## Relay Overview

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](https://docs.relay.link/references/protocol/overview)
- Comprehensive DEX Meta-Aggregation across 85 chains

This makes Relay a powerful solution for a diverse set of use cases:

### Bridging & Onboarding

Instant Bridging between 85+ Chains. [Learn More](https://docs.relay.link/use-cases/bridging)

### Swaps

Same-chain & Cross-chain Swaps on Every Chain. [Learn More](https://docs.relay.link/use-cases/cross-chain-swaps)

### Call Execution

## 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](https://relay.link/)

### 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](https://docs.relay.link/references/api/overview)

### 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](https://docs.relay.link/references/protocol/overview)

## 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.
