overview

FULL-STACK INFRASTRUCTURE

Custom Blockchain Development

Build, deploy, and scale custom blockchain networks and applications tailored to your business logic.

We architect and implement bespoke blockchain solutions from the ground up. Our full-cycle development delivers production-ready networks and dApps, not just proof-of-concepts.

Layer 1 & Layer 2 Development: Custom chains using Substrate, Cosmos SDK, or EVM rollups (Arbitrum, Optimism).
Smart Contract Suites: Secure, gas-optimized contracts for DeFi, NFTs, and governance, built with Solidity 0.8+ and Rust.
Node Infrastructure: Managed validator sets, RPC endpoints, and indexers with 99.9% uptime SLAs.

We focus on interoperability and future-proofing, ensuring your chain integrates seamlessly with existing ecosystems like Ethereum, Polkadot, and Cosmos.

Our process guarantees audit-ready code and a clear path from a 6-week MVP to a fully decentralized mainnet launch, managed by your team.

IMPLEMENTATION EXCELLENCE

Core Technical Capabilities We Deliver

We architect and deploy production-ready account abstraction solutions that deliver measurable improvements in user experience, security, and operational efficiency. Our focus is on delivering tangible business outcomes, not just technical features.

Custom Smart Account Development

We build secure, gas-optimized smart accounts (ERC-4337) tailored to your application logic. This includes session keys, batch transactions, and custom validation rules to enable seamless user onboarding and complex transaction flows.

ERC-4337

Standard

OpenZeppelin

Security Base

Paymaster & Gas Abstraction

Implement robust paymaster infrastructure to sponsor user transaction fees. We design systems for gasless onboarding, subscription models, and dApp-specific sponsorship to eliminate the #1 UX barrier in Web3.

PREDICTABLE, TRANSPARENT, AND SECURE

Our Delivery Process: From Specification to Mainnet

A structured, four-phase engagement model designed to deliver production-ready Account Abstraction infrastructure with zero surprises. We provide clear milestones, regular demos, and full audit transparency from day one.

Phase 1: Discovery & Architecture

We conduct a technical deep-dive to define your specific AA use case, select the optimal protocol (ERC-4337, Safe{Core}, etc.), and architect a modular, gas-efficient solution. Deliverables include a detailed technical specification and project roadmap.

1-2 weeks

Duration

100%

Specification Clarity

Phase 2: Smart Contract Development

Our senior Solidity engineers build your custom Paymasters, Account Factories, and Bundler integrations using audited patterns (OpenZeppelin). Development includes comprehensive unit and integration testing in a forked mainnet environment.

2-4 weeks

Typical Build Time

100%

Test Coverage Target

Phase 3: Security Audit & Testnet Deployment

All smart contracts undergo a rigorous internal security review followed by a formal audit with a partner firm (e.g., Spearbit). We deploy the full AA stack to a public testnet (Sepolia, Holesky) for user acceptance testing.

2-3 weeks

Audit Cycle

0 Critical

Issues to Mainnet

Phase 4: Mainnet Launch & Monitoring

We manage the secure mainnet deployment, configure high-availability Bundler and Paymaster infrastructure, and implement 24/7 monitoring with PagerDuty alerts. Includes handover documentation and 30 days of post-launch support.

Account Abstraction Implementation: Key Questions

Answers to the most common technical and commercial questions we receive from FinTechs and Web3 startups evaluating account abstraction services.

Standard deployments take 2-4 weeks from kickoff to mainnet launch. This includes smart account factory deployment, paymaster integration, and custom logic (e.g., multi-sig, session keys). Complex protocols with novel signer logic or cross-chain features may extend to 6-8 weeks. We provide a detailed sprint plan during discovery.
