Transactions

Transfer tokens

This operation initiates a token transfer from the specified wallet.

You need to provide dst_addr, amount, and token_id. The chain_id is automatically resolved from token_id.

Supply request_id to enable idempotency. If a transfer with the same request_id already exists for the same principal, the existing record is returned with idempotent=true.

The operation returns status=200 (PENDING_APPROVAL) when an approval policy requires review before execution. Use the pending_operation_id in the response to track and resolve the approval.

Policy evaluation runs before submission. The operation returns an error if a policy denies the transfer.

Headers

X-API-Key

string | null

Path Parameters

wallet_uuid

string<uuid>

required

The UUID of the wallet to transfer tokens from. Retrieve this value from the id field returned when the wallet was created.

Body

application/json

Request payload for token transfer.

dst_addr

string

required

The destination on-chain address.

Required string length: 1 - 255

amount

string

required

The transfer amount as a decimal string (for example, 1.5).

Required string length: 1 - 100

token_id

string

default:SETH

The Cobo token ID to transfer (for example, SETH, SETH_USDC, SOLDEV_SOL_USDC). Use the List supported assets operation to retrieve all supported token IDs. Defaults to SETH.

Required string length: 1 - 100

chain_id

string | null

The chain ID. Automatically resolved from token_id if omitted.

Maximum string length: 100

request_id

string | null

A client-supplied identifier for idempotency. If a transfer with the same request_id already exists for the same principal, the existing record is returned.

Maximum string length: 255

fee

EIP1559FeeRequest · object

Optional custom fee parameters. If omitted, the network default is used.

EIP1559FeeRequest
EVMLegacyFeeRequest
SOLFeeRequest

src_addr

string | null

The source address to transfer from. If omitted, the server auto-selects the wallet address on this chain with the highest available token_id balance (explicit src_addr always takes precedence).

Maximum string length: 255

Whether to use Cobo Gasless (Fee Station) to cover gas fees. true: gas fees are sponsored. false: gas fees are paid from the wallet. Defaults to true for human-owned wallets, false for agent-owned wallets.

gas_provider
