You use your existing wallet.
To get started, you connect a wallet to create your Machines Cash account. Your wallet proves who you are and signs actions, just like it does with any onchain app today.
Deposit
You connect your wallet and sign a transaction to move funds into Machines Cash. This is the same flow as connecting MetaMask to Uniswap or any other app. Your wallet stays in control. We never touch your keys.
Withdraw
When you withdraw, you connect your wallet again and sign a transaction to send funds to another address. Machines Cash cannot move money on its own. Your wallet must approve every withdrawal.
Machines Cash does not replace your wallet.
It uses your wallet to authorize deposits and withdrawals, while we handle spending, cards, and controls on top.
