@jointlabs/chains-info v0.0.54

Chains Info

This repository includes information about the chains and payment methods supported by the Joint Interface, Indexer and other components of the Joint ecosystem. It is meant to be the source of truth for chain metadata.

Usage

import chains,{getChainByName} from '@jointlabs/chains-info'

Usage with NextJS

import chains,{getChainByName} from '@jointlabs/chains-info/next'

Add /next to the import path to use the NextJS version of the library. This version will use process.env to set the chain information but still outputs an ESM module.

Environment Variables

All environment variables allow a prefix (denoted as {PREFIX}) to be set to match the prefix used by the host framework (e.g. NextJS = NEXT_PUBLIC_, Vite = VITE_). If no prefix is set, the environment variable name is used as is.

Chains Information

src/chains.ts contains the relevant information about the supported chains. This includes basic metadata (name, symbol, etc), It also includes fields such as contract address, rpc and indexer url that are set through environment variables. While most fields require a value passed through environment variables, the contract addresses for non-localhost chains have real default values.

Environment Variables

Tokens Lists

src/token_list.ts includes the token list for each chain. It is used by the indexer to determine which tokens to index. It is also used by the Joint Interface to display the tokens supported by each chain.

Payment Methods

src/payment_methods.ts contains all the payment methods supported. It includes the full badge name, region and logo.

Mediator Pools

src/mediator_pools.ts contains the mediator pools supported by the Joint Interface. It is used to display the pools available for each chain, allowing ticket purchasers to select the pool they want to join after purchasing a ticket.

Badge Manifest

src/badge_manifest.ts contains the information about badges that can be claimed on a Joint Interface.

Environment Variables

ABI

src/abi/index.ts contains the ABI for the contracts used by the Joint Interface and services. It is paired with web3 packages viem or ethers.js to facilitate interactions with Joint contracts.
