What we built
OPN Liquidity Note is a simple DeFi primitive deployed on OPN Chain. It lets a user create a native OPN liquidity note while the contract stores the amount, creation time, and removed status on-chain.
The goal is to model a lightweight liquidity record that can later be expanded into pool notes, liquidity tracking, basic LP dashboards, or transparent funding records.
Why
Liquidity tools often need clear records before more complex pool logic is added. This build focuses on the first layer: recording a funded liquidity note and making it readable on-chain.
The contract is intentionally small and easy to inspect, with straightforward deposit, tracking, and removal logic.
How it works
- The user calls
addLiquidityNote()and sends native OPN. - The contract creates a liquidity note for that wallet.
- Each note stores amount, timestamp, and removed status.
- The contract tracks total noted liquidity.
- The user can read note count and individual note details.
OPN Chain usage
The contract was deployed on OPN Chain during the Season 1 window. A live addLiquidityNote() transaction was executed to prove interaction with the deployed contract.
