Every tunable parameter that affects fees, throughput, user experience, or economic security. Parameters grouped by business impact and compared against peer Cosmos-EVM chains (Evmos, Kava, Cronos, Canto, Sei).
| Attribute | Value |
|---|---|
| Lumera default | 0.0025 ulume/gas (~2.5 gwei equivalent) |
| Where set | config/evm.go FeeMarketDefaultBaseFee |
| Governance changeable | Yes |
Peer comparison: Evmos 1 gwei, Kava 1 gwei, Cronos 5000 basecro/gas, Canto 1 gwei.
Recommendation: Review once token price is known. Current value likely fine for launch.
Lumera: 0.0005 ulume/gas (20% of base_fee). Never set to 0 - Canto showed zero-floor chains get spammed.
Lumera: 16 (~6.25%/block) vs upstream 8 (~12.5%). Fees adjust twice as slowly. Pro: predictable fees. Con: slower spam pricing during spikes.
Recommendation: Consider 8 if expecting volatile demand. Keep 16 if fee stability is priority.
| Chain | Block Gas Limit | Block Time | Effective Gas/sec |
|---|---|---|---|
| Lumera | 25,000,000 | ~5s | ~5M gas/s |
| Ethereum | 30,000,000 | 12s | ~2.5M gas/s |
| Evmos | 40,000,000 | ~2s | ~20M gas/s |
| Sei | 100,000,000 | 0.4s | ~250M gas/s |
Recommendation: 25M appropriate for launch. Raise to 40M if avg utilization > 50%.
