Offline Cash is a manufacturer of the Bitcoin Note, a physical self-custodial Bitcoin bearer instrument that combines currency-grade printing, secure NFC hardware and a time-locked multisignature Bitcoin script. Offline Cash's Twitter Score is 9.8 out of 1000 as of October 2026, ranking #95,806 among 493,668 tracked accounts.
Offline Cash produces the Bitcoin Note as a non-custodial instrument built on a multisignature script requiring both a user key and a manufacturer key until a set claim date, after which only the user key is needed. Notes are not pre-loaded with bitcoin; the first holder supplies entropy to generate the user key and funds the associated Bitcoin address directly. To claim funds before the claim date, the holder cuts a circuit trace, prompting Arx Research-affiliated servers to release a decryption key for the manufacturer key. The client application is open source, enabling independent fund claiming once the printed claim date has passed.
Offline Cash offers the Bitcoin Note in denominations of 1, 2, 5 and 10 mBTC. Offline Cash has published 421 posts on the platform and has been mentioned by 14 accounts a total of 18 times.
