Onboard Exchange enables seamless fiat-to-crypto (onramp) and crypto-to-fiat (offramp) transactions.

Compatible with any EVM-compatible dApps or wallets, Exchange allows anyone get onchain in less than 3 minutes, supporting micro-transactions of as little as $0.5 at near zero-fees

Letā€™s explore how an end user experiences an Onboard trade, from start-to-finish.

Transaction lifecycle

1

Start in Your dApp or Wallet

Alice, a user in Kenya, wants to purchase USDC to deposit into a DeFi protocol. She opens her Web3 wallet (integrated with Onboard) and selects the Buy Crypto option.

2

Select offer

Alice inputs her desired amount (e.g., 5 USDC) and chooses her fiat payment method (M-PESA). Her wallet connects to Onboard, which either:

  • Matches her with the best available offer for her amount and trading pair.
  • Or shows a list of offers, sorted by rate, availability, and completion time.

Alice selects Bobā€™s offer, which she believes has the best rate.

3

Initiate transaction

Alice confirms her wallet address and the transaction details. The order is initiated, and Bobā€™s 5 USDC is locked securely in Onboardā€™s escrow.

4

Make payment

Alice views Bobā€™s payment instructions on-screen, and via her M-PESA app, transfers the equivalent amount in Kenyan Shillings (KES) to Bobā€™s account.

5

Crypto released

Once Bob confirms receipt of the KES, Onboard releases the 5 USDC from escrow directly to Aliceā€™s wallet. Alice is notified that her transaction is complete.
