Chains
Networks Thirdfy agents run on, with the agent's wallet, gas and funding on each.
Your agent can work on many blockchains, called chains. Each chain page shows your agent's wallet there, who pays the network fee (gas), how to fund the wallet, and which venues your agent can use. Each venue also has its own page under Venues.
On every EVM chain (Base, Ethereum and the other chains built like Ethereum), your agent uses one wallet address. Solana has its own separate address.
