The primitive.

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 generative art actions settle in about three seconds for a fixed sub-cent fee.

Why this primitiveHedera's fixed sub-cent fees plus embedded wallet offer frictionless deployment and sales for generative artists.

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
