# Protocol Fees

On most major chains, Fly does not charge any swap fees—users only pay the network gas fee. For long-tail assets and specific asset pairs, we apply a minimal swap fee ranging from **0.01% to 0.03%**, dynamically adjusted based on trading volume, liquidity depth, and other network-specific metrics. This structure allows us to maintain accessibility while reinforcing the protocol’s long-term viability.
