Smart Wallet and BSC Deployment

Signa uses a smart-wallet onboarding model to reduce setup friction for users while keeping trading and settlement on BSC.

Account flow

Email / External Wallet → Privy Smart Wallet → BSC Chain

↓

Dedicated account environment

• Deposit: funds are sent into the Signa smart wallet
• Withdraw: funds are sent out to a user-controlled address

Why this design?

This model allows Signa to abstract much of the operational friction that usually comes with on-chain products:

• Users can start with email or wallet login
• Routine actions do not require separate gas management from the user
• BSC provides relatively low transaction costs and broad wallet support

User experience implications

• No seed phrase management for email-first users
• Signature-based login for wallet users
• A consistent account structure across login methods
