Rhinestone
Rhinestone is an SDK and intent engine for modular smart accounts that abstracts chains, bridging, and gas behind one signature.

What is Rhinestone?
Rhinestone gives wallet and app developers infrastructure for ERC-7579 modular smart accounts with built-in chain abstraction. A single API and TypeScript SDK handle account deployment, gas, and cross-chain intents across 12+ chains, while a module registry adds passkeys, session keys, social recovery, scheduled orders, and ZK email. Smart Sessions let users delegate scoped permissions to apps and agents for one-click multi-chain flows.
