Where We've Shipped Smart Contracts

Our smart contract development services cover the sectors where automation, transparency, and trust are critical — here's the on-chain logic we've shipped in each.

DeFi lending & borrowing

automated collateralization, interest, and liquidation logic without intermediaries.

Payment & settlement

on-chain transaction processing with traceable, accurate settlement.

Asset tokenization

financial assets on-chain with clear ownership, transfer and compliance rules.

Compliance automation

permissioning, transaction limits and audit-ready data flows.

NFT & DeFi Smart Contract Development

We design smart contract development solutions across the two areas where most on-chain work happens—each built to the standards and security patterns it demands.
01

NFT Smart Contract Development

As an NFT smart contract development company, we build ERC-721 and ERC-1155 contracts with lazy minting, on-chain royalties via EIP-2981, full marketplace logic and IPFS-backed metadata, plus custom mint mechanics and allowlists where you need them.
02

DeFi Smart Contract Development

As a DeFi smart contract development company, we build AMMs and liquidity pools, manipulation-resistant oracles, liquidation engines, staking and yield mechanics, and flash-loan logic — each designed for economic security under adversarial conditions.
03

Decentralized Exchanges (DEX)

Core DEX logic — AMMs, order books, liquidity provisioning, fee distribution and settlement — built for high volume and resistance to front-running.
04

Digital Wallet Contracts

Contracts for custodial and non-custodial wallets: secure asset management, transaction validation and permission control with strict access boundaries.
05

DAO Contracts

Governance frameworks, voting systems, treasury management and proposal execution — built for transparency and predictable decentralized decisions.

What Usually Goes Alongside a Web3 Build

Smart contracts are the on-chain core, but a working Web3 product needs more around them:

From Spec to Mainnet

Our smart contract development process is built to catch problems before they reach a chain where code is immutable. Timelines below are typical ranges — the exact plan depends on protocol complexity and audit scope.
Step 01

Requirements & Architecture

Usually 1–2 weeks. We analyze business logic, protocol goals, and security risks, then define contract behavior, interactions, and the target chain.

  • Protocol requirements and specs
  • Architecture and interaction model
  • Threat model and risk assessment
  • Platform and tooling selection
Step 02

Contract Design

Around 1 week. Requirements become a detailed blueprint — data structures, permission models, and execution flows for predictable access control.

  • Interface definitions
  • Data models and storage layout
  • Access-control and role design
  • State-transition diagrams
Step 03

Development

Typically 3–6 weeks depending on scope. Contracts are implemented with secure coding practices — correctness, modularity, and readability for clean auditing.

  • Implemented contract codebase
  • Modular components and libraries
  • Inline documentation
  • Deployment scripts
Step 04

Testing & Internal Audit

Runs alongside development, 2–3 weeks. This is where security is proven — unit and invariant tests, Slither and Foundry analysis, and an internal security review before any external auditor.

  • Unit, integration, and invariant tests
  • Edge-case and failure validation
  • Slither / Foundry static analysis
  • Pre-audit report for the external auditor
Step 05

External Audit & Remediation

1–3 weeks, scheduled before mainnet. We prepare the codebase for a third-party audit, then remediate every finding and re-test.

  • Audit preparation package
  • Remediation of findings
  • Re-testing and verification
  • Final audit sign-off
Step 06

Deployment & Support

Mainnet launch and beyond. Controlled, repeatable deployment with verified addresses, monitoring, and ongoing gas optimization.

  • Deployment artifacts and verified addresses
  • Post-deployment monitoring
  • Gas optimization
  • Upgrade and maintenance plan

The developers from Incora completed all the work with very high quality and on time. They participated in architecture and software design. I was especially impressed by their ability to learn new areas of applications and become productive quickly. Incora has provided very good developers for our projects. They has impressed us with the personal attention and effectiveness of their account managers. When a new project comes Incora is the first company I contact.

Incora has been great at understanding our company and the work we want to do. They took the time to understand who we were and didn’t rush or make suggestions that didn’t make sense. They keep delivering what they promise and are very helpful and easy to work with — there haven't been any complications. I don't think there's anything they can improve on — they’re getting better and better over time. Just tell them what you want, and they'll try to work around your expectations.

Incora has been fantastic to work with. I find them very professional, ethical, and, responsible. I’ve worked with many developers, but Team Incora has been outstanding. This team understands what you need and what you want, and delivers on both fronts very effectively. Highly recommend working with them if you get a chance…

CEO at EnviaYa

We’ve hired a programmer from Incora, who is working on all our plug-ins. We initially worked on a Magento 1 plug-in, then moved on to Magento 2 and PrestaShop ones. I’m very happy with the one developer we’ve been assigned, who is doing a great job. He can think for himself, mention any details we may have overlooked and basically correct requirements. Incora's developer takes initiative, completes work promptly, and produces high-quality deliverables at all times.

Volodymyr and Mark (ed: Incora developers) are quite smart and greate programmers. I have worked with more than 100 programmers and done more than 20 software projects. Both are top 10% of people I have worked with.

FAQ About Smart Contract Development

How much does a smart contract audit cost?

An external audit typically runs $5,000–30,000+ depending on contract complexity and lines of code, while our internal review with Slither, Foundry, and invariant tests is included in development. As a DeFi smart contract development company, we ship a pre-audit report so the external audit costs less and finds less.

Which blockchain should we build on?

It depends on your users and cost model. Ethereum suits high-value DeFi and NFT projects; Polygon and Base cut gas for consumer apps; Solana fits high-throughput use cases. Our smart contracts development services start with a platform assessment against your throughput, cost, and security needs.

Do you provide security audits?

Yes — every contract goes through manual review, Slither and Foundry static analysis, and invariant testing, covering reentrancy, access-control flaws, and logic errors. As a smart contract development company, we deliver a pre-audit report and remediation guidance before you engage a third-party auditor.

How long does smart contract development take?

Simple contracts take a few weeks; complex DeFi protocols or DAO governance run 2–4 months, including testing and external audit. We prioritize correctness and security over speed, since mainnet code is immutable and a rushed contract is expensive.

What happens if a vulnerability is found after deployment?

It depends on the architecture. Immutable contracts can't be changed, which is why we use upgrade-aware patterns like proxies where future fixes may be needed. For critical issues, we build pause mechanisms and controlled migration paths from the start, so every finding has a safe response.

Do you build NFT smart contracts?

Yes — as an NFT smart contract development company, we build ERC-721 and ERC-1155 contracts with lazy minting, on-chain royalties via EIP-2981, marketplace logic, and IPFS-backed metadata. That covers everything from a single collection to a full marketplace with custom mint mechanics.

Do you build DeFi protocols?

Yes — we build AMMs, liquidity pools, staking, lending, and liquidation logic, with manipulation-resistant oracles and flash-loan handling. We design every DeFi contract for economic security and exploit resistance, because the contract holds real value and every edge case is an attack surface.

Can you audit contracts we already deployed?

Yes — we provide independent audits of live contracts covering manual review, static analysis, and vulnerability detection, with remediation guidance for every finding. You get a prioritized report — critical to informational — plus gas and maintainability recommendations.

Who owns the code and the deploy keys?

You do — full IP ownership of the codebase transfers to you, and we hand over deploy keys, admin roles, and ownership on delivery. We recommend a multi-sig or your own key-management setup for mainnet, so your team retains full control of the contract.
