Solidity is the main programming language for smart contracts on Ethereum and other EVM-compatible chains. A smart contract is code that stores state and executes agreed rules on the blockchain without an intermediary. As a Solidity development company, Sigmato builds the contracts and the applications around them, following the language’s official documentation.
Contracts are hard to change once deployed and often hold real value, so correctness matters more than speed. We write small, readable contracts, test them thoroughly and plan for an independent review before launch.
Solidity Development Services
Smart contract development
Custom contracts written in Solidity for tokens, vesting, staking, escrow, voting and business logic.
NFT and token contracts
ERC-20, ERC-721 and ERC-1155 contracts with minting, royalties and access rules. See our NFT marketplaces.
dApp development
Web and mobile front ends that connect wallets to your contracts, with the backend services around them.
Testing and audit preparation
Unit, integration and fuzz tests, gas checks and a pre-audit review. Read about smart contract audits.
DeFi and tokenization
Exchange, lending and asset-tokenization logic. See real-world asset tokenization.
Upgrades and maintenance
Proxy upgrade patterns, monitoring and fixes for contracts you already run.
Use Cases for Solidity Smart Contracts
- Decentralised exchanges. Transparent trading of tokens and other assets.
- Supply chain tracking. Shared records of goods movement and automatic payment on milestones.
- Identity verification. Credentials that users control, reducing intermediaries.
- Voting systems. Tamper-evident voting for organisations and DAOs.
- Prediction markets. Platforms where participants trade on outcomes.

Our Smart Contract Development Process
- Requirements and threat model. We define the rules, roles and what could go wrong.
- Design. Contract architecture, upgrade strategy and which parts stay off-chain.
- Implementation. Solidity code using proven libraries such as OpenZeppelin, in a framework like Hardhat or Foundry.
- Testing. Automated tests, testnet deployment and gas optimisation.
- Audit and deployment. Independent review, then mainnet launch with monitoring.
Solidity vs Other Smart Contract Platforms
| Platform | Language | Consider it when |
|---|---|---|
| Ethereum and EVM chains | Solidity | You want the largest developer and tooling ecosystem |
| Solana | Rust | You need very high throughput; see our Solana platform page |
| Cardano | Plutus and others | You prefer its formal-methods approach; see Cardano |
Not sure which fits? Our comparison of Solana vs Ethereum explains the trade-offs, and our Solidity best practices cover how we write contracts.
Why Choose Sigmato for Solidity Development
- Security first. Checks-effects-interactions, access control, and attention to well-known vulnerabilities.
- Readable code. Solidity’s JavaScript-like syntax makes contracts easier to review when kept simple.
- Full product delivery. Contracts, dApp and backend from one team, as part of our decentralised platforms work.
- Honest advice. If you do not need a blockchain, we say so.
- Dedicated engineers. You can also hire blockchain developers from India.

Frequently Asked Questions
What is Solidity used for?
Solidity is used to write smart contracts for Ethereum and EVM-compatible blockchains, covering tokens, NFTs, DeFi protocols, DAOs and other on-chain logic.
Is Solidity hard to learn?
It is a high-level, object-oriented language with syntax similar to JavaScript, so web developers pick it up quickly. Writing secure contracts takes extra care and experience.
Do smart contracts need an audit?
If a contract holds value, an independent audit is strongly recommended. We prepare code for audit and fix findings.
Which blockchains can you deploy to?
Ethereum and EVM-compatible networks such as Polygon, Arbitrum, Optimism and BNB Chain, using the same Solidity skills.
Can you fix or upgrade my existing contract?
Deployed contracts cannot be edited, but we can review them, deploy fixed versions, migrate state and add upgradeable patterns where suitable.
