Payouts
Stablecoins API to execute a payment.
What is a payout?
A payout is an operation that moves funds from the sender's wallet to the receiver's bank account.
The payout can only be executed if a quote was created previously, and you have 5 minutes to execute the payout before the quote expires.
Please review how BlindPay manages the stablecoins in the flow of funds explanation.
How to mint USDB?
USDB is a fake ERC20 stablecoin powered by BlindPay to simulate payouts on development
instances.
You can mint infinite USDB, but you need to add Ether to your wallet, so please get some Ether from https://www.alchemy.com/faucets/base-sepolia.
Go to https://app.blindpay.com/mint/ and mint USDB on Base Sepolia Testnet
.
Remember: we're using Base Sepolia Testnet
in all the examples below, so please double check you're doing everything on the correct network.
Approving tokens for being moved by BlindPay
All stablecoins supported by BlindPay are ERC20 tokens, so you need to call the approve
method on the token contract to allow BlindPay to move the funds from any blockchain wallet.
Before approving the tokens, you need to have:
- A RPC provider URL from Base Sepolia Testnet
- A blockchain wallet with enough funds to execute the transaction
- The private key or any way to instantiate the blockchain wallet using ethers.js
- ERC20 token contract address (Provided by BlindPay on Quote API response)
- ERC20 ABI (Provided by BlindPay on Quote API response)
- BlindPay smart contract address (Provided by BlindPay on Quote API response)
To simulate an approval, we're going to use JavaScript to install express.js server and ethers.js library.
Before start, please ensure you have Node.js installed.
Now create a folder called approve-erc20
. Inside the folder, please run the following command:
And now install the dependencies:
Now create a file called index.js
inside it, paste the code below and replace the values with your own.
Now run you can run the code using the following command:
Now access http://localhost:3000 and after some seconds you should see a result like this in your browser:

Before creating a payout, you need to:
- Create an account on BlindPay
- Create a development instance
- Create your API key

Remember: replace YOUR_SECRET_TOKEN
with your API key, in_000000000000

with the quote you generated previously and sender_wallet_address
with the same wallet address that you used to approve the tokens.
Congratulations! You've completed your first payout using BlindPay. If you want to execute more payouts you need to create a new quote and approve the tokens again.
