Convert Between Currencies

Swap between BTC, USDT, and fiat currencies within your Neutron wallet. Settles instantly -- no network fees.

How It Works

Both sides use method: "neutronpay" since funds stay in your wallet:

curl -X POST https://api.neutron.me/api/v2/transaction/ \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer YOUR_ACCESS_TOKEN" \
  -d '{
    "sourceReq": {"ccy": "BTC", "amtRequested": 0.001, "method": "neutronpay", "reqDetails": {}},
    "destReq": {"ccy": "USDT", "method": "neutronpay", "reqDetails": {}}
  }'

Response:

{
  "txnId": "a1b2c3d4-...",
  "txnState": "quoted",
  "sourceReq": { "ccy": "BTC", "amtRequested": 0.001 },
  "destReq": { "ccy": "USDT", "amtRequested": 97.50 },
  "fxRate": 97500.00
}

Review the rate, then confirm to execute.

Supported Pairs

From	To	Example

BTC	VND, USD, CAD	Bitcoin to fiat
USDT	BTC	Stablecoin to Bitcoin
USDT	VND	Stablecoin to fiat

Amount Logic

Set amtRequested on one side only:

Source side: "Convert this much" -- Neutron calculates what you receive
Dest side: "I want this much" -- Neutron calculates what it costs
