Kiba Inu v1 (KIBAV1) is the original version of the Kiba Inu cryptocurrency, launched in October 2021. Initially positioned as a memecoin, KIBAV1 introduced unique smart contract features aimed at encouraging long-term holding and reducing speculative trading. The token was deployed on both the Ethereum (ETH) and Binance Smart Chain (BSC) networks, supporting cross-chain compatibility.

A defining aspect of KIBAV1's smart contract was its early sell-tax mechanism, which applied a higher tax rate to users who sold their tokens within 24 hours of purchase. This approach was designed to limit short-term trading and stabilise the token's market value. However, as the market evolved, this mechanism was phased out in favour of a simpler model featuring a flat 6% sell tax and no buy tax.

Kiba Inu v1 (KIBAV1) primarily functioned as a memecoin with a focus on speculative trading. Its unique sell-tax mechanism encouraged users to hold their tokens for at least 24 hours, limiting price volatility caused by short-term trading. The design of the KIBAV1 smart contract prioritised community engagement and long-term growth, which later influenced the evolution of its successor, Kiba Inu (KIBA).

Beyond its memecoin status, KIBAV1 introduced utility features like liquidity pool enhancements and early incentives to promote token stability. While the project's core use case was initially centred around trading and speculation, its development team laid the groundwork for more utility-driven features in later versions, including the development of Kibaswap—a decentralised exchange (DEX) that became a key part of the broader Kiba Inu ecosystem.
