Any P2P network with on-chain payments faces the same tradeoff: either run a hot wallet with real funds so your node can transact autonomously, or introduce custodial key management and hope the operator doesn't disappear. Both options have well-understood failure modes. Hot wallets get drained. Custodians get hacked, or worse, rug.

AntSeed sidesteps this entirely. The key that runs on your node never touches real funds. The wallet that holds your money never touches the node. They are cryptographically unrelated. Compromising one does not compromise the other.

HTTP 402 Payment Required has been in the HTTP spec since 1997 — "reserved for future use." For nearly three decades, no one agreed on what the payment payload should look like, how the negotiation should work, or who should facilitate it. That changed recently. Coinbase shipped x402, Stripe and Tempo launched the Machine Payments Protocol (MPP), and several smaller projects have proposed their own 402 conventions.

All of these give 402 a mechanism. They differ in architecture — specifically, in who sits between buyer and seller, and whether that intermediary is required.

AntSeed uses 402 as the trigger for fully decentralized payment negotiation between peers. No payment gateway, no relay, no facilitator. The entire flow — from the initial 402 response to the on-chain reserve to the retried request — happens over the same peer connection that carries the actual AI traffic.
