# Supported Chains

> Chains connected to AggLayer: chain IDs, rollup IDs, RPC endpoints, block explorers, and gas tokens.

## Overview

The following chains are connected to AggLayer. Each chain has a unique rollup ID assigned during registration.

Chain types:

* **PP (Pessimistic Proof)**: Sovereign mode secured by pessimistic proofs. No ZK prover required.
* **Validium**: ZK-secured execution with offchain data availability.
* **zkEVM**: Fully onchain ZK rollup.
* **ALGateway**: Connected through the AggLayer Gateway.
* **Outpost**: Non-CDK chain connected to AggLayer.
