Cyberk

I’m the co-founder of Fluxion Quest, a contribution platform that replaces click-farm quests with verifiable, skill-based participation. We let users earn real value by training AI agents, validating DePIN networks, or stress-testing advanced Web3 infrastructure.

We hired Cyberk to design and build the core Fluxion Quest platform. They needed to create the full contribution engine, verification logic, and UX needed to support skill-based, verifiable tasks across AI agents, DePIN networks, and advanced Web3 protocols.

Cyberk handled the end-to-end build of Fluxion Quest, covering both the platform logic and the user-facing experience. The main deliverables included:

We worked with 2–5 teammates from Cyberk.

We found them through a referral and the Clutch site. We chose them because they offered good value for the cost.

We worked together from January–February 2025.

Cyberk delivered clear, measurable results that showed real progress. We launched the MVP in 27 days, covering the contribution engine, verification layer, APIs, and frontend. We also processed 3,200+ verified contributions during pilot campaigns. The verification accuracy was >99% across AI, DePIN, and protocol-testing tasks. We onboarded 12 partner campaigns in the first month. User retention was +45% compared to traditional quest-style flows. We measured retention by tracking returning users across contribution cycles, not just single-session activity. Specifically, we compared traditional quest-style pilots (follow/retweet, one-off tasks) vs. Fluxion Quest pilots built by Cyberk using verifiable, skill-based contributions. The metric we used was the 7-day and 14-day return rate. A user was counted as “retained” if they returned to complete at least one additional contribution after their first verified task. Moreover, every submitted contribution (AI training input, DePIN validation, protocol interaction) generated a pass/fail result with detailed reason codes. We tracked mismatches between expected proofs (on-chain events, data hashes, activity signatures) and actual submissions. Fewer than 1% of submissions triggered verification errors or false positives. For quality control, we manually reviewed a random sample (~8–10%) of verified contributions across different task types. These audits checked whether the system-approved submissions genuinely met the task criteria. The manual review confirmed alignment with automated results in virtually all cases.

Cyberk’s project management was very structured and execution-focused, with clear milestones, fast feedback loops, and transparent progress tracking. They delivered on time — the Fluxion Quest MVP was completed within the planned timeline and launched as scheduled. We communicated through virtualk meetings, email, and messaging apps.

Their time management was outstanding. Cyberk planned work efficiently, prioritized the right tasks, and consistently delivered without delays.

No, everything was perfect.

I’m a project manager at Cypherus Capital, an IT company. We’re a decentralized “Know Your Agent” protocol that assigns on-chain credit scores to AI agents, enabling secure under-collateralized lending and reputation-based finance in the agent economy.

We hired Cyberk to design and build our core infrastructure, including the CypherID identity standard, on-chain credit scoring contracts, ZK-based reputation verification, and the backend APIs and dashboards needed to make Cypherus a functional credit layer for AI agents.

Cyberk handled the full technical and product scope for Cypherus, from protocol architecture to the operational platform. The main deliverables included:Additionally, Cyberk developed the backend APIs and dashboards in-house.

We found them through an online search, a referral, and the Clutch site. We chose them over other options because they had high ratings, good value for cost, and were referred to me.

We spent around $100,000.

We worked together from April–May 2024.

We delivered the MVP in under 30 days, covering CypherID, the scoring engine, APIs, and dashboards. We also onboarded 1,500+ simulated AI agents and issued CypherID identities in test environments. Moreover, we achieved 99.7% accuracy in credit score updates across staged trading and liquidation scenarios. Finally, we had less than 2-second latency for credit score queries via the API, meeting DeFi integration requirements.We tracked several clear KPIs to measure real adoption and performance after launch. For example, active agents with CypherID (weekly/monthly growth) grew from 120 to 680+ agents in the first four weeks (~5.6x growth).Moreover, credit score queries increased from ~3,500 to 21,000+ API calls/week, driven by DeFi protocol testing. Integration partners also expanded from three to nine protocols in sandbox or pilot mode. Finally, average API latency stabilized at ~1.3 seconds, well below the 2-second target.

Cyberk’s project management was highly structured and efficient. They worked with clear milestones, weekly sprints, and transparent reporting, which made it easy for us to track progress and adjust priorities. Moreover, they delivered on time — the Cypherus MVP was completed within the planned timeline, with all core modules.Our primary form of communication was virtual meetings and emails or messaging apps.

What impressed us most was Cyberk’s ability to handle extremely complex Web3 and AI-agent concepts and turn them into a working product very quickly. They combined deep protocol knowledge with strong execution speed.

No, overall, we were very satisfied with Cyberk’s delivery and collaboration. The project met our expectations in terms of speed, quality, and technical depth.

I'm a product owner at Terra Block, a Singapore-based digital banking platform for DAOs and Web3 companies. We unify multisig treasury management, automated crypto-to-fiat payroll and tax payments, and instant access to yield-bearing tokenized U.S. Treasuries into a single compliant neobank interface.

We needed to build our platform end-to-end as a compliant digital banking platform for DAOs. We wanted to launch quickly in Singapore with a production-ready product.

