A crypto piggy bank you can't break early

usdtimelock.com is a digital piggy bank for USDC, USDT and POL on the Polygon network. You choose the release date, deposit your funds, and the smart contract does the rest — just like a real piggy bank, nothing comes out before it's time.

Why a crypto piggy bank works better than willpower

• Funds are locked by code, not by promises — no "just this once" withdrawals.
• Non-custodial: your keys, your coins. Nobody but the beneficiary you set can ever withdraw.
• Works with USDC, USDT and POL, all in the same free, open-source tool.
• No app to install — it runs entirely in your browser.

How it works

Open the app, connect a wallet (MetaMask, Trust Wallet or Coinbase Wallet), pick an amount and an unlock date, and confirm. Your piggy bank is now a smart contract on Polygon — track it anytime from the Monitor tab, top it up whenever you like, and withdraw once the date arrives.
