TLDR
Optimex has integrated Across Protocol’s smart contracts to enable fast, non-custodial swaps between native Bitcoin and major EVM chains. Your BTC stays on the Bitcoin network while Across powers the EVM side for secure, low-cost execution.
Introduction
Your BTC just got a passport.
For the first time, you can swap native Bitcoin into (and out of) the EVM landscape without wrapping, custodians, or slow, clunky bridges.
Optimex has integrated Across contracts deep into its infrastructure to make it happen.
What is Optimex?
Optimex unlocks the utility of native Bitcoin by enabling programmable finance directly on the Bitcoin network. Swap, lend, and borrow BTC without wrapping tokens, relying on bridges, or giving up custody.
Powered by advanced cryptography and multi-party computation (MPC), Optimex delivers high-capital-efficiency tools while staying true to Bitcoin’s core principles: security, transparency, and real ownership. With over $2 trillion BTC sitting idle worldwide, Optimex turns dormant value into active, programmable capital.
Across Powers Crosschain Swaps on Optimex
Optimex has integrated Across Protocol’s smart contracts to complete the EVM side of their native BTC <> EVM swap flow, supporting Arbitrum, Optimism, Base, and BSC.
The integration connects the best of both worlds:
Optimex handles the Bitcoin leg. It’s secure, non-custodial, and native to the BTC network. Your BTC never leaves the Bitcoin blockchain.
Across powers the EVM leg. It powers fast, capital-efficient execution between EVM chains, all secured by UMA.
Here’s what this means for BTC holders:
Full-cycle capital mobility: Move value into DeFi ecosystems and back, without ever bridging your BTC.
Native custody: Keep full control of your Bitcoin at all times.
Fast & predictable: Across ensures low-cost, trust-minimized transfers with no slippage surprises.
Whether you’re funding a DeFi strategy on Arbitrum or taking your gains back to Bitcoin, the process is seamless and the BTC you own stays on the Bitcoin network the entire time.
Swap BTC across chains on Optimex, powered by Across.
The Future of Bitcoin is Crosschain
Bitcoin liquidity is no longer siloed from the rest of web3. With Optimex and Across, it can flow freely without sacrificing the principles that make Bitcoin one of the most trusted assets in crypto.
Fast. Secure. Non-custodial. Exactly how crosschain should be.
