This guide features Developer-Controlled Wallets. Circle Wallets also supports User-Controlled Wallets. Check out the User-Controlled Wallets quickstart.
Circle Wallets provide a comprehensive developer solution to storing, sending, and spending Web3 digital currencies and NFTs. You or your users can manage asset infrastructure. Circle provides a one-stop-shop experience with all the tools and services to handle the complex parts, including security, transaction monitoring, account recovery flows, and more.
This guide will assist you in creating a developer-controlled wallet. You will learn how to create a wallet set, and ultimately establish a wallet. Throughout this comprehensive guide, you will utilize both command line and API requests. These can be achieved by referring to Circle's API references or utilizing cURL requests. For how to navigate the API references, see the Testing API References guide.
You can create wallets for both Smart Contract Accounts (SCA) and Externally Owned Accounts (EOA). To learn more, see the Account Types guide.

A wallet set refers to a unified set of wallets, all managed by a single cryptographic private key. This makes it possible to have wallets from different blockchains sharing the same address.
To create a wallet set, make a request to
POST /developer/walletSets
and create a wallet set providing a unique Entity Secret Ciphertext as described
in
How to Re-Encrypt the Entity Secret.
const response = await circleDeveloperSdk.createWalletSet({
name: 'Entity WalletSet A',
})
{
"data": {
"walletSet": {
"id": "0189bc61-7fe4-70f3-8a1b-0d14426397cb",
"custodyType": "DEVELOPER",
"updateDate": "2023-08-03T17:10:51Z",
"createDate": "2023-08-03T17:10:51Z"
}
}
}
In Web3, a wallet isn't just a storage mechanism for digital tokens or NFTs; it’s the core structure of all user interactions on the blockchain. A wallet is comprised of a unique address and accompanying metadata stored on the blockchain.
To create a wallet, make a POST
request to
/developer/wallets
using the walletSet.id
from step 2 and a count
of 2
as request parameters.
We'll use the second wallet in the following quickstart to transfer tokens from
wallet to wallet. NOTE: Don't forget to generate a new Entity Secret
Ciphertext.
The following code samples show how to create an SCA wallet on Amoy and the response.
