You'll need an SPL wallet to connect to Raydium. First of all, hardware/cold wallets are the most secure wallets. So the best wallets to use with Raydium will be Trezor Model T and Ledger Nano X. However, software wallets like Sollet.io, Ledger, Solong, Phantom, Math, Blocto, Solflare, and Bonfida wallets are also supported by Raydium. Raydium (RAY) will continue to add more wallets as they become available.
