PayPal has designated Solana as the default blockchain for its stablecoin PYUSD, shifting the majority of transactions to the network to leverage its speed and low fees. Meanwhile, Cardano plans to launch USDCx by the end of February to address its stablecoin liquidity gap, which currently stands below $40 million, as highlighted by Anastasia Labs CEO Philip DiSaro. Despite these significant ecosystem developments, the price reactions for SOL and ADA have been muted, suggesting the market may have already priced in the news or is awaiting actual usage data.
