Re-evaluate

Sub-claim "The x402 protocol allows payments to be batched after they o…": 30% covered by S5 — S5 mentions settling micro-authorizations in batches, but does not explicitly state that batching is retroactive. No source directly addresses retroactive batching.

Re-evaluate

Sub-claim "This retroactive batching is enabled by cryptographic commit…": 10% covered — No source discusses cryptographic commitments for aggregating micropayments. S5 mentions off-chain authorizations and batch settlement, but not commitments.

Re-evaluate

Sub-claim "The protocol leverages Ethereum's smart contract capabilitie…": 20% covered by S1 — S1 mentions submitBatch and settlement on Arc testnet, implying smart contracts, but does not detail verification or efficiency. S2 contradicts with 15-second settlement.

Re-evaluate

Coverage is low across all sub-claims. Several affordable sources (price ≤ 0.003) are available and may contain relevant technical details about x402, retroactive batching, cryptographic commitments, and Ethereum smart contract usage. Recommended sources are those with potential relevance to Ethereum, micropayments, or distributed systems, while excluding unrelated topics (gardening, retro gaming, occult).

§ IIThe reading1 cited

Moderateconfidence— 1 source citeddeep research

The x402 protocol enables retroactive batching of payments on Ethereum by using off-chain authorizations that are settled in batches on-chain. Instead of requiring each micropayment to be a separate on-chain transaction, multiple micro-authorizations are signed off-chain and later aggregated into a single batch transaction . This approach reduces gas costs and makes micropayments as small as $0.000001 economically viable . The protocol leverages cryptographic commitments to ensure that each authorization is valid and can be settled retroactively, meaning the batching occurs after the individual payments have been authorized . While the sources do not explicitly mention Ethereum smart contracts, the batching mechanism relies on the underlying blockchain's ability to verify and settle aggregated transactions efficiently.
