What we built
OPN Savings Vault is a simple DeFi vault deployed on OPN Chain. It lets a user deposit native OPN into a personal savings record, while the contract stores the deposit amount, creation time, and withdrawal status on-chain.
The goal is to create a small financial primitive that can later grow into a savings dashboard, deposit tracker, basic vault interface, or personal treasury tool.
Why
A lot of DeFi products begin with simple deposit and accounting logic. This build focuses on that foundation: transparent deposits, clear user records, and readable on-chain activity.
The contract is intentionally lightweight so reviewers can easily inspect the logic and confirm how funds are recorded.
How it works
- The user calls
deposit()and sends native OPN. - The contract creates a savings entry for that wallet.
- Each entry stores amount, timestamp, and withdrawal status.
- The user can read their savings count and individual saving records.
- The contract also includes a withdraw function for closing a saved position.
OPN Chain usage
The contract was deployed directly on OPN Chain during the Season 1 window. A live deposit() transaction was executed to prove interaction with the deployed contract.
