/overview/coverage-and-economy/chain-tokens-partnersWhat is an Onchain DEX or Bridge Swap?
An Onchain Swap is the fastest and most cost-effective way to trade tokens while maintaining 100% decentralized execution. While Houdini Swap is famous for privacy, our onchain routing options are built for speed and price. We aggregate liquidity from every major source (DEX, bridge, cross-chain swap, intent-based swaps, etc.) to ensure you always get the best market rate without having to shop around.Core Features:
- Best Market Rates: Houdini Swap queries 20+ onchain protocols and aggregators simultaneously, including Uniswap, Jupiter, SushiSwap, Mayan, ChainFlip, CowSwap, and more, finding you the best route for your pair and amount. Our prices are often better prices than swapping on a single DEX or aggregator.
- Fully Decentralized: Every swap is enforced by smart contracts and is 100% verifiable on the blockchain. Houdini Swap never holds your funds. The exchange happens directly between you and the decentralized liquidity source.
- Fee Transparency: All fees, including protocol fees, bridge fees, and other “hidden fees” are factored into the quoted output amount before you sign. There are no surprises after the fact.
- Supported EVM Networks: Ethereum, BNB Chain, Base, Arbitrum, Polygon, Optimism, Avalanche, Monad, Sonic, HyperEVM, Mantle, Blast, zkSync Era, Linea, Fantom, Gnosis, Scroll, Metis, Manta Pacific, Mode, Celo, Berachain, Core Blockchain, Wanchain, HEMI.
- Supported Non-EVM Networks: Solana, Bitcoin, Sui, Tron, Stellar.
- Supported Wallets: MetaMask, Phantom, Coinbase Wallet, Ledger, Trust Wallet, Backpack, TronLink, Tonkeeper, Infinex and many more, including any WalletConnect-compatible wallet.
How it Works
The process uses advanced aggregation to move your funds through the most efficient on-chain path:- Get a Quote: Enter the token pair and amount. Houdini Swap queries thousands of onchain routes and instantly calculates the best available rate.
- Connect Your Wallet: Approve and/or Sign the transaction directly from inside your wallet.
- Exchange: Your funds are automatically routed through smart contracts where Token A is converted to Token B.
- Delivery: Token B is sent directly to your designated receiver wallet on the target chain.
