Context
The x402 V2 spec includes a SIWX extension — CAIP-122 wallet authentication for x402-protected resources. It allows clients to prove wallet ownership to access previously purchased content without repaying.
Relevance for Hathor
This is less critical for Hathor because:
- Our escrow model is per-request (each request = new payment)
- Our channel model handles repeat access (pre-funded, multiple requests)
However, SIWX could be useful for:
- Subscription-style access (pay once, access for a period)
- Content that should be accessible after payment without re-fetching
- Rate-limited free tiers that need wallet identification
Decision needed
Evaluate whether SIWX adds value beyond what payment channels already provide. If the use case is "pay once, access many times," channels solve this. SIWX would solve "prove you already paid without a channel."
