The Lightning Network provides trustless scaling for Bitcoin and offers instant finality for payments.
Ark likewise offers trustless scaling, but Ark payments only reach finality after at least one block confirmation, the same as on-chain Bitcoin.

In the next version of Keychat, using Mini Apps will be more immersive with the top bar removed.
A virtual Home button will be added in the bottom-right or bottom-left corner, similar to the physical Home button on older phones.
Long-pressing it will return to the Browser home screen, while a short press will bring up the option menu.
@ManyKeys Thank you for your feedback and suggestions.

NOSTR_1 Does the Arkade wallet use the Nostr nsec format for its private key?

View quoted note →The counterparty risk of holding Cashu-mint–issued ecash sats is proportional to the holding time. The longer you hold ecash sats issued by a Cashu mint, the greater your counterparty risk.
When a user wants to send 10,000 Cashu ecash sats to a friend for better privacy and convenience (without needing the recipient’s address), Keychat Wallet can combine the minting and sending of Cashu sats into a single operation instead of maintaining a continuous 10,000-ecash-sat balance. This reduces the time the user holds the ecash sats.
Thus, the Cashu mint is better used as a privacy-preserving bridge rather than for secure long-term storage.

Imagine Keychat Wallet supporting both an Ark wallet and a Cashu wallet.
Most funds would be kept in the Ark wallet, while the Cashu wallet balance would be automatically kept at 1,000 sats.
If the Cashu balance drops below 1,000 sats, Ark sats would be automatically converted into Cashu sats; if it rises above 1,000 sats, Cashu sats would be automatically converted back into Ark sats.
That way, a user’s maximum loss from a Cashu mint failure would be limited to 1,000 sats.

Postal systems use stamps to deter spam and raise revenue.
Ecash sat is the best digital stamp because it’s a anonymous bearer token — essentially a piece of data.
Like a physical stamp that sticks to an envelope, a digital stamp can be attached to a message.
A message relay can function as a digital post office, deterring spam and generating revenue by requiring digital stamps.
