Popular blockchain networks we work with

Ethereum

+

Leading smart contract platform enabling decentralized application development. Ethereum offers rich developer tooling ecosystem, token standards (ERC-20, ERC-721), and the largest developer community.

Binance Smart Chain (BNB Chain)

+

Fast and cheap alternative to Ethereum, compatible with Ethereum Virtual Machine. BSC offers low transaction costs and high throughput for DeFi applications.

Polygon

+

Layer 2 scaling solution for Ethereum, offering fast and cheap transactions. Polygon supports various scaling technologies including PoS chains and zkEVM.

Solana

+

High-performance blockchain with unique Proof of History architecture, enabling thousands of transactions per second. Solana is ideal for high-throughput applications.

Avalanche

+

Three-chain architecture blockchain offering fast transaction finality and custom subnet creation capabilities. Avalanche is Ethereum-compatible.

Cardano

+

Research-driven blockchain using Proof of Stake consensus mechanism. Cardano offers a sustainable and secure platform for smart contracts.

Polkadot

+

Multi-chain blockchain enabling interoperability between different networks. Polkadot allows creating specialized blockchains (parachains) connected to the main network.

Near Protocol

+

User-friendly blockchain with sharded architecture, offering ease of use and low costs. Near supports smart contracts in Rust and AssemblyScript.

Arbitrum

+

Optimistic rollup Layer 2 for Ethereum, offering significantly lower gas costs while maintaining Ethereum compatibility. Arbitrum is ideal for DeFi applications.

Fantom

+

Fast and scalable blockchain using Lachesis consensus, offering instant transaction finality. Fantom is compatible with Ethereum Virtual Machine.

Cosmos

+

Ecosystem of interoperable blockchains called the "internet of blockchains". Cosmos enables creating custom blockchains with Inter-Blockchain Communication Protocol.

Chainlink

+

Decentralized Oracle Network connecting smart contracts with real-world data. Chainlink provides secure and reliable external data sources for blockchain applications.

Tron

+

Entertainment and content sharing focused blockchain, offering high throughput and low costs. Tron supports smart contracts and decentralized applications.

Hyperledger Fabric

+

Enterprise-grade blockchain framework for business applications, offering permissioned network architecture and modular structure for corporate use cases.

Smart contracts for a wide range of sectors

Our smart contract development services find applications across various industries and use cases

DeFi Protocols

+

We develop lending/borrowing contracts, AMM protocols, yield farming systems, liquidity mining contracts, and advanced DeFi composability solutions.

NFTs and Digital Assets

+

We create ERC-721/ERC-1155 contracts, NFT marketplaces, royalty systems, metadata management, and dynamic NFT functionalities with on-chain logic.

Token Economics

+

We implement ERC-20 tokens, governance tokens, staking contracts, vesting schedules, token distribution mechanisms, and deflationary/inflationary models.

Gaming and Metaverse

+

We build game asset contracts, in-game economies, breeding mechanisms, battle systems, virtual land management, and play-to-earn reward systems.

Supply Chain

+

We develop traceability contracts, authenticity verification, quality assurance systems, logistics tracking, and sustainability certification protocols.

Real Estate

+

We create property tokenization contracts, fractional ownership systems, rent collection automation, property management, and real estate investment protocols.

Insurance

+

We implement parametric insurance, automated claims processing, risk pooling contracts, premium calculation systems, and decentralized insurance markets.

Identity and Credentials

+

We build identity verification contracts, credential issuance systems, reputation mechanisms, KYC/AML compliance, and self-sovereign identity solutions.

Marketplace and E-commerce

+

We develop decentralized marketplaces, escrow systems, dispute resolution contracts, payment processing, and seller reputation management systems.

Corporate Governance

+

We create voting contracts, proposal systems, treasury management, shareholder rights management, and transparent corporate decision-making protocols.

What is the smart contracts development process?

1

Requirements analysis and specification

We analyze business requirements, define smart contract functionalities, determine interactions with other contracts, and plan system architecture.

2

Contract architecture design

We design data structures, define functions and modifiers, plan upgrade patterns, access control mechanisms, and gas optimization strategies.

3

Implementation in Solidity/Rust

We code smart contracts using best practices, implement business logic, error handling, event logging, and integrations with external protocols.

4

Unit testing and integration

We write comprehensive test suites, conduct unit testing, integration testing, mock external dependencies, and test edge cases and failure scenarios.

5

Security audits

We conduct internal code reviews, external security audits, vulnerability assessments, reentrancy protection testing, and formal verification where applicable.

6

Deployment and verification

We deploy to testnet, conduct final testing, deploy to mainnet, verify source code on block explorers, and configure monitoring systems.

7

Maintenance and upgrades

We monitor contract performance, implement upgrades through proxy patterns, manage governance changes, and provide ongoing technical support.
