Authorizations

​
Authorization
string
header
required

Circle's API Keys are formatted in the following structure "PREFIX:ID:SECRET". All three parts are requred to make a successful request.

Headers

​
X-Request-Id
string

Developer-provided parameter used to identify this request. Useful when communicating with Circle Support.

Example:

"2adba88e-9d63-44bc-b975-9b6ae3440dde"

Body

application/json

Schema for the request payload to create a new wallet.

​
idempotencyKey
string<uuid>
required

Universally unique identifier (UUID v4) idempotency key. This key is utilized to ensure exactly-once execution of mutating requests. To create a UUIDv4 go to uuidgenerator.net. If the same key is reused, it will be treated as the same request and the original response will be returned.

Example:

"a0eebc99-9c0b-4ef8-bb6d-6bb9bd380a11"

​
blockchains
enum<string>[]
required

Blockchain(s) the requested wallets will be created on.

​
entitySecretCiphertext
string<byte>
required

A base64 string expression of the entity secret ciphertext. The entity secret should be encrypted by the entity public key. Circle mandates that the entity secret ciphertext is unique for each API request.

Example:

"M8OAwbJ8rMsPd8+NT4xRDBDJSNqUKAvJeWPyuwZSlVXgRucogAlBxjvjIw4nsKeJ4hejjlpmyaaJrusHm6zsvy4BLuL1an3dYn3wORjYf3sU4QN9Rdk9OJxZvE5hDNPq7okucvb1eElxPVREZvr4ew7sh4ktmwDrwWFUYwKoly4fEzxYI9zvVpCY9xPSgkA5m3u1/P2vMYZ0QFtn8lRZxCuTyc4wRLpT9TOaK46CEXCakmAYaYWnLkl18QXOSY6FhCbGm+zQ2Uu4cUPU/bqjIyQIB80ut3drInDzysQLE/FJjcJW9+q+E75LKGKnrp2zCg/Xv3TEvru9a2A0vd7InZ9kNuxnPPFc1JSO7BT2TPP89YcLO0OmtRiGoXPlYzXuNIfUsVQ5/FW9FPp4qp+iMPrAidsjQrskHPxhW92GeezLpOSkUl7lAWQoioYED979mqGfzNIZTF5Ob6fJifboiwhOab6sAKnxmvWjgFnW/bZ5a8xkzgPc4RHpIejot1Q7fpT+67eA+DVxvUqakJI6t3iEaZTNITCSU2Cfj1oyCQfrZGf9tauW49rO1zYHKoV4z9ylymOWtCUk641iyxwFCNSW47CDsc0M8iI4J6JqsNMpQuR9sdWVhROi5yn9UR7ac7pizB3dFmc0/qjtTRoYStaaSEYg3L5woALv5kAA2j4="

​
walletSetId
string<uuid>
required

System-generated unique identifier of the resource.

Example:

"c4d1da72-111e-4d52-bdbf-2e74a2d803d5"

​
accountType
enum<string>

An account can be a Smart Contract Account (SCA) or an Externally Owned Account (EOA). To learn more, see the account types guide.

If an account type is not specified during the creation of a wallet, it defaults to EOA (Externally Owned Account). Note that Solana and Aptos don't support Smart Contract Account (SCA).

Available options:
SCA,
EOA
​
count
integer

Number of wallets that will be created per specified blockchain.

Required range: 1 <= x <= 200
Example:

2

​
metadata
object[]

List of metadata fields to associate with the corresponding wallet. If count is specified, the amount of items in the array should match the count field.

Response

Returns the existing wallet(s) if the idempotency key matches a previous successful request.
