Vesting Contract Generator

WHAT IT DOES

Vesting Contract Generator gives developers and project teams a streamlined way to deploy custom token vesting contracts using a factory pattern. It reads factory contract state, deployed vesting contract addresses, token configuration, deployment parameters, and chain state for gas estimation. You can deploy new vesting contracts with fully customizable parameters including beneficiary address, token address, total vested amount, cliff duration, vesting duration, and start time. The tool estimates gas costs before deployment, shows you the deployed contract address after confirmation, and provides transaction explorer links. Instead of manually writing and deploying vesting contracts for each beneficiary, you use a factory that handles the deployment logic, reducing errors and saving time.

HOW TO USE

Connect your EVM wallet. Enter the vesting factory contract address, token address, and beneficiary address you want to create a vesting schedule for. Set the total amount to vest (in human-readable units), cliff duration in seconds (e.g., 2592000 for 30 days), vesting duration in seconds (e.g., 15552000 for 180 days), and optionally a start time as a Unix timestamp or 0 to start immediately. Use "Estimate gas" to see the expected gas cost before committing. Click "Deploy vesting contract" to deploy a new vesting contract—this requires the factory contract to have allowance for the tokens. After confirmation, the tool displays the deployed contract address and links to the explorer. The generated contract supports release, revoke, and schedule viewing functions as implemented by the factory.

TECHNICAL APPROACH

This tool uses a factory contract pattern to deploy vesting contracts, avoiding the need to write and deploy each contract individually. It calls deployVesting() on the factory with all vesting parameters, which deploys a new proxy or full contract instance via CREATE2 or standard deployment. The tool queries the factory's state using ethers v5.7.2, reads deployed contract addresses from events, and estimates gas using estimateGas.deployVesting() to provide cost transparency before transaction submission. All RPC calls are wrapped in a robust error handler that extracts the actual failure reason from Ethers error objects, digging three levels deep to avoid showing "[object Object]" when a transaction reverts. For transaction costing, it uses receipt.effectiveGasPrice post-EIP-1559 rather than tx.gasPrice, which overstates actual spend. The tool also checks token balance and allowance before deployment, providing clear error messages for insufficient funds or approvals, and converts human-readable amounts to the correct decimals based on the token's decimals() call.

WHAT IT CANNOT SEE

This tool cannot verify the security or correctness of the generated vesting contract code, nor guarantee that the deployed contract will function as expected in all edge cases. It cannot audit the factory implementation or ensure that the vesting contract follows best practices. It cannot detect whether the factory contract has been tampered with or deployed with malicious intent. It cannot simulate execution or test vesting schedules before deployment. The tool deploys contracts based on the factory's implementation, but it does not guarantee that the factory is secure or that the deployed contracts will behave as intended. Users must verify the factory contract code and audit reports independently.

PLEASE NOTE

This tool supports EVM‑compatible chains only (Ethereum, Goerli, Sepolia, Arbitrum, Optimism, Polygon). Solana, Tron, Starknet, SUI, TON, Aptos, Bitcoin, Cosmos, and XRP are not supported. This is a read‑write tool that requires signing transactions—always verify the factory contract address, token address, beneficiary address, and all vesting parameters before approving. No contract addresses are hardcoded; you paste the factory contract you are using, so you are responsible for verifying its safety and ensuring it implements the expected vesting deployment interface. The tool is free and open under the BotGentz PLAYBOOK‑C specification.
