Relay is a multichain payments network, designed to make swapping and transacting across 100s of chains delightfully simple. Since launching in 2024, Relay has served 5M users, processed 50M transactions, and driven $5B+ in volume across 85+ networks. It combines two core components:
  • Instant low cost cross-chain intents, powered by the Relay Protocol
  • Comprehensive DEX Meta-Aggregation across 85 chains
This makes Relay a powerful solution for a diverse set of use cases: To see Relay in action, and test supported routes, try the Relay App. To start building, check out the Integration Guide.

The Relay Stack

Built as a full-stack solution for every layer of the multichain payments experience:

Relay App

For everyone who wants to swap tokens across chains - The fastest way to go from any token to any token across chains. Swap ETH on Ethereum for SOL on Solana in one transaction — built on the same infrastructure that powers enterprise customers. Try the App

Relay API

For developers building multichain experiences - One integration, 75+ chains, zero complexity. Abstract the hardest parts of multichain development:
  • Bridge instantly between chains with predictable fees
  • Swap seamlessly using meta-aggregation across all major DEXs
  • Deliver payments-grade UX with gas sponsorship, guaranteed rates, and SLAs
Whether you’re building wallets, marketplaces, or consumer apps, Relay makes crosschain payments fast, reliable, and invisible. View Documentation

Relay Protocol

The network powering it all - The open system connecting users to relayers who execute onchain actions with maximum capital efficiency. Designed for low gas costs, rapid chain expansion, and enterprise-grade reliability. Learn More

Payments-Grade Reliability

Unlike traditional bridges, Relay delivers the reliability users expect from modern payments:
  • 99.9% uptime across 85+ networks
  • Fast execution instead of multi-minute wait times
  • Automatic redundancy systems ensuring transactions complete
  • Clear completion signals for apps and users

Trusted by Leading Teams

Chain Expansion: Alchemy, Conduit, and Caldera rely on Relay to provide payment rails to every rollup out of the box. Chain Abstraction: OpenSea powers crosschain mints through Relay so collectors never worry about which chain they’re on. Phantom collapses complex swaps into seamless flows. Multichain Infrastructure: Apps like OneBalance route execution through Relay, letting users access opportunities across chains as easily as checking their balance.
