SIENNA GROUP appears to be related to the Siena Chain project, a next-generation blockchain platform focused on speed, security, and scalability. The chain has undergone a full audit with a 6% tax rate, locked liquidity, and aggressive marketing efforts. It features buy backs, fast-tracked listings on CoinMarketCap & CoinGecko, auto liquidity, and no private sale. Dapps and staking are currently in development with a strong community presence. The project also has ties to the 'Untitled' meme token, which aims to build a secret society on Solana.
