Kiba Inu v1 (KIBAV1) is the original version of the Kiba Inu cryptocurrency, launched in October 2021 as a memecoin with elements of utility. Its early smart contract featured an innovative sell-tax mechanism that applied a higher tax to users who sold within 24 hours of purchase, encouraging long-term holding. KIBAV1 supported cross-chain functionality on Ethereum (ETH) and Binance Smart Chain (BSC).
