# Deposit

The vault receives assets from depositors and invests in an options strategy. There will be a min deposit time to process the deposits into the vault. All vaults are now tokenized with corresponding ERC-20 tokens to represent user balance. The net Asset Value (NAV) of the vaults is calculated to price the vault tokens. These vault tokens can be integrated into the rest of DeFi since the vault tokens act as a yield-bearing asset on the deposit token; the possibilities are endless.

Users can deposit into vaults from

**Vault capacity**

Polynomial Earn vaults are capped at a $1 million capacity. Deposit from a unique address is uncapped.

#### Min deposit time

Since there is no round system in the newer version, there will be a min deposit time to enter into the position. The min deposit time ranges between 4 hours.
