On-Off Ramp
In this section, you'll learn how to use Cashramp to on-off ramp stablecoins to/from a DApp/self-custodial wallet.

CUSD | CELO | On-ramp, Off-ramp | $0.1 |
USDC | OP | Off-ramp | $0.5 |
An API key is all you need to get started with onchain on-off ramping. You can create yours by following the authentication steps.
The on-off ramp flow is accessible via a URL that can be customized to your specific use case with query parameters.
- Staging: https://staging.useaccrue.com/hosted/ramp
- Production: https://useaccrue.com/hosted/ramp
- key (required): Your public key.
- paymentType (required): Either
depositorwithdrawal - address (required): The wallet address you want to deposit into or withdraw from
- coin (required): The stablecoin you want to deposit/withdraw
- network (required): The network you want to deposit/withdraw via
- amount (optional): The quantity of the stablecoin you want to deposit/withdraw
- currency (optional): The ISO 4217 currency code

If you're using the Onchain Ramp webpage/widget in a browser with a
window.ethereum object available, during the offramp flow, we will automatically initiate a transaction signing prompt for any injected wallet (Rainbow, Metamask).However, if
window.ethereum isn't available, we send a message event that you can listen for and spin up your customized experience for sending in crypto from a user's wallet address to the Cashramp Escrow Address.window.addEventListener("message", (message) => {
if (message.origin === "https://useaccrue.com") {
const { event, payload } = message.data;
if (event === "crypto.requested") {
const amountUsd = parseFloat(payload.amountCents) / 100;
const destinationAddress = payload.destinationAddress;
// Here's where you add your custom experience for sending the *exact*
// USD amount to Cashramp's Escrow Address (destinationAddress)
}
}
});
