Off-Ramp

Overview

Off-ramp accounts let your recipients convert USDC or USDT to USD. Each off-ramp account has a dedicated crypto deposit address — send stablecoins to it, and USD is delivered to the configured bank account via ACH, Fedwire, or SWIFT.

How It Works

Recipient Has KYB + Address

The recipient must be KYB-approved and have a physical address on file. Include the address when creating the recipient, or update it later.

Create Off-Ramp Account

Call POST /v1/ramp/recipients/{id}/offramp-accounts with the source wallet, payment rail, and bank details.

Receive Crypto Deposit Address

The response includes a source_crypto_address — this is the address where USDC/USDT should be sent.

Send Stablecoins

Send USDC or USDT to the deposit address from any wallet.

USD Delivered

The stablecoins are converted to USD and delivered to the configured bank account. Fees are deducted automatically.

Creating an Off-Ramp Account

curl -X POST "https://api.rebelfi.io/v1/ramp/recipients/1/offramp-accounts" \
  -H "x-api-key: your_api_key" \
  -H "Content-Type: application/json" \
  -d '{
    "org_wallet_id": 42,
    "source_asset": "USDC",
    "rail": "ach",
    "bank_details": {
      "routing_number": "021000021",
      "account_number": "987654321",
      "account_type": "checking",
      "account_holder_name": "OnEdge Inc",
      "bank_name": "Chase Bank"
    }
  }'

Parameters

Parameter	Required	Description
`org_wallet_id`	Yes	Source wallet ID
`source_asset`	No	Crypto asset to accept (default: `USDC`)
`rail`	No	Payment rail: `ach`, `fedwire`, or `swift` (default: `ach`)
`bank_details`	Yes	Bank account for USD delivery

Response

{
  "id": 1,
  "source_crypto_address": "0xABC123...",
  "source_asset": "USDC",
  "destination_asset": "USD",
  "network_id": "solana-mainnet",
  "rail": "ach",
  "fiat_bank_name": "Chase Bank",
  "fiat_account_type": "checking",
  "fiat_account_holder_name": "OnEdge Inc",
  "status": "active"
}

The source_crypto_address is the deposit address. Share this with the recipient or use it programmatically to send USDC/USDT for conversion.

Transaction Events

Off-ramp transactions fire dedicated webhook events:

offramp_transaction.completed — USD successfully delivered to bank account
offramp_transaction.failed — conversion or delivery failed

See Webhooks for full payload details.

What to Do With On-Ramped Stablecoins

Once USDC/USDT lands in your wallet via on-ramp, you can deploy it to earn yield using RebelFi’s yield infrastructure. See our yield documentation to learn how to generate 5-8% APY on your on-ramped stablecoins.
