Add wallets and x402 #30
Description
We want the agent to have wallets. When it starts up, it should generate a wallet for itself. The admin can export the private key, swap the private key, and we want them to be able to refill the wallet with money. We have an EVM and solana wallet and we want to support both. We also have some x402 code and a new agentkit plugin and we'd like to support an x402 payment abstraction in our agent as well as in the API layer-- so our agent can pay for the Eliza API directly as needed. Our goal is that the Eliza inference services and accounts can be set up, administered and connected entirely without a user.
In the game, we want the agent to be aware of how much money it has and what it can buy and pay for. This should unlock once it has found and read the letter from the creators.
