# Developer Overview ### Contract Overview The Capsule Protocol utilizes three main Ethereum contracts to perform all of its on-chain functions. * [**Capsule NFT contract**](/capsulenft/developer-walkthroughs/contracts/capsule.sol.md) * [**CapsuleFactory contract**](/capsulenft/developer-walkthroughs/contracts/capsulefactory.sol.md) * [**CapsuleMinter contract**](/capsulenft/developer-walkthroughs/contracts/capsuleminter.sol.md) The *CapsuleMinter* and *CapsuleFactory* contracts are attached to a proxy contract, meaning they are upgradable. The *Capsule NFT* contract can be 'upgraded' by changing the deploy address. This allows future Collections to support much greater functionality, such as storing other token types or storing combinations of other tokens. {% hint style="info" %} For more information on the *contracts utilized in the Capsule Protocol*, please read [Contracts](/capsulenft/developer-walkthroughs/contracts.md). {% endhint %} ### Developer Walkthroughs Walkthroughs of which methods to use when incorporating the Capsule Protocol in your application can be found in [Developer Walkthroughs](/capsulenft/developer-walkthroughs.md). The example scenarios that are covered include: * [User wants to mint any type of Capsule NFT](/capsulenft/developer-walkthroughs/developer-mint-a-capsule-nft.md) * [User wants to redeem any type of Capsule NFT](/capsulenft/developer-walkthroughs/developer-redeem-a-capsule-nft.md) * [User wants to create a Capsule Collection](/capsulenft/developer-walkthroughs/developer-create-a-capsule-collection.md) * [User wants to manage their created Capsule Collection](/capsulenft/developer-walkthroughs/developer-managing-a-capsule-collection.md) ### Decentralization All Capsule Protocol contracts are decentralized. If the Capsule Team vanished tomorrow, the ecosystem would continue to work exactly as coded. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
