About this listing

Why a vesting contract matters

Fairly distributing tokens to a team, advisors or investors is a complex part of any Web3 launch. Building a dependable mechanism from scratch and testing it properly takes significant time. This package provides a finished, audit-ready contract to set up a professional lock-up structure immediately.

Whether you are preparing an ERC-20 launch or managing a DAO treasury, this contract releases tokens predictably according to an agreed schedule.

What you receive

  • A clean, gas-conscious and fully commented Solidity vesting contract
  • Full README documentation explaining configuration, deployment and usage on any EVM-compatible chain
  • A working demonstration confirming that the cliff period, linear release and withdrawal logic behave correctly
  • In the higher packages, a Python (Web3.py) script that handles compilation, deployment and local testing

Key features

  • Cliff and linear release: an initial lock-up period followed by a steady, time-based release of tokens
  • Reentrancy protection built in through a custom nonReentrant modifier
  • Owner controls for creating grants and revoking unvested tokens if needed
  • A vestedAmount view function so claimable balances can be checked at any time
  • Support for several concurrent grants, suited to teams, advisors or multiple investor rounds

Token standards and network support

The contract is built primarily for ERC-20 tokens and works across Ethereum, BSC (BEP-20), Polygon and other EVM-based networks.

Ownership and audit status

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.

How we work

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.

Who this suits

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.

Questions and answers

How does the cliff and linear release mechanism operate?

The cliff is a set initial period where no tokens can be withdrawn. Afterwards, remaining tokens unlock progressively over the agreed vesting duration, providing a reliable distribution method for teams and investors.

Can I apply this contract to my ERC-20 token and tailor the schedule?

Yes, the contract is compatible with any standard ERC-20 token. You can define your own cliff length, vesting duration and beneficiary addresses for each grant. The Premium package includes configuration and deployment of your custom schedule.

Has an external company audited this contract?

It has not been reviewed by an external firm yet, but it undergoes extensive testing in a local Ganache environment using standard safety practices like nonReentrant protections and safe transfer handling. The clean, documented code is ready for third-party auditing before mainnet deployment.

Are refunds available if I change my mind?

Because this is a digital source-code product, refunds are not provided after file delivery. Revisions are included to ensure the output meets your requirements: 1 revision for Basic, 2 for Standard, and 3 for Premium.
