Builder funding record
OPN Grant Vault is a small on-chain grant funding primitive built on OPN Chain. The contract lets a user fund a grant-style vault with native OPN and creates a transparent record of that funding action.
Instead of trying to build a full grant platform in the first version, this build focuses on the core part: a funded grant entry that can be checked, counted, and later released.
What problem it addresses
Builder grants and ecosystem rewards often start as simple funding commitments. Teams need a clear way to show that funds were placed into a grant record, when it happened, and whether that grant entry is still active or already released.
This contract gives that basic record directly on-chain.
Core flow
A wallet calls fundGrant() and sends native OPN. The contract stores a grant entry with the funded amount, timestamp, and release status. It also tracks the total grant balance, grant event count, and grant amount by user.
The contract includes read functions so reviewers can inspect the grant records without relying on an external database.
Season 1 proof
The contract was deployed on OPN Chain during the Season 1 window. A live fundGrant() transaction was executed after deployment, so the submission includes both contract deployment and real on-chain usage.
Roadmap

What ships next.
The builder's own next-quarter plan. Use it to gauge follow-through and ambition.
Phase 1 — Submitted version
The current version keeps the grant logic intentionally simple:
- Deploy OPN Grant Vault on OPN Chain.
- Create a live grant funding record through
fundGrant(). - Store the funded amount, timestamp, and release status on-chain.
- Track total grant balance and grant event count.
- Keep grant data readable through view functions.
Phase 2 — Basic grant dashboard
The next step is to add a small front end around the contract:
- Connect wallet.
- Create a grant entry from the page.
- Show grant entries for the connected wallet.
- Display active and released grant records.
- Add explorer links for every grant transaction.
Phase 3 — More grant structure
After the basic dashboard, the project can support more realistic grant flows:
- Add named grant rounds.
- Add grant descriptions and funding categories.
- Add recipient addresses.
- Add ERC-20 support.
- Add public grant pages for transparent review.
Longer-term path
The long-term direction is to make OPN Grant Vault a lightweight builder funding tool for OPN Chain, where small grants, ecosystem rewards, and community funding records can be created and tracked transparently on-chain.
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.
