Question 1

What is BOB Gateway?

Accepted Answer

BOB Gateway is an intents-based swaps engine for native BTC. It lets you swap native Bitcoin into stablecoins, tokenized gold, ETH, wBTC, and DeFi positions across 11 major chains - all in a single transaction, without bridges, wrappers, or custodians.

Question 2

Why is BOB Gateway the best swaps engine for native BTC?

Accepted Answer

BOB Gateway has been specifically optimized for native BTC swaps. It combines the best quotes, the lowest fees, and the simplest experience for native BTC swaps. It's non-custodial and trust-minimized, supports 11 chains, works with hardware wallets and CEX accounts out of the box, and requires no ETH for gas.

Question 3

What assets can I swap on BOB Gateway?

Accepted Answer

You can swap native BTC for stablecoins (USDC, USDT, cbBTC, DAI, EURC, PYUSD), tokenized gold (XAUT, PAXG), ETH, wBTC, LINK and AVAX.

Question 4

What chains does BOB Gateway support?

Accepted Answer

BOB Gateway supports multiple major chains, including Ethereum, Base, Arbitrum, BNB Chain, Avalanche and Optimism. Tron and Solana support is coming soon.

Question 5

What are Bitcoin intents?

Accepted Answer

Bitcoin intents let you specify the outcome you want - "swap my BTC for USDT on Base" - and Gateway handles the execution. You don't need to manage bridges, wrappers, or multi-step routing. Under the hood, solvers lock liquidity in smart contracts on BOB, you send BTC on Bitcoin, and an on-chain Bitcoin Light Client verifies the transaction and triggers settlement.

Question 6

How long does it take to complete a swap?

Accepted Answer

On average 5-10 minutes. Bitcoin blocks are mined roughly every 10 minutes, so the wait is mainly Bitcoin confirmation time. Once BTC is received, swap processing takes only a few seconds. Instant swaps are also under development.

Question 7

What fees do I need to pay?

Accepted Answer

BOB Gateway offers some of the lowest fees on the market for BTC swaps. There are a few components: a solver spread, gas costs on the destination chain (estimated upfront and deducted automatically - you don't need ETH on BOB) and protocol fees. Current BOB Gateway fees are approximately 0.025% for swaps larger then 0.05 BTC - easily the cheapest in the market.

Question 8

Do I need to do ID verification to use BOB Gateway?

Accepted Answer

You can swap directly without creating an account or submitting any identity verification.

Question 9

Which wallets does BOB Gateway support?

Accepted Answer

The BOB app allows you to connect 500+ wallets including Metamask, Rabby, Ledger, Fireblocks, Binance Web3 Wallet, OKX Wallet, and many many more.

Question 10

Can I use a hardware wallet with BOB Gateway?

Accepted Answer

Yes. You can use a hardware wallet with BOB Gateway either directly or by adding the account to a browser extension wallet such as Rabby or Metamask.

Question 11

Do I need a Bitcoin wallet to do a BTC swap?

Accepted Answer

No. It is possible to swap by sending BTC directly from a centralized exchange. You will still need to connect your EVM wallet to receive the destination assets. Initiate this process by only connecting an EVM wallet then request a swap amount. The BOB app will provide a wallet address and amount of BTC to send from your CEX.

Question 12

Can I swap BTC directly from a centralized exchange?

Accepted Answer

Yes. You can initiate a swap, connect only your destination EVM wallet, and send BTC directly from your CEX account - no Bitcoin wallet connection required. This works with Binance, Coinbase, and other major exchanges. It's important to send the exact amount shown within the required time window for the swap to complete. Initiate this process by only connecting an EVM wallet then request a swap amount. The BOB app will provide a wallet address and amount of BTC to send from your CEX.

Question 13

Do I need any BOB tokens or ETH to use BOB Gateway?

Accepted Answer

No. The relayer estimates and covers gas costs upfront, deducting them from the transaction. You don't need BOB tokens or ETH to use the swap.

Question 14

Are instant and fixed-rate swaps live?

Accepted Answer

Not yet. Instant swaps (completing in under 10 seconds) and zero-slippage fixed-rate swaps are in active development.

Question 15

What measures are taken to prevent money laundering?

Accepted Answer

BOB Gateway works with a professional wallet screening partner that checks whether connected wallets are associated with known criminal activity or sanctioned countries. Any wallet flagged in this screening will be blocked from using the service.

Question 16

I wanted USDT on Ethereum but received wBTC on BOB instead?

Accepted Answer

This is the fallback for failed second-step swaps. Swaps happen in two stages: (1) BTC → wBTC and (2) wBTC → USDT. If stage 2 fails - because the quote timed out or BTC's price shifted too much during Bitcoin confirmation - you receive wBTC on BOB. You can bridge the wBTC to Ethereum and swap it for USDT manually. Automatic recovery is in development.

Question 17

Where can I ask for support?

Accepted Answer

Join the BOB Discord and submit a ticket. One of the BOB team will help you.

Question 18

How does a BTC swap work on BOB Gateway?

Accepted Answer

(1) Solvers lock a routing asset, for example wBTC or USDT0, in a smart contract. (2) You send BTC on the Bitcoin network. (3) An on-chain Bitcoin Light Client verifies your transaction, unlocks the routing asset, and initiates the swap into your target asset on your target chain.

Question 19

Does BOB Gateway take custody of my assets?

Accepted Answer

No. BOB Gateway uses atomic cross-chain swaps and an on-chain Bitcoin Light Client. At no point does BOB or any third party take custody of your assets. The protocol is trust minimized - solvers cannot take your Bitcoin without completing the swap, and you cannot receive tokens without sending BTC.

Question 20

Has BOB Gateway been audited?

Accepted Answer

Yes. The protocol has been audited by Pashov and Common Prefix. Each new protocol upgrade and new feature is also audited before launch.

Question 21

How easy is it to integrate BOB Gateway into a dapp?

Accepted Answer

Dapps can integrate BOB Gateway within a few days via OpenAPI, using standard tooling and a production-grade interface. BOB Gateway is designed to be embedded by wallets, exchanges, aggregators, and apps.

Question 22

What is the difference between the BOB Gateway API and SDK?

Accepted Answer

The API alone is enough to access all supported routes, while the SDK enables more advanced use cases and deeper product integration. A new simulation environment also makes it easier to test and validate integrations before going live.

Question 23

How do I get support from the BOB team with integrating the Gateway API/SDK?

Accepted Answer

Please create a ticket in the BOB Discord. The mods will be able to share your information with the BOB team.

Question 24

Can dapps that integrate Gateway earn revenue from user swaps?

Accepted Answer

Yes. BOB Gateway allows custom monetization by integrators, plus dapps can earn volume based rewards via the BOB affiliate program.
