Blockchain Development Services Our Developers Provide
Hire blockchain developers from CMARIX to build secure, scalable, purpose-built decentralized and enterprise blockchain products.
Smart Contract Development
We create smart contracts for decentralized products and business processes. Our team develops tokens, escrow, staking, governance, marketplace, vesting, subscription, rewards, treasuries, and custom protocol contracts. In EVM ecosystems, we use Solidity and popular libraries, along with testing, static analysis, fuzzing, and secure deployment practices.
Decentralized Application (dApp) Development
We develop fully decentralized applications, integrating smart contract logic with user-friendly web and mobile interfaces. Our skills include wallet connections, smart contract interaction, transaction signing, on-chain data, off-chain services, token balances, user dashboards, notifications, indexing, and analytics. We use the latest web front-end frameworks, including React, Next.js, and Vue.js.
Ethereum & EVM Blockchain Development
We build production-ready apps for Ethereum and Ethereum Virtual Machine (EVM)-compatible chains like BNB Smart Chain, Polygon, Avalanche, Base, Arbitrum, and Optimism. These include Solidity smart contracts, ERC standards, wallets, Ethereum JSON-RPC, account abstraction, Layer 2 deployment, oracles, indexing, decentralized storage, and multisig management.
Solana Blockchain Development
We develop highly optimized decentralized and on-chain applications for Solana using Rust, Anchor, and Program Derived Addresses. Our team handles cross-program invocation, SPL Tokens, Token Extensions, Wallets, Solana RPC, and Account Design. We optimize our applications around the limitations of the Solana platform.
Enterprise & Private Blockchain Development
We build permissioned blockchain solutions for businesses that need restricted membership, confidentiality, and governance capabilities. Applications range from supply chain coordination and asset tracking to business document management, identity management, intercompany processes, audit trails, and document validation. We build solutions using technologies such as Hyperledger Fabric because its permissioned network architecture suits their needs.
Hyperledger Fabric Development
We build enterprise blockchain networks using Hyperledger Fabric. Our capabilities span Go, Node.js, and Java chaincode; channels; membership services; private data; endorsement policies; Fabric Gateway; and network deployment. This framework is highly relevant for organizations that need to transact on a shared ledger with configurable identity and governance.
DeFi Platform Development
The team develops decentralized financial applications, including lending and borrowing, staking, swapping, liquidity pools, yield operations, vaults, governance, and treasury functionalities. The DeFi development process includes thorough threat modeling, economic tests, oracle-risk assessments, access control checks, and security audits before committing any significant value to DeFi applications.
Decentralized Exchange Development
We provide customized DEX services, such as token swaps, liquidity pools, AMM algorithms, routing, slippage management, fee structures, wallets, analytics, and governance capabilities. Our developers evaluate existing protocols rather than blindly copying them, ensuring everything aligns with your economic and security expectations.
Blockchain Wallet Development
We build secure blockchain wallet applications and integrations that support multi-chain tracking, token balances, transaction history, transaction signing, WalletConnect, hardware wallets, key recovery, multisig, MPC, and fiat on-ramps. Our wallet architecture begins with a clear decision between custodial, non-custodial, multisig, smart-account, or MPC-based models.
NFT Marketplace Development
Our developers build NFT and digital asset marketplaces, with capabilities covering minting, listings, offers, auctions, royalties, wallet integration, metadata, collections, search, and admin tools. CMARIX's blockchain experience spans 30+ NFT marketplace deployments. Every NFT implementation follows the selected blockchain's latest token standards and marketplace requirements.
Tokenization & Digital Asset Development
We tokenize digital and physical assets into technical formats for ownership, transfer limitations, minting, burning, governance, compliance, custody, and off-chain legal rights. We create fungible tokens, NFTs, membership tokens, loyalty tokens, digital certificates, and tokenized documents. Creating tokens technologically does not necessarily create the legal rights represented by the token.
DAO & Blockchain Governance Development
Our governance systems operate in on-chain and hybrid settings, including proposal creation, voting, delegations, timelocks, treasury management, multi-sigs, roles, and governance analytics. When AI supports governance analytics or proposal drafting, we clearly outline the human decision-making that follows.
Cross-Chain Integration & Bridge Development
We build interoperability functionalities within ecosystems including cross-chain messages, asset swaps, contract orchestration, oracle communication, and multi-chain design. Because bridges increase the attack surface across contracts, relays, validators, message protocols, and custody systems, we focus on independent security assessment, monitoring, rate limiting, emergency measures, and incident response.
Supply Chain Blockchain Development
We develop blockchain traceability solutions when multiple interested parties need the same information. Examples of blockchain use for traceability include product origins, batches, suppliers, delivery incidents, certifications, documents, and audits. In our opinion, use blockchain only when its advantage over a database is clear.
Blockchain Node, API & Infrastructure Development
We develop and operate the infrastructure behind blockchain applications, including RPC integration, nodes, indexers, event processors, backend APIs, webhooks, blockchain listeners, data pipelines, monitoring, and transaction relayers. Infrastructure setups can use suitable managed or self-hosted node environments based on your technical needs.
AI-Powered Blockchain Application Development
We integrate blockchain technology with AI workflows to enable autonomous agent transactions, verify AI activities, and support decentralized identity and data provenance. We design AI governance, automated smart contract execution, and intelligent Web3 interfaces. To make our systems secure, we follow the principle of limited permissions, isolate private keys, set transaction limits, require human approvals, and build failure-recovery mechanisms.
Token Launch & ICO Technology Development
We develop the technical infrastructure required for compliant token-launch initiatives, including token contracts, vesting, allocation, distribution, whitelisting, wallet integration, administrative tools, and investor portals. Because token sales may be subject to securities, financial, tax, AML/KYC, or consumer-protection regulations depending on jurisdiction and structure, validate applicable legal choices with qualified professional counsel.
Blockchain Migration & Modernization
We modernize existing blockchain applications by reviewing smart contracts, protocol dependencies, SDKs, frontend libraries, RPC infrastructure, wallet integrations, indexers, security, gas consumption, and deployment processes. Our migration services also include safely moving application functionality to a different blockchain network whenever business and technical requirements justify the change.
Blockchain Support & Maintenance
Our team maintains production blockchain systems through continuous smart-contract monitoring, node monitoring, RPC tracking, dependency upgrades, security fixes, frontend updates, wallet compatibility maintenance, gas optimization, infrastructure support, and incident investigation. We ensure your distributed systems remain safe, online, and performant 24/7.
