How Fees Work

EVM transactions use the standard gas fields expected by Ethereum tooling: 
Maximum Fee = Gas Limit x Max Fee Per Gas
Users specify:
  • maxFeePerGas: Maximum total gas price willing to pay
  • maxPriorityFeePerGas: Maximum priority tip
  • gasLimit: Upper bound on gas consumption

​
Key Differences from Ethereum

c8ntinuum uses EIP-1559-style fee-market parameters. EIP-1559 defines a protocol base fee that adjusts with block fullness, a priority fee, and a maximum fee cap; c8ntinuum uses the same developer-facing fee fields.

no_base_feefalseBase fee is enabled.
enable_height0Fee market is enabled from genesis.
base_fee222000000000.000000000000000000 (222 gwei)Starting/configured base fee value.
min_gas_price222000000000.000000000000000000 (222 gwei)Configured minimum gas price.
base_fee_change_denominator8EIP-1559-style denominator that bounds per-block base-fee movement.
elasticity_multiplier4EIP-1559-style multiplier used to derive the gas target from the block gas limit.
min_gas_multiplier0.500000000000000000Configured minimum-gas multiplier.
block_gas0Configured fee-market block gas value.
The base fee is burned. Gas parameter changes are governed through the governance module.

​
Cosmos SDK Transactions

Non-EVM (Cosmos SDK) transactions specify:
  • GasLimit: Upper bound on execution gas
  • FeeAmount: Maximum fee willing to pay
Gas is consumed during execution. If GasLimit is insufficient, the transaction fails and fees are not refunded.

​
Cross-Chain Gas

IBC and relayer integrations may introduce integration-specific fees outside normal EVM execution gas. Confirm the target IBC route and relayer policy before building user-facing fee estimates.
