Let’s make this simple. Imagine traveling across countries, each with its own currency. Instead of carrying separate wallets for euros, dollars, and yen, you have one smart wallet that automatically works everywhere. That’s a multi-chain wallet in crypto terms. A multi-chain wallet lets you store, send, and receive assets across multiple blockchain networks like Ethereum, Binance Smart Chain, Avalanche, Polygon, Solana, and others all in one place.
