Blockchain platforms our teams have production experience with.

We embed with your product, security, and infrastructure teams to deliver blockchain solutions that are secure, scalable, and maintainable. Whether you need to build DeFi protocols or enterprise blockchain platforms, our squads adapt to your security requirements and deployment processes.

• Production-grade smart contracts written in Solidity, Rust, or Vyper with comprehensive security audits before mainnet deployment.
• Full-stack DApp development using Web3.js, Ethers.js, and modern frontend frameworks to create seamless user experiences.
• Enterprise blockchain solutions built on Hyperledger Fabric, Quorum, or custom architectures for supply chain, identity, and financial services.
• Token development and deployment including ERC-20, ERC-721, ERC-1155, and custom token standards with proper governance mechanisms.
• Security-first development with automated vulnerability scanning, formal verification, and comprehensive test coverage including edge cases.
• Collaborative delivery leadership that syncs with your outsourced development initiatives and ensures blockchain best practices are followed.

We partner with CTOs, engineering managers, and product leaders who need a blockchain squad that can deliver secure, audited solutions. Every engagement comes with a delivery lead, blockchain architect, and a security review process integrated with your workflows.

• Security-first staffing with engineers who have deployed production smart contracts and DApps in DeFi, NFTs, and enterprise blockchain.
• Architecture for immutability leveraging gas optimization, upgrade patterns, and consensus mechanism design to ensure long-term viability.
• Multi-platform expertise that keeps your options open—we work with Ethereum, Hyperledger, Solana, and custom chains.

Our team in the Americas overlaps with U.S. time zones and collaborates in English and Spanish. We maintain transparent development processes with security audit checkpoints so you always know the status of your blockchain deployment.

• Security rituals that matter — code reviews, automated scanning, formal verification, and third-party audits before mainnet.
• Gas optimization focus with proactive profiling, transaction cost analysis, and continuous monitoring of on-chain operations.
• Clear security metrics tied to audit results, vulnerability counts, and mainnet deployment readiness you can track.

1. Blockchain architecture review

We review your use case, consensus requirements, and security needs. Expect platform recommendations, smart contract design reviews, and a security-first roadmap within the first week.

2. Security-aligned squad

We define team composition with smart contract developers, security auditors, and blockchain architects. Tooling includes Hardhat, Truffle, security scanners, and your existing development infrastructure.

3. Audited delivery

We ship in testnet increments, conduct security audits, and share gas optimization, security, and deployment readiness metrics so you can confidently deploy to mainnet.

SupplyChainTrace, a logistics technology company, needed to build a blockchain-based traceability platform without compromising their existing supply chain management systems. Their team was juggling compliance requirements, partner integrations, and pressure to deliver transparent product tracking.

We partnered with their CTO to assemble a mixed squad of blockchain architects, smart contract developers, and security auditors who worked alongside internal leads. Together we:

• Designed a Hyperledger Fabric consortium blockchain that integrated with existing ERP systems via APIs.
• Developed smart contracts for product provenance tracking that reduced fraud incidents by 45%.
• Conducted comprehensive security audits and implemented upgrade mechanisms for future protocol changes.

Every team blends experienced blockchain developers with the roles you need to deliver secure, production-ready solutions. We frequently combine:

• Smart contract developers focused on Solidity, Rust, or Vyper with experience in DeFi, NFTs, or enterprise blockchain.
• Blockchain architects who design consensus mechanisms, tokenomics, and scalable blockchain architectures.
• Web3 frontend developers building DApp interfaces with React, Vue, or Angular and wallet integration.
• Security auditors conducting smart contract reviews, vulnerability assessments, and formal verification.
• DevOps engineers managing blockchain node infrastructure, testnets, and mainnet deployment pipelines.
• Delivery leads ensuring security checkpoints, audit coordination, and cross-team communication.

Choose the engagement model that matches your blockchain roadmap:

• Dedicated blockchain pods that behave like an extension of your in-house group—ideal when you want to maintain full control over smart contract logic and security.
• Co-delivery teams where we partner with your staff augmentation strategy to reinforce existing blockchain squads.
• Managed blockchain outcomes with SLAs, security audit schedules, and deployment readiness metrics owned by Siblings Software.

Need to cover other technologies alongside blockchain? We can combine with our blockchain development services and cross-functional expertise across APIs, cloud infrastructure, and data analytics.
