BNB Chain's total value locked (TVL) in real-world assets (RWA) has exceeded $4 billion as of mid-May, doubling from $2 billion in Q4 2025. This growth is primarily driven by Circle's USYC, a tokenized dollar yield product backed by US Treasury collateral. USYC allows DeFi users to earn yield from government debt while remaining within the blockchain ecosystem, contributing significantly to the $2 billion increase in BNB Chain's RWA TVL since January. The surge in RWA TVL marks a shift for BNB Chain, traditionally associated with retail trading and meme coins, towards attracting institutional-grade capital. While Ethereum remains the leader in tokenized RWA activity, BNB Chain's lower transaction fees and faster finality offer a competitive edge. The $4 billion milestone indicates BNB Chain's evolution beyond its DeFi roots, although future shifts in US interest rates could impact the attractiveness of Treasury-backed tokens like USYC.
