Validator

How to operate a Solver Node and participate in the EZYS network as a Validator.

Overview

A Validator operates a Solver Node — the unit that receives Intents, aggregates quotes from connected Liquidity Providers, evaluates candidates, and proposes the best execution path to the network.

Validators compete with each other. The Validator whose proposal offers the best rate for a given Intent wins the execution and earns a fee.

What a Validator Does

Responsibility	Description
Connect LPs	Manage adapter connections to one or more Liquidity Providers
Aggregate quotes	Fetch and merge quotes from connected LPs for each Intent
Evaluate	Score candidates and select the best one
Propose	Submit the winning candidate as a Solution to the network
Execute	If selected, coordinate the execution and settlement

How It Works

Intent arrives → Your Solver Node fetches quotes from your LPs
              → Evaluates and selects the best candidate
              → Submits proposal to the network
              → If your proposal wins → Execution proceeds at your quoted rate

Validator vs. Liquidity Provider

You can be one or both:

	Liquidity Provider	Validator
What you run	Adapter endpoint	Solver Node
What you do	Respond to quote requests	Aggregate, evaluate, propose
How you earn	Spread on your quotes	Execution fees on winning proposals
Can be combined	Yes — connect your own pricing as an LP to your own Solver Node

A common setup: an FX trading institution runs a Solver Node (Validator) with its own liquidity as one of the connected LPs, alongside third-party LPs.

Requirements

Requirement	Description
Infrastructure	Ability to run a Solver Node with reliable uptime
LP connections	At least one connected Liquidity Provider (can be your own)
Network access	Registered with the EZYS network

Economics

Validators earn execution fees when their proposals are selected. The more competitive your connected liquidity, the more often your proposals win.
