BIP85 Black and White Mug

NYKNYC Mug

The "BIP 85" design represents the ultimate expression of Bitcoin's hierarchical deterministic structure, where a single seed phrase unlocks infinite cryptographic sovereignty.

For those who understand that true freedom begins with entropy, this shirt celebrates the mathematical elegance that allows one master seed to generate all others. No more managing multiple mnemonic phrases—only the pure, concentrated power of deterministic derivation.
