Mantle (MNT)

What Mantle is

Mantle (MNT) is the native token of Mantle Network, an Ethereum-compatible layer 2 built as a zero-knowledge validity rollup. MNT pays gas on the network and, in the wider Mantle ecosystem, serves "as the cornerstone for governance, staking, and driving innovation" (source: Mantle, September 2026). The network's modular design separates execution, data availability, proof generation and settlement into independent components.

Mantle is unusual among layer-2 networks in that the project is also a large treasury and product group. Alongside the rollup sit a liquid staking protocol, a Bitcoin bridge, an index product and a consumer payments application.

How it works

Mantle Network runs the Ethereum Virtual Machine, so contracts and tools built for Ethereum work with minimal modification. Where it differs is the proof system and the way data reaches Ethereum.

Transactions flow through remote procedure call nodes to a sequencer, which orders them and produces rollup blocks. A batching component periodically collects those blocks, compresses them, and submits them to Ethereum using blob-carrying transactions under EIP-4844. The blob commitments posted on-chain serve as the canonical data reference. A separate proposer submits zero-knowledge validity proofs to a contract on Ethereum. Once the settlement contract verifies a proof, "the batch achieves immediate finality without requiring any challenge period."

That last point is the practical difference from an optimistic rollup. There is no seven-day dispute window built into the design, because correctness is proved mathematically rather than assumed and challenged.

The transaction pool is private. Mantle keeps the mempool non-public and routes submissions to the sequencer, a decision the documentation ties directly to limiting mev extraction. The sequencer processes transactions by base fee and priority fee.

Fees have three components after the Arsia upgrade: an L2 execution fee, an L1 data fee and an operator fee. The L1 data fee was redesigned to estimate actual data-availability size by compressing transaction data and mapping the result through a regression, replacing a flat overhead model that overcharged. The operator fee is a configurable charge for sequencing services collected by a dedicated contract. Arsia also made the EIP-1559 base fee dynamic rather than fixed, with parameters carried in each block's extra data, and added a data-availability footprint scalar so data-heavy blocks are not underpriced.

MNT itself became the network's native gas token in the Mantle v2 Tectonic upgrade, which moved from an ERC-20-based scheme to a native token model aligned with how ether works on Ethereum. The documentation gives the reason as "closer alignment with Ethereum's native design," simplifying development and integration.

Supply and tokenomics

MNT's roles are gas on Mantle Network, governance across the Mantle ecosystem, and staking. This page does not state a total or maximum supply figure for MNT, because the project's technical documentation does not publish one; read circulating supply and total supply from the data on this page or from a current Mantle disclosure.

What the project does publish, and updates continuously, is its treasury. The EcoFund figure below is a separate pool, supported by professionals from Mirana Ventures and connected to twenty venture funds.

A treasury holding roughly seven in ten dollars of its value in its own token is a fact worth sitting with. It means the treasury's reported size moves with MNT's price, and that the largest holder of MNT is the project itself.

History

Mantle Network launched as an optimistic rollup and was, by the project's description, "the first adopter of EigenLayer and EigenDA," using an external data availability layer rather than posting data to Ethereum directly.

It has since been rebuilt in stages. Tectonic made MNT the native gas token, introduced a private transaction pool and added EIP-1559 transaction support. Later upgrades migrated data availability from EigenDA to Ethereum blobs, moved the proof system to zero-knowledge validity proofs with an accompanying transition in the withdrawal period, and, in the Arsia upgrade, replaced the legacy fee model while activating the equivalent of Optimism's Canyon through Jovian forks to bring the protocol layer in line with the current OP Stack. A further upgrade, Limb, addressed compatibility with Ethereum's Fusaka fork.

The wider group expanded alongside the chain: the mETH Protocol for liquid ether staking and restaking, Function for bringing bitcoin into the ecosystem, Mantle Index Four as a yield-bearing basket product, UR as a consumer spending and off-ramp application, and MantleX for artificial intelligence work.

Risks and what to watch

Sequencer centralization is the standard layer-2 risk and applies here. A single sequencer orders transactions and a single proposer submits proofs. The private mempool that limits MEV also concentrates visibility in the operator.

Rapid architectural change is the second. Mantle has switched data availability providers and proof systems, and revised its fee model, within a short period. Each migration is an opportunity for bugs, and each requires users and integrators to update. The withdrawal period changed alongside the proof system, which is exactly the kind of detail that catches people out.

Third, treasury concentration. With roughly 72% of the treasury denominated in MNT, the project's funding capacity and its token price move together. That is a reflexive relationship in both directions.

Fourth, the operator fee is a new, configurable charge set through system configuration on Ethereum. Configurable fees can be changed, and users should know that the total cost of a transaction now has three parts rather than two.

Finally, bridging risk. Assets on Mantle arrive through bridges, and withdrawals depend on the settlement contracts working as designed. Check which bridge you are using and what its assumptions are.

Frequently asked questions

Is Mantle an optimistic rollup?

Not any more. Mantle Network is now a zero-knowledge validity rollup. Validity proofs are verified on Ethereum, and a batch reaches finality once verified, with no challenge period.

What does MNT do?

It pays gas on Mantle Network and serves as the ecosystem's governance and staking token. It became the network's native gas token in the Mantle v2 Tectonic upgrade.

Where is Mantle's transaction data stored?

On Ethereum, in blobs posted under EIP-4844. Mantle previously used EigenDA and migrated data availability to Ethereum blobs.

What is the operator fee?

A third fee component introduced in the Arsia upgrade, charged for sequencing services and collected by a dedicated contract. Total transaction cost is now the L2 execution fee plus the L1 data fee plus the operator fee.

Where can I buy Mantle?

MNT is listed on a range of centralized venues and trades on decentralized exchanges. See where to buy Mantle for availability where you live, and Exchanges for how those venues compare.
