Not Sure Which NFT Standard to Choose?

NFT Architecture: What Lives On-Chain and What Doesn’t
1
Smart contract — ownership, minting, royalties
Smart contracts manage token ownership, minting, transfers, and royalty details. The main NFT logic stays on-chain and cannot be changed once deployed.
2
Metadata storage — IPFS, Arweave, or on-chain
NFT metadata and media can be stored with IPFS, Arweave, or directly on-chain. The best option depends on cost, how permanent the data needs to be, and the level of decentralization you want.
3
Minting frontend — UX that doesn’t lose users
Frontend apps manage wallet connections, minting steps, transaction updates, and errors. The minting process should stay simple for users, even when blockchain actions happen behind the scenes.
4
Backend services — indexing, notifications, admin
Backend systems handle indexing, notifications, allowlist management, and admin features. Common tools are The Graph, webhook services, and dashboards for managing collections.
NFT Security: Common Vulnerabilities We Prevent
Reentrancy on mint
We use ReentrancyGuard and secure transaction patterns to protect the minting process.
Unauthorized minting / access control
AccessControl, allowlists, and Merkle proof validation help prevent unauthorized minting.
Metadata manipulation
Protection includes provenance hash validation, frozen metadata, and IPFS pinning strategies.
Royalty bypass
EIP-2981 royalty logic and operator filter mechanisms help enforce creator royalties.
Rug pull / owner drain
Using multisig ownership, timelocks, and limited admin permissions helps reduce the risk of rug pulls.
Our approach: audit every NFT contract
Manual review, Slither analysis, fuzzing, and re-audit after fixes are included as part of NFT smart contract audit workflows.
NFT Tech Stack
Smart Contract
Solidity 0.8+, ERC-721A, ERC-1155, and EIP-2981 standards for NFT collections, minting, and royalty logic. Our development process relies on tools like Foundry, Hardhat, OpenZeppelin, and Thirdweb.
Metadata & Storage
We store NFT metadata and media files using IPFS and Arweave. For fully on-chain generative collections, we also support on-chain SVG.
Frontend & Minting
We build mint pages, wallet connections, and transaction handling with React, Next.js, ethers.js, and wagmi. RainbowKit and WalletConnect help make user onboarding easier.
Infrastructure
Alchemy, Moralis, The Graph, and Tenderly help us with indexing, monitoring, notifications, and other NFT infrastructure needs.
Chains
We use Ethereum, Polygon, Solana, Arbitrum, and Base to support NFT collections, marketplaces, gaming, and membership products.
Ready to Launch Your NFT Project?
Discuss NFT architecture, minting strategy, royalties, and blockchain selection before development starts.
From Concept to Mint
Week 1–2 — Discovery & Standard Selection
During this phase, we define project requirements, choose the right NFT standard, plan the minting flow, and set the gas budget. The result is a clear NFT specification and metadata structure.
Week 3–4 — Contract Architecture & Art Pipeline
We set up smart contract logic, royalties, reveal mechanics, and prepare the metadata flow. If the collection is generative, we also prepare the art generation pipeline.
Week 5–8 — Development & Metadata Setup
We develop the NFT smart contracts, build the minting frontend, and upload metadata to IPFS or Arweave. This stage also includes setting up the allowlist and deploying to the testnet.
Week 9–10 — Audit & Testnet Launch
We audit, test, and fix the NFT smart contracts before launch. At the end of this phase, we provide an audit report and release the project on the public testnet.
Week 11 — Mainnet Deployment & Mint Event
We handle mainnet deployment, support the mint launch, monitor the project, and provide post-launch updates. This also includes verifying royalties and tracking activity on secondary markets.

FAQs
1. What is NFT smart contract development?
What is NFT smart contract development?
NFT smart contract development is the process of creating blockchain contracts that handle NFT ownership, minting, transfers, royalties, and marketplace features. Depending on your project, this could involve ERC-721 collections, ERC-1155 gaming assets, staking systems, or custom NFT features.
2. ERC-721 vs ERC-1155: which should I use?
ERC-721 vs ERC-1155: which should I use?
ERC-721 is usually the better choice for unique NFTs like PFP collections, digital art, or collectibles where each token is different. ERC-1155 is better for gaming assets, memberships, tickets, or projects that need both fungible and non-fungible tokens in one contract.
3. How much does NFT smart contract development cost?
How much does NFT smart contract development cost?
Costs usually range from $5,000 to over $50,000, depending on the type of NFT, minting process, marketplace features, and blockchain used. Simple collections are less expensive, while marketplaces, staking, and gaming features take more time and cost more.
4. How long does it take?
How long does it take?
A basic NFT collection usually takes about 4 to 6 weeks, including minting and deployment. More complex projects like marketplaces, staking platforms, or gaming systems can take 8 to 12 weeks or more, depending on the details.
5. How do you ensure on-chain royalty enforcement?
How do you ensure on-chain royalty enforcement?
Royalties are managed using EIP-2981 and custom revenue split logic. Extra marketplace features can be added to help make sure creators keep getting royalties after launch.
6. Which chains do you support for NFTs?
Which chains do you support for NFTs?
NFTs can be built on Ethereum, Polygon, Solana, Arbitrum, or Base. The best option depends on transaction fees, marketplace options, speed, and your target audience.NFTs can be built on Ethereum, Polygon, Solana, Arbitrum, or Base. The best option depends on transaction fees, marketplace options, speed, and your target audience.
7. Where should metadata be stored?
Where should metadata be stored?
IPFS is popular for decentralized storage at a low cost. Arweave is often used for permanent storage. Fully on-chain metadata is usually only used for smaller or generative collections because it costs more.
8. Can you audit existing NFT contracts?
Can you audit existing NFT contracts?
Yes. We can review existing ERC-721 and ERC-1155 contracts for minting issues, royalty problems, metadata risks, and access control. The audit can also include suggestions to improve security and contract design.
9. Do you build NFT marketplaces?
Do you build NFT marketplaces?
Yes. We can build NFT marketplaces with listings, auctions, escrow, wallet integration, royalty distribution, and admin features. Both the smart contracts and the frontend app can be developed in the same project.
10. How to get started?
How to get started?
We usually start by discussing your NFT project’s standards, minting process, royalties, and chain choice. Then, we prepare a proposal with the scope, timeline, and next steps based on your needs.
