The largest aggregator of on-chain DEX routes and bridges. 20+ protocols queried simultaneously so you always get the most tokens for your trade, on any chain.
Swap now
Swapping on a single exchange means you're leaving money on the table. Liquidity is fragmented across dozens of protocols, chains, and bridges and no single DEX can see all of it.
The best rate for your trade might be sitting on Uniswap, Jupiter, CowSwap, or a bridge you've never heard of. Most platforms only check one source, show you that rate, and call it done. You'd have to open five tabs, run the same swap on each, and compare manually.
Bridge fees, protocol fees, gas, and slippage are often only visible after you've already signed. The number shown at the top of the screen and the number that actually lands in your wallet can be very different. By the time you notice, it's too late to change anything.
Cross-chain swaps shouldn't require three different platforms, two separate wallets, and a tutorial. Most people end up either overpaying out of convenience or wasting time hunting for a better deal. There's no good reason it has to work that way.
Enter your token pair and amount. Houdini queries 20+ on-chain protocols and aggregators simultaneously. Approve and sign the transaction directly from your wallet. All WalletConnect-compatible wallets are supported.
Your funds are routed automatically through audited smart contracts. Token A is converted to Token B with no custodian, no middleman, and no manual steps. Token B lands directly in your designated wallet on the target chain. Fast, verifiable, and fully on-chain.
Token B lands directly in your designated wallet on the target chain. Fast, verifiable, and fully on-chain.
When you swap on a single exchange, you're trusting one platform to have the best rate, the deepest liquidity, and the lowest fees — all at once. That's rarely how it works. Liquidity is scattered across dozens of protocols, chains, and bridges, and no single DEX can see all of it. The result is you pay more than you should, almost every time.
Houdini checks Uniswap, Jupiter, SushiSwap, CowSwap, Mayan, ChainFlip, and more all at once. The best route wins — you don't have to look.
Every fee — protocol, bridge, slippage — is factored into the quoted amount before you sign. What you see is what you get.
Every swap is 100% verifiable on-chain. Houdini never holds your funds. The exchange happens directly between you and the liquidity source.
EVM chains including Ethereum, Arbitrum, Polygon, BNB and more. Plus Solana, Bitcoin, Sui, Tron, and Stellar. If it exists on-chain, you can swap it.
Most swaps complete in 5 seconds to 3 minutes. Same-chain swaps are near-instant. Cross-chain routes are optimised for speed, not just price.
Speed and price aren't luxuries. They're the whole point. Whether you're chasing an entry, moving funds cross-chain, or building an app that needs reliable execution, Onchain / DEX swap is built for the moments where every basis point and every second counts.
Stop settling for whatever rate a single DEX puts in front of you. Houdini queries 20+ protocols simultaneously and routes your trade through the best one; often beating what you'd get by going to Uniswap, Jupiter, or SushiSwap directly. The difference adds up fast, especially on larger trades.
Full on-chain execution. Audited smart contracts. Every transaction publicly verifiable on the blockchain, start to finish. No off-chain routing, no intermediaries, no trust required. If transparency and decentralisation matter to you, this is how swaps should work.
