From deep tech to fast launches - teams trust us to deliver complex blockchain systems securely, on time, and with confidence

CIDT superhero symbolizing client success and project results
Web3 Survey Monetization App

CIDT led the end-to-end development of Emet Earn, a platform where users can sign up, complete surveys, and license their responses using the UDL framework to earn passive income. We were responsible for the entire product setup, including UI/UX design, technical architecture, user story definition, full-stack implementation, infrastructure, and integrations with blockchain and decentralized storage systems like Arweave.

IBC integration with Avalanche

To connect Avalanche Layer 1 with the Cosmos ecosystem, we built and deployed light clients, a relayer, and a robust tech stack. The result: a scalable cross-chain bridge completed on schedule.

Avalaunch LBP

CIDT led the full-cycle development of the first version of Avalaunch’s LBP (Liquidity Bootstrapping Pool) platform, delivering smart contracts, frontend and backend logic, infrastructure, and post-launch support. We implemented key user features including LBP creation flows, listing, pool pages, swap mechanics, and realtime token updates. The smart contract layer included integrations with Balancer, a forked Copper launch module, Gnosis Safe, and Trader Joe. Our team also deployed Subgraph indexing, and set up CI/CD pipelines and production infrastructure for launch.

DefiMons

CIDT supported the DeFiMons team by delivering critical smart contract components and DevOps infrastructure to power their Web3-enabled monster taming MMORPG. We implemented a range of game-specific smart contracts including apartment systems, monster marketplaces, and cross-chain transfers using LayerZero. Our team also designed and executed comprehensive stress testing of the subnet-EVM (both locally and on Avalanche Fuji), deployed Prometheus and Grafana-based monitoring, and established dashboards to monitor EVM status and validator health in real time.

GnosisSafe (Gnosis)

CIDT developed WebAssembly-based SDK wrappers for the Safe and SafeFactory contracts using Polywrap. These wrappers enable seamless integration of Gnosis Safe functionality into Web3 applications via modular, upgradeable components. We also built a demo app showcasing their usage in real-world frontend environments.

Pairwyse Protocol

CIDT was a core contributor to the development of Pairwyse Protocol, a decentralized framework for trustless DAO-to-DAO interactions and smart contract lifecycle management. We implemented the full suite of smart contracts and on-chain logic enabling immutable governance, peer-to-peer risk product issuance, protocol-to-protocol lending, and DAO mergers — all without centralized intermediaries. Pairwyse extends smart contract functionality with constitutional enforcement, rights management, and on-chain due diligence to enable programmable, interoperable financial and governance instruments.

How We Work

Clear process. Predictable delivery. Real results
01

Agile Planning (First 3-4 weeks)

Before writing a single line of code, we align on everything that matters - from product vision to blockchain architecture.

  • Storyboarding & user journey mapping
  • Technical discovery and architecture design (EVM or non-EVM)
  • Tokenomics validation and smart contract concepts
  • UI/UX prototyping for your DApp or dashboard
  • Agile estimation and team setup
  • Proof of concept or testnet deployment (if needed)

Outcome: a clear delivery plan, realistic timeline, and confidence that your blockchain MVP or protocol module is built on solid technical foundations.

02

Sprint Delivery (Every 2 Weeks)

Each sprint brings measurable progress - and a UAT-ready blockchain build.

  • Sprint planning & backlog prioritization
  • Design and smart contract development (Solidity / Rust)
  • Integration with oracles, wallets, or bridges
  • Manual and automated QA testing
  • Internal review + client demo
  • Deployment to testnet or mainnet-ready environment

Outcome: working software every sprint - whether it’s a DeFi protocol, NFT marketplace, or enterprise blockchain module.

03

Post-Launch Support

We stay with you after release to ensure long-term reliability and scalability.

  • Continuous monitoring of on-chain activity and performance
  • Critical issue resolution and incident response
  • DevOps, infrastructure & CI/CD pipeline management
  • Product and roadmap planning for new features
  • Emergency response for bridge or protocol security events

Outcome: your Web3 product stays secure, stable, and ready to scale.

04

Continuous Improvement

We continuously refine both the product and the process.

  • End-of-sprint demos and retrospectives
  • Backlog grooming with your input
  • Regular status reports and roadmap reviews
  • Smart contract and infrastructure optimization cycles

For us, working software and measurable outcomes are the only KPIs that matter - not hours logged.
