HOW IT WORKS
Our Gasless Authentication Architecture
A modular, secure system designed to eliminate user friction and transaction costs. We provide the complete backend infrastructure, so your team can focus on building the product.
01
Meta-Transaction Relayer
Our managed relay network signs and broadcasts user-signed messages, paying gas fees on their behalf. Includes automatic nonce management, gas price optimization, and failover routing for 99.9% uptime.

02
Smart Contract Wallet Proxy
Deploy ERC-4337-compatible Account Abstraction (AA) smart contract wallets. Users get social recovery, batch transactions, and session keys, all without managing seed phrases or gas.

Signature Verification & Security
Enterprise-grade signature validation using EIP-712 structured data. We implement replay protection, domain separation, and integrate with OpenZeppelin's EIP712 and SignatureChecker libraries.

Gas Sponsorship & Policy Engine
Define granular rules for who pays for gas (dApp, user, or hybrid). Set per-user, per-transaction, or subscription-based limits to control operational costs predictably.

CORE SERVICE
Smart Contract Development
Secure, gas-optimized smart contracts built by Web3-native engineers.
We architect and deploy production-grade smart contracts that power your protocol's core logic. Our development process is built on security-first principles, utilizing formal verification, comprehensive unit testing, and multi-audit cycles to mitigate risk before mainnet deployment.
Deliver a secure, auditable, and maintainable codebase that forms the trusted foundation of your decentralized application.
- Protocol-Specific Logic: Custom
ERC-20,ERC-721, staking mechanisms, governance modules, and bespoke DeFi primitives. - Gas Optimization: Expert-level Solidity development focused on minimizing transaction costs for end-users.
- Full Audit Support: Preparation for and remediation of findings from top firms like CertiK and OpenZeppelin.
- Deployment & Verification: Mainnet deployment with full source code verification on Etherscan and comprehensive documentation.
For Technical Decision Makers
Gasless Authentication: Key Questions
Get clear, technical answers to the most common questions about implementing gasless transaction authentication for your Web3 application.
We deploy a custom, audited smart contract wallet factory for your project. Users sign off-chain messages (EIP-712) with their private keys, which our relayer network validates and submits to the blockchain, paying gas fees on their behalf. This abstracts away gas complexity while maintaining non-custodial security. We support both batch transactions and single operations.
