Usage

Network Management

import { networks } from '@safeblock/blockchain-utils';

console.log(networks);

Address Utilities

import { isSpecialAddress, validateAddress } from '@safeblock/blockchain-utils/address';

const address = '0x...';

// Check if an address is special
console.log(isSpecialAddress(address));

// Validate the address format
console.log(validateAddress(address));

The Address Utilities module also supports:

• Address Type Checks: Easily determine if an address is valid or matches specific criteria.
• Address Actions: Includes functions for address formatting and manipulation.

Amount Utilities

import { parseAmount, formatAmount } from '@safeblock/blockchain-utils/amount';

// Parse an amount string to a standardized object
const parsedAmount = parseAmount('1.23');
console.log(parsedAmount);

// Format an amount object for display
const formattedAmount = formatAmount(parsedAmount);
console.log(formattedAmount);

The Amount Utilities module supports:

• Parsing amounts from strings into objects.
• Formatting amounts for user-friendly display.
• Validating amounts to ensure accuracy.

Ethers Provider

import { createFallbackProvider, reconfigureProviders } from '@safeblock/blockchain-utils/ethers-provider';

// Create a fallback provider with a list of nodes
const provider = createFallbackProvider(['https://mainnet.infura.io', 'https://cloudflare-eth.com']);

// Dynamically update the provider list
reconfigureProviders(provider, ['https://new-node1.com', 'https://new-node2.com']);

The Ethers Provider module supports:

• Fallback mechanisms for reliable provider access.
• Reconfiguring provider lists dynamically without restarting the application.
