Parameters and Fees
This page provides Monad mainnet parameter values for the shMonad protocol. Testnet settings may differ.
Time Parameters
Traditional Unstaking Wait Period
4 to 5 epochs in normal capacity conditions (~27.5 hours minus elapsed time in current epoch)
The actual waiting time depends on when you initiate your unstake within the current epoch and on crank progress. For the same completion epoch, a request made earlier in the current epoch has more time left to wait. If the requested MON amount exceeds the available global redemption capacity, the quote adds 2 more epochs.
Traditional Unstake Request Slots
v1.2 supports multiple active traditional unstake request buckets per user, with bounded slots to keep completion gas predictable. Requests with the same completion epoch merge, and matured requests are completed together.
Liquidity Parameters
Atomic Unstaking Pool Target Allocation: 2%
The protocol targets maintaining approximately 2% of total equity as instantly-withdrawable liquidity in the atomic unstaking pool.
This target may be adjusted over time to balance instant withdrawal availability with staking efficiency. The actual allocation may temporarily vary above or below the target as the protocol rebalances across epochs.
Validator Revenue Smoothing Duration: 2 epochs
When allocating stake to validators, shMonad smooths revenue by taking the average over the last 2 fully completed epochs.
Non-Staking Revenue Multiplier: 2x default
Non-staking revenue such as MEV, priority-fee donations, and boost payments receives a configurable multiplier in the stake allocation formula. The v1.2 default is 2x, bounded between 1x and 20x.
Staking Yield Deadband: 8,000 bps default
The allocation formula filters out 80% of each validator's expected stake-proportional staking yield by default. This reduces allocation inertia from validators that already have large stake while still counting yield above the expected floor.
Safety Parameters
Pooled Share-Rate Circuit Breaker
Selected operations are guarded so the virtual pooled shMON exchange rate cannot decrease across the operation. This protects operations that should be pooled-rate neutral or accretive, including deposits, withdrawals, traditional unstake paths, hMON conversion paths, reward paths, and isolated stake paths.
Frozen and Closed Modes
The operations Safe can freeze validator operating-loop actions or close new state-expansion paths. See Safety and Governance for the behavior matrix.
Code Upgrade Timelock: 3 days
ShMonad proxy upgrades, hMON proxy upgrades, and coinbase beacon implementation upgrades are delayed by a 3-day timelock. Immediate operational and emergency controls remain with the FastLane operations Safe.
Fee Parameters
Protocol Commissions
Staking Rewards Commission: 5%
FastLane's share of the gross staking rewards. The net remaining staking rewards are distributed as yield to shMON holders.
MEV Auction Handler Fee: 10%
The fee rate applied to successful MEV bids in the auction handler that consists of the validator's MEV commission, FastLane's MEV commission, and rewards distributed as yield to shMON holders.
Boost Yield Commission: 50%
FastLane's share of gross non-staking rewards (i.e., MEV fees, ACE fees, and other non-staking revenue streams). The remaining 50% is distributed as yield to shMON holders. For the 10% MEV auction fee, this means 5% of the total bid goes to FastLane and 5% boosts shMON yield; the other 90% still goes to the validator's coinbase contract.
This mainnet setting was verified on September 29, 2026 through getAdminValues() (boostCommissionRate = 5000 bps).
Atomic Unstaking Fees
Base Marginal Fee Rate: 0.005%
The minimum marginal rate charged even at zero pool utilization.
Marginal Fee Rate at Maximum Utilization: 1.005%
The maximum marginal rate charged when the atomic pool reaches 100% utilization.
Fee Calculation:
The marginal fee rate varies linearly between the base and maximum marginal rates as pool utilization changes. A withdrawal pays a blended fee across the utilization range it consumes, with a minimum 1 gwei fee when fees are enabled. At 50% utilization, the marginal rate is approximately 0.505%.
Important Notes
Parameter Updates:
Some operational parameters may be updated by the FastLane operations Safe to optimize performance or respond to changing network conditions. Code upgrades follow the 3-day timelock described above.
Verification:
All parameters can be verified on-chain by querying the shMonad contract. The contract code is open source and available for audit.
