Move Anything. Any Chain. Instantly.
Cross-Chain Infrastructure for the Onchain Economy
Bridge, swap, and pay across 85+ chains in seconds. Payments-grade speed, cost, and reliability ? built for wallets, apps, and real volume.
What Relay Helps You Do
Blockchain Interoperability
Relay connects chains so apps and users can move data and assets across Web3.
DEX Aggregator Routing
DEX aggregator routing compares pools and paths. You get smarter routes and lower slippage on token swaps.
Blockchain API & SDK
Use the Relay API to add bridges, swaps, and wallet flows. One multichain stack for Web3 builders.
Multichain Wallet Ready
Power multichain and smart wallets with Relay rails. Users keep self-custody while moving assets across chains.
Built for Multichain Apps
Cross-Chain Interoperability
Move tokens and messages between chains. Relay makes cross-chain transfers fast enough for real products.
Best-Rate Swaps
Smart routing finds better paths across pools and chains so your swaps fill closer to the quote.
