PolygonAlto bundler provides the essential components for ERC-4337 wallet development: bundlers that assemble and submit user operations, verifying paymasters that validate each operation, and ERC-20 paymasters that enable gas payments with ERC-20 tokens.
These tools work together to help you build wallets that are more stable and reliable while enabling faster iteration during development.
Use Alto bundler to streamline account abstraction work and explore gas-sponsorship patterns and user-initiated workflows.
