# OpenOcean > Best swap returns for decentralized crypto trading OpenOcean is a decentralized exchange aggregator. It routes trades non-custodially across multiple blockchains and liquidity sources for the best available prices with no protocol fees. OpenOcean is a decentralized exchange aggregator that gives crypto traders access to liquidity across multiple blockchains. It routes swap orders through a pathfinding engine that compares many possible paths to find the best available price. The service is aimed at retail traders, decentralized finance protocols, trading bots, wallet providers, and AI agents. The platform aggregates liquidity from automated market makers, request-for-quote providers, and other sources, and splits large orders across multiple venues when doing so improves execution. Swaps settle directly between a user's wallet and the destination address, so the protocol never takes custody of funds, and it charges no protocol fee. Its smart contracts are open source. Products include cross-chain swaps, perpetual trading, limit orders, dollar-cost averaging, a yield aggregator, and a campaign platform that rewards trading activity. For developers there is an API, an SDK, an embeddable widget, an MCP server, and agent skills that let AI agents fetch quotes and build swap transactions. - Type: Protocol - Sector: DeFi - Status: Active - Founded: 2021-12-01 - Profile: https://thegrid.id/profiles/openocean ## Products - [OpenOcean DEX Aggregator](https://thegrid.id/profiles/openocean): OpenOcean DEX Aggregator is a decentralized exchange aggregator that routes trades across a wide range of liquidity sources on multiple blockchains.

(DEX Aggregator, Live, Main Product) - [OpenOcean Cross-chain Swaps](https://thegrid.id/profiles/openocean): OpenOcean Cross-chain Swaps is a bridge aggregator for one-click asset transfers between blockchains. It compares routes across multiple bridge protocols to pick the path with the lowest cost and fastest transfer. The service runs on its own interface separate from the main trading application. (Bridge Aggregator, Live) - [OpenOcean Perpetual Trading](https://thegrid.id/profiles/openocean): OpenOcean Perpetual Trading is a perpetual futures aggregator for opening long or short leveraged positions on tokens. It routes orders to decentralized derivatives venues rather than matching trades itself, giving users one access point for margin trading. The product runs on its own subdomain separate from the spot swap application. (Decentralized Derivative Exchange, Live) - [OpenOcean Gasless Limit Orders](https://thegrid.id/profiles/openocean): OpenOcean Gasless Limit Orders lets users place limit orders that execute automatically at a target price without paying gas when the order is placed. Orders are recorded and filled through a dedicated onchain limit order protocol. The tool sits within the main trading app but uses its own smart contracts, separate from the swap router. (Decentralised Exchange, Live) - [OpenOcean Dollar Cost Averaging (DCA)](https://thegrid.id/profiles/openocean): OpenOcean DCA is a recurring-purchase tool that automates scheduled token buys to reduce timing risk. Users set an amount, frequency, and duration, and smart contracts execute the purchases onchain without further input. The feature has its own contract deployments and API alongside the main trading application.

It includes an API, an SDK, an embeddable widget, an MCP server for AI assistants, and agent skills. Developers use it to fetch quotes, build transaction data, and execute swaps on many chains without building their own routing engine. (Developer Tooling, Live) - [OpenOcean Campaigns](https://thegrid.id/profiles/openocean): OpenOcean Campaigns is a questing platform where users complete trading and engagement tasks to earn onchain rewards. It runs on its own subdomain and tracks task completion and reward distribution separately from the core trading application.
