StableNet runs a modified EIP-1559 fee model where all fees are denominated in WKRC (KRW-pegged) and the priority fee is set by governance rather than market competition.

Gas Mechanics

​
Base fee

The base fee adjusts ±2% per block based on the parent block’s gas utilization:
UtilizationAdjustment
> 20%+2% per block
6% – 20%unchanged
< 6%−2% per block
This is far more gradual than Ethereum’s ±12.5% at 50% utilization. Under normal load, the base fee is stable. The base fee is not burned. It is paid to validators. Stablecoin supply only decreases through explicit, governance-approved burn operations at fiat redemption.

​
Priority fee

The priority fee (gas tip) is not a user-competitive value — it is enforced by the GovValidator system contract. For regular accounts:
  • Your maxPriorityFeePerGas is overridden by the governance-enforced tip.
  • Transactions below the minimum tip are rejected.
  • You cannot pay extra to jump the queue.
Authorized (operational/system) accounts may specify a custom tip and receive priority based on their actual tip value.

​
Effective gas price

effectiveGasPrice = baseFee + min(governanceTip, maxFeePerGas − baseFee)
For fee-delegated transactions (0x16), the effective gas price is charged to the fee payer’s account.

Fee Query APIs

These standard JSON-RPC methods return StableNet-specific values:
MethodReturns
eth_maxPriorityFeePerGasGovernance-enforced gas tip (e.g. 27,600 gwei)
eth_gasPriceRecommended price: baseFee + governanceTip
eth_feeHistoryHistorical base fees and utilization
You can use these with any standard Ethereum library:
Replace RPC_URL with the endpoint from Network Information.
const provider = new ethers.JsonRpcProvider(RPC_URL);

// Get the current governance tip
const tip = await provider.send("eth_maxPriorityFeePerGas", []);

// Get recommended gas price
const feeData = await provider.getFeeData();

​
Fee Delegation

StableNet supports gasless UX flows through fee delegation (FeeDelegateDynamicFeeTxType, type 0x16). The fee payer signs alongside the sender, and all gas costs are charged to the fee payer’s balance. See Fee Delegation for usage and signing details.
