Token Vesting

Overview

Token vesting is a schedule or condition that gradually grants recipients transferable ownership or claimability over tokens allocated to them.

Vesting can use cliffs, linear release, milestones, performance, employment, governance, or smart-contract time locks and can apply to teams, investors, advisors, or communities. The process can change balances, supply, permissions, transferability, metadata, or future rights. The initiating authority, required approvals, timing, and reversibility determine whether the action is ordinary user behavior or a privileged administrative event.

Vested allocation, unlocked tokens, claimed tokens, and tokens actually sold are different states that should not be combined. Token Vesting should be tied to an exact asset, network, contract or mint, and implementation version. similar names can describe different mechanics, such as reducing total supply versus sending tokens to an inaccessible address.

Risks include hidden side agreements, revocable grants, contract bugs, accelerated release, governance changes, custody loss, insider concentration, and market unlock shocks. Risks include compromised authority, hidden or unlimited permissions, incorrect decimals, reentrancy or callback behavior, duplicated cross-chain supply, failed migrations, misleading event interpretation, and governance actions that alter prior assumptions.

Systems should record beneficiary, total grant, cliff, schedule, claimed amount, revocation, acceleration, contract, voting rights, transfer, and remaining locked balance. payment and custody systems should simulate or test unusual token behavior before support, including transfer fees, pauses, allowlists, rebases, callbacks, and upgradeable implementations. Exceptions need explicit reconciliation and refund rules.

Token Vesting, Token Distribution, and Token Claim may appear in the same workflow. Every component connected to Token Vesting should therefore be validated independently so a related asset or mechanism is not credited as the intended token.
