# `vrf` a Sway Library for verifiable random number generation
`vrf` is a simple library to access VRF implementations on Fuel, currently supporting:
- [SimpleVRF](https://github.com/darthbenro008/simplevrf)
To get started simply add it to your contract:
```
forc add vrf@0.1.2
```
and call it like so:
```sway
use vrf::{Vrf, VrfResult};
// ...
let seed = 0xd167b328cc944e4ff79f18e8f0431165; // this is a random seed you should generate yourself (most likely off chain)
let vrf = Vrf::testnet(); // or Vrf::mainnet() if you want to run on mainnet
vrf.request_random(seed);
// ... wait a while and store the seed somewhere ...
match vrf.get_random(seed) {
VrfResult::Pending => {} // we are still waiting for the number to be generated
VrfResult::Failure => {} // something went wrong
VrfResult::Success(num) => log(num), // we did generate a random number, and it is num
}
```
