Contract Deployment Script

WHAT IT DOES

Contract Deployment Script is a developer tool that generates deployment scripts for Hardhat, Truffle, and Foundry from your contract's ABI, bytecode, and constructor parameters. Enter the contract name, paste the ABI and bytecode, provide constructor parameters, and select the target network — the tool generates ready-to-use deployment scripts for each framework. It also simulates the deployment, displaying a deployment address and gas usage estimate. This is essential for developers preparing contracts for deployment, generating migration files, or switching between development frameworks.

HOW TO USE

Connect your wallet using the BGWallet bridge (MetaMask or any Web3 wallet). Enter the contract name — this will be used in the generated scripts. Paste the contract's ABI as a JSON array and the bytecode as a hex string (starting with 0x). Enter constructor parameters as a JSON array (e.g., [1000000] for a token with initial supply). Select the target network — Mainnet, Sepolia, Goerli, or Localhost. Click "Generate script" to produce the deployment scripts. Results display the contract name, generation status, network, a simulated deployment address, estimated gas used, and three scripts: a Hardhat deployment script (deploy.js), a Truffle migration (2_deploy_contract.js), and a Foundry script (Deploy.s.sol). You can copy any script directly into your project.

TECHNICAL MECHANISM

The tool generates deployment scripts using templates for each framework. For Hardhat, it creates a deploy.js script that uses hre.ethers.getContractFactory() and contract.deploy() with the provided constructor parameters. For Truffle, it generates a migration file that uses artifacts.require() and deployer.deploy(). For Foundry, it creates a Solidity script that uses forge-std/Script.sol and vm.startBroadcast() to deploy the contract. The tool also simulates deployment by generating a deterministic-looking contract address and estimating gas usage based on the bytecode size. The constructor parameters are formatted appropriately for each framework's syntax. All operations are performed client-side — no data is stored or transmitted. The generated scripts are ready to be copied and executed in a development environment with the corresponding framework installed.

WHAT IT CANNOT SEE

The tool cannot actually deploy contracts without a real wallet and network connection — the deployment is simulated. It cannot verify deployed contracts on block explorers — verification requires additional tools and API keys. It cannot handle complex deployment scenarios (e.g., factory contracts, proxy patterns, multi-sig deployments) without additional configuration. It cannot manage deployment dependencies or ordering — the generated scripts are standalone. It cannot simulate deployment failures accurately — the simulation always succeeds. It cannot validate that the ABI matches the bytecode — the tool assumes they are compatible. It cannot deploy to multiple networks simultaneously. The tool is read-only and does not sign any transactions.

PLEASE NOTE

This tool works exclusively with EVM-compatible chains for the wallet connection, but the generated scripts are chain-agnostic and work with any EVM project. Solana, Tron, Starknet, SUI, TON, Aptos, Bitcoin, Cosmos, and XRP are not supported for wallet connection but the script generation works regardless. The generated scripts are templates — review them before running. The tool does not store any data — all operations are performed client-side. The tool is provided as-is with no warranty or liability. Always test deployment scripts on a testnet before mainnet deployment.
