The short answer
Smart contract development is the process of writing, testing and launching small programs that run on a blockchain. Each program holds the rules of an agreement. It runs on its own when those rules are met, so no bank or broker is needed. Most smart contracts are written in Solidity, Rust or Move.
Business terms, such as who pays whom, when and on what condition, are turned into code.
The contract is published to a blockchain and gets a permanent address.
A transaction, a date, or real-world data from an oracle meets the condition.
The contract moves funds, mints tokens or updates records, and the result is stored on-chain where anyone can verify it.
Quick facts
Here are the key facts we share with every client before a smart contract project starts. They cover cost, timeline, languages, networks and security. Use them to compare quotes and plans from any vendor before you sign. Your final numbers depend on your scope, chain and audit needs.
What we do
Code Brew offers blockchain smart contract development services for every stage of your project. We help you plan the contract, write the code, test it and keep it safe after launch. You can hire us for one service or for the full build.
We help you choose the right chain, token model and upgrade plan before coding starts. Our blockchain consulting team turns your idea into a clear technical spec.
We write every contract around your business rules, not a copied template. The code uses trusted OpenZeppelin libraries and is covered by automated tests.
We review new or existing contracts line by line and run automated scans. You get a report that ranks every issue by risk, with a clear fix plan.
Gas is the fee users pay to run each transaction. We rewrite costly functions and storage so your users pay less every time they use your product.
Upgradeable contracts let you fix or improve logic without losing stored data. We use proven proxy patterns, protected by multisig wallets and time delays.
Oracles are trusted data feeds that bring outside information on-chain. We connect your contracts to prices, weather or any API using Chainlink, Pyth or custom oracles.
Your users may hold assets on more than one network. We build secure bridge and messaging contracts that move tokens and data between chains.
Moving to a new chain or version should not put funds at risk. We carry balances and contract state across safely and verify every step.
A live contract still needs care after launch. We watch it on-chain, send real-time alerts and handle upgrades or incidents when they happen.
Contract types
Code Brew builds twelve common types of smart contracts. Each type follows its own token standard and carries its own security risks. Our smart contract services match the build and the audit to what your contract must protect. Each card below shows the standards we use.
Fungible tokens power payments, rewards and governance. We build them with the mint, burn, pause and tax rules your business needs.
NFTs prove ownership of a unique digital item. We build collections with built-in creator royalties, lazy minting and allowlists.
Permissioned tokens let only approved investors hold and trade an asset. They are the base of compliant asset tokenization.
Property can be split into tokens that many investors own. We automate rent payouts and hold deposits in on-chain escrow.
Stablecoins hold a steady value against a currency like the US dollar. We build mint, redeem and reserve check logic with freeze controls.
DeFi contracts run lending, trading and staking without a bank. We build these decentralized finance solutions with tested, audit-ready logic.
Exchanges need fast and fair trade settlement. We build order book, liquidity pool and settlement contracts tested against common trading attacks.
A token launch needs clear rules for sale and release. We build presale, vesting, airdrop and claim contracts your investors can check.
Escrow contracts hold funds until agreed work is done. Payments release on their own at each milestone, with no middleman.
A DAO lets token holders vote on decisions together. We build voting, treasury and timelock contracts that keep every decision on record.
Smart wallets make crypto easier for everyday users. We build multisig and ERC-4337 wallets with gasless transactions and social recovery.
Every decentralized app needs on-chain logic behind its screens. We build the contracts that connect your users, wallets and data.

Industries
Code Brew builds smart contracts for any business that moves money, assets or records between parties. Each contract is shaped around how your industry works and the rules it must follow. Here is what our contracts automate in each sector.
Banks and decentralized finance platforms use smart contracts to settle payments faster. We build lending, settlement and KYC-gated transfer logic.
Property deals involve many parties and long waits. Our contracts split ownership, pay out rent and hold deposits in on-chain escrow.
Real-world assets like bonds and funds can be issued as tokens. We add investor whitelists and automatic dividend payouts.
Parametric policies pay out when set data is reached, such as a flight delay. Claims settle faster with less paperwork.
Every handover in a supply chain can be recorded on-chain. Payment releases on its own when delivery is confirmed.
Healthcare data needs strict access rules. We build contracts for drug traceability and patient-approved record access.
Players want to truly own what they earn. We build contracts for in-game assets, NFT marketplaces and reward payouts.
Retailers can accept crypto and reward loyal customers with tokens. Refunds can run on their own when set rules are met.
Energy can be traded directly between producers and users. We build contracts for peer-to-peer trading, carbon credits and billing.
Public records need to be open and hard to change. We build contracts for land registries, grants and transparent voting.
Why it pays off
Smart contracts remove cost and delay from processes that depend on trust. When the rules live in code, nobody needs to chase payments or check ledgers by hand. Here is what your business gains when Code Brew builds them for you.
Remove brokers, escrow agents and manual reconciliation.
Transactions complete in seconds or minutes, not days.
Every action is recorded on a shared ledger anyone can verify.
Once deployed, no single party can quietly change the rules.
Payments, payouts and compliance checks run on their own.
Code executes exactly as written, every time.
KYC, transfer limits and jurisdiction rules built into the contract.
