Stake-note concept

OPN Stake Note is a minimal staking-record primitive deployed on OPN Chain. It lets a user create a stake note with native OPN and stores that note as a transparent on-chain record.

This is not a full staking protocol with rewards yet. It focuses on the accounting layer: how much was staked, when it was staked, and whether the note was later closed.

Why I built it this way

A lot of DeFi systems need stake-style records before reward logic is added. This contract separates the basic recordkeeping from future incentive mechanics, which makes the first version easier to audit and extend.

The result is a simple wallet-based staking note that can be checked directly from the contract.

Contract behavior

  • The user calls createStakeNote() and sends native OPN.
  • The contract creates a stake note for that wallet.
  • Each note stores amount, staking timestamp, and unstaked status.
  • The contract tracks total staked amount by user.
  • It also tracks total staked value and stake-note event count.
  • closeStakeNote() is included for closing a note later.

OPN Chain proof

The contract was deployed on OPN Chain during the Season 1 window. A live createStakeNote() 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.

Submitted version

This version of OPN Stake Note focuses on a clean staking-record layer:

  • Deploy the stake-note contract on OPN Chain.
  • Test the createStakeNote() function with native OPN.
  • Store stake amount, staking time, and unstaked status on-chain.
  • Track total staked amount by user.
  • Track total staked value and stake-note event count.
  • Submit the build for Season 1 review.

Next interface step

The next step is to wrap the contract with a simple user interface:

  • Add wallet connection.
  • Let users create a stake note from the page.
  • Show stake notes for the connected wallet.
  • Display open and closed notes separately.
  • Add explorer links for stake-note transactions.

Feature expansion

After the basic interface, the project can move toward more practical staking flows:

  • Add named stake notes.
  • Add optional staking periods.
  • Add ERC-20 stake-note support.
  • Add public stake pages for transparent verification.
  • Improve event indexing for dashboards.

Long-term direction

The long-term goal is to turn OPN Stake Note into a lightweight staking-record primitive for OPN Chain, useful for builder commitments, community staking experiments, reward planning, and transparent stake-style accounting.

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.
