overview
CORE SERVICE

Smart Contract Development

Secure, audited smart contracts built to your exact specifications.

We architect and deploy production-ready smart contracts that power your application's core logic. Our development process ensures security-first design, gas optimization, and full audit readiness from day one.

  • Custom Logic: Build on ERC-20, ERC-721, ERC-1155 or bespoke standards.
  • Security Framework: Integrated OpenZeppelin libraries and formal verification patterns.
  • Deployment & Management: Full lifecycle support from testnet to mainnet with upgradeability planning.

Reduce your time-to-market with battle-tested contracts and avoid costly vulnerabilities that can derail a launch.

STRATEGIC ADVANTAGES

Why Embed a Bitcoin Wallet in Your IoT Device

Transform your hardware from a simple data collector into a sovereign financial node. Our firmware unlocks new revenue streams, enhances security, and creates a direct, trustless connection to the Bitcoin economy.

01

New Revenue Streams

Enable micropayments, pay-per-use models, and automated machine-to-machine (M2M) transactions. Your device can autonomously earn, pay for services, or sell data directly on-chain, creating a direct monetization layer.

Technical and Commercial Questions

IoT Bitcoin Firmware Development FAQs

Answers to common questions from CTOs and product leads evaluating embedded Bitcoin wallet solutions for their hardware.

For a standard IoT Bitcoin wallet firmware project, we deliver a production-ready build in 4-6 weeks. This includes a 2-week discovery/architecture phase, 2-3 weeks of core development with weekly demos, and a final week for security hardening and deployment. Complex integrations (e.g., multi-signature, custom HSM) can extend this to 8-10 weeks. We provide a detailed sprint-by-sprint Gantt chart at project kickoff.