Cyberk has developed our platform, including the multisig treasury layer, automated crypto-to-fiat payroll and tax workflows, tokenized U.S. Treasury yield integration, and the full frontend dashboard. The team has delivered the core product stack for TerraBlock, not just isolated components. Specifically, they've completed:

We've worked with 2–5 teammates from Cyberk.

We found them through an online search and a referral. We chose them over other options because they offered good value for the cost.

We've spent around $50,000.

We worked together from February–March 2024.

Cyberk has delivered an MVP in 28 days, covering the full dashboard, treasury automation, Auto-Tax Off-ramp, and RWA yield modules. We've seen efficiency gains, reducing manual treasury and tax-prep workload by ~65% compared to spreadsheet-based workflows. We measured this by tracking the time our ops and finance team spent on core treasury tasks before and after using TerraBlock.

Cyberk's project management is highly organized and transparent, with clear sprint plans, frequent progress updates, and quick turnaround on feedback. The team has delivered on time — the full TerraBlock MVP was completed within the original four-week timeline. We communicate via virtual meetings and email or messaging apps.

I was impressed by Cyberk's dedication; they consistently went above and beyond, even working overtime when needed to ensure the project stays on track.

Sometimes their pace is so fast that we have to adjust our internal process to keep up.

I'm the co-founder of Stone Reserve Group, an IT company. We build a DePIN protocol that verifies and tokenizes real-world renewable energy usage into on-chain carbon credits for Bitcoin miners and AI data centers.

We needed help turning Stone Reserve from a concept into a real, buildable DePIN protocol.

Cyberk designed the Lithos Node architecture for tamper-proof energy data capture and built the blockchain layer for ZK-verified energy telemetry. The team handled the full end-to-end scope for Stone Reserve, covering hardware architecture, data verification, on-chain tokenization, and the carbon credit marketplace. Their main deliverables included Lithos Node architecture and firmware design, energy telemetry ingestion pipeline, and ZK-based verification framework.Moreover, Cyberk developed the blockchain smart contracts for governance, validator staking, and carbon credit minting. The team also built the user-facing marketplace foundation where verified carbon credits can be viewed, traded, and audited. Their work went beyond backend systems — they delivered the on-chain protocol layer, the data-verification pipeline, and the frontend components needed to make the marketplace usable by miners, data-center operators, and ESG partners.

We worked with 6-10 teammates from Cyberk.

We found Cyberk through an online search and a referral. We chose them over other options because they had a great culture fit, good value for cost, and were referred to me.

We spent $50,000 to $199,999.

We worked together from July–August 2024.

Our collaboration with Cyberk produced clear, measurable outcomes that validated Stone Reserve as a real on-chain carbon credit protocol. Cyberk delivered the MVP architecture in 28 days, covering Lithos Node firmware design, energy telemetry pipeline, ZK verification flow, smart contracts, and marketplace foundation.

Cyberk's project management was disciplined and highly reliable. They worked in clear sprints, communicated progress transparently, and flagged risks early instead of reacting late. We mainly communicated via virtual meetings, emails, and messaging apps.

What impressed us most was Cyberk's ability to handle an unusually complex stack: hardware abstraction, DePIN networking, ZK verification, tokenization, and a user-facing marketplace. The team still delivered everything quickly with production-level quality.

There was very little Cyberk could have done better.

I’m the head of growth at HappyHold Technologies, an information technology company. We’re a multi-chain crypto portfolio and trading app that helps users securely manage, earn, and grow their digital assets.

We hired Cyberk to design and build the full-stack product for HappyHold, from the core wallet and MPC security architecture to the multi-chain portfolio, trading, and yield features.

Cyberk designed and developed our mobile and web app UI/UX, a multi-chain wallet with MPC key management, portfolio tracking across 10+ chains, DEX aggregation for swaps, cross-chain bridge integrations, and advanced and quick trade modules. The team handled the end-to-end scope of the project, covering both frontend and backend development.

We worked with 2–5 teammates from Cyberk.

I found them through a referral and the Clutch site. I chose them over other options because they had high ratings, were referred to me, and their company values aligned with ours.

We worked together from August–October 2023.

Cyberk delivered a fully functional MVP in under four weeks, including wallet, trading, and analytics features. Within the first 30 days of internal testing, the app successfully indexed 10+ blockchains, processed 50,000+ test transactions with a >99.9% success rate, and achieved up to 30% gas savings through their routing and fee optimization logic.We tracked a clear set of KPIs focused on adoption, performance, and reliability after launch. On the user side, we monitored wallet connections, daily active users (DAU), and feature adoption, especially swaps, cross-chain transfers, and yield strategies. Within the first few weeks, over 65% of active users engaged with at least one trading or earning feature.On the system side, we tracked transaction success rate, gas savings, and execution latency. The app consistently maintained a >99.9% transaction success rate, average swap execution times under two seconds, and 20–30% lower gas costs compared to baseline DEX routing.

Cyberk’s project management was highly structured and efficient. They delivered all major milestones on time or ahead of schedule. We communicated via virtual meetings, emails, and messaging apps.

We were most impressed by how trustworthy and autonomous Cyberk was. After just a few alignment calls, they fully owned the execution, made the right technical decisions, and delivered without constant oversight.

No, there weren’t any.
