Fees & Model

How Monadinals fees work, where they go, and the full cost breakdown for every operation type.

Fee structure

Every Monadinals operation requires two types of fees: a fixed protocol fee paid to the MonadInscriptions contract, and a small variable network gas fee paid to Monad validators.

Protocol fee (per operation)10 MON

Estimated gas (Deploy)~0.001 MON

Estimated gas (Mint)~0.001 MON

Estimated gas (Transfer)~0.001 MON

Total per single operation~10.001 MON

Gas is negligible

On Monad, gas costs are a fraction of a cent. The dominant cost is always the flat 10 MON protocol fee. For cost planning, you can safely approximate total cost as 10 MON per inscription.

Protocol fee

The 10 MON protocol fee is enforced on-chain. If you submit a transaction with less than 10 MON as msg.value, the contract will revert and the transaction will fail — no fee is charged, no inscription is recorded.

The fee applies equally to all three operation types: Deploy, Mint, and Transfer. There is no fee discount for deployers or bulk operations at the contract level.

Fee is non-refundable

If an inscription passes on-chain validation but is rejected by the indexer (e.g. minting beyond max supply), the 10 MON fee is still consumed. The contract does not know about indexer-level rules and cannot issue refunds. Always verify parameters carefully.

Bulk mint costs

When using the Repeat field to send multiple mint transactions, the total cost scales linearly with the repeat count. The Inscribe panel displays the breakdown before you confirm.

1 mint10 MON

5 mints50 MON

10 mints100 MON

25 mints250 MON

50 mints500 MON

100 mints1,000 MON

These figures exclude gas, which adds approximately 0.001 MON per transaction.

Where fees go

Protocol fees accumulate in the MonadInscriptions contract. The contract includes a withdrawal function callable only by the designated protocol treasury address. Fees are used to:

Fund ongoing development and protocol maintenance
Support indexer infrastructure and uptime
Cover future smart contract audits and upgrades
Build out the Monadinals marketplace and ecosystem tools

Why a fixed fee?

A flat fee model was chosen for several reasons:

Predictability

Users know exactly what each inscription costs. No gas estimation surprises or fee spikes during congestion.

Simplicity

A single number is easier to reason about than dynamic fee curves. The Inscribe UI can display exact costs without estimation.

Spam prevention

A non-trivial fee discourages low-effort ticker squatting and spam minting that would bloat the indexer's event log.

Sustainability

Protocol revenue scales directly with usage, giving the team a sustainable funding model without needing token sales or VC investment.

Network gas fees

In addition to the protocol fee, each transaction pays a standard Monad gas fee. Because Monad targets sub-cent gas costs at 10,000 TPS, this fee is negligible in practice. Estimated gas ranges:

Gas limit (approx)~80,000 gas

Gas price (base)~0.0000001 GWEI

Gas cost (approx)< 0.001 MON

Gas estimates are approximate and may vary depending on payload length and network conditions. The Monadinals contract is optimized to minimize gas usage.

Future fee changes

The current fee of 10 MON per operation may be adjusted in future protocol versions based on MON price, network conditions, and community feedback. Any fee changes would require a contract upgrade and would be announced well in advance. The current v0.1 fee parameters are fixed for the duration of the testnet phase.
