Multi-Chain Signature Aggregation

We build systems that aggregate and verify user signatures across multiple blockchains into a single, verifiable proof. This enables unified application access and secure cross-chain actions without managing separate wallets or permissions.

overview
CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built by Web3-native engineers.

We deliver audit-ready code for ERC-20, ERC-721, and custom protocols, ensuring your tokenomics and business logic are flawlessly encoded. Our contracts are built on Solidity 0.8+ with OpenZeppelin standards and include comprehensive unit testing.

From initial concept to mainnet deployment, we manage the full lifecycle with a focus on security and gas optimization.

  • Custom Logic: DeFi mechanisms, governance systems, NFT utilities.
  • Security First: Formal verification and pre-audit reviews.
  • Full Deployment: Testnet validation, verification, and mainnet launch support.

PROVEN FRAMEWORK

Our Delivery Methodology

A structured, security-first approach to delivering production-ready multi-chain signature aggregation. We focus on predictable timelines, audited code, and seamless integration.

01

Architecture & Specification

We define your exact multi-chain requirements, select optimal protocols (EIP-4337, EIP-1271, MPC), and design a secure, gas-efficient architecture with clear technical specifications.

1-2 weeks
Design Phase

Frequently Asked Questions

Get clear, technical answers about our signature aggregation service, from security and integration to timelines and support.

A standard deployment, including smart contract development, integration with your existing frontend/backend, and initial testing, typically takes 3-5 weeks. Complex requirements, such as custom signer sets, novel cryptographic schemes, or support for more than 5 chains, can extend this to 6-8 weeks. We provide a detailed project plan with milestones after the initial scoping call.
