End User Accounts

Send USDC on EVM

Changed on Oct 6, 2026

Sends USDC from an end user's EVM account (EOA or Smart Account) to a recipient address on a supported EVM network. This endpoint simplifies USDC transfers by automatically handling contract resolution, decimal conversion, gas estimation, and transaction encoding. The amount field accepts human-readable amounts as decimal strings (e.g., "1.5", "25.50").

Request

Base URL: https://api.cdp.coinbase.com/platform
URL: https://api.cdp.coinbase.com/platform/v2/embedded-wallet-api/end-users/{userId}/evm/{address}/send/{asset}
Auth: one of:
- HTTP bearer
- HTTP bearer

Path parameters

userIdstring required

The ID of the end user.

addressstring required

A blockchain address. Format varies by network (e.g., 0x-prefixed for EVM, base58 for Solana).

Example:0x742d35Cc6634C0532925a3b844Bc454e4438f44e

The 0x-prefixed address of the EVM account (EOA or Smart Account) to send USDC from. The address does not need to be checksummed.

assetstring required

The symbol of the asset (e.g., eth, usd, usdc, usdt).

Example:usd

The asset to send. Currently only "usdc" is supported.

Query parameters

projectIDstring

Example:8e03978e-40d5-43e8-bc93-6894a57f9324

The ID of the CDP Project. Required for end users authenticated using custom auth (i.e. a non-CDP JWT provider).

Headers

X-Wallet-Authstring

A JWT signed using your Wallet Secret, encoded in base64. Refer to the Generate Wallet Token section of our Authentication docs for more details on how to generate your Wallet Token.

X-Idempotency-Keystring

An optional string request header for making requests safely retryable. When included, duplicate requests with the same key will return identical responses. Refer to our Idempotency docs for more information on using idempotency keys.

X-Developer-Authstring

A JWT signed using your Wallet Secret, encoded in base64. Refer to the Generate Wallet Token section of our Authentication docs for more details on how to generate your Wallet Token.

Request body

tostring required

A blockchain address. Format varies by network (e.g., 0x-prefixed for EVM, base58 for Solana).

amountstring required

The amount of USDC to send as a decimal string (e.g., "1.5" or "25.50").

The EVM network to send USDC on.

useCdpPaymasterboolean

Whether to use CDP Paymaster to sponsor gas fees. Only applicable for EVM Smart Accounts. When true, the transaction gas will be paid by the Paymaster, allowing users to send USDC without holding native gas tokens. Ignored for EOA accounts. Cannot be used together with paymasterUrl.

paymasterUrlstring uri

A valid HTTP or HTTPS URL.

paymasterContextPaymasterContext

The ERC-7677 context object forwarded to the paymaster service as part of the paymasterService capability. The fields in this object are defined by the paymaster service provider; CDP forwards them to the paymaster unchanged. This field is only valid when a paymaster is configured for the request. Providing paymasterContext without a paymaster configured results in an invalid_request error.

walletSecretIdstring

Required when not using delegated signing. The ID of the Temporary Wallet Secret that was used to sign the X-Wallet-Auth Header.

Example request

{
  "to": "0x742d35Cc6634C0532925a3b844Bc454e4438f44e",
  "amount": "1.50",
  "network": "base-sepolia",
  "useCdpPaymaster": true,
  "paymasterUrl": "https://example.com",
  "paymasterContext": {
    "policyId": "962b252c-a726-4a37-8d86-333ce0a07299"
  },
  "walletSecretId": "e051beeb-7163-4527-a5b6-35e301529ff2"
}

Response

Successfully sent transaction.

transactionHashstring nullable

The hash of the transaction, as a 0x-prefixed hex string. Populated for EOA accounts. Null for Smart Accounts (use userOpHash instead).

userOpHashstring nullable

The hash of the user operation, as a 0x-prefixed hex string. Populated for Smart Accounts. Null for EOA accounts (use transactionHash instead).

Example response

  "userOpHash": "0x1234567890abcdef1234567890abcdef1234567890abcdef1234567890abcdef"
