Binance appears to be using Solana for transfers to market makers (firms that support trading liquidity) and other exchanges, based on activity visible through Solana's public block explorer. The flows are not retail deposits or withdrawals, but institutional trading infrastructure that helps move liquidity between venues. Tron and Ethereum previously handled these transfers, with Tron favored for low-cost USDT movement and Ethereum generally used for larger, higher-value transactions. Solana offers transaction costs of less than one cent and sub-second finality, meaning transactions become irreversible quickly, although Binance has not said whether cost or speed prompted the apparent change. The exchange has not disclosed which assets are involved, how much volume has shifted, or whether the move is permanent, partial or a reversible test. Analysts and market participants will be watching Binance's public comments, Solana transfer volumes linked to the exchange, and activity in Binance-linked Tron and Ethereum wallets.
