# FAQs

#### Where can I find more information about the protocol's design?

A detailed overview of the PoolTogether V5's design can be find [here](https://dev.pooltogether.com/protocol/design/).

#### What are the protocol's contract addresses?

Click [here](https://dev.pooltogether.com/protocol/deployments/mainnet) for a comprehensive list of all the deployed contract addresses on different networks.

#### What is ERC-4626?

ERC-4626 is a tokenized vault standard. Vaults are smart contracts that take in token deposits, use them for some underlying yield mechanism and provide receipt tokens to users so that they can redeem their share of the deposits and yield.

Standardizing vault implementations makes it easier for applications, plugins, and tools to integrate with vaults. Rather than building many custom adapters for each vault implementation, applications can easily build on top of any vault following the ERC-4626 standard. PoolTogether V5 does exactly that.\
\
PoolTogether V5 can utilize any ERC-4626 vault as the underlying yield source for a Prize Vault. This means any protocol which is ERC-4626 compatible can be integrated with PoolTogether, and thus any token which can be deposited into that yield source, can in turn be integrated with PoolTogether V5 as a deposit token.

#### Where do the Prize POOL vault's prizes come from?

Prize POOL is essentially staked POOL. The przPOOL vault wins prizes based on a variable percentage (\~3% to \~10%) of the total yield from the Prize Pool each day. This means that the more successful a Prize Pool is, the more WETH prizes you can win by staking your POOL!
