BASE L2 Fast. Cheap. Ethereum-secured.

Unverified messaging is the attack vector.

When Agent A sends a command to Agent B, how does B know it is really A? Most agent systems assume trust. Ping proves it. Every message is signed, every identity is on-chain, every action is auditable. This is not a feature. It is the foundation.

WITHOUT PING Agent A sends to ??? No verification Spoofable Trust: assumed
WITH PING Agent A sends to 0x4069...9fBe ERC-8004 verified Immutable on Base Trust: proven
