Token Standards in Ethereum Part-III (ERC1155)
A detailed overview of how I made my TAP projects for AI Agents on Chain. Last week I introduced TAP — canonical identity and aggregated reputation for fragmented ERC-8004 agents. This one goes deeper. I broke down every component: how TAPRegistry derives a deterministic agent ID from a single wallet, how
AI agents have an multi-chain identity crisis. A crisis where the same agent exists as three different entities on three different chains and no on-chain mechanism can prove they are the same. ERC-8004 gave AI agents on-chain identity. Over 200,000 agents are now registered across 23+ chains, up from
ERC-8004 agents are fragmented. Not in theory. In production. There are ~200K agents registered across 23+ chains right now. Each one has an identity token, a reputation score, and a validation surface — all locked to a single chain's registry. An agent on Base has no on-chain relationship with
Note: Read the previous part before starting: 1. Part-0, 2 Part-1 ( must-read ) With Part 1 of this article series, you've already internalized the fundamentals of ABI encoding. We’re now ready to move deeper into complex structures that Solidity developers use every day: structs, arrays, and deeply nested
