The predecessor of YAKUZA DFO was YFKZ. After the initiator drained the liquidity pool and disappeared with the funds, those left in the community, together with crypto enthusiasts, rebuilt the YAKUZA DFO community. YAKUZA DFO migrated the old token YFKZ to the enhanced YKZ token, compensating each YFKZ holder on a value-for-value 1:1 basis by swapping their old tokens for the new, improved, and more versatile YKZ tokens.
