# Introduction

> An intents-driven, permissionless, trust-neutral protocol for cross-chain transactions

# Welcome to Eco Routes

Eco Routes is an intents-driven, permissionless, trust-neutral protocol for facilitating the creation, incentivized execution, and proof of cross-chain transactions. Built with ERC-7683 compatibility, it supports multiple cross-chain messaging protocols including Hyperlane, LayerZero, Metalayer, and Polymer.

## What is Eco Routes?

Eco Routes enables users to express their desired outcomes on destination chains through **intents**. An intent represents your end goals - the calls you want to make, the resources needed, and the rewards you're willing to pay for execution.

The protocol connects three key participants:

  <Card title="Users" icon="user">
    Create cross-chain intents and escrow rewards for execution
  </Card>

  <Card title="Solvers" icon="robot">
    Execute intents on destination chains for fees
  </Card>

  <Card title="Provers" icon="shield-check">
    Verify intent fulfillment and enable reward settlement
  </Card>

## How it works

The Eco Routes protocol follows a simple flow:

<Steps>
  <Step title="Create an intent">
    Users define their desired cross-chain operations with specific parameters and escrow reward tokens in deterministic vaults.
  </Step>

  <Step title="Solver execution">
    Solvers monitor intents, marshall required resources, and fulfill the intent on the destination chain.
  </Step>

  <Step title="Proof verification">
    Provers verify that the intent was fulfilled correctly on the destination chain and relay proof back to the source chain.
  </Step>

  <Step title="Reward settlement">
    Once proven, solvers withdraw their rewards from the vault on the source chain.
  </Step>
</Steps>

<Note>
  Intents can be published on any chain, regardless of where input and output tokens live. You can even disseminate intent information directly to solvers without publishing to the Portal.

## ERC-7683 integration

Eco Routes implements [ERC-7683](https://eips.ethereum.org/EIPS/eip-7683), the standard for cross-chain order protocols. This enables:

* **Standardized interface**: Compatible with any ERC-7683 tooling and infrastructure
* **Ecosystem interoperability**: Works seamlessly with other intent-based protocols
* **Developer experience**: Familiar patterns for developers already using ERC-7683
* **Future-proof**: Built on an evolving standard for cross-chain transactions

Users can create and fulfill intents through both our native interface and the standardized ERC-7683 interface.
