what's Petra Wallet?

Petra Wallet is a self-custodial cryptocurrency wallet designed specifically for the Aptos blockchain, developed by Aptos Labs. It enables users to securely store and manage APT coins, other tokens, and NFTs, while providing seamless interaction with decentralized applications (dApps) on the Aptos network. Key features include sub-second transaction speeds, extremely low fees (under $0.001), full user control over private keys, and privacy-focused operations, with independent security audits ensuring safety. The wallet is available as a browser extension (e.g., Chrome) and web app, supporting activities like token transfers, NFT collection, stablecoin yields, and Web3 exploration. It emphasizes intuitive usability for both newcomers and experienced users, positioning it as a primary gateway to the Aptos ecosystem's high-performance Move-based smart contracts and parallel execution capabilities.

Recent tweet dismisses Petra as a memecoin, comparing it to TNSR and promoting MetaDAO.
