/**
 * Blockchain Address Derivation Utilities
 * Derives addresses for multiple blockchains from a single FLO/BTC WIF private key
 *
 * Supported Blockchains:
 * - FLO - via floCrypto (base blockchain)
 * - BTC (Bitcoin) - via btcOperator
 * - ETH (Ethereum) - via floEthereum
 * - AVAX (Avalanche C-Chain) - same as ETH (EVM-compatible)
 * - BSC (Binance Smart Chain) - same as ETH (EVM-compatible)
 * - MATIC (Polygon) - same as ETH (EVM-compatible)
 * - ARB (Arbitrum) - same as ETH (EVM-compatible)
 * - OP (Optimism) - same as ETH (EVM-compatible)
 * - HBAR (Hedera) - same as ETH (EVM-compatible)
 * - XRP (Ripple) - via xrpl library
 * - SUI - via nacl + BLAKE2b
 * - TON - via nacl + TonWeb
 * - TRON - via TronWeb
 * - DOGE - via bitjs with version byte 0x1e
 * - LTC (Litecoin) - via bitjs with version byte 0x30
 * - BCH (Bitcoin Cash) - via bitjs with version byte 0x00 + CashAddr format
 * - DOT (Polkadot) - via @polkadot/util-crypto with SS58 encoding
 * - ALGO (Algorand) - via nacl + SHA-512/256 with Base32 encoding
 * - XLM (Stellar) - via nacl + CRC16-XModem with Base32 encoding
 * - SOL (Solana) - via Ed25519 + Base58 encoding
 * - ADA (Cardano) - via cardanoCrypto library (https://cdn.jsdelivr.net/gh/void-57/cardano-wallet-test@main/cardano-crypto.iife.js)
 *
 * Dependencies :
 * - bitjs (for WIF decoding)
 * - Crypto.util (for hex/bytes conversion)
 * - xrpl (for XRP)
 * - nacl/TweetNaCl (for SUI, TON, ALGO, XLM)
 * - TonWeb (for TON)
 * - TronWeb (for TRON)
 * - @polkadot/util-crypto (for DOT)
 * - @polkadot/util (for DOT)
 * - js-sha512 (for ALGO)
 * - @solana/web3.js (for SOL)
 * - cardanoCrypto (for ADA)
