Modular Wallet & Account Abstraction

We build chain-agnostic smart accounts and wallet infrastructure that seamlessly operate across modular ecosystems, abstracting complexity for your users.
Chainscore © 2026
overview
FULL-STACK BUILD

Custom Blockchain Development

End-to-end blockchain solutions from protocol design to mainnet deployment.

We architect and build custom blockchains, sidechains, and application-specific rollups tailored to your business logic. Our full-cycle development delivers production-ready networks with optimized consensus, native tokenomics, and secure validator sets.

  • Layer 1 & 2 Development: Build sovereign chains or EVM/Cosmos-SDK rollups for scalability.
  • Protocol Design: Custom consensus (PoS, PoA), fee markets, and governance modules.
  • Node Infrastructure: Deploy and manage validator, RPC, and indexer nodes with 99.9% uptime SLA.
  • Mainnet Launch: Comprehensive support for genesis, token distribution, and go-live security audits.

From whitepaper to a live, secure network in 8-12 weeks. We handle the complexity so you can focus on your product.

PROVEN PROCESS

Our Development Methodology

A structured, security-first approach to building modular smart accounts that delivers production-ready code on time and within budget.

01

Architecture & Specification

We begin with a deep technical discovery to define your custom account logic, module ecosystem, and gas optimization strategy. This phase establishes a clear technical spec, ensuring alignment on deliverables and timelines.
