The June 10, 2026 release lets users add coin flips or dice rolls before a seed phrase is generated, reducing reliance on a phone's built-in random number generator.
BlueWallet's 8.0.0 release, published June 10, 2026, adds a manual entropy feature that allows Bitcoin users to supply their own randomness during wallet setup by entering coin flips or rolls from 6-sided or 20-sided dice. The option appears in Advanced mode and targets 256 bits of entropy, the standard level used for a secure Bitcoin seed phrase (wallet recovery words). If the manual input does not reach that threshold, the app completes the remaining randomness with the device's system RNG (random number generator). The feature addresses a long-running debate among some Bitcoin users over whether software RNGs are sufficiently trustworthy, since physical inputs such as dice rolls and coin flips can be directly observed and verified. BlueWallet has also emphasized the option in its offline cold-wallet (storage kept off the internet) creation guide, signaling that it is aimed more at security-focused, long-term storage than everyday spending. As an open-source Bitcoin wallet available on iOS and Android, BlueWallet's move brings a capability long associated with hardware wallets such as Coldcard into software, narrowing one of the traditional arguments for hardware-only cold storage.
