BOTCHAIN ✦ BASE ✦ OPTIMISM ✦ ARBITRUM ✦ POLYGON ✦ ONE WALL PER CHAIN ✦

The small print, made big

A public wall with a very patient inbox.

  1. 01

    Choose your chain

    Five EVM networks, five parallel walls. Every visitor on a chain meets the exact same contract.

  2. 02

    Pick the moment

    Write up to 280 characters and set an unlock date. Your wallet seals it directly onchain.

  3. 03

    Let time pass

    The dapp keeps it covered until the chain clock says it is ready. Then it joins the open archive.
