Auth method: Signed (HMAC) — this endpoint requires the full set of signed headers: x-access-id, x-request-id, x-timestamp, and an HMAC-SHA256 authorization signature. See Authentication.

This endpoint handles both native coin transfers (ETH, TRX, BTC) and token transfers (USDT, USDC) in a single call. Pass chain and currency. The transfer is submitted on-chain asynchronously. When the transaction confirms, Tender fires a SUB_USER_WALLET_TRANSFER_CONFIRMED webhook to your server. Supported chains: ethereum, tron, bitcoin

Example

// Native coin transfer (e.g. ETH on Ethereum)
const res = await fetch(`${BASE}/wallet/transfer`, {
  method: 'POST',
  headers: makeHeaders(),
  body: JSON.stringify({
    chain:              'ethereum',
    currency:           'ethereum',
    sender:             '0xabc123...',
    receiver:           '0x999fff...',
    amount:             0.01,
    merchant_reference: 'payout-9921',
    address_reference:  'slot-2',
  }),
});
const { data } = await res.json();
// data.tx_id → "0xabc123def456..."

// Token transfer (e.g. USDT on Tron)
const res2 = await fetch(`${BASE}/wallet/transfer`, {
  method: 'POST',
  headers: makeHeaders(),
  body: JSON.stringify({
    chain:              'tron',
    currency:           'usdt',
    sender:             'TXYZop...',
    receiver:           'TABCef...',
    amount:             50,
    merchant_reference: 'payout-9922',
    address_reference:  'slot-2',
  }),
});
const { data: data2 } = await res2.json();
// data2.tx_id → "abc123def456..."
