Announcing Pika V4 Upgrade

Pika Protocol
2 min readJan 30, 2024

Pika Protocol is relaunching its v4 version to add new improvements and address some issues found in the previous version.

Why the Relaunch?

In our previous version, we recently discovered that a few traders took approximately $120k in profit from the vault by taking advantage of an issue found in a contract function. Our developers promptly implemented corrective measures, addressing the issue and updating our smart contracts to minimize the impact. However, to fully rectify this issue, we must redeploy our vault contract, necessitating that all depositors manually migrate their funds to the new version. Rest assured, we intend to fully reimburse those vault depositors affected and will announce details related to this shortly..

Benefits of the New Launch

Beyond addressing the identified issue, we’ve utilized this relaunch as an opportunity to introduce several improvements:

  1. Asset Upgrade: We’ve changed the vault asset from USDC.e to native USDC, minimizing bridging risks and aligning with the growing adoption from our user base.
  2. Risk Mitigation in Vault PnL Calculation: a buffer is added to store the realized PnL, and it is streamed to vault balance in a few days rather than the immediate impact to depositors. This results in more fairness and risk reduction for the vault.
  3. Enhanced Oracle Contract: Our Oracle contract has been fortified to prevent any potential impact on the vault in the rare case of L2 sequencer downtime.
  4. Future-Ready Contract: The contract has been updated to support account abstraction in our upcoming releases.

We’re pleased to share that these new contracts have undergone a thorough audit by PeckShield before deployment, ensuring an added layer of security.
