ZKSpace (ZKS)

The ZKSpace platform consists of three main parts: a Layer 2 AMM DEX utilizing ZK-Rollups technology ZKSwap v3, a payment service called ZKSquare, and an NFT marketplace called ZKSea.

Audits & Exploits

• Bug bounty program can be found [insert here].
• From L2beat (13-10-2022):

"Funds can be stolen if…

1. the cryptography is broken or implemented incorrectly,
2. a contract receives a malicious code upgrade. There is a 8 days delay on code upgrades,
3. the source code of unverified contracts contains malicious code (CRITICAL).

Funds can be lost if…

1. the user is unable to generate the non-trivial zk proof for exodus withdraw.

Users can be censored if…

1. the operator refuses to include their transactions. They can still exit the system.

MEV can be extracted if…

1. the operator exploits their centralized position and frontruns user transactions."

Governance

Admin Keys

• From L2beat (13-10-2022):

"In addition ZK-SNARKs require a trusted setup to operate. The system has a centralized operator. The operator is the only entity that can propose blocks. A live and trustworthy operator is vital to the health of the system.

Force exit allows the users to escape censorship by withdrawing their funds. The system allows users to force the withdrawal of funds by submitting a request directly to the contract on-chain. The request must be served within a defined time period. If this does not happen, the system will halt regular operation and permit trustless withdrawal of funds. If enough time passes and the forced exit is still ignored the user can put the system into Exodus Mode, disallowing further state updates. In that case everybody can withdraw by submitting a zero knowledge proof of their funds with their L1 transaction.

The system uses the following set of permissioned addresses:

1. zkSpace Admin 0xfCAE…05Be (EOA) This address is the master of Upgrade Gatekeeper contract, which is allowed to perform upgrades for Governance, Verifier, VerifierExit, PairManager, ZkSeaNFT and ZkSync contracts.
2. Active validator 0x5bd9…41E2 (EOA) This actor is allowed to propose, revert and execute L2 blocks on L1. A list of active validators is kept inside Governance contract and can be updated by zkSpace Admin."

How it works

• From L2beat (13-10-2022):

"Each update to the system state must be accompanied by a ZK Proof that ensures that the new state was derived by correctly applying a series of valid user transactions to the previous state. Once the proof is processed on the Ethereum blockchain the L2 block is instantly finalized. All the data that is used to construct the system state is published on chain in the form of cheap calldata. This ensures that it will always be available when needed."
