Backpack Wallet

Multi-chain wallet by Coral with xNFT support and full compatibility with KingSwap.

What is Backpack?

Backpack is a non-custodial wallet created by Coral, the team behind the Anchor framework and xNFT standard. It was originally designed for Solana but has expanded to support Ethereum, Polygon, and other chains. Backpack is known for its clean interface, integrated NFT marketplace, and the xNFT system — executable NFT applications that run inside the wallet.

Like Phantom and Solflare, Backpack stores your keys locally. Every transaction is signed on your device, and KingSwap never has access to your funds. Backpack follows the Solana Wallet Standard, which means it works with any dApp that supports the standard — including KingSwap.

Security best practices

Never share your recovery phrase. Store it offline. Verify every transaction before signing. Use a hardware wallet for large balances. Backpack is non-custodial, so you alone are responsible for protecting your keys.
