ONE BLOCK. ONE CITY. YOURS.

After the
last train.

A night city, drawn onchain. Walk its streets, ride the line out to the mountains,
and mint one block of it in the gallery.

作品 / THE COLLECTION

One block.
One night.

Every token is a six-second night drawn by the contract from the block it was minted in. You can’t choose it, and nobody can make it twice.

  1. 01

    Mint captures a moment

    Your transaction lands in one block on the chain. That block number becomes your token, and only the first mint in each block succeeds. There is nothing to pick and nothing to upload.

  2. 02

    The block becomes a seed

    The block’s own onchain information is hashed into a seed. It decides which night you get and everything inside it: the signs, which windows are lit, where the rain falls, the light and the rhythm.

  3. 03

    Drawn whenever it’s read

    No image is stored. The contract renders the animation in Solidity on every read and returns a lossless AVI, its player and a first-frame poster in the token’s metadata. Ask again in a decade and it draws the same night.

Eight kinds of night

Each seed falls into one of eight settings. Seven are equally likely; one is rare.

The original lossless AVI, drawn by the contract from this block. Its poster is the first frame.

概要 / A MOMENT, KEPT

The chain keeps moving.
Your night stays.

Minting captures the block your transaction lands in. Its own onchain information becomes a seed for one of eight animated worlds. No numbers to choose. No images to upload.

The art lives in the contract. Every pixel, colour and frame is generated in Solidity whenever it’s read. Your block becomes a six-second loop with its own data written across it: block number, gas, chain, parent and L1 hashes. Yours to keep.

Places

  • 地下鉄 Subway. Tap a ticket gate (改札) to connect your wallet, then ride the train to the mountains.
  • ギャラリー Gallery. Mint at the terminal (鋳造). Minted blocks hang on its walls.
  • ラーメン Ramen shop. Choose a free bowl at the ticket machine (食券機), eat at the counter and collect a bill. An ETH tip to the deployer is entirely optional.
  • 桜川 Sakuragawa. A riverside station among the cherry blossoms.

財布 Wallet. Use the wallet button at the top or a subway ticket gate. Connecting sends no transaction; you mint at the gallery terminal.

Glowing lines on the pavement mark doorways. The map in the corner shows where each place is.
