Build a saving habit onchain.

Create a personal saving challenge on Arc Testnet. Check in with daily USDC deposits and keep the right to withdraw your recorded principal whenever you choose. No yield, no custody, no lock-up.

Network gas: Separate, variable, network-controlled

No yield. No early-exit penalty.

Ownership

Your habit. Your wallet. Your principal.

ArcVault is a savings-habit tool, not a financial product. You deposit USDC from your own wallet into a contract you can verify. The contract records your principal — it never invests it.

Self-custodial

You interact through your own wallet. ArcVault never takes custody.

No yield, no investment

ArcVault records deposits. It does not invest, lend, or generate returns.

No custody, no lock-up

Your recorded principal is withdrawable. Not a bank, not a custody service.

How it works

A challenge with clear edges.

Choose a daily amount, required saving days, and a completion window. One valid daily deposit counts as that day’s check-in. Missing a day can end a streak without taking away your principal.

1
Create a goal
Choose the daily amount and duration before signing anything.
2
Deposit USDC
Approve and deposit once per UTC day. The contract — not your device clock — determines a valid day.
3
Monitor progress
Watch your streak, completed days, and recorded principal update from onchain reads.
4
Withdraw principal
Continue, complete, or withdraw all recorded principal and end the challenge. No penalty.
