AVAX, DOT, and APT are the preferred stablecoin public chains for Wall Street-listed companies. Avalanche (AVAX), with its sub-second confirmation, ultra-low gas, and institutional-grade security, deeply integrates with TradeFi and RWA, serving as the core carrier chain for USDe/USDC. It has received significant investment from Visa and BlackRock, leading in scale and recognition. Polkadot (DOT) dominates asset circulation through cross-chain interoperability. APT supports high-frequency, compliant scenarios with its high performance. Opera's significant investment in Celo further confirms that stablecoin public chains are becoming a strategic standard for listed companies, and the Wall Street landscape is clear. Nasdaq giant Opera is openly manipulating Celo, planning to replace USD cash rewards with 160 million $CELO tokens, with a community vote imminent. This browser giant, with 14 million MiniPay users, is using a token conversion model that locks its own revenue with the Celo ecosystem, signaling strong control.
