The Internet of Blockchains. Cosmos is an ever-expanding ecosystem of interconnected apps and services, built for a decentralized future. Enter a new universe of connected services. Cosmos apps and services connect using IBC, the Inter-Blockchain Communication protocol. This innovation enables you to freely exchange assets and data across sovereign decentralized blockchains. Serving as the economic center of Cosmos, the Cosmos Hub is a blockchain that provides vital services to the Interchain. Set to operate a next-gen decentralized exchange, swapping digital assets from across the Interchain, with very low fees and instant transaction confirmation. With the upcoming Interchain Staking feature, ATOM will soon be securing many chains, in exchange for additional staking rewards. A core mission of the Hub – to connect chains by establishing IBC connections with compatible chains and operating decentralized bridges with chains like Ethereum and Bitcoin.

The first interoperable Layer 1 for NFTs. NFT launchpad, NFT marketplace, community-owned, zero gas, carbon neutral (proof-of-stake), secured by 100+ validators. Programmable via CosmWasm, interoperable via Cosmos IBC, Ethereum interoperability via Gravity Bridge. Setting up your project for minting is done via a set of command-line tools. Start by cloning a sample repository, and replacing it with your project contents. Stargaze's sg721 contract allows for off-chain metadata storage. We recommend using a decentralized storage solution such as IPFS. Stargaze NFT metadata follows the OpenSea metadata standards. Create directories to hold images and metadata, and then compile them into a single IPFS CAR (Content Addressable aRchive) file that can be uploaded. After getting the CID for metadata, you set it as the base URL in your contract. This way, the contract knows how to associate each token ID with an individual token URI without having to send the contract a list of URIs.
