of the contract you deployed is in the field contractAddress.

Automatic Responses

When requesting a transaction receipt, you can include -Dtail and -Dsilent to get back a cleaner response from the kernel.

Argument Description
-Dtail Keep requesting the receipt every 10 seconds until it is received.
-Dsilent Removes unimportant logs.

For example:

mvn aion4j:get-receipt -DtxHash=0x014aa6362f512079163d15c4e7e6111244c48b060f0d3e3ee7140036f136cf6a -Dweb3rpc.url=https://api.nodesmith.io/v1/aion/avmtestnet/jsonrpc?apiKey=12343567890abcdef...  -Dtail -Dsilent -Premote
