full primer →

Painters sign in with an email one-time code and get an embedded Hedera wallet — no seed phrase, no extension, no gas estimator — and their collaborative painting actions settle in about three seconds for a fixed sub-cent fee.

Why this primitiveMagic Link email sign-in plus Hedera's fixed sub-cent fees allow smooth collaboration without gas friction or complex wallets.

Drives the UI as
a one-tap 'Sign in with email' that drops the user in with their 0.0.x account id and EVM address already on screen, plus HBAR/USDC balances and faucet links
