ERC-4337 at Shivacha
Account abstraction standard using UserOperations, bundlers and paymasters.
Overview
ERC-4337 implements account abstraction without protocol changes: users submit UserOperations to bundlers, an EntryPoint contract validates and executes them, and paymasters can sponsor gas. We implement smart accounts, paymasters and integrations with bundler infrastructure.
Why we use it
- No base-layer changes required
- Gas sponsorship
- Modular smart accounts
- Broad EVM support
