Onboarding: Two Ways to Connect

Bullbit offers two distinct onboarding paths to cater to both new users and Web3 natives.

Option A: The "Invisible" SmartWallet (Recommended for New Users)

This flow utilizes the Full Account Abstraction stack to deliver a Web2-like experience.

A. The 30-Second Start (Registration)

1. User Action: Enter Email or use Social Login (Google/Gmail)

2. System Action: Calls Passkey API. User scans FaceID/TouchID.

3. Result: Account created. User enters the main interface immediately.

   1. Under the hood: We use CREATE2 to pre-calculate the AA Wallet address (Counterfactual Address).

   2. Lazy Deployment: The contract is NOT deployed immediately to save gas. It is deployed "just-in-time" along with the first deposit transaction.

B. Re-login (Trusted Device)

1. User Action: Open Bullbit App/Web.

2. System Action: Detects existing Passkey credential. Displays "Login as $$User Name$$"

3. User Action: Tap button -> Login successful.

   1. Under the hood: Client calls navigator.credentials.get() to check for local credentials. Server verifies the signature against the stored Public Key.

C. Adding a New Device (Visual Challenge)

Used when switching to a new phone or PC. Prevents phishing.

1. On New Device (Device B): Enter Email. System prompts setup. User scans FaceID to generate a new key pair. Screen displays a Matching Code (e.g., 58). Status: "Waiting for approval...".

2. On Old Device (Device A): Receives Push Notification. Asks: "What code is shown on the other device?" (Options: 24, 58, 99).

3. Approval: User selects 58 on Device A -> Confirms with FaceID.

4. Execution: Device B automatically logs in.

Option B: Standard Web3 Wallet (For DeFi Natives)

If you already possess a self-custodial wallet, you can connect directly without creating a Passkey account.

Connect Wallet

• Click "Connect Wallet" on the Bullbit homepage.

• Select your provider (MetaMask, Trust Wallet, SafePal, etc.).

• Sign the connection request in your wallet extension/app.

Once connected, your wallet address serves as your identity. You can immediately proceed to deposit funds.
