Welcome to the FrostySDK

A developer toolkit for building NFT-based applications via simple JavaScript functions.

Endeavoring to build towards a future where NFTs are not just digital collectibles, but a foundation upon which to build artist-owned applications. The FrostySDK enables you to rapidly deploy and interact with myriad smart contracts to create your own Web3 ecosystem powered by NFTs. We prioritized ease-of-use and composability so that you can do more with less, leading to accelerating and compounding innovation.

The FrostySDK is currently deployed to Ethereum, Arbitrum, Optimism, zkSync, Polygon and each chain's primary testnet. We hope that you enjoy using the SDK and encourage developers to contribute new modules via pull requests and post updates and issues in the repository's discussion forum.

Core Modules

FRSTSDK
This contract serves as a permanent, immutable, and permissionless foundation upon which to build your application. Its primary function is to allow artist-owned and gas-efficient deployments of the core contracts within the FrostySDK.

NFT Release & Utility Mechanisms

We refer to Edition, Rentable, and Crescnedo as Base contracts, defined as release mechanisms that generate the root unit of exchange in a community. The Vault and Staking modules are Wrapper contracts, meaning they can be used to add utility to either a new or exisitng NFT collection. Vault-Backed is a Hybrid contract; it leverages both the Edition or Rentable module plus the Vault module to enable both a base and wrapper contract to be deployed in a single transaction.

Base and hybrid contracts support the NFT Royalty Standard (EIP2981).

Edition
NFT drop utilzing the gas-optimized ERC721A which allows minting multiple NFTs for nearly the cost of one.
ZKEdition
An extension of Frosty's gas-optimized ERC721A which allows minting multiple NFTs for nearly the cost of one. ZKEditions enable people to collect NFTs while preserving their privacy.
Rentable
An extension to Edition implementing ERC4907A / EIP4907, which allows a token's owner to grant time restricted user rights to another account.
Crescendo
NFT drop utilizing a gas-optimzed version of ERC1155 with bonding curves to enable dynamic pricing for fan powered price discovery and guarantee liquidity to collectors.
Vault
A time-locked vault to distribute ERC20 tokens to owners of an ERC721 or ERC4907 collection at expiry based on their percentage of ownership in the collection.
Staking
A staking vault allowing owners of an ERC721 or ERC4907 collection to stake their NFTs and earn ERC20 tokens distributed based on the length of the lock up.
VaultBackedNFT
A module to simplify the process of launching a Vault-Backed NFT into a single transaction, allowing you to deploy either an Edition or Rentable which will be automatically backed by a shared Vault.

Marketplace Modules

RentalMarket
A rental marketplace allowing instant daily rentals for Rentable or any other NFT which implements the EIP4907 standard.

Infrastructure Modules

Registry
The Registry serves as a public on-chain record of all contracts deployed via the FrostySDK and as a point of entry for the Frosty Cross-Chain Indexer (please reach out to a Frosty team member for access to the indexer).
MetadataRenderer
A shared on-chain metadata renderer adhering to the music metadata standard which stores and renders metadata as base64 encoded URLs.
IPFS
Simplifies the process of uploading files and metadata to IPFS, allowing you to generate IPFS URLs for media files such as images, audio, and video, as well as metadata json files.
