Hey everyone,
We just open-sourced Klever Vesting – a complete token sale platform with built-in vesting for KleverChain. It’s MIT licensed and we’re looking for developers who want to build on it, fork it, or contribute.
What it does:
Token owners launch sales where purchased tokens are automatically locked in a smart contract and released over time. Buyers connect their Klever wallet, purchase tokens, and watch them unlock according to configurable schedules. Think of it as a launchpad with built-in vesting – no separate staking contract needed.
Key features:
- Configurable vesting schedules with cliff periods and linear unlock
- Early-exit penalty (configurable %) – users can leave early but forfeit a percentage
- Extension bonus – users who lock longer earn extra tokens (funded by early-exit penalties, creating a self-sustaining incentive loop)
- Multi-phase sales with different prices, caps, whitelists, and time windows
- Hardened security: user funds are protected on-chain (owner cannot drain vested tokens), two-step ownership transfer, schedule terms locked at purchase time
- 7 languages, dark/light theme, responsive design
Tech stack:
- Smart Contract: Rust / klever_sc 0.45.0 (KVM WASM) – 63 endpoints, ~35KB
- Frontend: SolidJS + Vite + TypeScript
- Backend API: Rust / Axum + PostgreSQL + Redis
- Event Listener: Rust / Tokio + WebSocket
The contract is deployed and tested on Klever testnet. The frontend reads live data from the chain. Everything compiles and works.
What we’re looking for:
- Frontend developers (SolidJS/TypeScript) – the UI works but could use more polish, charts, and animations
- Smart contract reviewers – extra eyes on the security model are always welcome
- Translation contributors – we have 7 languages but they could be improved, especially Japanese and Chinese
- Anyone interested in building on KleverChain
Links:
- GitHub: GitHub - Test0rMaik/Klever-Vesting: Token sale with configurable vesting on KleverChain · GitHub
- License: MIT (fork it, use it, build on it)
- Docs: 8 spec documents covering architecture, security model, deployment
Getting started is straightforward – clone, build the contract with cargo, run the frontend with npm run dev, point it at your testnet contract. Full instructions in the README.
