Post a card · one transaction
Write the envelope. Once.
Everything on the envelope is the token's for good. Take your time with the picture and the line: they are what every explorer will read off the token, and what every holder will see above the sheet.
What one transaction does
SLOT 1
The envelope is written on
Name, ticker, picture, blurb and links go onto the token contract itself. contractURI is assembled from them on-chain and can never be changed.
SLOT 2
The position 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. No one can pull it.
SLOT 3
The sheet opens
From this transaction on, any wallet holding the card may press one stamp onto it. You get no more say over the sheet than anyone else.
