[BIP-37] Allocate BAL Liquidity to Polygon & Arbitrum Multichain Bridge


As you may recall BIP-3 allocated 40k BAL towards Ethereum<>Optimism bridge liquidity on Multichain. Since then this liquidity has seen fairly good usage. I reached out to Multichain to add Polygon & Arbitrum support to their router which is now operational - it just needs to be seeded with BAL liquidity so users can start bridging.

I think it’s valuable to be able to easily transfer BAL between all of Balancer’s deployments, plus this puts to work idle BAL in the Treasury as we do earn bridging fees on all of this activity. As BIP-19 begins to drive more adoption for us on Polygon & Arbitrum it is reasonable to expect an increased demand in bridging BAL between networks.


If approved, the DAO Multisig 0x10A19e7eE7d7F8a52822f6817de8ea18204F2e4f will send 40,000 BAL to the liquidity mining multisig 0xc38c5f97B34E175FFd35407fc91a937300E33860. From there, the Maxis will bridge 20,000 BAL to Polygon and 20,000 BAL to Arbitrum then supply liquidity to Multichain.


this proposal makes sense to me, there is some risk the BAL could be lost, however i think the flexibility of bridging BAL between chains outweighs that risk

minor-ish update here

liquidity providers to multichain’s pools actually do not earn any fees. all fees go to the multichain protocol.

of course there are second order benefits here, since if someone bridges BAL they will presumably trade it or provide liquidity with it on one of our deployments.

It is a shame we do not get bridging fees but it is well worth having BAL be easily accessible on the networks we are deployed on. I am in favor of this.

Just for general knowledge, any reason for 20k allocated to each when Optimism was 40k?

that proposal was 20k on Ethereum, 20k on Optimism. 40k total

Even though we do not earn fees, we also agree that having a small amount of BAL in these pools is worth it to make it easier for users to bridge.

We are in favor of this.
