Secure, production-ready smart contracts built for scale and compliance.
We architect and deploy custom smart contracts on EVM-compatible chains (Ethereum, Polygon, Arbitrum) and Solana. Our development process is built for enterprise-grade security and speed.
We don't just write code; we deliver secure, auditable financial primitives that power your core business logic.
Our team specializes in:
ERC-20, ERC-721, ERC-1155, and SPL token implementations with advanced features (vesting, minting, governance).We deliver production-ready, audited Substrate pallets that handle the full wallet lifecycle—from secure key management to seamless transaction orchestration. Each module is built for integration, not just demonstration.
A native Substrate wallet module isn't just a feature—it's a foundational component for sovereignty, performance, and user experience. Here's how it delivers long-term value for your blockchain project.
A technical comparison of the two primary approaches for building custom wallets on Substrate, highlighting key trade-offs in performance, flexibility, and security for your blockchain project.
| Architectural Factor | Native Runtime Pallets | Smart Contract Wallets |
|---|---|---|
Development Complexity | High (Rust, Substrate SDK) | Medium (ink!, Solidity) |
Runtime Performance | Native speed, < 100ms | VM overhead, 200-500ms |
Upgrade Flexibility | Requires runtime upgrade | Contract can be upgraded |
Gas Cost for Users | Minimal (weight-based) | Higher (gas metering) |
Security Surface | Smaller (runtime logic) | Larger (contract + VM) |
Time to MVP | 8-12 weeks | 4-6 weeks |
Chain Coupling | Tightly coupled | Loosely coupled |
Audit & Testing Scope | Full runtime audit | Primarily contract audit |
Typical Use Case | Core chain treasury, high-TX | User-facing dApp wallets |
Chainscore Recommendation | For performance-critical, native features | For rapid iteration & EVM compatibility |
A structured, security-first approach to deliver production-ready Substrate wallet modules that integrate seamlessly into your application, ensuring reliability and rapid time-to-market.
We begin with a deep technical assessment of your existing stack and requirements to design a modular wallet architecture. This ensures optimal key management, transaction flow, and future scalability on Substrate-based chains.
Secure implementation of core wallet functionalities: key generation/derivation, transaction signing, multi-signature support, and balance tracking. Built with Rust, sp_core, and subxt following Parity's best practices.
Every module undergoes rigorous internal security review and automated testing. We integrate with tools like cargo-audit and cargo-tarpaulin for vulnerability scanning and coverage, preparing artifacts for external audits.
We deliver a clean, well-documented SDK (Rust/JS) with examples for easy integration into your frontend or backend. Includes comprehensive documentation for APIs, error handling, and event listeners.
We deploy the module to a staging environment (e.g., a testnet or local node) and execute end-to-end integration tests. We validate performance under load and ensure compatibility with target chains like Polkadot or Kusama.
Post-launch, we provide monitoring guidance, security patch updates for dependency vulnerabilities, and support for chain runtime upgrades. Optional SLA-based support plans are available.
A transparent breakdown of our phased approach to delivering a secure, production-ready Substrate wallet module, from initial architecture to ongoing support.

Answers to the most common questions CTOs and technical founders ask when evaluating a custom Substrate wallet module development partner.
A standard Substrate wallet module with core features (key management, transaction signing, balance display) can be delivered in 2-4 weeks. Complex integrations (multi-chain support, advanced governance, custom cryptography) extend the timeline to 6-10 weeks. We follow a phased delivery model, providing a working prototype for review within the first 7-10 days.
