You’ve probably used products built by our cryptocurrency developers.
Our teams have delivered production-grade blockchain platforms, consumer wallets, and regulated exchange backends for clients in FinTech, decentralized finance, and blockchain intelligence.
We design and build permissioned and public blockchain platforms for a wide range of use cases, from payment rails to enterprise data-sharing networks. Our solutions are engineered for high transaction throughput, strict uptime targets, and fine-grained role management. To deliver that reliability, our architects work closely with client security, DevOps, and product teams—aligning consensus models, node orchestration, and data strategies with existing infrastructure.
We create custodial and self-custodial wallets that balance usability with security, designed to protect keys, manage multi-asset portfolios, and interface with diverse chains. Our teams embed secure enclaves, biometric authentication, and transaction-level risk monitoring, then integrate with backend KYC, AML, and analytics services. Users gain frictionless access while organizations maintain control and observability.
Building a high-performance exchange means solving for ultra-low latency, massive market-data bursts, and intense regulatory scrutiny. We build the core components to meet these demands: matching engines, settlement layers, and risk controls. By integrating FIX/REST/WebSocket gateways and hardware-assisted HSM custody, we achieve sub-millisecond performance without sacrificing compliance, ensuring your exchange operates with reliability and scales predictably under peak load.
One of the key risks with blockchain technology is that mistakes are irreversible and public, making secure coding and formal verification critical. We write and validate smart contracts governing assets, governance, and business logic. Our engineers apply structured review processes, static analysis, and cross-team threat modeling to eliminate vulnerabilities before deployment.
Complex jurisdictional rules, investor accreditation, and on-chain/off-chain reconciliation require deliberate design. We architect crypto token standards, distribution mechanics, and compliance workflows for security tokens, utility tokens, and asset-backed NFTs. Our engineers coordinate with legal counsel, implement cap-table smart contracts, and automate reporting to align digital assets with existing capital-markets processes.
DeFi platforms promise transparency and composability, but they operate in a high-risk environment of volatile liquidity and oracle dependencies. Our development process is built around managing that risk. We combine rigorous protocol design with automated testing on forked testnets to catch vulnerabilities before deployment. For live applications, we implement circuit-breaker safeguards to protect capital, giving you a secure and reliable entry into decentralized finance.
Getting real-time settlement data and token balances from the blockchain into legacy ERP and analytics stacks is a common integration challenge. We solve this by exposing blockchain functionality through resilient API gateways and event streams. Our middleware maps on-chain events to familiar REST/GraphQL schemas, adds authentication and rate-limiting, and ensures observability across hybrid environments.
We perform holistic security assessments for new or existing blockchain platforms. Our specialists conduct smart contract audits, review your custody models, smart contracts, and key management processes against established frameworks like the CryptoCurrency Security Standard (CCSS) and regulatory guidelines from SOC 2 and FATF. We deliver an actionable remediation roadmap to fix vulnerabilities, satisfy auditors, and accelerate regulator approvals.

By implementing CI/CD pipelines and refactoring the user onboarding experience, we enabled secure, rapid custom app development. This two-year engagement helped Azlo double its customer count and maintain a competitive edge.
The ecosystem we use for cryptocurrency development:
We rely on a toolchain built around long-term maintainability, auditability, and regulatory alignment. Every selection supports predictable delivery and clean hand-off to internal teams.
Blockchain Protocols and SDKs
We build on the most popular blockchain platforms, choosing protocols with strong governance and proven mainnet performance to minimize risk. Our architects benchmark throughput, fee volatility, and tooling maturity before recommending a stack.
Smart Contract Frameworks
Immutable code demands secure-by-design tooling and repeatable test workflows. Continuous integration pipelines enforce static analysis and differential testing for every pull request.
Wallet and Key Management
Key custody defines risk posture. We integrate hardware isolation and policy-based approvals from day one. Combined with multi-party approval workflows, this approach preserves usability while hardening custody against insider threats.
Infrastructure and DevOps
Hardened automation keeps nodes, bridges, and CI pipelines reproducible and compliant with change-management controls. Automated rollbacks and canary deployments let teams upgrade nodes and contracts without service interruption.
Security Auditing and Monitoring
We combine automated analysis with manual review to surface vulnerabilities early and maintain continuous runtime assurance. Dedicated dashboards surface on-chain anomalies and alert security teams in near real time.
Compliance and Chain Intelligence
Real-time AML screening and travel-rule data exchange reduce regulatory friction and accelerate approvals. The same data feeds power transaction screening, liquidity risk scoring, and audit-ready reporting.
Data Indexing & Querying
Reading raw data from the blockchain is slow and inefficient. We use indexing protocols to organize on-chain data into high-performance APIs, allowing applications to feel as fast and responsive as their Web2 counterparts without sacrificing decentralization.
Oracles and Off-Chain Data
Smart contracts require reliable, tamper-proof access to real-world data like asset prices and event outcomes. We integrate industry-leading oracle networks that provide decentralized data feeds, securing DeFi protocols and other data-dependent applications against manipulation.
Decentralized Storage
To achieve true decentralization and censorship resistance, dApp front-ends and metadata must live on decentralized networks, not centralized servers. We use decentralized storage protocols to ensure data permanence and eliminate single points of failure.
Front-End & dApp Libraries
A secure backend is useless without a safe and intuitive user interface. We use modern, battle-tested libraries to handle wallet connections, transaction signing, and smart contract interactions, ensuring a seamless and secure user experience.

What engagement models do you offer, and can we start small?
We offer flexible models: staff augmentation, dedicated teams, or end-to-end outsourcing. Yes, you can start small, with one or two developers, then scale up as business needs change.
How quickly can you scale the team if scope expands?
We maintain a bench of 4000+ pre-vetted senior engineers, allowing us to add specialists to your blockchain project in as little as 2 weeks. Our model lets you scale up to meet tight deadlines or shifting priorities without losing momentum.
How do you optimize gas fees and throughput for high-volume workloads?
Our teams use established techniques like transaction batching, calldata compression, and Layer-2 rollups, then validate the results with rigorous stress-testing to ensure efficiency at scale.
What are the most common smart contract failure modes you mitigate?
Because blockchain code is immutable, the most common failures are irreversible. We focus on preventing the top three: unchecked math (reentrancy, overflows), unguarded external calls, and flawed upgrade logic. Our mandatory process of formal verification, static analysis, and multi-sig deployment is designed to catch these critical bugs before they ever reach mainnet.
How do you handle major protocol upgrades and hard forks?
We treat protocol upgrades as a predictable part of the development lifecycle. Our process involves actively monitoring core developer channels, running full regression tests on public testnets, and performing impact analyses weeks before a network event. This proactive approach ensures your application has a smooth transition during hard forks.
How do you handle evidence collection for compliance standards like SOC 2?
Our CI/CD pipelines are designed to make audits painless. Every build automatically generates immutable logs and security scan reports, which are exported to a central repository. This gives your compliance team real-time access to the evidence they need without distracting developers.
Can you migrate legacy token contracts to newer standards?
Yes. We audit bytecode, map state, and deploy proxy patterns to preserve balances while adopting modern ERC or SPL standards.
What is your process for securing private keys in production?
Keys are stored in HSM-backed vaults with MPC signing and dual control, eliminating single-person compromise risk.
