For Bitcoin holders, rotating into gold has long involved trade-offs between self-custody and convenience. BOB Gateway’s integration of XAUt0 and USDT0 eliminates this unnecessary trade-off entirely.
Starting today, Bitcoin holders can swap BTC directly into tokenized gold in a single transaction on BOB Gateway, with no intermediary holding funds at any point in the process. This marks one of the first opportunities for the Bitcoin community to have a direct, self-custodied path between the world's two most enduring stores of value.
Bitcoin and gold share a common identity. Both are scarce by design, both are held as long-term stores of value, and both sit alongside the traditional financial system. For many holders, they are not competing assets but complementary ones.
Moving between them has historically meant going through a centralized exchange, accepting custody risk, and navigating conversion steps that cut against the self-sovereign premise of holding either asset. BOB Gateway changes that. The BTC to XAUt0 flow is entirely self-custodied, with BTC holders able to simply specify the destination and receive XAUt0 on the target chain without any intermediate accounts or counterparty risk
More specifically, this integration enables:
Direct BTC to XAUt0 swaps on Ethereum Mainnet, with BNB Chain and additional destinations on the roadmap
Self-custodied gold exposure for Bitcoin holders who want to rotate into gold without a centralized intermediary
Single-transaction execution, with BOB Gateway handling all routing, gas abstraction, and cross-chain delivery automatically
Cross-chain XAUt0 delivery, maintaining unified gold-backed liquidity across supported networks
Underpinning the BTC to XAUt0 flow is USDT0, which serves as one of BOB Gateway's routing assets. Cross-chain swaps settle through USDT0 on Ethereum, enabling every USDT0-supported chain to become a natural BOB Gateway destination with no separate liquidity pools required per chain and no additional infrastructure overhead as coverage expands.
In short, BOB Gateway now has access to the USDT0 Network’s full asset suite: borderless dollar liquidity through USDT0, and physically backed gold through XAUt0.
BOB Gateway is an intent-based swap engine that lets Bitcoin holders move BTC into different assets and positions, whether they are swapping into stablecoins, tokenized gold, or ETH, or deploying directly into DeFi positions.
Users simply specify their intended outcome, and BOB Gateway handles everything else under the hood. This includes locking liquidity in smart contracts on BOB and verifying the incoming Bitcoin transaction to managing all gas and routing across networks and delivering the chosen asset to the destination chain.
The BOB Gateway API & SDK unlock direct Bitcoin access for ~15,000 apps across 11 chains, and the broader BOB ecosystem has processed over 47 million transactions to date. With USDT0 and XAUt0 now live, Bitcoin holders can add tokenized gold and borderless dollar liquidity to their list of onchain destinations.
Gold has preserved value across centuries, and Bitcoin has redefined what sound money looks like in the internet age. With XAUt0 and USDT0 now live on BOB Gateway, both assets are accessible within the same programmable environment. And the path between them is open to any Bitcoin holder, on their own terms.
Together, this integration marks the one of the first times the Bitcoin community has had a direct, self-custodied on-ramp between the world's two most enduring stores of value, powered by the USDT0 Network.
