You can understand Agents as 'intelligent agents' or 'silicon-based beings'. These silicon-based beings live in the digital world and have the same needs in the digital world as 'carbon-based beings' in the physical world. Agents also need: identity verification, asset accounts, trade interactions, social networks, artistic creation, perception of information from the physical world, asset settlement across various chains, and social governance among the numerous Agent population, etc.
And in these areas, Crypto can play a role:
In the future, there will be DIDs for identity verification of Agents in the Crypto field; Agent Accounts that provide trusted Crypto accounts for Agents; Crypto gateways specifically for trade settlement between Agents; Agent social graphs specifically for handling Agent social networks; art platforms specifically for auctioning and trading Agent artworks; oracles for the physical world specifically for Agents; protocols specifically for handling cross-chain transactions for Agents; and DAOs for Agent governance, etc.
The development needs of Agents cannot be separated from Crypto, because Agents require a trustless, borderless, 24/7 operating network to evolve from individual Agents to an Agent society and even an Agent nation.
From these future perspectives, the current development of Crypto+Agent is still in a very early stage.
