# Cardinal

## What is Cardinal?

Cardinal is a protocol on Solana that has built a utility layer for NFTs. They have built NFT utility infrastructure such as staking, ticketing, renting, and identity verification, which are all key primitives that push forward both the Solana ecosystem and NFT adoption.

## How do Squads Protocol users benefit from this integration? 

We've integrated Cardinal to allow users to link their Twitter profile to their wallet address within their Squad. Cardinal adds an **important social dimension** to Squads Protocol, which is essential for effective coordination and accounting**.** With Twitter-linked identities, navigating between owners in a Squad and keeping track of their activity is straightforward.

Additionally, Squads Protocol users are able to **rent their NFTs** directly from the Squad without withdrawing them from the vault. 

## How to link Twitter to your wallet address?
