ENGINEERED FOR DEPIN
Core Integration Capabilities
We deliver the foundational wallet infrastructure that powers your DePIN's user experience, from onboarding to complex device management. Our integrations are built for scale, security, and seamless operation.
01
ERC-4337 Smart Account Integration
Implement ERC-4337 standard for gasless transactions, batch operations, and session keys. Enables users to pay fees in any token and recover accounts via social logins, removing the #1 barrier to DePIN adoption.
