# Relay Protocol

> Move anything, any chain, instantly

Relay Protocol is a cross-chain payments protocol that provides instant, low-cost bridging and swapping across blockchains. It connects users with relayers who execute transactions on their behalf across multiple networks.

Relay Protocol is a cross-chain payments protocol that provides instant, low-cost bridging and cross-chain execution. It is built for developers, wallets, and commerce platforms that need to move value across multiple blockchains, targeting price-sensitive use cases such as payments, bridging, NFT minting, and gas abstraction. The protocol underpins a wider stack of products, including an application, an API, and a developer toolkit, that connect users to the broader onchain economy.

The protocol addresses the friction of moving assets between separate blockchains by connecting users with relayers, financial agents that execute actions on a user's behalf across chains in exchange for a small fee. This design is intended to minimize gas costs and execution latency compared to conventional bridging methods, while supporting features such as fee sponsorship, gasless execution, and deposit addresses. It operates across a large number of supported networks rather than being tied to a single chain.

Beyond the core protocol, the offering includes an API for developers building multichain experiences, a developer toolkit for embedding cross-chain functionality, and a consumer-facing application for swapping and bridging tokens directly. It is used by wallets, multichain applications, payment processors, and commerce platforms seeking a single integration for cross-chain transfers, as well as individual users swapping tokens between chains.

## Products

- [Relay Bridge](https://thegrid.id/profiles/Relay): Relay Bridge is a cross-chain bridging and swapping product that moves assets between blockchains through relayer-based intent settlement. Users submit a transfer request and receive a quote, after which a relayer fills the transaction on the destination chain before funds are released on the origin chain, enabling fills in a few seconds. It supports same-chain and cross-chain swaps across a wide range of blockchains and is used by wallets and applications seeking fast, low-cost transfers. (Bridge, Live, Main Product)
- [Relay Vaults](https://thegrid.id/profiles/Relay): Relay Vaults is a liquidity provisioning product consisting of yield-bearing pools that supply capital for cross-chain settlement. Each vault is deployed on a specific network for a specific asset and follows the ERC4626 vault standard, depositing idle funds into an underlying lending protocol to generate base yield. Solvers draw on vault liquidity to instantly rebalance capital across chains, which speeds up withdrawals and lowers fees, and depositors earn additional yield streamed over time from solver activity. (Liquid Staking, Live)
- [Relay SDK](https://thegrid.id/profiles/Relay): Relay SDK, also referred to as RelayKit, is a developer tooling product that lets applications embed cross-chain bridging, swapping, and execution features. It provides prebuilt interface components, hooks, and programmatic access to Relay's quoting and execution flows for both EVM and non-EVM chains. Wallet providers and application developers use it to add cross-chain functionality without building the underlying infrastructure themselves. (Developer Tooling, Live)
- [Relay API](https://thegrid.id/profiles/Relay): Relay API enables developers to quote and execute cross-chain transactions programmatically. The API supports bridging, swapping, cross-chain execution, and provides real-time quotes with 30-second expiration for optimal pricing. (Developer Tooling, Live)
