# Stablecoin transfer

> How to transfer assets from a Byzantine account to any wallet.

## Transferring out of a Byzantine account

A transfer moves stablecoins directly from the user's secure Byzantine account wallet to **any destination wallet address** on-chain. Unlike a withdrawal — which off-ramps funds back to a bank account — a transfer sends the assets straight to another wallet you specify, leaving the Byzantine vault flow entirely.

Transfers are authorized by the account's signer with their passkey, so no intermediary (Byzantine or the integrator) can move the funds on the user's behalf.

<Info>
  Only on-chain currencies are supported for transfers: `usdc` and `eurc`.
</Info>

## What the endpoint does

[`POST /v1/query/get-transfer-payload-passkey`](/api-reference/transactions/get-transfer-payload) returns the raw transaction payload the user must sign to send assets from their account wallet to the destination address. It takes:

* `accountId` — the Byzantine account the funds are transferred from.
* `currency` — the on-chain currency to transfer (`usdc` or `eurc`).
* `amount` — the amount to transfer.
* `destinationAddress` — the wallet address that will receive the funds.

Signing follows the same two-step pattern as deposits and withdrawals:

<Tabs>
  <Tab title="Passkey">
    1. [Get transfer payload](/api-reference/transactions/get-transfer-payload), which requests the transaction body to sign.
    2. [Sign a payload (passkey)](/api-reference/transactions/sign-payload), which submits the signed transaction and executes the transfer.
  </Tab>
</Tabs>

<Warning>
  On-chain transfers are **irreversible**. If the `destinationAddress` is incorrect, malformed, or otherwise not a valid wallet the user controls, the funds will be sent there anyway and **lost permanently** — they cannot be recovered by Byzantine or the integrator. Always validate the destination address before signing the transfer.
