Blockchain Development .
iSkylar builds production-grade blockchain solutions, from smart contract development and DApp architecture to tokenisation platforms and private enterprise blockchain networks. Whether you are building on Ethereum, Solana, or Hyperledger, our team delivers audited, scalable code backed by the security standards that blockchain applications demand.
What We Build
Smart Contract Development
We design, write, test, and audit smart contracts on Ethereum, Polygon, BNB Chain, and Solana — covering DeFi protocols, NFT contracts, DAO governance, escrow logic, and token standards (ERC-20, ERC-721, ERC-1155).
Decentralised Application (DApp) Development
Full-stack DApp development — Web3 frontend with wallet connectivity (MetaMask, WalletConnect), smart contract backend, and IPFS or Arweave storage where decentralised persistence is required.
Tokenisation Platforms
We build token launch infrastructure — ERC-20 and SPL token creation, vesting schedules, liquidity pool integration, and tokenomics implementation for utility tokens, security tokens, and NFT collections.
Private & Enterprise Blockchain
Permissioned blockchain networks on Hyperledger Fabric or Quorum for supply chain, trade finance, healthcare records, and enterprise data integrity use cases — where public chain visibility is not appropriate.
Blockchain Integration & APIs
We build middleware layers that connect your existing web applications and databases to on-chain data — indexing events, reading state, and writing transactions without requiring your team to become blockchain engineers.
Smart Contract Auditing
Independent security review of smart contract code — reentrancy, overflow, access control, and logic vulnerability analysis — with a formal audit report before any mainnet deployment.
Delivered faster with AI tooling
We don't just write code; we orchestrate intelligence. By integrating Copilot-assisted generation and AI-driven automated testing, we reduce time-to-market by up to 40%.
LLM-backed development to eliminate boilerplate delays.
Anticipating edge cases before they enter production.
The iSkylar Tech Stack
Our Development Journey
A streamlined, transparent path from vision to launch.
Discovery & Architecture
1–2 weeks
We define the on-chain logic, off-chain data model, wallet integration approach, and network selection — and produce a technical spec reviewed before any contract is written.
Smart Contract Development
2–6 weeks
Contracts written in Solidity or Rust, tested on a local hardhat/Foundry fork, and deployed to testnet for your review. Every function tested against the specification before mainnet.
Frontend & Integration Build
2–6 weeks
Web3 frontend connecting wallet, reading contract state, and submitting transactions — alongside any backend indexing or API layer required for your application logic.
Security Audit
1–2 weeks
Independent review of all contract code covering reentrancy, integer overflow, access control, front-running, and logic vulnerabilities. Audit report delivered before mainnet deployment.
Mainnet Deployment
3–5 days
Contracts deployed to mainnet with multi-sig admin controls, contract verification on Etherscan or equivalent explorer, and monitoring set up for on-chain events.
Maintenance & Upgrades
Ongoing
On-chain monitoring, incident response for contract anomalies, and upgrade path management using proxy patterns where upgradeability was designed in.
Our Proven Track Record

Enterprise blockchain networks deployed for supply chain and trade finance clients
Flexible Engagement
Partnership structures tailored to your scale and velocity.
Smart Contract Package
Smart contract development, testnet deployment, unit tests, and a security audit report. Ideal for teams who need audited on-chain logic without a full DApp build.
- Defined Scope
- Fixed Budget
Full DApp Build
End-to-end — smart contracts, Web3 frontend, wallet integration, backend indexing, security audit, mainnet deployment, and 3 months of post-launch support. Our most popular engagement.
- Full Integration
- Infinite Scalability
Blockchain Retainer
A dedicated blockchain engineer or security specialist on a monthly retainer for ongoing development, protocol upgrades, and smart contract monitoring.
- Defined Scope
- Fixed Budget

Frequently Asked Questions
Which blockchain networks do you build on?+
We primarily build on Ethereum and EVM-compatible chains (Polygon, BNB Chain, Arbitrum, Base) for smart contracts and DeFi, Solana for high-throughput use cases, and Hyperledger Fabric for permissioned enterprise networks. We advise on the right chain based on your throughput, cost, and privacy requirements.
Do you audit smart contracts before mainnet deployment?+
Yes — every smart contract engagement includes a security audit phase. We review for reentrancy, integer overflow, access control vulnerabilities, logic errors, and front-running exposure, and deliver a formal audit report before any mainnet deployment.
How long does blockchain development take?+
A smart contract package with audit is typically 4–8 weeks. A full DApp with frontend, integration, and audit runs 12–20 weeks. Timeline depends on contract complexity and integration scope.
What does blockchain development cost?+
Smart contract packages start from $8,000. Full DApp builds from $28,000. Pricing depends on contract complexity, number of integrations, and audit scope. Fixed-scope quote before signing.
Can you integrate blockchain into our existing application?+
Yes. We build middleware and indexing layers that expose on-chain data and transaction submission through standard REST APIs — so your existing frontend or backend can interact with the blockchain without requiring a full rewrite.
What happens if a bug is found in a deployed smart contract?+
If upgradeability was designed in (proxy pattern), we can push a fix. For immutable contracts, the mitigation depends on what was affected — we advise on the safest path during the audit phase. This is why audit-before-mainnet is non-negotiable on every engagement.
Who owns the smart contract code?+
You do. All Solidity or Rust source code, test suites, deployment scripts, and audit reports are fully transferred at project close.
Do you provide post-launch monitoring?+
Yes. We set up on-chain event monitoring and alerting, and offer incident response retainers for production contracts handling significant value.
