QUESTIONS & ANSWERS

Frequently Asked Questions

What is Web3?+
Web3 refers to the next generation of the internet built on blockchain technology. It emphasizes decentralization, user ownership of data, peer-to-peer interactions without intermediaries, and self-custody of digital assets through cryptographic wallets like Backpack.
How does Backpack support Web3?+
Backpack provides a self-custodial multi-chain wallet supporting Solana, Ethereum, and Bitcoin. It includes an exchange with native DeFi integration, xNFT support for running decentralized apps inside the wallet, and cross-chain asset transfers — all secured by MPC custody technology.
What is an xNFT?+
An xNFT (executable NFT) is a Backpack innovation — an NFT that contains executable code, allowing it to run as a decentralized application directly inside the Backpack wallet. This merges NFT ownership with app functionality, creating a new paradigm for decentralized software distribution.
Which blockchains does Backpack support?+
Backpack supports three major networks: Solana (primary, with SPL tokens and xNFTs), Ethereum (EVM compatibility with ERC-20/721 and Layer 2 support), and Bitcoin (including Ordinals and BRC-20 tokens). Cross-chain transfers are native to the wallet.
