Build focus
OPN Reserve Box is a reserve-tracking primitive deployed on OPN Chain. It allows a user to add native OPN into a reserve entry, while the contract records the amount, timestamp, and removal status on-chain.
This build is designed as a small treasury reserve layer rather than a full treasury app. The main goal is to keep reserve activity transparent and easy to verify.
Why it is useful
Reserve records are useful for teams, campaigns, community treasuries, grant pools, and simple risk-buffer tracking. A project may want to show that funds were added to a reserve and keep that action visible on-chain.
The contract keeps the flow minimal: add reserve, track totals, read records, and optionally remove a reserve entry later.
Contract logic
- The user calls
addReserve()and sends native OPN. - The contract creates a reserve entry for that wallet.
- Each entry stores amount, added time, and removal status.
- The contract tracks reserve amount by user.
- The contract also tracks total reserve balance and reserve event count.
- A removal function is included for closing a reserve entry.
OPN Chain proof
The contract was deployed on OPN Chain during the Season 1 window. A live addReserve() transaction was executed, so the submission includes both deployment proof and interaction proof.
Roadmap

What ships next.
The builder's own next-quarter plan. Use it to gauge follow-through and ambition.
Current version
The first version of OPN Reserve Box is focused on a simple reserve-tracking flow:
- Deploy the reserve box contract on OPN Chain.
- Test the
addReserve()function with native OPN. - Store reserve amount, added time, and removal status on-chain.
- Track reserve amount by user.
- Track total reserve balance and reserve event count.
- Submit the build for Season 1 review.
Next step
The next step is to turn the reserve flow into a small user-facing tool:
- Build a wallet-connected reserve page.
- Let users add reserve entries without using Remix.
- Show reserve history for the connected wallet.
- Display total reserve balance and reserve event count.
- Add explorer links for reserve transactions.
Product expansion
After the basic interface is ready, OPN Reserve Box can be expanded with:
- Named reserve boxes.
- ERC-20 reserve support.
- Reserve categories for treasury, grants, campaigns, and community funds.
- Public reserve pages for transparent tracking.
- Better event indexing for dashboards and analytics.
Long-term direction
The long-term goal is to create a lightweight reserve-management primitive for OPN Chain, where users, builders, and communities can keep transparent records of reserve funds, treasury buffers, and campaign allocations.
On-chain proof

1 contract on OPN Chain.
The chain itself confirmed every deployment is valid, signed by the builder's wallet, and inside the season's window.
