Basic commands
Here are some basic commands you can use with the curl eth interface:
| Command | Description |
|---|---|
| curl eth nodeinfo | Displays information about the Ethereum node you are connected to. |
| curl eth accounts | Lists all accounts on the Ethereum node. |
| curl eth blockNumber | Displays the current block number of the Ethereum network. |
Interacting with smart contracts
One of the most powerful features of the curl eth interface is the ability to interact with smart contracts. Here’s how you can do it:
1. Find the address of the smart contract you want to interact with.
2. Use the curl eth call command to interact with the smart contract. For example:
curl eth call --to --data--value
Replace
with the smart contract address,Monitoring transactions
