MonthlyLock by 10102
Put a little aside every month, locked until a date you choose.
Buy on Coinbase, send it to your wallet, lock it. It opens on the day you pick, and nobody can open it earlier. Not even you.
Free to use. You pay only the Ethereum network fee.
Before you start
You need a wallet app, on your phone or in your computer's browser. If you use Coinbase, Coinbase Wallet works; MetaMask and Rainbow do too. Two minutes to install.
How it works
-
Let Coinbase buy for you
In the Coinbase app: Buy, then Recurring buy. Pick USDC if you want the value to stay steady, or ETH. Your bank money turns into USDC or ETH on its own.
-
Once a month, send it to your wallet
In the Coinbase app: Send, paste your wallet address and choose the Ethereum network, not any other. Your wallet address is shown on the Save page, with a code to scan and a copy button. Send a small amount the first time. Monthly, not weekly: every lock is a transaction on Ethereum with its own network fee.
-
Lock it
Open the Save page, pick the amount and the opening date: 1, 3, 5 or 10 years from now. Confirm in your wallet. Each month's lock opens on its own date.
What you should know
- No early withdrawal. A lock opens on its date and not a day sooner. Nobody can open it early, including us.
- No interest. You get back exactly what you put in.
- Not a bank account. No bank holds the money and no deposit protection covers it. It sits in an audited contract on Ethereum, in your name.
- Fees. Locking is a transaction, and so is taking it back. You pay the network fee for each, usually a few dollars.
More to know
- Prices move. ETH goes up and down. USDC is made to stay close to one dollar.
- The Save page asks for your wallet. Until you confirm, the money stays in your wallet app. When you confirm, it moves into the lock.
