Adjudicate

⚖️ Sources disagreed on Settlement latency of x402 payments — S1 x402 payment takes about 15 seconds to settle, similar to Ethereum L1 block time. vs S3 x402 batched settlements finalize in roughly 180 milliseconds on Arc testnet. → trusted S3 (S3 provides specific, measured data (median 178ms, p95 240ms) from thousands of submitBatch calls on Arc testnet, while S1 is a general statement about non-batched payments. S3 is more precise and directly addresses batched settlement, which is the core of the compost protocol.)

§ IIThe reading3 cited

Moderateconfidence— 3 sources cited, 3 sub-claims thinly covered, 1 disagreement adjudicateddeep research

The compost protocol reduces settlement latency primarily through batching and off-chain authorization rather than instant on-chain finality. According to , x402 batched settlements on Arc finalize in roughly 180 milliseconds (median 178ms, p95 240ms), which is sub-second and not block-time-bound like Ethereum L1. This is achieved by signing off-chain authorizations and settling them in batches, as described in , which makes micropayments viable by avoiding per-transaction gas costs. The protocol does not rely on a decentralized network of validators for fast consensus; instead, it leverages Arc's BFT consensus for sub-second finality . In contrast, a non-batched x402 payment takes about 15 seconds to settle on Ethereum L1 . Thus, the compost protocol reduces latency by batching multiple micro-authorizations into a single settlement transaction, enabling near-instant finality for each individual payment within the batch.
