Chain Config Service

Code Source: src/services/chain-config/service.ts

Overview

The ChainConfigService provides a unified interface for querying blockchain configurations. It abstracts the complexity of chainConfigStore and provides helper methods for adapters.

Core Capabilities

1. Configuration Access

• getConfig(chainId): Retrieves the full ChainConfig object.
• getDecimals(chainId), getSymbol(chainId): Quick access to chain metadata.

2. API Discovery

The service implements a pattern-based API discovery mechanism to support various provider types:

• getApi(chainId): Returns all available API endpoints.
• getRpcUrl(chainId): Finds the primary RPC endpoint (matches *-rpc).
• getBiowalletApi(chainId): Finds BioWallet-specific APIs (matches biowallet-*).
• getEtherscanApi(chainId): Finds block explorer APIs.

3. Explorer Integration

Provides template-based URL generation for:

• Transaction links: getTxQueryUrl
• Address links: getAddressQueryUrl

Usage Example

import { chainConfigService } from '@/services/chain-config';

// Get RPC URL for a chain
const rpcUrl = chainConfigService.getRpcUrl('ethereum');

// Get decimals
const decimals = chainConfigService.getDecimals('bfmeta');
