This guide will walk you through the process of sending ETH from your non-custodial Smart Wallet using the Crossmint transactions API. One of the benefits of non-custodial Smart Wallets is that you can hold and send different cryptocurrencies.

​
Prerequisites

Check out our Quickstart for non-custodial Smart Wallets to prepare the following:

  • API Key: Ensure you have your Crossmint API key with the scope wallets:transactions.create.
  • Wallet Locator: The locator of the wallet you want to transfer the tokens from.

​
Sending the transaction

We provide a Create Transaction API for your created Smart Wallet. To send ETH, we need to set the following parameters:

  • calls: An array of objects with the following properties:
    • to: The recipient’s Ethereum address.
    • value: The amount of ETH to send, in wei.
    • data: Unnecessary for just sending ETH. Set it to "0x".
  • chain: The chain where the transaction will be sent.
  • signer: One of the wallet’s signers. In most cases, this will be the admin signer.
