Answer

The Bridge wallet creation process requires a single API call specifying the customer ID and blockchain. While there's no SDK, the API is designed to be simple with only a few endpoints needed. Bridge plans to add wallet creation capabilities to their dashboard in the future, but currently developers must either use the API directly or request assistance from Bridge's technical team. The wallets are custodial by default and abstract away crypto complexities like gas fees.

Wallets integrate with Bridge's broader infrastructure including virtual accounts, liquidation addresses and card issuance.

Bridge uses HD wallets for parallel processing of high-volume transactions. The system supports multiple wallets to handle high throughput, with each shard/wallet having a 1:1 relationship. Bridge can scale to hundreds of thousands or even millions of wallets, though wallets are currently limited to Base and Solana chains. The platform uses a "binary distribution" system for managing wallet value distribution and includes balance reservations and transit locks to prevent concurrent access issues. For high-transacting customers, Bridge can assign them to specific "high transacting" HD wallets.

Wallets can hold multiple stablecoins (currently USDC and USDB) on Base and Solana chains. They can receive and auto-convert funds from other chains/assets. Wallets integrate with fiat payment rails (ACH, wire, SEPA) for seamless on/off ramping. Users can deposit fiat that auto-converts to stablecoins.

Bridge Wallets support custom labels, permissions, and policies at the wallet level for secure transactions and management.
