BOB is building the Bank of Bitcoin, reimagining banking for the Bitcoin age. One platform for everything: swapping, saving, earning, and borrowing, all on Bitcoin rails.

The first critical stage in making this vision a reality is delivering the best swaps engine for native BTC, enabling secure, non-custodial, on and off-ramping into a new Bitcoin banking system.

Currently, more than 50% of all Bitcoins that will ever be mined - approximately 12M BTC - are sitting in self-custody wallets rather than trusting an exchange or institution. Despite this, less than 1% of monthly BTC swap volume is carried out onchain in a non-custodial manner.

‍

BTC swaps is an underserved $800B monthly market

Bitcoin swaps represent a massive and growing market. Approximately $800B in BTC swaps occur every month, predominantly on centralized exchanges. Even though the majority of Bitcoin is held in self-custody wallets vs on exchanges, only $400M of this total comes from onchain swaps - because the experience of executing those swaps often remains frustratingly poor. By improving this swaps experience we can migrate more of this huge demand onchain - and if just 1% of CEX swaps can be captured, that is already an almost 2000% increase in volume, equivalent to $8B per month.

‍

The current onchain swaps experience can push people to centralized platforms

Today's onchain BTC swap experience is defined by uncertainty and delay, which is why people often still use centralized exchanges and platforms, despite custody risk and withdrawal fees.

Painfully slow: Swaps require waiting for Bitcoin confirmations, leading to 10–30+ minute delays that create stress and missed opportunities.
Price slippage: This delay means users never quite know how much they'll receive by the time a swap completes. Slippage can eat into value with as much as 1%+ of the total swap value disappearing without warning - the slippage is almost always hidden from the user until it’s too late.
Missed DeFi opportunities: Slow finality and price uncertainty can mean stale quotes and failed swaps, cutting users off from time-sensitive trading and DeFi positions. This is particularly important during DeFi liquidations where swift transfers are critical.

Protocols like Lightning, Spark and Ark have attempted to address these issues by implementing faster swaps, but these designs come with different compromises. They require setup and pre-funding of an account on a specific wallet, often have thin liquidity, and lack support for stablecoins and most major smart contract chains. They sit adjacent to the existing DeFi ecosystem, unable to integrate with it. When faced with all these hurdles, it often still makes more sense for someone to continue swapping on an exchange.

Instant, fixed-rate Bitcoin swaps are the solution

BOB is transforming the native BTC swap experience:

Instant liquidity - Swap from native BTC in under 10 seconds, then immediately swap again or deploy into DeFi. No more waiting and wondering. No more missed DeFi opportunities. After Bitcoin confirmation, you can use your swapped assets in any way you like.
Zero slippage - Never receive less than you expect again. Honest quotes mean you always know exactly how much you'll receive before you commit.

Powered by zero-conf technology, these improvements are already being discussed with leading swaps aggregators, so we can raise the bar for the BTC swap experience across the ecosystem.

Register your interest if you’d like early access to the future of BTC swaps. Existing BTC swappers could also qualify for fee-free swaps on BOB Gateway.

BOB Gateway is already optimized for native BTC swaps

Best-in-class BTC routing - Heavily optimized BTC swaps engine for the best quotes across 11 chains, including Ethereum, Base, BNB Chain, Avalanche, and Unichain. And the routes are expanding fast.
Non-custodial & trust-minimized - Native BTCFi powered by Bitcoin intents and atomic cross-chain swaps.
CEX on/off-ramps - Users can swap and deploy directly from their favourite exchange, with no Bitcoin wallet required.
Direct BTC deposits into DeFi: Lets users enter DeFi positions directly from native BTC with just a single transaction.
Advanced BTC trading features in development - Including fixed-rates, instant liquidity, AI agent integration, limit orders, DCA, and more.

For DeFi builders, BOB Gateway makes it easy to ship BTC flows in under a week through its B2B-focused, API-first interoperability layer:

Enterprise grade compliance - Advanced wallet and transaction screening to protect against illicit fund flows.
Native hardware wallet support - Ledger, Trezor and Onekey hardware wallets are supported out of the box.
Fast API integration - Uses the OpenAPI standard and includes BTC wallet support, powered by Reown.
Agentic tooling support - Compatible with and discoverable by EVM AI tooling stacks.

Zero-Confirmation Swaps are the next big upgrade

This is the next level of innovation in Bitcoin intents. Zero-conf technology makes instant and fixed-price BTC swaps a reality, while providing smart double-spend protection.

Swaps complete in under 10 seconds meaning no more disappointment from incorrect quotes and no more missed opportunities while waiting for Bitcoin finality.

Unlike other fast BTC swaps protocols, zero-confirmation swaps do not require any pre-staking, pre-deposit, or account setup. Within seconds, the destination asset will be available to be swapped further or deployed into whitelisted DeFi positions.

This opens up a whole new class of integrations for BOB Gateway, providing non-custodial BTC access for wallets, dapps and aggregators:

Wallets: Higher conversion and honest rates, where users know exactly what they’ll receive. Faster BTC to stablecoin swaps with fewer drop-offs.
DeFi apps: Near-instant BTC onboarding into lending, LP positions, and vaults. Supports urgent flows including rebalancing and liquidation defense.
Bridge and swap aggregators: Fixed-outcome BTC routes with fewer re-quotes and failed swaps. A fast, differentiated execution path that improves end-user experience.
On/off-ramps and payments: Reliable, fast BTC to stablecoin conversion where the delivered outcome matches the quote - a win for both merchants and users.

As we get closer to launch, we will share much more detail on how zero-conf technology works and how it protects against double spend attacks. Join the waitlist to stay up to date, and be one of the first to try it out. Existing BTC swappers could also qualify for fee-free swaps on BOB Gateway.

The Bank of Bitcoin

The best BTC swaps engine is just the first step. BOB's broader mission is to build the full banking stack on Bitcoin

Three Bitcoin banking pillars

BOB Gateway: Native BTC swaps are the on-ramp, enabling deposits and DeFi deployments across 100+ chains. Any wallet or fintech can plug in. Every transaction routes through BOB, generating protocol revenue.
Native Bitcoin Vaults: A savings and lending engine that turns idle BTC into productive collateral. Borrow stables, earn yield, and always receive your exact sats back on Bitcoin.
A frictionless consumer app: Imagine borrowing against your BTC for everyday spending. This is just one Bitcoin banking product that becomes possible once BOB builds out the full stack.

The $6 trillion endgame

If even a fraction of the trillion-dollar markets move onto Bitcoin rails - consumer deposits, lending, mortgages, trade finance - the numbers get serious. Hundreds of billions in loan volume. Hundreds of billions in productive TVL. Every swap, every loan, every vault deposit generating fees.

That's the $6 trillion endgame. Not just better products - a different architecture entirely. One where the value that used to leak to intermediaries stays with the people who created it.

BOB will be the Bank of Bitcoin. And it starts with building the best BTC swaps engine.
