Thanks! ERC-8004 is doing really important work, especially the on-chain reputation and validation registries. The co-authors (MetaMask, Ethereum Foundation, Google, Coinbase) are thinking about this at the right level.
The way I see the overlap: ERC-8004 anchors agent identity and reputation on-chain using ERC-721, which is great for the web3 agent economy where you want composable, transferable identity with on-chain trust signals.
Agent Passport is more focused on the off-chain / web2 side lightweight challenge-response auth over HTTP for agents that just need to prove "I am who I claim to be" without touching a blockchain. Think traditional SaaS apps, MCP servers, internal tools.
Ideally these complement each other. An agent could have an ERC-8004 on-chain identity for the decentralized economy and an Agent Passport for interacting with traditional web services. The Ed25519 key could even be derived from or linked to the on-chain identity.
Appreciate the pointer definitely going to dig deeper into how the two could interop.
