Cross-Chain Gas Abstraction Bridge Development

overview

CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built by Web3 specialists for your protocol or application.

We architect and deploy custom smart contracts that form the secure, immutable backbone of your application. Our development process is built on audited security patterns and gas-optimized code to ensure reliability and cost-efficiency from day one.

End-to-End Development: From initial design and Solidity 0.8+ coding to deployment on EVM-compatible chains.
Security-First Approach: Integration of OpenZeppelin libraries and comprehensive unit testing with Hardhat/Foundry.
Protocol-Specific Logic: Custom implementations for ERC-20, ERC-721, ERC-1155, staking, governance, and bespoke DeFi mechanics.

We deliver battle-tested contracts that reduce audit cycles and mitigate critical vulnerabilities before mainnet launch.

Our focus is on delivering a production-ready codebase within 2-4 weeks for an MVP, enabling you to move faster with confidence. We provide full documentation and handover, ensuring your team can maintain and extend the system.

ENGINEERED FOR SCALE

Core Architecture & Capabilities

Our bridge is built on a battle-tested, modular architecture designed to abstract gas complexity while ensuring security, speed, and developer control.

Unified Gas Abstraction Layer

End-users sign a single transaction on their origin chain. We handle all subsequent cross-chain gas payments, eliminating the need for users to hold native tokens on destination chains. This removes a major UX barrier for mainstream adoption.

User Signature

Destination Gas Tokens Needed

Modular Relayer Network

A decentralized network of permissioned relayers executes transactions across chains. The system uses a threshold signature scheme (TSS) for secure fund management and automated gas top-ups, ensuring 24/7 reliability without a single point of failure.

Smart Contract Audits & Security

All core bridge contracts undergo rigorous audits by leading firms like Trail of Bits and CertiK. We implement formal verification for critical logic and maintain a bug bounty program, providing enterprise-grade security for your users' assets.

Multi-Chain Gas Oracle

A real-time oracle system monitors and predicts gas prices across all supported EVM and non-EVM chains. This enables dynamic fee estimation and cost optimization, protecting your project from gas price volatility and failed transactions.

Developer SDK & APIs

Integrate gas abstraction in days, not months. Our TypeScript SDK and REST APIs provide simple methods for estimating costs, initiating transfers, and monitoring transaction status, abstracting away the underlying bridge complexity.

Custom Fee & Sponsorship Logic

Define who pays the gas: your application, the end-user, or a hybrid model. Implement custom sponsorship rules based on user tiers, transaction volume, or promotional campaigns directly through our management dashboard.

TANGIBLE RESULTS

Business Outcomes: Drive Adoption & Reduce Friction

Our cross-chain gas abstraction bridge delivers measurable business value by removing the primary barriers to user onboarding and transaction execution.

Zero-Friction User Onboarding

Users can interact with your dApp from any chain without holding native gas tokens. This eliminates the need for complex bridging tutorials and pre-funding wallets, directly increasing activation rates.

Frequently Asked Questions

Get clear answers on how our cross-chain bridge development service works, from timelines and costs to security and support.

Cross-chain gas abstraction allows users to pay transaction fees (gas) on a destination chain using tokens from a source chain. This eliminates the need for users to hold native tokens for every network, drastically improving UX and adoption. It's critical for applications targeting non-native users and for enabling seamless multi-chain interactions without friction.
