Authorizations

​
Authorization
string
header
required

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

Headers

​
X-Request-Id
string<uuid>

Developer-provided identifier for this request, used for tracing requests in Wallets API logs and the Developer Console, and when communicating with Circle Support. Must be a UUID to appear in logs. Non-UUID values are accepted by the API but are ignored by logging and tracing systems.

A unique identifier, which can be helpful for identifying a request when communicating with Circle support.

Example:

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

Body

application/json

Schema for the request payload to sign a transaction.

​
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:

"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"

​
walletId
string<uuid>

System-generated unique identifier of the resource.

Example:

​
rawTransaction
string

Raw transaction string that needs to be signed. Excluded with transaction. Required without transaction. Required to be base64 encoded for NEAR, Solana chains. Required to be hex encoded for EVM chains.

Example:

"AgAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAgAIAAQROrEbiYfF3zCII9..."

​
transaction
string

Transaction object in JSON that needs to be signed. Excluded with rawTransaction. Required without rawTransaction.

NOTE: This field is only supported by EVM chains.

Example:

"{\"nonce\":1,\"to\":\"0x9e4ebf23f713268b8e72cd162337f20c536357c9\",\"value\":\"10000000000000000\",\"gas\":\"21000\",\"maxFeePerGas\":\"42000000000\",\"maxPriorityFeePerGas\":\"25000000000\",\"chainId\":80002}"

​
memo
string

The human readable explanation for this sign action. Useful for presenting with extra information.

Example:

"Transfer USDC to Sam"

​
blockchain
enum<string>
