Smart contracts are immutable by default. Once deployed, flawed logic doesn't just sit there — it waits to be exploited. A single reentrancy gap, an unchecked access control, or an integer overflow can drain user funds in minutes, permanently.
That is why every engagement at Blockchains Specialist starts with an architecture review, not a code sprint.
We are a dedicated smart contract development company with 8+ years of hands-on Solidity and Rust experience across Ethereum, BNB Chain, Solana, Polygon, Arbitrum, and more. Our contracts are scoped, written, tested, and security-reviewed from scratch on every project. No boilerplates. No name swaps. No shortcuts.
Book a Free Technical ConsultationEvery engagement is scoped from scratch. These are the core disciplines we cover.
ERC-20, ERC-721, ERC-1155, BEP-20, and fully custom contract logic built to your exact specification. Every contract is written for your use case, not adapted from a template library.
Staking pools, yield farming vaults, liquidity protocols, lending markets, and AMM integrations. Multi-contract DeFi systems are our standard scope. We understand the attack surface that comes with user funds at scale.
Gas-optimized Solidity written to OpenZeppelin standards. Upgradeable proxy patterns — both transparent and UUPS — available for projects requiring post-deployment logic flexibility without redeployment risk.
From scoping and architecture through testnet deployment, security review, third-party audit coordination, and mainnet launch. One team, one handoff. No gaps, no finger-pointing between contractors.
Internal security assessment on every engagement — covering reentrancy vectors, access control gaps, arithmetic overflow, front-running exposure, and logic vulnerabilities. Third-party audits via CertiK, SlowMist, and OpenZeppelin available.
ERC-721 and ERC-1155 contracts for NFT collections, dynamic metadata, on-chain royalties, and marketplace integrations. Full audit support included for launch-critical NFT projects.
Proxy migrations, contract refactoring, and legacy codebase remediation. If you inherited broken code from a previous team or a freelancer, we assess, fix, and redeploy — with full documentation.
We work with founders and teams who understand that smart contract quality is non-negotiable.
Who need a smart contract developer they can hold accountable — not a Fiverr contractor who disappears after delivery.
That need remediation before their exchange listing. We assess, fix, and re-submit with a clean audit report.
Integrating blockchain smart contract development into existing product infrastructure with strict compliance and documentation requirements.
Who received a rejected or exploitable contract from a previous developer and need a clean, audited replacement built from scratch.
Most development teams add a security review at the end. We build it in from the start. Every contract leaves our hands only after passing our internal security checklist.
For projects handling user funds, we coordinate third-party audits with the same firms used by the top DeFi protocols. We manage the process — you get the report.
Our Tooling
Industry-leading smart contract security firm
Blockchain security specialists
The gold standard in contract security
Every function has unit tests. Testnet deployment is mandatory before mainnet. You receive full source code, ABI files, deployment scripts, and Etherscan verification on delivery.
We deploy on the chains your users are already on.
Other networks evaluated on request.
Seven disciplined stages from scope to mainnet — no shortcuts, no handoff gaps.
We review your use case, architecture requirements, and security constraints before a single line of code is written. Scope is locked before work begins.
System design, contract interaction maps, and upgrade strategy defined and documented. You approve the architecture before development starts.
Contracts written in Solidity or Rust depending on chain. Every function is covered by unit tests using Hardhat or Foundry. No untested logic enters review.
Full internal audit against our security checklist. Identified issues remediated before the contract reaches your team or any external auditor.
Full testnet deployment with transaction evidence. Client review period before mainnet is approved.
For DeFi protocols, token launches, and projects handling user funds, we coordinate with CertiK, SlowMist, or OpenZeppelin. We manage the communication and remediation cycle.
Final deployment to mainnet with Etherscan source verification, ABI delivery, and deployment documentation. Ongoing support available post-launch.
The difference between a typical smart contract shop and an architecture-first development partner.
| What Others Do | What We Do |
|---|---|
| Send you a modified template | Scope and write from scratch every time |
| Add security review as an afterthought | Build security into the architecture from Day 1 |
| Hand off code with no tests | Deliver full unit test coverage with every contract |
| Leave audit coordination to you | Manage third-party audit process end-to-end |
| Disappear after deployment | Available for post-launch upgrades and support |
75+ blockchain projects delivered. Zero mainnet exploits on contracts built from scratch by our team.
A standard token contract typically takes 3–7 days. A full DeFi protocol with multiple interdependent contracts and audit coordination runs 3–6 weeks. We scope timelines accurately on the first call with no surprise delays.
Yes. We review, audit, and remediate contracts built by other teams or freelancers. If you have a deployed contract with identified issues, or a legacy codebase that needs upgrading before a listing or launch, we assess and fix.
Ethereum, BNB Chain, Solana, Polygon, Arbitrum, Avalanche, Base, and Tron. Additional networks are evaluated on request.
Yes. We implement OpenZeppelin transparent proxy and UUPS proxy patterns for projects that require post-deployment logic upgrades without full redeployment.
Full source code with inline documentation, ABI files, deployment scripts, testnet and mainnet transaction hashes, Etherscan source verification, and an internal security review report. Third-party audit reports included where applicable.
Yes. We serve clients globally, including active engagements in the UAE and Dubai market. Our blockchain smart contract development services are fully remote and timezone-flexible.
Project-based pricing scoped after a technical review call. No hourly surprise billing. Scope and price locked before work begins.
We review your requirements, flag any architecture risks, and give you an honest scope and timeline estimate. No commitment required on the first call.
