Solana's stablecoin supply is approaching $13 billion, with the network handling nearly 50% of all USDC transfers. The network currently hosts $12.8 billion in stablecoins, bolstered by a recent minting of 250,000 USDC by Circle. Nicky Scannella from Marinade Labs attributes Solana's appeal to its liquidity, security, and efficiency. Regulatory clarity and growing institutional interest are key factors driving the influx of stablecoins to Solana. Additionally, Marinade's integration with Paxos' USDG stablecoin is supporting the network's decentralized expansion, further enhancing its position in the stablecoin market.
