StrictlySave lets you save USDC and DAI in named, time-locked vaults across Base, Polygon, Arbitrum, and BNB Chain. Each vault is a separate onchain savings goal with its own unlock date — ideal for travel funds, emergency buffers, or any goal you want to protect from impulse spending.

Create your vaultWhat is a USDC savings vault?
A savings vault is a smart-contract account you fund with USDC or DAI. You choose a name and unlock date at creation. The contract holds your stablecoins until that date — you can add more before unlock, but you cannot withdraw early. After unlock, you claim the full balance to your wallet.
This is non-custodial: StrictlySave never holds your keys or moves funds without your signature.
Who is it for?
- Crypto natives who want discipline, not another DeFi gamble
- Builders and freelancers saving for equipment or taxes
- Anyone on Base or L2s who already holds USDC or DAI
- People who tried "just don't spend it" and failed
How it compares
vs. a bank savings account
Banks can be reversed or accessed early. StrictlySave vaults are enforced onchain — once locked, withdrawal waits until your date.
vs. a yield farm
Yield optimizes returns but does not stop you from withdrawing. A time lock optimizes discipline — the feature most savers actually need.
vs. holding USDC in your wallet
A wallet balance is one tap away from spending. A named vault with an unlock date creates friction on purpose.
Multichain by design
The same TimeLockVault contract is deployed on Base, Polygon, Arbitrum, and BNB Chain. Pick the network where you already hold stablecoins and pay the lowest gas for your habits. Switch networks in the app before creating or managing vaults.

Common questions
What is StrictlySave?
StrictlySave is a non-custodial stablecoin savings app on Base, Polygon, Arbitrum, and BNB Chain. You create named time-locked vaults, deposit USDC or DAI, add funds before unlock, and withdraw only after your chosen date. The smart contract enforces the lock — no early withdrawals.
Which stablecoins does StrictlySave support?
USDC and DAI on every supported network (Base, Polygon, Arbitrum, and BNB Chain). Each vault holds one stablecoin. Choose which one when you create the vault. We focus on stablecoins so your savings goal stays predictable in dollar terms.
Can I withdraw before my unlock date?
No. Vaults are strictly time-locked by the smart contract. Funds cannot be withdrawn until the unlock timestamp passes. There is no admin override and no early withdrawal option.
When exactly does my vault unlock?
Unlock happens at 11:59 PM on the date you select when creating the vault, in your local timezone. For example, if you pick June 21, withdrawal becomes available after 11:59 PM on June 21 — not at midnight at the start of that day.
Can I add more funds to an existing vault?
Yes. You can deposit additional USDC or DAI into the same vault anytime before the unlock date. You cannot add funds after the vault has unlocked or been withdrawn.
