Description

What the builder said.
Written by the team, rendered as the markdown they typed in the submission wizard.
What we built
FlowVault is a simple decentralized vault smart contract built on OPN Network.
Users can:
- Deposit funds into the vault
- Track their individual balances on-chain
- Withdraw available balances securely
- Interact without intermediaries
The contract is designed to demonstrate transparent asset management using Solidity.
Why
Traditional financial systems require trust in centralized services.
FlowVault explores a lightweight on-chain vault model where users maintain direct ownership and can verify balances and transactions publicly.
How it works
- Users call the deposit() function and send funds to the contract.
- Deposited value is recorded to the user's balance.
- Users can check holdings using myBalance().
- Users withdraw funds through withdraw(amount).
