Abstract

This CIP describes a checklist to prepare to launch Compound V3 to a new EVM chain. This includes a set of quality assurance steps to ensure that the new chain meets the requirements to safely support Compound V3 and to ensure the team deploying it has completed all the prerequisites of preparing to launch. It also ensures that there is ample time for the community to deliberate and reach consensus about the market launch so that the deployment process can proceed through governance with all the available information known well ahead of time.

Motivation

This checklist is used to collect sufficient information for the community to make an informed decision on deploying markets to new EVM chains. In the past, market deployments to new chains (Polygon, Arbitrum, Base) were typically led by Compound Labs with an informal community discussion leading up to its launch. With this checklist, we can kick off a more transparent information gathering process as well as set expectations for new deployments that may be supported by any community members including through CGP grants in the Multi-chain domain.

Proposal Details

  2. Liquidity (mintable, operator, LPs, other)

  3. Verification (Natively, Externally, Locally, Other)

  4. Native message passing support

EVM Equivalence

Please describe any differences in the computing environment to Ethereum mainnet

  1. Are block times the same?

  2. Are there different transaction types?

  3. Does it include native account abstraction?

  4. What precompiles are removed and added?

  5. What notable EIPs on Ethereum are missing on the chain?

Do all opcodes behave the same?

  1. What opcodes are not included?

  2. What new opcodes are added?

  3. Are gas costs per opcode the same?

Supporting Infrastructure

What tools are available for people to better utilize the network and see its workings? Include URLs wherever possible.

For users

  1. Is there Etherscan support?

  2. Are there public RPCs?

  3. What wallet providers provide support?

For developers

  1. Is there Hardhat support?

  2. Is there Foundry support?

For Pause Guardian

  1. Is the network available on Safe Wallet (app.safe.global)?

Monitoring & Emergency Contingencies

How can users monitor on-chain activity?

  1. Is the Forta network utilizable?

  2. Is OpenZeppelin Defender utilizable?

How can users respond to network emergencies?

  1. Please list the communication details for those to contact in case of network emergency

  2. Does the network offer a way to enforce transactions (i.e., without relying on a coordinator) and/or an escape hatch mechanism?

How does the network mitigate disasters?

  1. Bridge Failure Consequence? (Frozen, self-stake, other)

Risk Assessment

  1. Please link any available audits that have been completed.

  2. Please share the network roadmap (Include recent progress and future plans)

  3. Please share the L2Beat.com url for the network if available

DeFi & Liquidity

What notable assets are on the network?

  1. Are they native or bridged?

  2. What is their TVL?

What notable DEXes are deployed?

  1. What is their TVL?

What Oracle providers are operable?

  1. Where can users assess their health?

  2. Are they pull or push based?

  3. Have they differed in behavior from the counterparts on other chains?

Considerations

  1. Proposals must first be posted in the Compound forum New Markets category.

  2. The on-chain proposal must contain a link to the corresponding forum post.

  3. Do not deploy contracts before submitting the proposal to the forum.

  4. Pause Guardian Multisig should be configured and signers should prove access before deploying contracts.

Community Checks

The community should review the following before approving a new network.

  1. Veracity of provided information.

  2. Correct configuration of any new contracts.

  3. Documentation quality.

Expected Impact

Adopting the proposal is expected to:

  • Set clear expectations for new chain deployments for teams managing deployments

  • Help identify which current EVM chains are appropriate for new Compound markets

  • Streamline and expedite the deployment of Compound to new chains

  • Help identify bottlenecks for new chain deployments that could be targeted for improvement

Security Considerations

By formalizing the requirements for new chain deployments, we intend to set clear expectations for the level of quality and safety of each EVM chain. Chain stoppages, EVM compatibility issues, and bridge disruptions are all serious risks for Compound to consider when deploying to a new environment. By collecting a large amount of information on a new chain upfront, we give ample time for the community and security stakeholders to assess its accuracy and have a high level of assurance that the chain is safe prior to actual deployment.

We’re looking for additional community feedback on this new chain checklist in its draft form before finalizing. You can also add comments and suggestions to a draft Google document here.

We’ve already shared an advance copy with the teams responsible for the Scroll and Linea market deployments.
