Ethereum: How to Get a Wallet Address and Set a Label via RPC
As an Ethereum developer or user, you’re probably familiar with the basic RPC commands used to interact with the Ethereum network. However, getting a wallet address and setting a label can be a bit more complex than standard transactions. In this article, we’ll explore how to accomplish these tasks using pure RPC calls.
Get a Wallet Address
The easiest way to get a wallet address is to create a new wallet and then retrieve the address. Here’s an example RPC call that accomplishes this:
RPC call: eth wallets.getWalletsByHeight(height)
This command retrieves a list of all active Ethereum wallets. The getWalletsByHeight() method returns a list of objects, each of which represents a wallet, including its address.
Assuming you have created an Ethereum wallet on your local computer (e.g. using the eth-wallet tool), you can use RPC to get the address associated with that wallet:
RPC call: eth wallets.addressOfWallet(height)
This command retrieves the hexadecimal address associated with the specified wallet value.
Setting a label
A label is an optional field in the Ethereum wallet object that allows users to identify their wallet by name or other criteria. To set a label, you need to use the RPC call “eth wallet.setLabel()”:
RPC call: eth wallets.setLabel(walletAddress, "Name of my wallet")
This command sets the label for the specified wallet address.
To get the current wallet labels, you can use the following RPC call:
RPC call: eth wallets.getWalletLabels(walletAddress)
The getWalletLabels() method returns a list of objects, each of which represents a wallet label. You can then iterate through these labels to find the one associated with your wallet.
Example Use Cases
Here are some example use cases for retrieving a wallet address and setting a label via RPC:
- Retrieving the address of an existing wallet:
RPC call: eth wallets.addressOfWallet(height)
- Setting a new label for a wallet:
RPC call: eth wallets.setLabel(walletAddress, "My new wallet name")
Note
: The Ethereum blockchain is constantly changing and the available RPC commands may vary depending on your Ethereum network version (e.g. mainnet, testnet).
By using these RPC calls, you will be able to get and set wallet addresses and labels in a purely RPC-based environment. Have fun coding!
