What we built

OPN Reward Locker is a small DeFi primitive deployed on OPN Chain. It lets a user lock native OPN as a reward entry for a fixed period, while the contract records the amount, unlock time, and claim status on-chain.

The idea is to model a simple reward reserve that can later be used for community campaigns, contributor rewards, quest incentives, or delayed reward distribution.

Why

Community incentives often need transparent rules. A basic reward locker makes the process easier to verify because every reward lock is recorded on-chain and cannot be claimed before the unlock time.

This build keeps the logic simple and readable, focusing on deposit, time-lock, and claim mechanics.

How it works

  • The user calls lockReward() and sends native OPN.
  • The contract creates a reward lock for that wallet.
  • The reward unlock time is set automatically for 7 days.
  • The user can read reward count and reward details.
  • After the unlock time passes, the user can call claimReward().

OPN Chain usage

The contract was deployed on OPN Chain during the Season 1 window. A live lockReward() transaction was executed to prove direct interaction with the deployed contract.

  • Confirm that reward amount, unlock time, and claim status are stored on-chain.
  • Submit the build for Season 1 review.

Phase 2 - Campaign flow

  • Add a simple interface for creating reward locks.
  • Show active reward locks and claim status in a wallet dashboard.
  • Add explorer links for reward lock transactions.
  • Add clearer messages for locked and claimable rewards.

Phase 3 - Reward system upgrades

  • Add support for ERC-20 reward tokens.
  • Add named campaigns for community quests and contributor rewards.
  • Add admin-free public tracking pages for campaign transparency.
  • Improve event indexing for analytics.

Beyond
