- WDK integration running on the Bare JavaScript runtime
- Multi-chain support across 10+ chains and assets
- Key management, transaction signing and recovery flows designed for mainstream users
The outcome
A reusable WDK-based custodial wallet layer that drops into new products in days, not months, hardening security while accelerating time-to-market.
