Maelstrom / Farcaster onboarding

Create a Farcaster account with QR funding + auto registration

Generate a fresh seed phrase, scan the wallet QR from your phone, and as soon as funding lands on Optimism this page will try to register the FID automatically.

0) Import existing key + lookup account

Paste a seed phrase, private key, or backup JSON. We will derive custody address and load Farcaster account data (FID, onchain custody, recovery signer).

1) Generate seed phrase

This seed phrase controls the Farcaster custody wallet. The phrase never leaves your browser.

2) Fund by QR

Send OP ETH to this custody address from any wallet app. No browser wallet connection needed.

Recovery address (recommended: standard Farcaster recovery proxy)

Automatically try FID registration when funding is detected.
