Contribution tracking layer

OPN Contribution Log is a small on-chain contribution record deployed on OPN Chain. It lets a wallet log a native OPN contribution and keeps the contribution amount, timestamp, and archive status directly in the contract.

This build is focused on transparency. Instead of tracking contributions only in off-chain spreadsheets, forms, or community tools, the basic record is written to OPN Chain.

What it is for

A contribution log can be useful for community pools, builder support, campaign funding, grant participation, or small ecosystem activity records. The contract does not try to solve every community finance problem at once. It creates the first layer: a simple wallet-based contribution history.

Contract flow

  • A user calls logContribution() and sends native OPN.
  • The contract creates a contribution entry for that wallet.
  • Each entry stores amount, contribution time, and archive status.
  • The contract tracks contribution amount by user.
  • It also tracks total contribution value and contribution event count.
  • archiveContribution() can close a contribution record later.
  • Read functions expose contribution history by wallet.

OPN Chain proof

The contract was deployed on OPN Chain during the Season 1 submission window. A live logContribution() transaction was executed after deployment, proving both deployment and real contract interaction.

Roadmap

What ships next.

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

Current build

The submitted version of OPN Contribution Log focuses on a transparent contribution record:

  • Deploy the contribution log contract on OPN Chain.
  • Test the logContribution() function with native OPN.
  • Store contribution amount, timestamp, and archive status on-chain.
  • Track contribution amount by user.
  • Track total contribution value and contribution event count.
  • Submit the build for Season 1 review.

Next step

The next step is to make contribution tracking easier from a basic interface:

  • Add wallet connection.
  • Let users log contributions from a web page.
  • Show contribution history for the connected wallet.
  • Display active and archived contributions separately.
  • Add explorer links for contribution transactions.

Product expansion

After the first interface, the project can support more community finance use cases:

  • Add named contribution campaigns.
  • Add contribution categories such as grants, rewards, campaigns, or builder support.
  • Add ERC-20 contribution support.
  • Add public contribution pages for transparent tracking.
  • Improve event indexing for dashboards and analytics.

Long-term direction

The long-term goal is to turn OPN Contribution Log into a lightweight contribution-record layer for OPN Chain, useful for community funding, builder support, grant participation, and transparent ecosystem activity.

On-chain proof

03/03

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.
