Account Abstraction for Device Wallets

Deploy ERC-4337-compliant smart contract accounts with embedded social recovery, multi-signature policies, and session keys. Built with OpenZeppelin libraries and audited for critical vulnerabilities.

Implement paymaster integrations so end-users never need native tokens. We handle gas fee sponsorship, meta-transactions, and batch operations to simplify the user experience.

Establish a persistent, non-custodial identity for each device across EVM chains (Ethereum, Polygon, Arbitrum). Enables seamless asset and data portability.

Integrate with TPMs, Secure Elements, and hardware wallets (Ledger, Trezor) for key generation and signing. Private keys never leave the secure enclave.

Define and enforce transaction rules (spend limits, whitelisted contracts, time locks) at the smart account level. Updates via secure off-chain signatures.

Managed infrastructure for UserOperation bundling and mempool monitoring. Guaranteed 99.9% uptime SLA with multi-region redundancy for global device fleets.

Eliminate the friction of pre-funding wallets for users. We implement gas sponsorship and paymaster integrations, enabling seamless, cost-free onboarding for your device network.

Replace vulnerable private keys with social recovery, multi-sig, and hardware-backed signers. We build secure, recoverable wallets that meet enterprise security standards.

Aggregate thousands of micro-transactions from devices into single on-chain settlements. Our architecture reduces gas costs by over 90% for high-volume DePIN operations.

Leverage our pre-audited, modular AA smart contract libraries and SDKs. Deploy a production-ready device wallet infrastructure in weeks, not months.

Enable your devices to interact with multiple blockchains (EVM, Solana, Cosmos) from a single abstracted account. We build the interoperability layer for your DePIN.

Built-in transaction simulation, risk scoring, and immutable audit trails for every device action. Simplify regulatory reporting and operational oversight.

We design your Account Abstraction (ERC-4337) architecture, including custom Account, Paymaster, and Bundler logic. This includes gas optimization patterns and security-first design using OpenZeppelin libraries.

We integrate our AA logic with your secure hardware (TEE/SE) or mobile SDK. We handle key management, transaction signing, and user operation construction for a seamless embedded experience.

Every module undergoes rigorous testing, including unit/integration tests and a formal security review. We provide a final audit report to ensure your system's integrity before mainnet deployment.

We manage the deployment of factory contracts, paymasters, and monitoring infrastructure. Includes 30 days of post-launch support to ensure stability and handle any integration nuances.
