There's no signup form because there's nothing to sign up for. Connect a Solana wallet, and from then on your device's own Face ID or fingerprint, a passkey, approves every contribution and withdrawal. Nothing to remember, nothing stored anywhere that could leak.
Phantom, Solflare, whatever you already have. This is the only thing resembling a login, and it's just a wallet you control.
Name it, set a USDC target. Your browser prompts for Face ID or a fingerprint once, that's your approval key from here on.
Share a one-time link. They connect their own wallet and register their own passkey on their own device, no key ever leaves either phone.
Either of you can add USDC anytime. Every contribution and withdrawal is approved with a face scan or fingerprint, and the balance comes straight from the chain.
Create a goal, register your passkey, invite someone. The whole flow takes under a minute.
