If we look at avg transaction fees over the whole year of 2025 (see table below), the numbers are quite different for Solana vs Arbitrum One. A couple of important points here also: 1. Arbitrum DAO intentionally set the min base fee to 0.02 gwei to prevent spam transactions from growing state for full nodes incl RPCs. This is a very easy number to lower if we didn’t care about HW requirements, and Arbitrum Stack L2s are free to make this tradeoff. 2. Dynamic pricing in ArbOS 60 Elara (next upgrade) will further drop avg transaction fees without increasing hardware requirements blog.arbitrum.io/dynamic-prici...… 3. Solana inflates token at current rates around $5 billion per year to subsidize decentralization / transaction fees blockworks.com/analytics/chain...…. Arbitrum token doesn’t require any inflation to subsidize fees. Arbitrum chains consistently operate at a 90-98% profit margin galaxy.com/insights/research/e...…. These transaction fees go to the DAO to invest back into the ecosystem. 4. Offchain Labs is also actively working on a new transaction type that will have substantially lower fees (again, without increasing hw reqs), stay tuned 😉
