Stamppad · a launchpad on Robinhood Chain · Uniswap v4

Dear holder, this is a launchpad where every token is a postcard. Its envelope, the name, the picture, the line about it and the links, is written onto the token itself and served from there, so nothing about it lives on a server that can go dark.

Every card carries a sheet. If you hold the card you may press one stamp onto it: a short line from your own key, dated, numbered in the order it arrived, kept on the chain for good. One per wallet. The sender who posted the card gets no say over the sheet, and a low number is proof you were there.

The pool's liquidity sits in the dead letter office before the first trade. Post a card to send one, or read the rack and press your stamp on someone else's.

Printed on the chain · no owner · no pause · no cap on any wallet

The rack

Cards on the rack.

— posted · newest first · market cap in ETH on the stamp

The post office opens soon.

When the contracts land on Robinhood Chain, every card posted here hangs on this rack, newest first.

How it is posted

One transaction, three slots.

SLOT 1

The envelope is written on

Name, ticker, picture, blurb and links go onto the token contract itself when it is posted. contractURI is assembled from them on-chain and can never be changed.

SLOT 2

The sheet is open to holders

Any wallet holding the card may press one stamp onto it: a short plain line, dated, numbered in order. One per wallet, ever. The sender has no say over it.

SLOT 3

The pool goes to the dead letter office

The pool's liquidity is minted as one Uniswap v4 position NFT owned by the dead address from its first block. Trades pay postage in ETH to the mailroom, inside the swap.

The dead letter office

The liquidity is a letter nobody can collect.

When a card is posted, the post office puts the pool's liquidity into a single Uniswap v4 position and mints that position's NFT straight to the dead address, in the same transaction. Nobody holds it. There is no owner on the post office, no pause, no admin key, no function that moves a position. You do not have to take that on trust: read the owner off the chain, here, for any card.
