Why Gateway?
Gateway is the cheapest and easiest way to integrate native BTC swaps into your app, wallet, or aggregator. Integrate once via the SDK or API to offer your users best-in-market prices for native BTC swaps — across stablecoins, tokenized gold, wBTC, and more — without building or maintaining swap infrastructure. Gateway handles routing, solver liquidity, on-chain verification, and cross-chain settlement. You earn configurable revenue on every swap. No custody at any point. The market opportunity is significant. BTC↔stablecoin is the single largest trading pair in crypto — accounting for 90% of all BTC swap volume. But almost all of it still flows through centralised exchanges, because competitive onchain infrastructure for native BTC hasn’t existed until now. Gateway closes that gap.What is BOB Gateway?
BOB Gateway is a permissionless, intents- and RFQ-based protocol for native BTC swaps and 1-click BTCFi. It is currently offers the cheapest rates for BTC↔stablecoin (USDT, USDC), BTC↔wBTC swaps, and BTC↔tokenized gold swaps for all the most popular trade sizes — helping drive higher conversion rates for integrators.Integration Guide

Configurable Revenue
Set a custom fee on every swap your integration processes. Gateway handles routing, execution, and settlement — you earn on volume without infrastructure overhead.
Non-Custodial
Non-Custodial
Atomic cross-chain swaps and an on-chain Bitcoin Light Client mean neither your app nor BOB ever holds user funds. Solvers cannot claim Bitcoin without completing the swap. Users retain custody throughout.
Simple Integration
Simple Integration
SDK and API with white-label options. Minimal integration effort to support native Bitcoin wallets, hardware wallets (Ledger, Trezor, OneKey), and CEX-to-onchain flows via QR swap.
How It Works
Quote Request
Your app calls the Gateway API with the user’s desired swap — for example, BTC to USDT on Base. Gateway returns a quote with routing, fees, and estimated output.
Solver Locks Liquidity
A solver locks the output asset in a smart contract, committing to complete the swap before the user sends any Bitcoin.
User Sends the Asset
The user signs a single Bitcoin or EVM transaction. Gas on the destination chain is estimated upfront and deducted automatically.
On-Chain Verification
BOB’s Bitcoin Light Client verifies the transaction on-chain and triggers settlement.
