I will deploy a custom nft smart contract on ethereum with onchain metadata
Ezenwanne Ikech
About this gig
Looking to launch your own NFT collection? I will deploy a custom ERC-721 NFT smart contract tailored to your project.
What makes my service unique:
On-chain SVG metadata no IPFS, artwork lives directly on the blockchain
Custom name, symbol, and supply
Minting functions with max supply and mint price controls
Clean, well-structured Solidity code
Foundry-tested contracts (Premium)
Full source code provided
Why work with me:
I built a fully on-chain NFT collection with SVG metadata and Base64 encoding as part of my advanced smart contract training. No copy-paste code every contract is written, tested, and deployed properly.
On-chain metadata means your NFT artwork and attributes are stored permanently on the blockchain not on a server that can go down.
Message me before ordering if you have custom requirements and I'll let you know if it fits your project.
Keep your assets and information safe.
NFT services focus solely on developing and programming.
Never share sensitive information with others, and make sure you own all required rights to the underlying asset. Read about NFTs on Fiverr

FAQ
What information do I need from you to get started?
I need your collection name, symbol, total supply, and whether you want on-chain SVG metadata or a base URI for external metadata.
What is on-chain SVG metadata?
It means your NFT artwork and attributes are stored directly on the blockchain — not on IPFS or a server. Your NFTs will exist forever even if external services go down.
Can you deploy on networks other than Ethereum?
Yes, I can deploy on any EVM-compatible chain like Polygon, BNB Chain, or Arbitrum. Message me first to confirm.
