# MathWallet

> The Multichain Wallet for Web3

MathWallet is a multi-platform cryptocurrency wallet supporting multiple blockchains and thousands of digital assets. It lets users store, manage, and trade tokens across mobile, browser, web, and hardware interfaces.

MathWallet is a multi-platform cryptocurrency wallet, a self-custody wallet provider serving users who hold and manage digital assets across multiple blockchains. It is available as mobile applications, browser extensions, web interfaces, and hardware wallet integrations, giving users access to decentralized applications, token swaps, and staking services. The wallet is built for users who want control over their private keys, while also offering a cloud wallet option for simplified onboarding.

The platform addresses the need for a single interface to interact with many separate blockchain ecosystems rather than juggling multiple chain-specific wallets. It provides a built-in decentralized application store, cross-chain bridging tools, and a non-custodial signing model where users retain control of their keys. An associated blockchain network built on a modular framework extends the ecosystem with smart contract and identity features.

Beyond the core wallet, the broader offering includes an NFT wallet, staking tools, and a bridge for moving tokens between networks, grouped around the MathWallet application. It is used by individual holders, decentralized application developers integrating wallet connectivity, and traders moving assets across multiple networks.
