Cliff mechanics reduce the concentration of unlock events in the 90-day post-TGE window. On-chain enforcement means the schedule cannot be modified unilaterally after deployment.
Apply to Use Vesting ToolsThe standard configuration: 6-month cliff followed by 18-month linear unlock. All parameters are configurable within defined ranges at listing time.
No tokens are released during the cliff period. The clock starts at TGE. The default cliff is 6 months. For team and advisor allocations, a minimum 6-month cliff is required. Public sale allocations may use a shorter cliff (3 months minimum) or no cliff, depending on project structure.
After the cliff, tokens unlock linearly over the configured unlock period (default 18 months). Each month, 1/18 of the remaining locked allocation becomes claimable. The beneficiary initiates claims — tokens do not transfer automatically.
Based on secondary-market patterns observed across comparable TON ecosystem launches, projects that deploy cliff-locked vesting for team and investor allocations show measurably lower 90-day post-TGE sell volume compared to projects that use immediate linear unlock from TGE.
The mechanism is straightforward: immediate linear unlock from TGE means a significant portion of team and investor tokens become liquid on the same day as the public sale allocation. Early holders who received tokens at a deep discount have immediate incentive to partially exit. The cliff prevents this concentration of sell-eligible supply in the highest-volatility post-TGE window.
This does not eliminate sell pressure — once the cliff ends, tokens begin unlocking. But spreading unlock over 18 months at 1/18 per month reduces the impact of any single unlock event on secondary-market liquidity.
| Period | Cliff + Linear | Immediate Linear |
|---|---|---|
| Month 1–6 | 0% liquid | ~33% liquid |
| Month 7 | ~5.5% liquid | ~39% liquid |
| Month 12 | ~33% liquid | ~67% liquid |
| Month 24 | 100% liquid | 100% liquid |

Vesting schedules are configured during the listing process and written to the smart contract before TGE. Parameters cannot be changed after contract deployment.
| Parameter | Configurable Range | Default | Notes |
|---|---|---|---|
| Cliff Duration | 3–12 months | 6 months | Team/advisor allocations: minimum 6 months. Public sale: minimum 3 months (or 0 for public if project elects). |
| Total Unlock Period | 12–36 months (post-cliff) | 18 months | Linear unlock period begins immediately after cliff ends. |
| Team Schedule | Separate contract | Team vesting is a separate contract from investor and public sale vesting. Different cliff/unlock periods may apply. | |
| Advisor Schedule | Separate contract | Each advisor may have an individually configured schedule within the agreed parameters. | |
| Enforcement | On-chain only | Smart contract logic enforces the schedule. Tonstarter does not hold or control vested tokens and has no ability to modify schedules post-deployment. | |
