Will it work with Valora wallets?
How is it different than Valora?
The original name for this wallet was just "Celo Wallet", but to avoid confusion it has been renamed to "Othello Wallet".
This wallet was created by J M Rossy. It is not currently under active development. Only security update will be released.
It can run in a modern browser (Chrome is recommended) or on your desktop (Mac, Windows, and Linux). The desktop version has stricter security guarantees and is strongly recommended for large accounts.
Yes, the web version was designed from the ground-up to be lightweight and mobile-friendly.
Yes, you can use your Account Key (seed phrase) to import your account into Othello, back into Valora, or use both at the same time.
The most obvious difference is platform: Valora runs on iOS and Android, whereas Othello runs in browsers and on desktop. More abstractly though, Valora is a social payments application whereas the Othello is just a tool. That's why Valora includes extra features around importing contacts, verifying phone numbers, finding friends, etc. In contrast, one of this wallet's design principles is to be minimal, meaning no analytics, no plugins, and no device permissions (except for Ledger access).
Short answer: It's safe enough for small 'hot' wallets or Ledger-backed wallets. For anything larger or more important, the desktop version is strongly recommended.
Long answer: The web version does what it can to protect your funds but web apps have certain inherent limitations. Protections includes: encrypting your wallet at rest, minimal use of 3rd party code, pinning dependencies, using single-origin code sourcing, publishing bundle hashes, and other modern web development best practices. That said, the web is, by design, an open and extensible platform. That unfortunately means all web apps are vulnerable to certain risks, like malicious browser extensions. For this reason, the recommendation is to use the web version for small amounts only. For larger amounts, use the desktop version, Valora or a Ledger hardware wallet.
Your seed phrases, from which you keys are derived, are encrypted using your password and stored either in browser local storage for web or on disk for desktop. Your keys never leave your device. In other words, this wallet is a self-sovereign (non-custodial) wallet.

Yes, Ledger hardware is supported on both the web and desktop versions. Due to browser limitations, Ledger has been found to work best in Chrome.
Note though that currently not all transactions can be parsed by the Celo Ledger app. Simple payments (like CELO or cUSD transfers) will show transaction details on the Ledger itself but transfers with comments or token exchanges will not yet show details.
