You’ve probably used products built by our blockchain developers.
From blockchain intelligence to trading platforms, our teams have shipped custom blockchain solutions for clients worldwide. We start quickly, scale with demand, and integrate with the systems you already run.
We design and ship blockchain platforms on Ethereum, Hyperledger, or Corda. Our smart contracts are readable, versioned, and tested with fuzzing and property checks. We define interface schemas, set version windows, and wire deterministic builds into CI so promotion requires passing gates. Gas and throughput are profiled with load harnesses. Our releases include runbooks, rollback plans, and evidence that your auditor can review. The outcome is a production platform that integrates cleanly with your architecture and delivery cadence.
Privacy, governance, and data residency drive our blockchain development. We set membership services, RBAC, endorsement policies, and private data collections that match legal and security requirements unique to blockchain technology. We model throughput and failure modes, then validate with integration tests that mirror real operations. You get a ledger that passes audit, survives incident drills, and supports controlled growth without disrupting upstream systems.
We build token platforms with clear lifecycle rules for issuance, transfers, redemptions, and corporate actions. Our experts encode business logic in smart contracts that power your token operations. We define on-chain and off-chain boundaries, reconcile state with back-office systems, and design settlement flows that meet finance controls. Cost and latency are tuned through batching and L2 strategies. Your operations team receives dashboards, reconciliation jobs, and playbooks that keep accounting and compliance aligned.
We integrate KYC providers, sanctions screening, and step-up verification, then capture evidence as part of CI and runtime. We implement permission controls, data retention rules, and consent management in code, then validate enforcement in staging environments. Audit trails span approvals, deployments, and access changes, producing artifacts suitable for SOC 2 and GDPR reviews. The result is a verifiable identity layer that supports scale without slowing product delivery.
Real value appears when your entire blockchain ecosystem connects to ERP, core banking, CRM, and analytics. We publish event schemas, version OpenAPI or GraphQL contracts, and build idempotent gateways with replay and backpressure. We validate integrations with parity tests and synthetic transactions, then hand over runbooks and migration plans. Your teams keep existing systems, while products gain reliable blockchain data and event signals.
Keys represent business risk. We design custody with HSM or cloud KMS, role approvals, break-glass procedures, and policy as code. We configure secret rotation, implement wallet interfaces with hardware-backed storage, and document recovery procedures for your operations team. Each control is monitored and logged for audit. You gain predictable custody, usable wallets, and the operational confidence to scale transactions safely.
We harden code before an external audit ever starts. We integrate static analysis, property tests, and differential fuzzing into CI and remediate all findings before release. For critical components, we define specifications and apply model checking or formal verification where it pays off. Threat models, SBOMs, and dependency reports are produced as artifacts. When auditors engage, we coordinate fixes, retests, and promotion gates. You ship with evidence, not promises, and reduce production risk.
Protocol upgrades introduce coordination risk across distributed networks. We plan and execute blockchain upgrades using dual-run or blue-green patterns, rehearse rollback procedures, and document change windows that align with your release calendar. Load testing validates capacity before cutover, and post-upgrade reviews capture lessons for future releases. Your network upgrades land predictably without service disruptions.

Vetted Blockchain Talent
Our blockchain developers average 10+ years of experience. We hire less than 1% of applicants after hands-on evaluations and interviews tailored to blockchain technologies. These tests go beyond theory, covering real scenarios like securing smart contracts and integrating decentralized systems into enterprise platforms. You can trust you’ll work directly with senior blockchain developers who’ve already proven they can deliver at the highest level.
Time Zone Alignment, Real-time Collaboration
Our senior engineers in LATAM work on your schedule, overlapping US business hours for standups, incidents, and go-lives. This real-time alignment means reviews happen faster, issues get resolved on the spot, and launches stay on track without overnight delays. And because our nearshore teams embed directly into your workflows, delivery remains consistent even as priorities shift or team composition changes.
Audit-ready Delivery
Our teams are fluent in SOC 2, ISO 27001, GDPR, AML/KYC, and PCI DSS, so compliance is ensured throughout the pipeline. We publish schemas, enforce contracts in CI, and capture approvals, test evidence, and change logs automatically. This keeps reviews short and sign-offs predictable.
Dozens of blockchain projects delivered.
Our clients rely on us for blockchain platforms that meet high technical and business standards.
Abra, the first worldwide peer-to-peer crypto transfer network, needed to simplify trading for 2 million users in 150 countries while broadening liquidity options. Over a four-year staff-augmentation engagement, our senior engineers boosted test automation coverage, tightened QA and risk-assessment flows, and delivered new ACH and wire modules to keep funds moving fast. We also built an ETFs-and-stocks trading engine that let users diversify beyond crypto assets.
A leading blockchain-intelligence provider to regulators and exchanges in 60+ countries sought to migrate its existing blockchain platform to a leaner architecture without compromising security or compliance. Our team of 6 engineers spent 3 years pruning idle servers, designing cold-storage wallet workflows, and piping raw data into the cloud. The move to a serverless stack cut compute costs by roughly 20% while ensuring all data handling met industry standards.
To support its rapidly growing user base of entrepreneurs, digital banking platform Azlo needed to accelerate feature delivery while meeting strict FinTech regulations. Our team of engineers developed new features like invoice automation and budget envelopes. 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 blockchain projects:
We standardize on mature, well-supported tools that favor stability, maintainability, and auditability over novelty. Choices are guided by security posture, documentation quality, vendor neutrality, and long-term operability inside regulated environments.
Core Protocols and Networks
We choose networks with active governance, predictable upgrade windows, and production references in regulated sectors. Selection criteria include support SLAs, documented change paths, and compatibility with privacy, RBAC, and data residency requirements.
Smart Contract Languages and Runtimes
Readability and auditability come first. We standardize on languages with static analysis support, typed interfaces, and deterministic builds, then pin versions and publish interface contracts so downstream teams can integrate safely.
Development Frameworks and Testing
Delivery speed without regressions requires opinionated scaffolds, local chains, and consistent fixtures. We codify reproducible environments, smoke tests, and fuzzing in CI to protect main branches.
Identity, Access, and Key Management
Keys represent business risk. We operate hardware-backed storage, short-lived credentials, and policy-based approvals with documented recovery paths that security teams can audit.
Security, Auditing, and Verification
We run static analysis, property-based tests, and differential fuzzing before external audits. Findings are tracked as work items with fixes gated by CI policies and peer review.
Data, Oracles, and Off-Chain Services
Professional systems blend on-chain guarantees with off-chain processing. We choose oracles and data layers with uptime records, transparent economics, and signed evidence for audits.
DevOps, IaC, and Release Automation
Deterministic builds, immutable artifacts, and versioned pipelines keep drift in check. We sign artifacts, capture provenance, and use staged promotions so cutovers are predictable and auditable.
Observability and Operations
We instrument blockchain infrastructure with monitoring tools that track node performance, aggregate logs from distributed systems, and provide alerting for network health and transaction issues.
We choose networks with active governance, predictable upgrade windows, and production references in regulated sectors. Selection criteria include support SLAs, documented change paths, and compatibility with privacy, RBAC, and data residency requirements.
