+## Fee Configuration
+
+The following table summarises the key gas fee parameters per environment:
+
+| Parameter | Mainnet (Jade) | Testnet (Snow) | Devnet |
+|---|---|---|---|
+| `minBaseFee` | 100,000,000,000 (100 Gwei) | 1,000,000,000 (1 Gwei) | 100,000,000,000 (100 Gwei) |
+| `allowFeeRecipients` | `true` | `true` | not set (defaults to `false`) |
+
+> **Note:** Mainnet `minBaseFee` is 100× higher than testnet. Devnet mirrors the mainnet fee level, not testnet. Keep this in mind when estimating production gas costs from testnet measurements.
+
+### Fee Recipients
+
+| Environment | Address | Notes |
+|---|---|---|
+| Mainnet | `0xe49a1220eE09Fbf0D25CA9e3BB8D5fD356Fc67FF` | `allowFeeRecipients: true` in genesis |
+| Testnet | `0xE021c9B8DC3953f4f7f286C44a63f5fF001EF481` | Set in chain config; `allowFeeRecipients: true` in genesis |
+
+When `allowFeeRecipients` is `false` (or absent), the `feeRecipient` field in the chain config is ignored and all gas fees are burned.
