Suho 수호

What is Suho ​

Suho is a guardian wallet on GIWA Sepolia. It puts identity at the center of every payment. You send to names, not addresses. The wallet tells you who you are paying. You recover a lost device without a seed phrase.

The name is Korean. 수호 means to guard or protect. The visual language is Korean-modern: warm paper, ink text, one red seal.

What it does ​

  • Send to names. Type a up.id name. Suho resolves it on chain and shows a red seal if the recipient is a verified human.
  • Warn on strangers. An unverified recipient shows an amber warning. Small sends still go through. Large sends stop for an explicit hold-to-confirm, then your passkey — no code, just deliberate friction plus the key that already authorizes the exact transfer.
  • Recover with Arise. Lost your device? Rotate to a new passkey with a single-use code. Your address and name stay the same.
  • Carry a Card. An attested identity card, signed by your own account, with a walkable version history on EAS.

What makes it different ​

Your account is a passkey-controlled smart account at your own address. There is no seed phrase. Day to day, a passkey signs every transaction. A guardian service relays those transactions and pays the gas. It never sees a private key.

New users start from nothing. A fresh browser becomes a verified, named account in a few taps. The one-time key that bootstraps the account is generated in the browser, used to sign twice, and destroyed. See Custody and threat model.
