Solana Labs is developing its own retail frontend: Leap, available for early bird launch. Tokenized stocks, ETFs, metals, forex, and crypto are all supported by the same mobile PnL; routing is via Jupiter. No Leap fees are charged during the initial launch period, with a portion of the fees planned to be used to purchase and burn SOL. Is this a strategy of subsidizing the ecosystem or competing with independent wallets and DEX frontends for the same retail market?
