Learn how to build fast, scalable, and secure dApps on Fantom. Fantom is EVM compatible.

What is Fantom?

Fantom is a fast, scalable, and secure smart contract platform built on an aBFT consensus protocol.

Fantom is:

  • Permissionless

  • Decentralized

  • Open source / Business Source License

Lachesis, its revolutionary aBFT consensus mechanism, allows Fantom to be faster and cheaper than previous technologies while retaining security.

Key features


Fantom achieves transaction finality in 1–2 seconds on average.


Fantom can process thousands of transactions per second and scale to hundreds of nodes.


Lachesis provides institutional-grade security to the distributed network. Fantom offers absolute finality, which means that transactions can never be reverted like in networks with probabilistic finality.

Fantom is also leaderless. By removing leaders, security does not rely on a small set of actors in charge of block production.

Smart contract support

Fantom is fully compatible with the Ethereum Virtual Machine. Developers can create and deploy smart contracts as they would on Ethereum.
