# What is a Facilitator?

> Introduction to facilitators and the Corbits facilitator

## What is a Facilitator?

A **facilitator** is a payment settlement server that handles the blockchain-specific logic for validating and executing payments between clients and API providers. Facilitators are designed around an any-to-any model: in principle, any wallet on any chain can pay any provider on any chain. The Corbits facilitator supports a practical subset of that space — covering the chains and tokens most developers need.

## Corbits Facilitator

The Corbits facilitator is free, production-ready, and requires no configuration. Point your resource server at it and payments work.

### Supported Chains and Tokens

| Network      | Environment  | Token |
| ------------ | ------------ | ----- |
| Solana       | devnet       | USDC  |
| Solana       | mainnet-beta | USDC  |
| Base         | mainnet      | USDC  |
| Base Sepolia | testnet      | USDC  |
| SKALE Europa | mainnet      | USDC  |
| Polygon      | mainnet      | USDC  |
| Monad        | testnet      | USDC  |

## Need More Flexibility?

If you need a chain or token combination that the Corbits facilitator doesn't support, you can deploy your own facilitator using [Faremeter](https://docs.faremeter.xyz/concepts/facilitators) — a self-hosted facilitator implementation built for any-to-any coverage. See the [Faremeter self-hosted setup guide](https://docs.faremeter.xyz/server/facilitator) to get started.

***

Most users won't need to think about any of this. The Corbits facilitator handles payment settlement automatically when you use the Corbits SDK or middleware.
