Deploying Contracts on Abstract

Default: Foundry. Abstract uses the ZK Stack VM — contracts must be compiled with zksolc, not standard solc. For Hardhat, see references/hardhat.md. For EVM differences, see references/evm-differences.md.

Foundry Setup

1. Install foundry-zksync

curl -L https://raw.githubusercontent.com/matter-labs/foundry-zksync/main/install-foundry-zksync | bash
foundryup-zksync

Warning: This overwrites standard Foundry. Switch back with foundryup if needed.

2. Create project
