Cardano Developer Portal

The official Cardano Developer Portal -by the Cardano Foundation- providing both new and seasoned developers with the resources to be successful on Cardano.

The Cardano Foundation has created this developer portal with both aspiring and veteran developers in mind. Here developers can find resources that introduce them to:

Cardano and its underlying technologies
Integrating Cardano into existing services
Project Catalyst and how to access project funding through it
Stake pool operations and their requirements
Cardano Native Tokens and how to create them (including NFTs)
Smart contracts on Cardano, and resources for learning the languages they're written in
Metadata, how to use it, and it's use cases

The Cardano Developer Portal is packed full of helpful and informational links to other resources, including Cardano developer tools, that are all useful in assisting developers in their desires to learn about and build on Cardano.

NFT

If you’re looking for a Cardano NFT then you’ve found the place for you! listed here are all the projects that feature NFTs in some form on Cardano. NFTs are no longer just the PFP collections that made them famous, although many do still exists and you can find Cardano NFT projects here, NFTs are assets with multiple different types of utility, depending on which project’s NFTs your buying.

A Cardano NFT is a native asset on Cardano which means that, unlike on other (specifically EVM-based) chains, an NFT is not managed by a smart contract, meaning that it behaves and is managed differently to the chain’s base asset, ada. On Cardano NFTs behave the same as the chains base asset as they are native to the chain.

On this page you’ll find everything from Cardano NFT projects to DeFi projects and decentralized identity (DID) solutions that have incorporated NFTs, to the Cardano NFT marketplaces you can use to purchase NFTs.

Metadata

Metadata is an element of a Cardano transaction that can be inputed by the user or automatically generated. It is stored on the blockchain with the transaction that it was sent with. This means that, just like the transactions themselves, metadata is immutable, i.e. unchangeable, and stored forever on the Cardano blockchain.

Anyone can add metadata into a transaction and that metadata is then stored on the blockchain. Many wallets allow you to add custom metadata to a transaction.

Metadata can only be made up of characters i.e. numbers, letters and punctuation, and cannot be a file type, i.e. you cannot unload files like PDFs or MP3s to the blockchain. The size of the metadata you can add to a transactions is limited to 16KB, and a character is, typically, 1 Byte, so that means you can add up to 1600 characters as metadata with any transaction.

Metadata can be used for many purposes the most common is to give some form of context to the transaction. Metadata has been used to store supply chain data, to send arbitrary message to be stored on the blockchain, and to store the hash of a document (allowing the blockchain to be used for proof-of-existence). People have used metadata, on the testnet, to immortalize the Cardano whitepaper, by writing it onto the blockchain as transactions across multiple transactions.

Many block explorers allow users to view and search transaction metadata. Remember, anything you add as metadata to a transaction will always be publicly available on the blockchain.

Developer Tools

If you’re a Cardano developer looking for the tools to develop a project or the resources for learning about developing on Cardano - such as Cardano developer courses - then you’ve come to the right place! Here you’ll find NFT tools for the Cardano NFT developer, project deployment resources for the Cardano app developer, community translations of the official Cardano wallet library into various other programing languages, APIs, SDKs, oracles, open source smart contract libraries, and community created tools and resources for the Cardano developer of today.
