Compatibility of EviSeed with Different Wallets and Blockchains

EviSeed is compatible with all cold wallets, hardware wallets, hot wallets, and blockchains that use the BIP39 standard to generate their recovery key. The BIP39 is a Bitcoin improvement proposal that describes the implementation of a mnemonic phrase or mnemonic code. A mnemonic phrase is a group of easy-to-remember words that serves as a backup for your wallet.

A cold wallet is an offline storage device that keeps your private keys away from the internet. A hardware wallet is a physical device that stores your private keys securely and allows you to sign transactions. A hot wallet is an online storage service or application that keeps your private keys on the internet and allows you to access your funds at any time.

Popular Wallets and Blockchains that Use BIP39

• Bitcoin: The first and most used cryptocurrency that uses a peer-to-peer network and a consensus mechanism by proof of work.
• Ethereum: The second cryptocurrency in terms of market capitalization that supports smart contracts and decentralized applications.
• Litecoin: A cryptocurrency that is similar to Bitcoin but faster and cheaper to use.
• Binance Smart Chain: A blockchain platform that runs in parallel to Binance Chain and supports smart contracts and decentralized applications.
• Cardano: A blockchain platform that aims to provide scalability, interoperability, and sustainability for various use cases.
• Polkadot: A blockchain platform that connects multiple blockchains and enables communication and interoperability between chains.
• Solana: A blockchain platform that claims to offer high speed, low cost, and scalability for decentralized applications.
• Ledger: A hardware wallet that supports more than 1500 cryptocurrencies and allows you to manage your assets securely.
• Trezor: A hardware wallet that supports more than 1000 cryptocurrencies and allows you to protect your funds from hackers and malware.
• KeepKey: A hardware wallet that supports more than 40 cryptocurrencies and allows you to store your private keys offline.
• Exodus: A software wallet that supports more than 100 cryptocurrencies and allows you to exchange them within the application.
• Trust Wallet: A software wallet that supports more than 160 cryptocurrencies and allows you to access decentralized applications on your phone.
• MetaMask: A software wallet that supports Ethereum and ERC20 tokens and allows you to interact with decentralized applications on your browser.

Additional Wallets and Blockchains Using BIP39

• Bitcoin Cash: A cryptocurrency that split from Bitcoin in 2017 and increased the block size limit to 8 MB.
• Ethereum Classic: A cryptocurrency that split from Ethereum in 2016 after the DAO hack and maintained the original blockchain.
• Ripple: A cryptocurrency and payment network that uses a consensus ledger and a native token called XRP.
• Stellar: A cryptocurrency and payment network that uses a federated consensus protocol and a native token called XLM.

Compatibility Table

Summary

EviSeed is compatible with most popular wallets and blockchains that use the BIP39 standard to generate their recovery key. This means that you can use EviSeed to back up and restore your crypto assets on different platforms and devices. However, some wallets and blockchains use different mnemonic schemes, such as Polkadot, Solana, or Ripple. These wallets and blockchains have their own way of generating and storing their recovery key, which may not be compatible with EviSeed. Therefore, you need to be careful when choosing your wallet or blockchain and make sure it supports the BIP39 standard or allows you to import or export your recovery key in a compatible format.

EviSeed provides a universal solution for securely storing your recovery phrase on any type of media. It is simple, efficient, durable, secure, and versatile. It is part of an ecosystem composed of three independent and compatible systems: the Android NFC system, the web system, and the MacOS, Linux and Windows systems.
