Testnet Overview

The Lightchain AI Testnet is a fully functional replica of the mainnet environment, designed for developers to build, test, and iterate without risking real assets.
[!NOTE] Testnet tokens have no real-world value.
Use the testnet freely to experiment with smart contracts, validator setups, and dApp integrations.

Why Use the Testnet?

The testnet provides a safe environment to:
  • Deploy and debug smart contracts before going live on mainnet.
  • Test dApp integrations with the Lightchain AI ecosystem.
  • Experiment with Proof of Intelligence (PoI) consensus mechanics.
  • Validate gas estimation and transaction behavior.
  • Simulate AIVM interactions for on-chain AI inference workflows.

RPC endpoints may be rate-limited during periods of high demand. If you experience throttling, consider running your own testnet node.

Testnet Architecture

The Lightchain AI Testnet mirrors the mainnet architecture, including:
  • PoI Consensus — Validators earn rewards by contributing useful AI computations.
  • AIVM (AI Virtual Machine) — Execute on-chain AI inference tasks alongside standard EVM-compatible smart contracts.
  • Native Data Availability — Erasure-coded data availability layer with KZG commitments for cost-efficient blob storage.

Getting Started

Follow these guides in order to get up and running on the testnet:
  1. Connect to Testnet — Add the Lightchain AI Testnet to your wallet.
  2. Get Testnet Tokens — Claim free LCAI from the faucet.
  3. Deploy a Smart Contract — Deploy your first contract on the testnet.
  4. Interact with Contracts — Read and write to your deployed contracts.
  5. Verify a Contract — Verify your contract source code on the block explorer.
