Gate

The site sits behind a separate gate during testnet: the first time you open it, you're sent to /gate/ and need an invite code issued by the team. Enter the correct code and a signed cookie is set for the whole domain; after that both the site and the API open without logging in again. The invite code is not in this handbook — ask the team if you need it.

This handbook is public

The docs at docs.mochi.meme are not behind the gate, so don't put invite codes or private keys here.

An account is a passkey

No email, no password. Each account is a passkey (WebAuthn):

• The key is created on your own device (Touch ID, Windows Hello, security key).
• From the passkey, the client derives a deterministic wallet, used to sign transactions.
• The domain is pinned to mochi.meme. Changing domains makes every old account inaccessible, so treat it as fixed.

Since rpId is part of the key, create accounts on the correct mochi.meme. An account created on a temporary host cannot be carried over.

Address and name

An account can be referenced in two ways:

• Address 0x… — always exists, never changes.
• Handle alice — a 3–21 character string, only lowercase letters, digits and _. The client limits display to 15 characters. The narrow alphabet is intentional: uppercase and lookalike characters are where impersonation starts.

Renaming returns the old name in the same transaction, so no one can hold two names and no name gets stuck.

Gas

Posting, voting, and creating communities are all on-chain transactions, so they need MON. Deposit MON from any wallet you control: your profile shows the account address and a QR code to send to, and Withdraw sends MON back out to an address you name. Everything here is gas — no server pays on your behalf.

If your account runs out of MON midway, the transaction won't go through; top it up from the same screen.
