An SDK to fetch and filter chain information

This repo and product is intentionally managed as Open Source and we aim to use this guide to light our way https://opensource.guide/. Let us know how we are doing!

🔨 Install

npm install @ixo/cosmos-chain-resolver

yarn add  @ixo/cosmos-chain-resolver

💻 Usage

To use the Cosmos Chain Resolver, you can import the function(s) you want to use and execute it with the appropriate parameters.

import {
	getRegistryChainInfo,
	getActiveRpcFromRegistryChainInfo,
	getActiveRpcFromChainName,
	getChainExplorer,
	getChainExplorerAsync,
	getKeplrChainInfoFromRegistryChainInfo,
	getKeplrChainInfo,
} from '@ixo/cosmos-chain-resolver';

The Cosmos Chain Resolver SDK expose the following functions:

getRegistryChainInfo

getRegistryChainInfo(chainName: string, chainNetwork?: ChainNetwork): Promise<RegistryChainInfo>

This function fetches the chain info for the provided chainName and chainNetwork. If chainNetwork is not provided, it defaults to mainnet.

getActiveRpcFromRegistryChainInfo

getActiveRpcFromRegistryChainInfo(chainInfo: RegistryChainInfo): Promise<string>

This function filters through and fetches an active RPC endpoint from the provided chainInfo.

getActiveRpcFromChainName

getActiveRpcFromChainName(chainName: string, chainNetwork?: ChainNetwork): Promise<string>

This function fetches an active RPC endpoint for the provided chainName and chainNetwork. If chainNetwork is not provided, it defaults to mainnet.

getChainExplorer

getChainExplorer(chainName: string, chainNetwork: ChainNetwork, chainExplorers?: ChainExplorer[]): KeplrChainExplorer | undefined

This function fetches the tx explorer info for the provided chainName, chainNetwork and chainExplorers.

getChainExplorerAsync

getChainExplorerAsync(chainName: string, chainNetwork: ChainNetwork): Promise<KeplrChainExplorer | undefined>

This function fetches the tx explorer info for the provided chainName and chainNetwork via the Cosmos Chain Registry.

getKeplrChainInfoFromRegistryChainInfo

getKeplrChainInfoFromRegistryChainInfo(chainInfo: RegistryChainInfo): Promise<KeplrChainInfo>

This function fetches the keplr chain info for the provided chainInfo.

getKeplrChainInfo

getKeplrChainInfo(chainNameOrId: string, chainNetwork: ChainNetwork = MAINNET, ): Promise<KeplrChainInfo>

This function fetches the keplr chain info for the provided chain id or the chain name-and-network.

📱 Example

import { getKeplrChainInfo } from '@ixo/cosmos-chain-resolver';

// fetch chain info via chain id
const ixoKeplrChainInfo = await getKeplrChainInfo('ixo-5');

// fetch chain info via chain name and network
const ixoTestnetKeplrChainInfo = await getKeplrChainInfo('impacthub', 'testnet');

import { getRegistryChainInfo, getKeplrChainInfoFromRegistryChainInfo } from '@ixo/cosmos-chain-resolver';

// fetch chain info via chain id
const ixoRegistryChainInfo = await getRegistryChainInfo('impacthub', 'mainnet');

// fetch chain info via chain name and network
const ixoKeplrChainInfo = await getKeplrChainInfoFromRegistryChainInfo(ixoRegistryChainInfo);
