Access record primitive

OPN Access Vault is a small access-accounting contract deployed on OPN Chain. It lets a wallet create an access-style deposit with native OPN and stores that record directly on-chain.

The first version is intentionally simple. It does not try to manage roles, subscriptions, or permissions yet. It focuses on the core proof layer: a wallet joined, value was deposited, the timestamp was saved, and the access record is still active unless revoked.

Why this matters

Many Web3 products need some kind of access record: gated tools, member areas, campaign participation, contributor groups, private testing, or builder programs.

Those records are often stored off-chain. This contract makes the base access event visible and verifiable on OPN Chain.

Contract flow

  • The user calls addAccessDeposit() and sends native OPN.
  • The contract creates an access deposit for that wallet.
  • Each record stores amount, join time, and revoked status.
  • The contract tracks access balance by user.
  • It also tracks total access balance and access event count.
  • revokeAccessDeposit() can close an access record later.
  • View functions expose access records by wallet.

OPN Chain proof

The contract was deployed on OPN Chain during the Season 1 submission window. A live addAccessDeposit() transaction was executed after deployment, so this submission includes both deployment proof and real interaction proof.

Roadmap

What ships next.

The builder's own next-quarter plan. Use it to gauge follow-through and ambition.

Current submission

This first version of OPN Access Vault keeps the access logic simple and verifiable:

  • Deploy the access vault contract on OPN Chain.
  • Test the addAccessDeposit() function with native OPN.
  • Store access amount, join time, and revoked status on-chain.
  • Track access balance by user.
  • Track total access balance and access event count.
  • Submit the build for Season 1 review.

Next step

The next step is to create a basic access dashboard:

  • Add wallet connection.
  • Let users create access deposits from a web page.
  • Show access records for the connected wallet.
  • Display active and revoked records separately.
  • Add explorer links for access transactions.

Product expansion

After the basic interface, the vault can support more access-focused use cases:

  • Add named access groups.
  • Add access categories for campaigns, private tools, testing groups, or builder programs.
  • Add optional access periods.
  • Add ERC-20 access deposits.
  • Add public access pages for transparent verification.

Long-term direction

The long-term goal is to turn OPN Access Vault into a lightweight access-record layer for OPN Chain, useful for gated communities, builder groups, campaign access, contributor programs, and transparent participation tracking.

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.
