Convert some of your funds to Solana (SOL) using a centralized exchange (Binance, Coinbase, Kucoin, Mexc, OKX etc). 

Create a Solana wallet and send the SOL to that wallet. Currently, Phantom and Solflare are leading wallet options to consider. 

Use an official buy link from this website or linktree to start swapping $SI on Raydium or Jupiter (Launching Soon after TGE)!
