zkSync allows cheaper and faster access to Gro Vault

Argent has integrated Gro as one of its zkSync launch partners. Initially Argent on zkSync is offering Gro's high yield leveraged Vault product.
zkSync is a Layer 2 scaling solution that offers cheaper and faster transactions than the main Ethereum blockchain (Layer 1). Layer 2 solutions move most activity away from Layer 1, while still inheriting its security and finality.
zkSync uses less gas than either Layer 1 transactions or ‘optimistic rollups’ (e.g. other Layer 2 solutions like Arbitrum or Optimism). You can read more about it from Argent.

Why is the dollar value shown on Argent less than what I've deposited?

This could happen occasionally since the dollar value displayed on Argent wallet comes from our Uniswap USDC pool for PWRD and Vault respectively. As these tokens get traded, the pool price could go off-peg to the actual value of the tokens. When this happens, arbitrage would take place and would bring the value back very close to what you'd get if you were to withdraw your Vault or PWRD on our dApp.
On top of this, USDC/USD exchange rate also fluctuate at times, adding another contributing factors to having an inaccurate value shown in your Argent wallet.
The best way to check your Vault and PWRD total value would be on Gro protocol as it reflects the value you could redeem from the protocol should you choose to withdraw funds. Argent users can connect to the dApp through WalletConnect to check the total value as well.

Reminder about Risk

DeFi is still a very new space, and while that's exciting, it comes with risk. Gro Protocol's software helps you access this world, but make sure you do your own research and only supply assets you can afford to lose.
