> **CAUTION: Migrate to VRF V2.5**
>
> VRF V2.5 replaces both VRF V1 and VRF V2 on November 29, 2024. [Migrate to VRF V2.5](/vrf/v2-5/migration-from-v1).

Chainlink VRF allows you to integrate provably-fair and verifiably random data in your smart contract.

For implementation details, read [Introduction to Chainlink VRF](/vrf/v1/introduction).

## Polygon Mainnet

> **TIP: Important**
>
> The LINK provided by the [Polygon Bridge](https://wallet.polygon.technology/bridge) is not ERC-677 compatible, so
> cannot be used with Chainlink oracles. However, it can be [**converted to the official LINK token on Polygon using
> Chainlink's PegSwap service**](https://pegswap.chain.link/)
