Technical Support for Blockchain Projects

Blockchain infrastructure fails differently than regular web services. A node might get stuck on a specific block due to an edge case in the consensus client. A smart contract behaves correctly under test but becomes unpredictable when interacting with another protocol via a flash loan. An RPC provider returns stale data without explicit errors. Supporting such systems requires specialized knowledge that an ordinary DevOps team doesn't have. We've provided blockchain support for over five years, servicing more than 50 projects with a cumulative TVL exceeding $50M. Our team ensures your infrastructure's stability 24/7 with guaranteed SLAs and certified engineers. We handle monitoring, incident response, updates, and consulting—so you can focus on product development. Our blockchain support covers blockchain monitoring, blockchain incident response, and blockchain infrastructure updates. Contact us to discuss your project details.

What Our Blockchain Support Includes

Infrastructure Monitoring

We track on-chain events of smart contracts (unusual calls, state changes), node status (sync lag, peer count, client version), validator or sequencer health, bridge contract functionality, and service account balances (relayer, deployer, keeper). For on-chain monitoring we use OpenZeppelin Defender: Sentinels track specific events and calls on the contract, such as pause() or upgradeTo(). On trigger, a webhook sends alerts to Telegram or PagerDuty.

Incident Response

We follow a duty schedule with SLA on first response, diagnose and fix node issues, perform emergency contract pause if an exploit is detected, and coordinate with auditors during security incidents.

Maintenance and Updates

We update clients (Geth, Lighthouse, etc.) on new releases, apply hotfixes to smart contracts via upgrade mechanism, rotate service account keys, and update RPC endpoints when providers degrade.

What's Included in Our Support Package

  • Documentation: Detailed runbooks for incident response, monitoring setup, and update procedures.
  • Access: Secure VPN/SSH access for monitoring, plus dashboards (Grafana, Prometheus) and alerting channels.
  • Training: Onboarding sessions for your team on how to interact with our support and use provided tools.
  • Support: 24/7 coverage via dedicated communication channels (Telegram, Slack, PagerDuty) with response times as per SLA.

Monitoring Tools We Use

Basic monitoring is built on Prometheus + Grafana + Alertmanager. Here is a typical configuration:

# docker-compose monitoring stack services: prometheus: image: prom/prometheus:latest volumes: - ./prometheus.yml:/etc/prometheus/prometheus.yml grafana: image: grafana/grafana:latest ports: ["3000:3000"] alertmanager: image: prom/alertmanager:latest volumes: - ./alertmanager.yml:/etc/alertmanager/alertmanager.yml 

Prometheus alert rules for a typical EVM project:

groups: - name: blockchain rules: - alert: NodeSyncLag expr: eth_syncing_current_block - eth_syncing_highest_block > 50 for: 5m labels: { severity: warning } annotations: summary: "Node is {{ $value }} blocks behind head" - alert: ServiceWalletLowBalance expr: eth_balance{account="relayer"} < 0.1 for: 1m labels: { severity: critical } annotations: summary: "Relayer wallet balance critical: {{ $value }} ETH" - alert: ContractPaused expr: contract_is_paused == 1 for: 0m labels: { severity: critical } annotations: summary: "Contract {{ $labels.contract }} is paused" 

For on-chain smart contract monitoring we use Sentinels. Example configuration via Defender API:

{ "type": "BLOCK", "network": "mainnet", "addresses": ["0xYOUR_CONTRACT"], "abi": [...], "eventConditions": [ { "eventSignature": "RoleGranted(bytes32,address,address)" }, { "eventSignature": "Upgraded(address)" } ], "functionConditions": [ { "functionSignature": "pause()" } ] } 

Our monitoring detects issues three times faster than relying solely on node uptime checks.

Security Incident Response Process

Every protocol with TVL should have a runbook. Typical scenario:

  1. Detection (automatic alert or external report).
  2. Assessment (5–15 minutes): damage scale, is exploit active, can we pause.
  3. Pause (if contract is pausable): immediately, don't wait for full analysis.
  4. Notification (15–30 minutes): team, token holders, auditors.
  5. Investigation: analyze transactions via Tenderly, trace exploit.
  6. Fix: hotfix contract, audit fix.
  7. Post-mortem: public report.

For the pause step, the pauser role should be configured on a Gnosis Safe with 1/N threshold (fast response), while the upgrade role should be on a Safe with N/M threshold (slow, secure changes). This approach secures funds even during an active attack.

Common Node Issues and Their Solutions

Geth stuck on a block:

# Diagnose via debug_traceBlockByNumber curl -s -X POST localhost:8545 \ -d '{"jsonrpc":"2.0","method":"debug_traceBlockByNumber","params":["latest",{}],"id":1}' # If node hangs—restart with --gcmode archive and --syncmode full # If state corruption—resync from checkpoint geth snapshot prune-state 

Consensus client sees no peers—check iptables and libp2p address configuration. op-batcher doesn't publish batches—check batcher wallet balance and L1 RPC availability.

Outsourcing vs In-House Support

Criteria In-house team Our support
Cost Salaries of 2–3 engineers + bonuses Fixed monthly fee, no overpay. Our Production support starts at $2,500/month.
Expertise Limited to team stack Broad expertise across L1/L2, Solana, tooling, with certified engineers.
Response time Depends on workload SLA from 15 minutes to 4 hours, guaranteed.
Monitoring Basic (CPU/RAM) Full stack: on-chain, nodes, validators.
Updates Asynchronous Planned + urgent hotfixes.

Our service suits projects aiming to reduce support costs by 30–50% without quality loss. The support budget is on average 40% lower than maintaining an in-house team of two engineers (which costs $15k–25k per month). Savings can range from $5,000 to $20,000 per month depending on project complexity.

Service Level Agreements and Support Models

Level Response time Coverage Best for
Basic monitoring — / no on-call 9×5 business hours Testnet, pre-launch
Standard 4h critical, 24h other 5×12 Mainnet with low TVL
Production 30 min critical, 4h other 7×24 Mainnet with active users
Enterprise 15 min critical, 1h other 7×24 + dedicated DeFi protocols, infrastructure

For projects with TVL > $1M and live users, the minimum reasonable level is Production. We'll help you choose the optimal SLA—get a consultation to discuss your project.

How We Evaluate Your Project and Provide an Estimate

Our evaluation process consists of several steps:

  1. Data collection: We gather information about your infrastructure—node types, smart contract architecture, RPC providers, team size.
  2. Audit/Analysis: We review your current monitoring, incident response plans, and update procedures.
  3. Design: We propose a support plan tailored to your needs, including SLA, monitoring scope, and incident response runbook.
  4. Estimation: Based on complexity, we provide a fixed monthly fee—no hidden costs.
  5. Development: We set up monitoring dashboards, alert rules, and automate incident response.
  6. Testing: We run simulations to ensure everything works.
  7. Launch: We go live with 24/7 monitoring and support.

Timeline Estimates

Typical timelines from initial contact to full support:

  • Basic setup (standard monitoring, no custom runbooks): 1–2 weeks.
  • Full production support (custom dashboards, runbooks, SLA): 2–4 weeks.
  • Enterprise with dedicated team and advanced automation: 4–6 weeks.

Exact timelines depend on project complexity and availability of information.
