Switchboard x Solana


Switchboard V1 was the first oracle network deployed on Solana mainnet in May 2021. The Oracle Program supports data feeds and verifiable randomness using a round-robin queue of off-chain oracles fulfilling update request. The Attestation Program supports functions, secrets, and legacy data feeds using an attestation service to verify that the execution of off-chain code was conducted within a trusted execution environment (TEE).

You can find the program IDs for these deployments below, or check out The Network page to also view the Switchboard Labs supported oracle networks.

Getting Started​

The switchboard-xyz/solana-sdk contains the Solana specific SDKs and examples for operating Switchboard.

git clone


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 Feeds​

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.

Verifiable Random Function​

Switchboard's Verifiable Random Function (VRF) on Solana allows you to request randomness and execute a subsequent user defined callback on fulfillment. This ensures your users are always consuming a newly provided randomness value, preventing a malicious user from waiting for a favorable value and gaming your smart contract.

This is very computationally intensive and requires 48 transactions to verify on-chain. Users should instead use the Randomness Callback Function to generate randomness in a single transaction at 1 / 20 of the cost!
