Reservoir Protocol, the Cross-Chain Liquidity Engine for Web3

As the blockchain ecosystem expands, developers and users are increasingly challenged by fragmentation. Tokens, NFTs and liquidity pools are spread across dozens of chains like @ethereum, @0xPolygon, @solana or @arbitrum, making interoperability both complex and costly.

@reservoir0x Protocol addresses this pain point by creating a unified cross-chain liquidity infrastructure, designed to make every token on every chain tradable. Whether you're building a DeFi app, NFT marketplace or wallet, Reservoir provides the backbone for frictionless token trading in a multichain world.

How Reservoir Relay Unlocks Instant Cross-Chain Swaps

At the core of Reservoir is @RelayProtocol, a high-performance cross-chain execution protocol. Traditional bridges are slow and expensive, relying on multi-party consensus and complex messaging systems. Relay introduces a relayer-based model where a third party instantly executes the user's intent on the destination chain using its own liquidity, then settles the transaction afterward.

The result is fast, gas-efficient, and composable cross-chain swaps, perfectly suited for NFT minting, paymasters, smart contract calls, or any onchain transaction. This model eliminates latency, reduces bridge costs by up to 90%, and unlocks previously impossible use cases such as cross-chain native minting or multi-token inputs for a single transaction.

Chain Abstraction: One UX, Any Blockchain

One of the most powerful features of Relay is its ability to abstract away blockchain complexity. For the end user, this means interacting with Web3 apps as if there was only one unified chain. Users can pay gas from one chain while executing on another, mint NFTs from a chain they've never used, or combine assets across chains in a single action.

For developers, Relay supports this abstraction through unified balances, smart account compatibility, and modular APIs that integrate easily into any dApp. The result is a seamless experience that feels like Web2, with all the power of Web3.

Build DEXs Anywhere with Reservoir Swap

Reservoir also powers decentralized exchanges with Reservoir Swap, a framework that offers production-ready DEX infrastructure for any EVM-compatible chain. Instead of forking DEXs, the team works directly with the Uniswap DAO to deploy official Uniswap V2 and V3 contracts on new chains.

These canonical deployments are supported by custom routing APIs, liquidity tooling, and soon, SDKs for fast integration. Any developer can launch a high-performance AMM with full Uniswap compatibility in days, while accessing tools for liquidity mining, analytics, and onchain pricing.

NFT Trading Without Borders: Reservoir NFT Toolkit

Reservoir isn't limited to tokens. Its NFT infrastructure enables true cross-chain trading and aggregation. Using Reservoir's APIs and front-end components (ReservoirKit), developers can build NFT marketplaces, embed trading flows in wallets or games, or integrate global liquidity into their apps.

The platform automatically aggregates listings and bids from @opensea, @LooksRare, @blur_io, and other marketplaces, offering best-price execution across chains. With native support for royalties, custom fees, and instant order matching, Reservoir simplifies NFT trading down to a few lines of code.

Towards a Decentralized Relay Network

While the current Relay infrastructure is operated by @reservoir0x for performance and reliability, the roadmap is heading towards full decentralization. A permissionless relayer network will allow anyone to run a Relay node, stake capital, and earn fees for executing cross-chain transactions.

This future architecture will preserve the speed and efficiency of today's system while offering censorship-resistance and open participation. Until then, Reservoir's relayer offers trusted execution with built-in refunds, liquidity management, and safety guarantees, allowing the ecosystem to scale securely in production.

Supporting 60+ Chains, Built to Scale with Web3

Reservoir Relay is already live on over 60 blockchains, including Ethereum, @base, @solana, @Bitcoin, @LineaBuild, @Optimism, @arbitrum, and many more. Thanks to its modular, permissionless architecture, adding a new chain requires nothing more than a relayer willing to support it.

This radically simplifies adoption and enables developers to access new ecosystems instantly. As new L2s, rollups, and appchains emerge, Reservoir is built to grow with the Web3 landscape, not slow it down.

Conclusion: Reservoir as the Backbone of Cross-Chain Composability

Reservoir is not just another bridge, but a foundational layer for the composable, multichain future of Web3. Whether you're building a wallet, NFT marketplace, DEX, or onchain game, Reservoir gives you the infrastructure to abstract complexity, aggregate liquidity, and offer experiences that feel truly seamless.

In a world where users don't want to think about what chain they're on, Reservoir makes every chain feel like one.
