Switchboard x Evm
Contractâ
The Switchboard EVM contract implements EIP-2535 Diamond Pattern to facilitate a modular contract design allowing each module to be updated and maintained individually. This allows Switchboard's EVM contract to be used across blockchains with different engineering constraints. Each module is a facet that can be added to the contract to give it additional functionality.
Switchboard is currently deployed on the following chains. Check out The Network page to see all of the Switchboard supported chains along with the Switchboard Labs operated queues.
Arbitrum
Aurora
Core
Getting Startedâ
The switchboard-xyz/evm-sdk contains the EVM specific SDKs and examples for operating Switchboard.

Functionsâ
Switchboard Functions allow you to execute your own code off-chain in a verifiable manner allowing you to build more dynamic programs. This allows you to publish ANY data you want on a cron-based schedule, perform basic maintenance operations, and execute async operations for your users! This lets you have users interact with your program then perform async checks off-chain to prevent data staleness and oracle extractable value attacks. Switchboard Functions are flexible enough for any use case you can imagine without sacrificing security.
Data Feedsâ
Switchboard Data Feeds allow you to permissionless publish a data point on-chain for use with your smart contracts. These values are published at a periodic interval such that your users do not need to wait for any off-chain execution in order to consume the values.
