DeFi Platform Resilience: Ensuring Uptime During Peak Volatility
Client Overview
A rapidly growing decentralized finance (DeFi) lending platform with over $500M in Total Value Locked (TVL). Their existing infrastructure struggled to handle transaction spikes during high market volatility, leading to frequent downtime and lost opportunities for users.
The Problem
The platform's node infrastructure was not optimized for high-throughput, causing cascading failures during peak loads. This eroded user trust and put millions of dollars in liquidations at risk.
"Errna's team didn't just fix our downtime issues; they re-architected our node infrastructure for resilience. During the last market crash, we were one of the few platforms that remained fully operational. That's not just support; that's a competitive advantage."
- Alex Royce, CTO, FinSecure CapitalKey Challenges
- Frequent node synchronization issues.
- Inadequate load balancing for RPC requests.
- Lack of a 24/7 monitoring and response team.
- High latency in transaction processing.
Our Solution
We implemented a geo-distributed, load-balanced RPC node cluster and established a 24/7 proactive monitoring protocol.
- Deployed a high-availability node architecture across multiple cloud providers.
- Implemented an intelligent caching layer to reduce database load.
- Established real-time alerting integrated with our 24/7 incident response team.
- Optimized database queries and network parameters for faster block propagation.
Supply Chain Data Integrity: Fortifying a Hyperledger Network
Client Overview
A global logistics consortium using a Hyperledger Fabric network to track high-value shipments. They faced challenges with data discrepancies between participating organizations, leading to costly disputes and delays.
The Problem
Inconsistent chaincode versions and misconfigured peer nodes across the consortium were causing data forks and validation errors, undermining the very purpose of the blockchain: to be a single source of truth.
"The data integrity issues were becoming a deal-breaker for our consortium members. Errna's support team standardized our network configuration and implemented automated checks that restored everyone's faith in the platform. Their expertise in Hyperledger Fabric is unparalleled."
- Maria Garcia, Head of Digital Transformation, Global Logistics Inc.Key Challenges
- Lack of a standardized deployment process for new members.
- Manual and error-prone chaincode update procedures.
- No central monitoring of peer node health and connectivity.
- Difficulty in tracing the source of data discrepancies.
Our Solution
We developed a comprehensive governance and maintenance framework for the consortium's Hyperledger Fabric network.
- Created automated scripts for standardized peer node deployment and configuration.
- Implemented a version-controlled, multi-stage chaincode deployment pipeline.
- Deployed a centralized monitoring dashboard for real-time visibility into the health of all nodes.
- Established a regular data reconciliation process to proactively identify and resolve inconsistencies.
NFT Marketplace Security: Preventing a Multi-Million Dollar Exploit
Client Overview
A popular NFT marketplace built on Ethereum, experiencing rapid growth. While their platform was functional, their smart contracts had been developed quickly and had not undergone a rigorous, ongoing security review.
The Problem
The client was unaware of a critical reentrancy vulnerability in their auction contract that could have allowed an attacker to drain millions of dollars worth of WETH from the platform's escrow.
"Errna's proactive security audit was the best investment we've ever made. They found a critical flaw that our original auditors missed. Their maintenance service isn't just about keeping the lights on; it's about protecting our entire business and our users' assets. We sleep better at night knowing they're watching over our code."
- Ben Carter, Founder, ArtBlock NFTKey Challenges
- Smart contracts deployed without a full security lifecycle.
- No monitoring for unusual on-chain activity.
- Lack of an incident response plan for smart contract exploits.
- Pressure to deploy new features quickly, often at the expense of security reviews.
Our Solution
We instituted a continuous security maintenance program, starting with a deep-dive audit of all existing smart contracts.
- Identified and helped remediate the critical reentrancy vulnerability.
- Implemented the Checks-Effects-Interactions pattern in all new smart contracts.
- Deployed an on-chain monitoring service to alert on suspicious transaction patterns.
- Developed and drilled an emergency incident response plan, including contract pausing mechanisms.

Frequently Asked Questions
Blockchain maintenance is the ongoing process of monitoring, securing, and updating a blockchain network to ensure it runs efficiently and without interruption. It's critical because unlike traditional software, blockchain downtime or security breaches can result in irreversible financial loss and a permanent loss of user trust. Proactive maintenance prevents these catastrophic failures.
We support a wide range of public and private blockchains. Our expertise includes EVM-compatible chains like Ethereum, Polygon, and BSC; high-performance chains like Solana; and enterprise-grade private networks like Hyperledger Fabric and R3 Corda. We tailor our support to your specific technology stack.
Security is our top priority. We employ a multi-layered approach that includes 24/7 monitoring for suspicious activity, regular security audits of nodes and smart contracts, immediate patching of vulnerabilities, and adherence to strict access control protocols. Our services are backed by our SOC 2 and ISO 27001 certifications.
Absolutely. Managing hard forks is one of our core competencies. We handle the entire process: analyzing the upgrade, testing it in a staging environment, coordinating with your node operators, and executing the upgrade across your network to ensure a smooth, seamless transition with zero downtime.
We offer flexible, subscription-based pricing models tailored to your needs. Our packages are based on factors like the size and complexity of your network, the number of nodes, and the required service level agreement (SLA). Our models provide predictable monthly costs that are typically more affordable than building a comparable in-house 24/7 team.
Our SLAs define specific response times based on issue severity. For critical, network-threatening incidents, we guarantee a response time of under 15 minutes, 24/7/365. Our goal is to begin active resolution immediately to minimize any potential impact on your business.
