One [Relay](/what-is-relay) integration gives you quotes, execution, and tracking across supported assets and networks. **Swap Meta-Aggregation** - We aggregate the best swap providers across crypto to deliver the best routes for onchain swaps **Instant Cross-chain Swaps** - Relay's median bridge time is 2.7 seconds across chains. **Multi-VM Support** - Relay Supports major EVM chains, as well as Bitcoin, Solana, Tron, Eclipse, and more. **Gasless Support** - Relay supports gasless swaps via native support of 4337 account abstraction, 7702 support, and gasless permit execution (3009 and 2612) **App Fees** - Our comprehensive approach to [App Fees](/features/app-fees) lets you easily earn when using Relay. Additionally, we have designed our fee system for you to automatically collect fees in stables (USDC). ## How it Works Your application requests a quote from the platform, and the user executes the returned steps. Same-chain swaps execute on the source chain; cross-chain orders use a solver's capital to fill on the destination chain. The platform tracks completion; [Relay Protocol](/references/protocol/overview) describes the separate settlement flow for orders that use its Depository contracts. To learn how to integrate Relay into your application, check out our [Quickstart Guide](/references/api/quickstart).
