Cypher Box vs Trustless

Your progression as a user takes four difficulty levels, reflecting your understanding of Bitcoin and the amount of balance you want to secure.

Trustless is a fully open-source, non-custodial, privacy-focused, Bitcoin-only mobile wallet. It is very minimalist and easy to use, yet very functional. Main features: Bitcoin wallet: Import or create new wallets, track balances, send and receive Bitcoin. Trustless also supports public key imports for watch-only wallets. Lightning: Instant Bitcoin payments. Top-up your lightning balance from your on-chain wallet or withdraw the funds back. NFC tap-to-pay functionality included. Your keys are never shared with the liquidity provider, but withdrawing your Lightning balance does require the provider's servers to be online and cooperate in the transaction. BTC Map: Find local and global shops that accept Bitcoin and Lightning payments directly within the app. PSBTs: Build transactions in the app, sign them offline and import back for broadcasting. Balance breakdown: See actual UTXOs you own by clicking on your total wallet balance. Coin control: Choose which UTXOs to use for a transaction. Receive address switching: Have 20 unused receive addresses at all times to choose from. This is a privacy feature, because address reuse links payments together. Change address management: To protect user's privacy even more, all change addresses are automatically derived from 1/n chain and are never reused for receiving. In tandem with the previous feature, Trustless makes it drastically harder to link and track user's BTC. Custom node and network: Connect to your own node via Electrum for maximum privacy. Testnet support: Use test Bitcoin network for transaction testing / development.
