# Eco for solvers and market makers

> Quote and fulfill Eco intents, prove delivery, and collect the source-chain reward.

A solver quotes a requested outcome, fulfills it on the destination chain, and collects the source-chain reward after proof. Evaluate the reward against funding, execution, proof, and inventory costs before accepting an intent.

## Integration workflow

1. Implement the solver quote endpoints and register your service.
2. Monitor intent publication and confirm the reward is funded.
3. Fulfill the requested route on the destination chain.
4. Submit or wait for proof, then withdraw the eligible reward.

The [solver guide](/cookbook/become-a-solver) covers the published request schemas, registration requirements, and onchain lifecycle. The solver-facing interface is distinct from the integrator-facing v1 quote API.

## Plan liquidity and settlement

Cross-chain fulfillment can move your inventory between chains. Account for rebalancing and proof latency when pricing quotes. [Flash Intents](/routes/capabilities/flash-intents) provide a separate same-chain fulfillment path using the intent's own funds.

* [Routes architecture](/routes/architecture/overview) for contract roles.
