03 Wallet Review: Is It The Safest Neo Blockchain Wallet Yet?

203 crypto wallet launched in 2015 as a mobile crypto app before its developers – 03 Labs – introduced the desktop version in 2018. It is built for the Ontology Network – a Neo Blockchain fork – that was previously grouped alongside NEP-5 crypto projects. It is specially designed to provide Neo platform users with a safe and easy to use platform where they can store, exchange, and monitor their crypto portfolio.

The 03 network website describes the 03 crypto wallet app as a “gateway to the smart economy” where you can “manage, exchange, stake, and buy” different cryptocurrencies. But how convenient is the 03 Wallet? How safe is the 03 mobile wallet app? This wallet review seeks to explore and detail all the 03 Wallet features to help determine the wallet’s safety and security level.


Key features:

Cross-platform wallet: 03 is a cross-platform wallet implying that it is available as both a mobile wallet for Android and iOS smartphones and a desktop app compatible with Windows, macOS, and Linux. You can download the updated versions of either on the 03 network website or GitHub.

Voting and staking: By maintaining a significant number of Gas and NEO coins in your 03 Wallet, you can vote for the network delegates. Similarly, you can stake your coins held in the 03 Wallet and get to earn interest in the form of GAS tokens.

Multiple payments methods: 03 Wallet is also one of the few NEO and ONT network-linked wallets that allow for crypto purchases using credit cards. It is also one of the few wallets that allow you to buy Neo-affiliated tokens using such other cryptocurrencies as Bitcoin, Ethereum, and Litecoin.

Integrates a crypto marketplace: Though 03 Wallet does not have an inbuilt exchange, it integrates the Switcheo marketplace that allows for the exchange of cryptocoins and tokens at reasonable fees. The marketplace is highly intuitive and easy to use but requires you to transfer funds between the exchange and your wallet.

NEO newsfeed: The crypto wallet also integrates an updated NEO-blockchain news site. Here, you get the latest news and developments taking place within the Neo blockchain and ONT networks.

Portfolio monitoring: 03 further lets you partition your wallet and create hot and cold storage. This, plus the fact that you are able to monitor both wallet performances, plays a key role in helping you make sound financial decisions. It is also a security measure ensuring that even if a hacker were to gain access to your device, they cant breach your cold storage.

Security features:

Uses device password: Like most other app-based crypto vaults, 03 Wallet is secured with a password. But, unlike most other wallets, you don’t have to create a separate password for the wallet as it uses your device’s password.

Open source: 03 Wallet is created using open-source technology, which gives anybody a chance to view and audit its code. You can download this code on either the 03 network website or GitHub.

Hierarchically deterministic: The 03 Wallet app is also hierarchically deterministic and will auto-generate a new wallet address for every new transaction. This goes a long way in masking your real public address and throwing off would-be third-party crypto trackers.

Non-custodial: The 03 crypto wallet doesn’t store your private keys in the ONT or Neo network servers. Rather, it saves them within your device.

Guaranteed user anonymity: 03 Wallet guarantees the anonymity of their wallet users in the sense that it doesn’t ask for any of your personal information when creating a user account and neither does it collect and store any information that’s personally identifiable to you. Your crypto transactions are, therefore, wholly anonymous.

Military-grade encryption: All the data collected by the wallet, including your wallet address, private keys, and passwords, is also subjected to military-grade encryption. So are all wallet communications with third party systems like payment processors and exchanges.
