SubWallet-Chain

This is the repository to integrate, contain all information about projects/chains/assets available on SubWallet's products.

Scope of this project

• Provide a coherent schema and interfaces for projects/chains/assets across blockchains
• Showing relationships between projects/chains/assets
• Track development status
• Provide metadata/on-chain information about chains and assets
• Provide general, non-tech information (website, description, social media,...) about chains and assets
• Allowing partners/teams to easily integrate with SubWallet products

Note: The current interfaces and json files do not necessarily follow this exact schema. The schema demonstrates the abstraction and relationships of the data

Explanation

• Chain: A blockchain, can be Polkadot, Kusama, Ethereum,...
• EVM_Chain, SUBSTRATE_CHAIN: blockchain type, contains technical information about a blockchain, a blockchain can be a mix between many types
• Chain asset: a token, NFT collection,... that originates from a blockchain
• Multichain asset: a high-level abstraction representation of an asset across many blockchains, it might have an on-chain origin or not
• Asset reference: showing path in which an asset can be converted to another
• Project: products for end-user building upon a blockchain, can be a dApp, a media team,...
