Use a Solana deposit address when your sender can transfer USDC on Base and your recipient needs USDC on Solana. Your application requests and stores the address; Eco’s service monitors it and submits the intent-creation transactions. This recipe uses the static v1 deposit-address API. Read the availability and deprecation notes before starting a new integration.

​
Prerequisites

  • The recipient’s Solana wallet address
  • An EVM depositor address for the intent’s refund path
  • Base USDC and enough ETH for the sender’s transfer
  • A delivery check for the recipient’s Solana token account

​
Integrate the deposit flow

  1. Create a Solana deposit address using the recipient wallet and depositor. Store the returned evmDepositAddress, source chain, and factory address.
  2. Show the sender the returned address and identify Base USDC explicitly. This flow is not an address for arbitrary tokens or chains.
  3. Send USDC to that address on Base. The sender signs and pays gas for the ERC-20 transfer.
  4. Check processing and delivery. Contract deployment and the last observed balance show processing state, not destination delivery.
The configured factory, destination, and depositor determine the address. Preserve those inputs with the address; do not reuse an address for a different recipient.

​
Troubleshooting

  • If the source transaction failed, resolve the wallet or gas error before retrying.
  • If the transfer succeeded but delivery is delayed, keep its transaction hash and deposit record for investigation. Do not send another payment solely because the destination balance has not updated.
  • If the API reports an unconfigured chain, check the supported sources in the Solana guide.
