Shiba Inu is a meme coin built on Ethereum, named after the same Japanese dog breed that fronts Dogecoin. It launched in August 2020, created by an anonymous person or group using the pseudonym Ryoshi, and was pitched from the start as a Dogecoin competitor. The token uses the ticker SHIB.
SHIB is not its own blockchain. It is an ERC-20 token, meaning it lives on the Ethereum network and follows Ethereum's shared token standard. Because of that, it inherits Ethereum's rules and its proof-of-stake consensus rather than running a chain of its own. Sending SHIB is an Ethereum transaction, and it sits in the same kind of wallet you would use for ether and other Ethereum tokens.
What started as a single joke token grew into a wider project with several pieces. It centers on three tokens: SHIB, plus two others called BONE and LEASH, each with a different role inside the project. The team also built ShibaSwap, a decentralized exchange where holders can trade and pool these tokens without a central operator taking custody. Later came Shibarium, a layer-2 network that processes transactions off to the side of Ethereum to make them cheaper and faster, then settles back to the main chain. Together these turned Shiba Inu from a standalone coin into a small cluster of connected apps and tokens.
For most of its life, the practical pull of Shiba Inu has been community and culture rather than a specific technical job it does better than rivals. It rode the same wave of dog-themed coins that made Dogecoin a household name, and a large, vocal online following has been central to its story. That following rallies around the project's tokens and apps and treats the brand itself as much of the draw.
A meme coin is worth understanding for what it is. Its design does not promise a fixed supply schedule, a yield, or a built-in use that anchors demand. Value rests heavily on attention and sentiment, which can shift fast in either direction. Shiba Inu has, at times, drawn the kind of mainstream notice that few tokens of its type reach, but that notice is a measure of popularity, not of any guaranteed staying power. Anyone weighing it should separate the cultural reach of the brand from the harder question of what the token does and why it would hold value over time.
