# Hanami 花見

> Smart money wallet tracking and Alpha signal analytics platform for Robinhood Chain. The name "Hanami" (花見) means cherry blossom viewing in Japanese — just as cherry blossoms bloom briefly, Alpha opportunities on-chain are fleeting. Hanami helps you catch them before they fall. Built on Robinhood Chain (Chain ID 4663, Arbitrum Nitro L2).

## Brand Story

Hanami (花見) is the Japanese tradition of watching cherry blossoms bloom at their peak. The window is achingly brief — often just a week. On-chain Alpha is no different: smart money moves first, and the window between "undiscovered" and "everyone knows" can be measured in minutes. Hanami brings the same spirit to Robinhood Chain.
