1. Solana Network Fees:
The Solana network is known for its very low fees. Typically, the fee for each transaction (including a swap) is less than 0.001 SOL (roughly a few cents). However, a swap might involve multiple transactions (e.g., approval and token transfer), so you should account for slightly more.
2. Phantom Swap Fee:
The Phantom wallet itself charges a fixed fee of 0.85% of the transaction amount for swaps. This fee depends on the value of the token being swapped, not a fixed SOL amount. For example, if you swap $100 worth of tokens, Phantom’s fee would be about $0.85, which needs to be paid in SOL.
