Two things you can do without spending anything
Search for a token address that ends in a word you chose, and turn a private invoice into a 32-byte memo that proves what a payment was for without telling anyone what it was for. Both run entirely in this tab.
Mine a token address
A B20 address is derived from your wallet and a number you pick, so you can search for one that spells something. This is not mining coins: nothing is minted, nothing is secured, and it costs nothing. It runs in this tab.
4 characters — around 65,536 tries on average.
Connect a wallet first — the address depends on who creates the token.
Build a private receipt
B20 transfers can carry 32 bytes. Put an invoice number there in plain text and everyone reading the chain knows what you bought. Put this hash there instead and nobody does — but you can prove it later to anyone, by showing the four fields it was made from.
Connect a wallet to build a commitment.
Keep the salt with the invoice. Without it the payment stays private from everyone — including you.
Making a token works today
Base makes the token, not us, so there was nothing to deploy first. The creation screen works the address out in your browser and runs the transaction against Base before you are allowed to sign it.
Everything on this page runs in your browser. Nothing is sent anywhere, and no transaction is made. Back to the market.
