Mantle Network Snapshot
Mantle is a modular, EVM-compatible Layer 2 blockchain built to scale Ethereum smart contracts, combining high throughput, low fees, and full security by relying on Ethereum for settlement.
Thanks to its modular design, Mantle separates execution, data availability, proof generation, and settlement into independent layers — allowing for innovations in scalability while inheriting Ethereum’s security guarantees.
With Mantle, developers and users get a high-performance chain that supports existing Ethereum smart contracts and tools with minimal changes, enabling faster, cheaper, and more efficient on-chain activity.
Key features
- Rollup-based scaling — Mantle batches and processes transactions off-chain, reducing gas fees, lowering latency, and increasing throughput compared to Ethereum L1.
- Modular architecture — By separating execution, data availability, proof generation, and settlement, Mantle enables independent upgrades and optimizations for each layer.
- Ethereum security through settlement & validity proofs — All state transitions on Mantle are finalized only after validity proofs and settlement on Ethereum.
- Full EVM compatibility — Developers familiar with Ethereum can deploy existing smart contracts on Mantle with minimal or no code changes, making migration smooth and frictionless.

FAQ
With Zerion API you can use the endpoint /wallets/address/positions/ to fetch all token holdings and positions (e.g. ERC-20 balances, liquidity pool positions) of a given address on Mantle.
Use Zerion API's endpoint /wallets/address/nft-positions/ with the chain filter for Mantle. It will return all NFT assets held by the wallet on Mantle.
Yes, with Zerion API you create a webhook for an address to listen to all transactions from that address. You can listen to transactions from just Mantle or from all supported chains.
No — the same Zerion API endpoints (/wallets/address/positions/, /wallets/address/nft-positions/, etc) apply across supported EVM-compatible chains, Mantle included.
