Build concept

OPN Pledge Ledger is a commitment-record primitive deployed on OPN Chain. It lets a user make a native OPN pledge and stores that pledge as a transparent wallet-based record.

The purpose is to create a simple on-chain ledger for commitments, pledges, campaign support, or lightweight reserve promises.

Why it is useful

Many Web3 communities rely on pledges, commitments, and participation promises. These are often tracked off-chain in forms, chats, or dashboards.

This contract moves the basic pledge record on-chain. It stores who pledged, how much was pledged, when it happened, and whether the pledge was later released.

Contract behavior

  • The user calls makePledge() and sends native OPN.
  • The contract creates a pledge record for that wallet.
  • Each pledge stores amount, pledge timestamp, and release status.
  • The contract tracks total pledged amount by user.
  • The contract also tracks total pledged value and total pledge events.
  • A release function is included for closing a pledge entry.

OPN Chain proof

The contract was deployed on OPN Chain during the Season 1 window. A live makePledge() 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 Pledge Ledger focuses on a simple on-chain pledge record:

  • Deploy the pledge ledger contract on OPN Chain.
  • Test the makePledge() function with native OPN.
  • Store pledge amount, pledge time, and release status on-chain.
  • Track total pledged amount by user.
  • Track total pledged value and total pledge events.
  • Submit the build for Season 1 review.

Next step

The next step is to make pledges easier to create and view:

  • Build a wallet-connected pledge page.
  • Let users create a pledge without using Remix.
  • Show pledge history for the connected wallet.
  • Display active and released pledges separately.
  • Add explorer links for pledge transactions.

Product expansion

After the basic interface is ready, the pledge ledger can support more community use cases:

  • Add named pledge campaigns.
  • Add pledge descriptions and categories.
  • Add ERC-20 pledge support.
  • Add public campaign pages for transparent commitment tracking.
  • Improve event indexing for dashboards and analytics.

Long-term direction

The long-term goal is to create a lightweight commitment layer for OPN Chain, where users, builders, and communities can record transparent pledges, campaign support, and simple on-chain commitments.

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.
