Industries

FinTech & DeFi

Problem: skyrocketing gas fees and slow settlement.
Solution: Outstaffed Rollup developers design zk-Rollup payment rails, build Solidity circuits, and integrate Layer-2 gateways into core banking APIs. They audit smart contracts, implement proof aggregation, and keep compliance intact. Result: instant, low-fee transfers that attract new users and sustain profitability.

Supply-Chain & IoT

Traceability demands tamper-proof, low-cost logging. Rollup engineers connect RFID gateways to Optimistic Rollup chains, batching thousands of sensor events with negligible gas while preserving data integrity. Outstaffing cuts lead time so manufacturers gain real-time visibility without huge CapEx.

Healthcare Records

PHI security + scalability is tricky. Augmented Rollup teams create privacy-preserving proofs, encrypt off-chain data, and ensure HIPAA conformity. Hospitals enjoy immutable audit trails and sub-second retrieval without sharing sensitive info publicly.

Gaming & NFT

Players expect zero-lag asset trades. Hire Rollup developer specialists implement high-TPS sidechains, craft minting smart-contracts, and integrate wallets into Unity/Unreal. Outstaffing keeps budgets sane while launch dates stay aggressive.

AdTech Analytics

Billions of bid events overwhelm L1. Rollup devs stream data to layer-2, compressing logs 100:1, enabling real-time dashboards. Pay only for active talent as traffic spikes.

RegTech & Compliance

Financial institutions must prove data lineage. Rollup experts craft zero-knowledge proof pipelines, automate audits, and slash reporting cycles. Outstaffing ensures fast access to niche cryptography skills.

Energy & Utilities

Smart-meter data floods networks. Layer-2 Rollup solutions batch readings securely, reducing infra cost. Outstaffed engineers integrate SCADA with on-chain analytics, boosting grid insights.

eCommerce

Carts abandon when fees bite. Rollup programmers build checkout plugins that shift payment finality to L2, trimming fees and enhancing UX, while merchants avoid hiring delays.

GovTech

Public-sector tenders need transparency. Rollup devs create zk-voting, tender tracking, and citizen ID proofs. Using augmentation, agencies access rare blockchain talent within procurement limits.

What is the real cost to hire Rollup developers through smartbrain.io compared to in-house?

When you Hire Rollup developer talent in-house, total cost of ownership includes salary, benefits, recruiter fees, equity, hardware, office space, and ongoing training—often 1.7× the base salary. With smartbrain.io you pay a transparent hourly rate that bundles payroll tax, health insurance, and management overhead. Because developers stay on our books, you avoid legal entities in multiple states or countries. Clients typically report savings of 35-55 % over a two-year horizon while gaining the flexibility to scale headcount up or down in days.

How does smartbrain.io protect intellectual property when we outstaff Rollup engineers?

Every engineer signs a strict NDA and an IP assignment agreement that mirrors your internal policies.
