EVM on Flow

Breaking Down Barriers for New Developers to Flow

The EVM on Flow upgrade enables for tools to simply connect and use Flow like any other EVM based network. Empowering developers to use the same tools across networks for their multi-chain projects. Making Flow as easy to onboard as EVM L1 or L2.

Unleash EVM with Flow Native Features

The EVM on Flow upgrade allows EVM applications to tap into the powerful features of Flow and build beyond limitations of Ethereum and the programming limitations of Solidity. Day one of running on Flow, apps will get mainstream scalability without sharding, fast and cost effective transactions and MEV resilience without a code change.

Build Simply

EVM on Flow will allow for developers to easily compose the above features and capabilities of Cadence on top of existing tooling and smart contracts developed in Solidity for Ethereum and other EVM-compatible networks.

Lift and shift from Ethereum to Flow, lowering the barrier for entry for tools and platforms on Flow will bust through the onboarding challenges to Flow previous to Crescendo.

Liquidity, DeFi use cases, and platform integrations will seamless come to Flow. With EVM on Flow building is as easy as any EVM chain (L1, L2, L3’s).

EVM equivalence means more than compatibility, EVM compatibility is frequently an empty promise. EVM on Flow is the same as building on Ethereum Mainnet.

Same wallet and same keys on Flow, with EVM on Flow now wallets across EVM can run on Flow. Use Metamask, or Coinbase as simply as adding a new network.

Unlock What is Possible

Mainstream user experience, meeting the mainstream is what Flow does best. With EVM on Flow now world class experiences are possible for all developers across web3.

Extend Solidity with the power of Cadence, applications that have been built in Solidity now can be extended and composed on within Cadence with simple wrappers. Continuously and incrementally delivering a best in class product.

Seamless connectivity between EVM and Cadence, assets are unconstrained. Applications live where they choose moving assets across environments atomically.

Interact across smart contracts and environments atomically, using Flow scripted transactions. Sophisticated interactions across smart contracts as wel las across EVM and Cadence can be abstracted away in a single click.

How it Works

JSON.RPC API Gateway

Applications simply update their RPC endpoints to a Gateway and they are running on Flow. The gateway transforms and translates across EVM API and Cadence API for a fully integrated and native ability to run on Flow. To learn more read here.

Cross VM Bridge

Is made possible by a smart contract protocol which facilitates arbitrary token interchange between VM environments. By introducing a new EVM account type, which has a programmable proxy on the Cadence side through which interactions with EVM are mediated, comes the ablility to orchestrate and compose EVM transactions within a Cadence one.

Cadence Owned Accounts

EVM has classically had Externally Owned Accounts (EOA) and Smart Contract Accounts (SCA) both of which will work the same on Flow. Cadence Owned Accounts are a new type of EVM Smart Contract Account empowering EVM on Flow to evolve and have accounts benefit from all of Flow’s native account abstraction.

Two Environments, One Token

EVM on Flow introduces a whole new environment for users and developers to interact with but gas is paid with Flow token across both. No risk of swap depth and liquidity across, simply use Flow.

Flow EVM

With Flow’s focus on mainstream applications there is an extreme importance to be fast. With this Flow achieves hard finality in about 20 seconds.

Understanding Transactions Time

Cost

~$2 average transaction cost

Eth
Mainnet

Flow EVM

With Flow’s focus on mainstream applications, it must be cheap for users and app developers. Flow averages ~$0.000015 for the average transaction. Flow also naively enables ways that developers or wallets can directly pay any transaction costs for a user.

Scale

With layer 2 solutions

Eth
Mainnet

Ethereum’s proposed evolution parallels Flow’s existing design: Flow’s Execution Nodes are akin to “Rollups,” Collection Nodes resemble “Data Availability Shards,” and Consensus Nodes correlate to the “Beacon Chain.”

Flow has achieved these improvements in production for the last three years - synthetic Flow benchmarks have achieved ~1k TPS leaving a significant amount of available throughput for applications today.

Storage

With layer 2 solutions

Eth
Mainnet

Flow’s current ~700GB of state space is extensible to the petabyte scale and allows contracts to maintain large amounts of data alongside logic at low gas rates. This has added convenience to developers who can forego off-chain metadata integration.

MEV Resistance

Eth

Flow natively provides censorship & MEV resistance which is achieved by designating specific validators for building transaction bundles that are separated from the validators proposing blocks. Learn more.
