ERC-8004 Agents on Avalanche C-Chain

Avalanche’s C-Chain finalizes blocks in under a second and runs EVM bytecode without changes. The subnet architecture is the interesting part: agent fleets can spin up a dedicated validator set for their own domain, rather than sharing the public network. This isolation also means the subnet can enforce its own rules around who can register agents or submit feedback, which matters for enterprise deployments with compliance requirements. For ERC-8004, the C-Chain is a good default; subnets are worth looking at if you need tighter control.
