Web and tech · delivered in 1-3 days
A fully secure, production-ready token vesting smart contract built for Ethereum, BSC and Polygon networks. It combines cliff and linear release logic with anti-reentrancy protection, and can include automated Python scripts to deploy and lock tokens safely and distribute them over time.
Distributing tokens fairly to a team, advisors or investors is one of the trickier parts of launching a Web3 project. Writing a dependable vesting mechanism from the ground up, then testing it properly, takes real time and care. This package gives you a finished, audit-ready contract so you can set up a professional lock-up structure without starting from zero.
Whether you are preparing an ERC-20 launch or running a DAO treasury, this contract is built to release tokens fairly and predictably over an agreed schedule.
The contract is built primarily for ERC-20 tokens and works across Ethereum, BSC (BEP-20), Polygon and other EVM-based networks.
You receive complete ownership of the delivered code, with no further fees attached. It has not been reviewed by an external audit firm, but it has been tested thoroughly in a local Ganache environment and follows established security conventions, so it is in a suitable state to be submitted to a third-party auditor before any mainnet deployment.
1. We confirm your token details and the vesting schedule you need, including cliff length and duration.
2. We prepare the smart contract, and where applicable the Python deployment scripts, to match your project.
3. We run a complete local simulation to confirm the vesting and release functions behave as intended.
4. You receive the finished source code, any scripts, and the full documentation.
This service suits founders and developers who need a tested way to lock and release tokens for a team, advisors or investors, whether you prefer to deploy the contract yourself, want local testing included, or need a custom schedule deployed to a testnet with direct support. Before ordering, have your project domain and a short brief ready, including your preferred vesting terms.
Your order opens its own thread here the moment it is paid, and everything about that order - questions, changes and the final report - happens in it.
The cliff is a fixed initial period during which no tokens can be withdrawn. After it ends, the remaining tokens unlock gradually over the agreed vesting duration. This two-stage approach is a common way to handle fair, gradual distribution to teams and investors.
Yes, the contract works with any standard ERC-20 token. You can set your own cliff length, vesting duration and beneficiary addresses for each grant. With the Premium package we also configure and deploy the custom schedule for you.
Not yet by an external firm, but it has been tested extensively in a local Ganache environment and built following standard safety practices such as nonReentrant protections and safe transfer handling. The code is clean, well documented and ready to be handed to a third-party auditor before you deploy to mainnet.
