Builder-focused vault
OPN Builder Vault is a small ecosystem-funding primitive deployed on OPN Chain. It lets a user fund a builder-style vault with native OPN and creates a transparent on-chain record of that deposit.
The idea is to keep the first version focused on builder funding records rather than a full grant platform. It records value, time, wallet, and withdrawal status in a simple way.
Why this is relevant
Builder ecosystems often need lightweight funding tools: small vaults for contributors, campaign budgets, rewards, or early project support. Before adding complex roles or governance, the basic funding record should be easy to verify.
This contract provides that first layer directly on-chain.
Contract behavior
- The user calls
fundBuilderVault()and sends native OPN. - The contract creates a builder vault deposit for that wallet.
- Each deposit stores amount, deposit time, and withdrawal status.
- The contract tracks builder vault balance by user.
- It also tracks total builder vault value and deposit event count.
- A withdrawal function is included for closing a deposit later.
OPN Chain proof
The contract was deployed on OPN Chain during the Season 1 submission window. A live fundBuilderVault() transaction was executed after deployment, so the submission includes both deployment proof and real interaction proof.

What ships next.
The builder's own next-quarter plan. Use it to gauge follow-through and ambition.
Current build
This version of OPN Builder Vault focuses on a simple builder-funding record:
- Deploy the builder vault contract on OPN Chain.
- Test the
fundBuilderVault()function with native OPN. - Store deposit amount, deposit time, and withdrawal status on-chain.
- Track builder vault balance by user.
- Track total builder vault value and deposit event count.
- Submit the build for Season 1 review.
Next interface step
The next step is to make the builder vault usable from a small web interface:
- Add wallet connection.
- Let users fund a builder vault without using Remix.
- Show vault deposits for the connected wallet.
- Display active and withdrawn deposits separately.
- Add explorer links for builder vault transactions.
Product expansion
After the basic interface, the project can become more useful for ecosystem support:
- Add named builder vaults.
- Add vault categories such as grants, rewards, campaigns, or contributor support.
- Add ERC-20 vault support.
- Add public builder vault pages for transparent tracking.
- Improve event indexing for dashboards and analytics.
Long-term direction
The long-term goal is to make OPN Builder Vault a lightweight builder-funding primitive for OPN Chain, useful for ecosystem grants, contributor rewards, campaign budgets, and transparent project support records.
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.