Works 24/7 across borders.
A traditional contract describes what should happen and relies on people to do it. A smart contract makes it happen on its own. Here is how the two compare on the points that matter most to a business.
| Factor | Smart contractRules enforced by code | Traditional contractRules enforced by people |
|---|---|---|
| Execution | Automatic, by code | Manual, by people |
| Intermediaries | None needed | Lawyers, banks, brokers |
| Settlement time | Seconds to minutes | Days to weeks |
| Transparency | Public, verifiable record | Private copies |
| Cost per transaction | Low (network fee) | High (fees + admin) |
| Changes | Only via pre-built upgrade rules | Renegotiation and paperwork |
| Enforcement | Self-enforcing | Courts or arbitration |
Networks
There is no single best blockchain for every smart contract. Ethereum and its Layer 2 networks offer the widest tools and liquidity. Solana and BNB Chain offer low fees and high speed. Code Brew helps you choose based on your users, budget and compliance needs.

Video review Talk to a blockchain architect directly. No sales script, just answers.
A smart contract development company designs, codes, tests and deploys smart contracts for businesses.
It also supports those contracts after launch. A good partner like Code Brew advises you on blockchain choice, token model, upgrade plan and compliance before any code is written. This helps you avoid costly changes later.
The programming language used for smart contracts depends on the blockchain.
Solidity is the most common and runs on Ethereum and other EVM chains. Solana uses Rust, while Aptos and Sui use Move. TON uses FunC or Tact, and Cardano uses Plutus or Aiken. We pick the language that fits your network.
The best blockchain for smart contracts depends on your goal.
Ethereum and its Layer 2 networks offer the most liquidity and integrations. Solana, Polygon and BNB Chain offer lower fees and faster transactions. TON suits apps built for Telegram users. Our architects recommend one after a short discovery call.
Yes, smart contracts can use real-world data through oracles.
An oracle is a trusted data feed that brings outside information on-chain. Services such as Chainlink and Pyth supply prices, weather, sports results or other API data. We set up and test these feeds so your contract reacts to accurate information.
Yes, we can integrate smart contracts with your existing app or ERP.
Our smart contract integration work connects contracts to web and mobile apps, ERPs like SAP and CRMs like Salesforce. We use event listeners, indexers and secure APIs. Your team then sees on-chain activity inside the tools it already uses.
The token standard you should use depends on what the token represents.
ERC-20 suits payment and reward tokens. ERC-721 and ERC-1155 suit NFTs and game items. ERC-4626 suits yield vaults, and ERC-3643 suits regulated securities. We confirm the right standard during discovery, based on your wallets, exchanges and compliance needs.
Smart contract development services usually cost between $5,000 and $100,000+.
A simple token contract starts around $5,000. DeFi protocols, RWA platforms and projects with external audits cost more. The final price depends on contract count, chain, integrations and audit depth. We share a fixed quote after a free discovery call.
Developing a smart contract takes 2 weeks to 6 months, depending on scope.
A simple token takes 2 to 4 weeks. Staking contracts or NFT marketplaces take 4 to 8 weeks. Complex DeFi or enterprise systems take 2 to 6 months, including audits. We give you a week-by-week plan before work starts.
Gas fees are what users pay the network to run each transaction, and yes, we can reduce them.
We optimize storage, batch operations and remove wasteful code. For high-volume apps, we may also suggest a lower-cost chain or Layer 2 network. Lower gas costs make your product cheaper and easier to use.
A standard smart contract cannot be changed after deployment.
An upgradeable contract can be, because it uses a proxy pattern. The proxy lets you update the logic while keeping all stored data. We protect every upgrade with a multisig wallet and a time delay, so no single person can change the rules.
We make sure a smart contract is secure with a 7-layer process.
It covers threat modelling, secure coding, automated scans, full testing, fuzz testing and an independent manual review. Before launch, we coordinate a third-party audit where needed. After launch, we monitor the contract on-chain with real-time alerts.
You need a third-party smart contract audit if your contract will hold user funds, or if you plan to raise money or list a token.
Investors, exchanges and users expect an independent report. We coordinate with an established smart contract audit company and fix every finding before launch.
Yes, we can audit or fix a smart contract built by another team.
We review the existing code, test it and report each issue by severity. Then we can fix, migrate or redeploy the contract. This works well before a launch, a token listing or a funding round.
Whether smart contracts are legally binding depends on your country and how the agreement is set up.
A smart contract can support or carry out a legal agreement. Many countries recognise electronic contracts, but the rules differ. We work alongside your legal advisors so the code matches the legal terms.
Smart contracts need to comply with MiCA or VARA if you serve users in the EU or Dubai and your token falls under those rules.
Contracts can enforce controls such as whitelists, transfer limits and freeze roles. Your legal counsel confirms the classification, and we build the controls into the code.
You own the smart contract code we build for you.
At handover, we transfer the intellectual property, source code, documentation and admin keys. Nothing stays locked with us. You can maintain the code with your own team or with any partner you choose.
Yes, we provide support after deployment through a maintenance plan.
It covers on-chain monitoring, planned upgrades, gas optimization and incident response. You choose the level of support that fits your product. This keeps your contracts safe as usage grows and networks change.
