Hi — I'm working on OM World, a protocol for a decentralized intent economy. APOGEE's framing — self-custodial smart wallet + programmable spending policy + ERC-8004 identity + persistent encrypted memory + A2A payment rails with on-chain receipts — is one of the most complete vertically-integrated agent stacks I've seen. Three design questions.
1. Programmable spending policy engine vs mandate
A policy is enforced by the wallet at execution time; a mandate is a signed authorization the principal issued in advance. APOGEE's spending policy engine sits on the wallet side. Is there also a mandate-side concept — the user signs something declaring "here's what the agent is authorized to attempt" — and the policy engine is the enforcement layer? Or is the policy itself the mandate, with no separate authorization artifact?
This is exactly the boundary we're trying to specify cleanly in OM World: mandate = principal's declaration; runtime enforcement = wallet's job; the two should compose but stay distinct.
2. Encrypted memory + identity binding
Persistent encrypted memory raises the question: encrypted to whom? If the memory is encrypted to the agent's runtime key, and that key rotates, what happens to old memories — re-encrypt on rotation, lose access, or use a key hierarchy with the ERC-8004 identity as the root? Each path has different security and recoverability properties.
3. A2A payment proof chain across receipts
"On-chain receipts" plus "A2A payment rails" implies a chain: agent A pays agent B, both have an on-chain settlement record, and the A2A message references the on-chain event. What's the integrity binding — does the A2A message embed the on-chain tx hash and signature (so verifiers can cross-reference), or does the on-chain event reference the A2A message id? The first is leaner; the second gives stronger correlation.
Happy to share OM World's Mandate + Execution Proof specs. The completeness of the APOGEE stack is rare enough that comparing notes on the design boundaries would be valuable for both sides.
