ERC-8162: THE SUBSCRIPTION LAYER FOR THE AGENTIC ECONOMY

Summary from the TLDR Crypto newsletter

ERC-8162 proposes a subscription protocol for onchain AI agents complementing x402's per-request model, enabling tiered cycle-based access plans where a single onchain transaction grants zero-marginal-cost access for the subscription period. The protocol enforces direct settlement and uses EIP-712 signature recovery for self-contained, trustless access verification over the same HTTP 402 surface as x402. A notable architectural property is its elimination of combinatorial billing in multi-agent call chains: where per-request costs compound multiplicatively across deep agent-to-agent compositions, subscriptions reduce inter-agent call costs to zero after the initial commitment.
