Jup Mobile implements a zero-fee model for on-chain transactions, and this advantage is quite obvious. Mainstream wallets on the market usually charge a fee of 0.25-1.5% per transaction, and what's more troublesome is that these costs are often hidden within the exchange rate, so users may not be able to see them clearly. You need to compare carefully to find out how much you've been charged. If calculated based on lifecycle transaction volume, this small fee difference can add up to a significant expense. For frequent traders, a zero-fee solution like Jup Mobile can save a lot of costs in the long run.
