Wallets
You need a wallet to hold ecash from any of these mints. Most wallets talk to several mints at once, so you are not tied to the first one you try.
Mobile ecash wallet with its own mint, Lightning address support and Nostr contacts.
Browser wallet that handles multiple mints at once and imports and exports raw tokens.
Mobile wallet focused on multimint balances and sending ecash over Nostr.
Reference web wallet from the Cashu project. Runs entirely in the browser, installable as a PWA.
Web wallet built around Lightning addresses and sending ecash by link.
Lightning wallet and point of sale that also runs its own Cashu mint.
Nostr messenger with an ecash wallet built in, for sending sats inside chats.
The reference implementation. Runs as a wallet on the command line and as mint software.
This list is not exhaustive and is not an endorsement. The Cashu project keeps a broader index at docs.cashu.space/wallets. A wallet holds keys, a mint holds the money: read the mint reviews before you pick where your sats live.
