Fix per-tx gasUsed to report actual gas consumed, not gas limit#158
Conversation
The block API was storing tx.gas (the gas limit from the transaction envelope) as gasUsed for each transaction. The correct value was already available in MeterBundleResult.gasUsed from the bundle history in S3. Now includes both fields per transaction: - gasLimit: from the transaction envelope (always available) - gasUsed: actual gas consumed from meter data (null when unavailable) The UI shows "gasUsed / gasLimit gas" when meter data exists, or "gasLimit gas limit" for transactions without it (e.g. L1 deposit tx). Cache deserialization is backwards-compatible with existing cached blocks that only have the old gasUsed field (interpreted as gasLimit).
