Why did my wallet address change?

Each digital asset in your wallet has a unique address assigned to it. For BSV, BTC, BCH, and LTC, a new address is assigned after each use. ERC-20 tokens issued on the Ethereum blockchain (ETH, USDC, SHIB, BAT, LINK, LRC, XRP, USDT, and ZRX), have static addresses for each asset that do not change.
