Arbitrum is an L2 that, like Optimism, promises the security of Mainnet Ethereum with a fraction of the gas cost. Arbitrum has over twice the TVL of Optimism, and it has no token, yet. Things are heating up on Arbitrum with the start of their Odyssey campaign this week.


@drcpu, @max’, and I share an excitement for Arbitrum and we have started the work to deploy to Arbitrum testnet. The contracts are live, the subgraph is up and we have started to integrate the API, Defender, and UI. To proceed further with the testnet deployment we need to work with PT Inc to update the official packages and repositories. See below for deployment details.


Through Project Optimism we, as a community, have gained a better insight into the process of deploying the PT V4 codebase. It’s a complex system that has been designed well to scale!

Project Optimism’s initial budget for deployment was $15,400. The bounties thus far have totalled $9,800 USDC and roughly 1k POOL (under budget!). We believe we can halve this cost and have Arbitrum deployed by 2-3 people for ~$5k.

Go forward?

In the event that there is consensus to proceed with a launch on Arbitrum we would pursue a grant to fund deployment. The community should consider how to market the expansion - contacting Offchain Labs, meme competition, etc.

We would like to hear from you! Do you share our excitement for deploying PoolTogether to Arbitrum?

Awesome stuff to hear! The 3 of you are real MVPs. I fully support the funding for the Arbitrum deployment!


For the record, I hit the mouse button on “Yes” really hard.


YES, YES and YES :smiley:

(*Post must be at least 20 characters xD)


Really excited to see this!! I have one consideration before voting…

I assume both networks are prioritizing “native” applications. They likely will be less interested in giving incentives if we are deployed on both.

It might be worth reaching out to one (or both of them) to understand how being deployed on both might impact incentives and if they have a preference on how to best work together…


I think deploying to Arbitrum before their airdrop/incentives start is a great idea!

We missed out on it with Optimism.


I don’t think we’re considered Optimism native as of now.

We already come from Ethereum/Polygon/AVAX.

Unless you’ve spoken to someone from Optimism that said otherwise?


Very happy to see this happening for many reasons:

  • All three of you (and @McOso, too) have done great work for the community and the protocol. Even though half of you are full-anon you are some of the voices I trust the most.
  • The offer is more than humble and proves the project comes out of motivation to improve the protocol rather than filling your pockets with treasury funds
  • Moving between L2s seems to become a frictionless and cheap process
    – I believe LI.FI’s suggestions could become even more interesting

We should support you in supporting the protocol. To me, this is a logical step to retain you as long-time core contributors and help you learn the skills both you and the protocol need.

Deploying on two networks in a short period of time sure means more work for the community. But the current narrative around PoolTogether is strong, positive and people are watching. The timing seems to be good!
