According to CoinMeta, investors are identifying dominant artificial intelligence models and applications and are investing substantial funds in them. If artificial intelligence becomes as important as market expectations, then what kind of financial infrastructure will its economy rely on? There are increasingly many signs that blockchain and digital assets will play a key role. AI Agents will not only generate text or analyze data but also negotiate with other agents, purchase computing resources, pay for data fees, and execute transactions. Traditional payment infrastructure is not suitable for millions of autonomous software agents to conduct low-value transactions, whereas blockchain infrastructure can support the programmability of funds. AI Agents can interact with wallets, execute smart contracts, or transfer stablecoins, reducing the need for manual intervention. Stablecoins are particularly important in this process as they connect the programmability of blockchain with familiar units of measurement. Investors should pay attention not only to the companies that build these models but also to the infrastructure that supports machine-to-machine economic activities.
