Description

What the builder said.

Written by the team, rendered as the markdown they typed in the submission wizard.

What we built

OPN Locker — a trustless token locking contract for OPN Chain. Users can lock any ERC-20 token for a specified time period. Funds are locked on-chain and can only be withdrawn by the original owner after the unlock time passes.

Why

DeFi projects need reliable vesting and locking mechanics. Team token locks, LP locks, and vesting schedules are essential infrastructure for any serious project. OPN Locker provides this as a permissionless, trustless primitive on OPN Chain.

How it works

  • User calls lockTokens() with token address, amount, and unlock timestamp
  • Tokens are transferred to the contract and locked
  • After unlock time passes, owner calls withdraw() to get tokens back
  • Every lock has a unique ID and is stored on-chain
  • Full event history for transparency
