ETH ↔ BTC. USDT ↔ BTC. Any token, any chain — settled in seconds, in a single click.
For years, moving value between blockchains felt like crossing borders with paperwork in hand. Wrapping, bridging, waiting. A new generation of crosschain protocols rewrites that story — one click, native settlement, sub-second fills.
Traditional bridges lock liquidity and wait for finality on both chains. Flashswap uses a competitive solver network: solvers front the destination liquidity instantly, then settle in the background. The result is execution that feels closer to a payment than a trade.
Bitcoin, Ethereum, Solana, Base, Arbitrum, Optimism, Tron — thirty-plus networks become a single swap surface. Pick a token on the left. Pick a token on the right. The route, the bridges, the gas — all of it dissolves into a single confirmation.
One click. Native settlement. No manual bridging, no wrapped tokens to manage.
MetaMask, Phantom, Coinbase Wallet, OKX — every major wallet, EVM and non-EVM. No account, no KYC.
Any token on any chain on the FROM side, any token on any chain on the TO side. ETH → BTC, USDT → BTC, USDC Base → SOL.
Solvers compete for your order. Most swaps settle in under two seconds at the best market price, native to native.

Speed and fees are indicative averages reported by each protocol. Quotes vary with size, liquidity and network conditions.
Pick ETH on the FROM side and BTC on the TO side, enter an amount, connect your wallet and confirm. Solvers route the order across the best venues and settle native BTC to your address — typically under two seconds.
Yes. Flashswap supports USDT (Ethereum, Tron, BSC, Arbitrum…) and USDC (Ethereum, Base, Solana…) directly to native BTC. The reverse — BTC to USDT/USDC on any chain — works the same way.
You stay self-custodial: tokens move from your wallet to the destination wallet without ever sitting on a CEX. No signup, no withdrawal queue, no KYC for swaps.
Solvers front destination liquidity and compete for your order, so you get tight pricing and sub-2-second fills across 30+ chains.
30+ chains including Bitcoin, Ethereum, Solana, Base, Arbitrum, Optimism, Polygon, BNB Chain, Avalanche and Tron — plus most major stablecoins and ecosystem tokens.
