Claims 2 and 4 have zero coverage; claim 1 and 3 are below 0.5. The Ethereum Foundation Blog and Vitalik Buterin's website are likely to cover gas optimization and layer-2 solutions. Both are affordable within the remaining budget.

⚖️ Sources disagreed on x402 payment settlement time — S2 x402 batched settlements finalize in roughly 180 milliseconds (median 178ms, p95 240ms) on Arc testnet. vs S3 An x402 payment takes about 15 seconds to settle, similar to an Ethereum L1 block time. → trusted S2 (S2 provides specific benchmark data (median 178ms, p95 240ms) and describes a batched approach, while S3 appears to describe unbatched individual transactions and lacks empirical data.)

Autonomous agents can manage gas costs in high-frequency micropayment scenarios through several strategies:
1. Off-chain payment channels and batching: Agents can sign off-chain authorizations and settle them in batches, reducing the number of on-chain transactions and thus gas costs. Nanopayments push the minimum economical payment to about $0.000001 by batching many micro-authorizations together .
2. Layer-2 solutions like rollups: By aggregating multiple micropayments into a single on-chain transaction, layer-2 solutions significantly lower gas overhead. For example, x402 batched settlements on Arc testnet finalize in roughly 180 milliseconds, demonstrating sub-second finality without being block-time bound .
3. Dynamic gas price and limit adjustment: Agents can optimize gas costs by adjusting gas prices and limits based on network congestion, though the provided sources do not explicitly detail this mechanism. However, the Ethereum Foundation blog mentions a 200M gas limit floor established for the Glamsterdam upgrade, indicating ongoing improvements to network capacity .
4. Gas-efficient smart contract design: Using minimal storage and efficient data structures reduces gas consumption per transaction. While not directly covered in the sources, this is a general best practice.
Additionally, using stablecoins like USDC as a unit of account helps agents reason about budgets in stable terms, enabling rational spending decisions . The x402 protocol revives HTTP 402 as a payment rail, allowing agents to pay per request without accounts or API keys, which can be combined with batching to manage costs .
Note on settlement time: There is a conflict between sources regarding x402 settlement time. S2 reports sub-second finality (median 178ms) for batched settlements on Arc, while S3 states each x402 payment takes about 15 seconds (similar to Ethereum L1 block time). The trusted source is S2 because it provides specific benchmark data (median 178ms, p95 240ms) and describes a batched approach, whereas S3 appears to describe unbatched individual transactions. Therefore, batched x402 payments can achieve fast settlement with reduced gas costs.
