Let users move between crypto and fiat currencies. Blaaiz supports collecting stablecoins (on-ramp) and paying out to crypto wallets (off-ramp) alongside traditional fiat rails.

​
On-ramp: Crypto to fiat

Accept stablecoin deposits from users and settle the value into your fiat wallet, or hold the balance for future fiat payouts.

​
How it works

​
Step-by-step

  1. Get supported networks — Call Get crypto networks to retrieve available networks and tokens.
  2. Initiate a crypto collection — Call Initiate crypto collection with the amount, token, and network. You receive a deposit address.
  3. Display to your user — Show the deposit address and network in your UI. The user sends stablecoins from their external wallet.
  4. Confirm receipt — Listen for the collection.completed webhook. Once confirmed, the equivalent value is credited to your wallet.
  5. Convert to fiat — The collected value lands in your business wallet. From there you can create a fiat payout to the user’s bank account, or swap to another currency.

​
Off-ramp: Fiat to crypto

Send funds from your fiat wallet to a user’s crypto wallet address. This lets users withdraw their balance as stablecoins.

​
How it works

​
Step-by-step

  1. Collect the user’s wallet details — Get the user’s wallet address, token, and network.
  2. Preview fees — Call Fee breakdown to show the user the network fees and any conversion costs.
  3. Create a crypto payout — Create a payout with method: "crypto_wallet" and include the wallet_address, wallet_token, and wallet_network fields.
  4. Track delivery — Listen for the payout.completed webhook to confirm the on-chain transaction was sent.
Crypto payout support varies by token and network. Contact support@blaaiz.com to confirm which crypto payout rails are available for your business.
