[CIP#62/63] Multi chain gauges, to spread the CRV love on side chains and L2s

Proposals
#1

Summary:

As Ethereum remains expensive to use and out of reach for many users discovering the wonderful world of DeFi, Curve has found itself porting on Fantom and Polygon with other chains planned. One of the issue with this is that finding deep enough liquidity without a new token or rewards can be difficult when a lot of protocols can offer high APYs as they launch and begin their emission schedule.

We explored different options to do so, many presenting issues and others good compromises like Ellipsis which rewards Curve and its holders but eventually we reached the conclusion that the better solution was to offer CRV rewards which is difficult as CRV has strict inflation schedule.

Eventually, a solution was developed which would allow to create gauges on other chains. Much like current gauges, veCRV holders could vote for them to assign CRV to them and stakers on respective chains would then receive it. Those gauges can be killed meaning if a chain was to fail, the DAO could choose to turn off CRV rewards.

This system could be used for all side chains and L2, present and future, and would allow veCRV holders to vote weight any gauge on any chain from Ethereum which will always remain the heart of Curve.

This thread is here to discuss why anyone might think this is a bad idea or if there are any issues we might have overlooked.

Incentive for providing liquidity on ftm.curve.fi

This makes sense - keep Ethereum L1 as the main chain where veCRV exists and governance happens, but still be able to influence rewards on other chains (which might generate more fees for veCRV holders than ETH_based pools). :+1:

It’s inevitable that Curve expands on other EVM compatible chain, so this feels future-proof.

There might be a question later on where fees should be claimable for token holders (L1 vs L2), or even whether users can submit their votes with their L1 veCRV balance on an L2 to save on high gas fees to vote…

Agree, Curve has to place position of rising cross-chain liquidity and bridging market.

ageree,awesome,Hope to pass the proposal as soon as possible.

Agree. More incentive for L2 users would largely improve Curve’s influence on DiFi.

PS: StakeDao already did it in their polygon network, which helps them attract more than 28 million in few days.

Sounds good. With that model, does an user have to claim their CRV from Ethereum or can they claim from the L2/sidechain ?

#7

Claim would happen on respective L2/sidechain

any chance depositors on Polygon will get CRV rewards retrospectively once the proposal passes?

#9

It’s a great idea I support this

#10

Gauges for other chains is a great solution; but curious how it actually works. It would seem like one would have to migrate a block of CRV to the L2 prior to the week start; or how would one mint from L2 and have the minter on L1 be an accurate reflection?
Since you can’t know what the vote will be till one needs to begin emitting the block of CRV it would seem that it would need to be delayed compared to L1 somehow.
Again…just thinking out-loud; curious how L2 can mint and have accurate reflection on L1.

Additionally; this has the added risk of one day these side-chains becoming defunct, forever orphaning potentially a large amount of CRV that will never again be part of Quorum. Perhaps an argument for a set of abstraction tokens that are “redeemable” for L1 CRV somehow.

Gauge checks results of gauge weight then mints CRV owed for the entire week and then sends it to over the bridge essentially.

I see; hence the mention about strict emissions, I suspect this requires a change to the minter itself to allow pre-minting.

So, we should treat this similarly to a white-listing in terms of risk. If Poly goes belly up, all that CRV sitting there is lost to vote forever.

#13

Would be possible for DAO to change the gauge type and making it so it wouldn’t be capable of minting anymore CRV so a week or two of emissions could be lost for a specific gauge at most.

Curvepools everywhere, discriminate against no chain. The multichain market needs multichain and cross-chain protocols.

Now if sidechain operators get to incentivize liquidity with their native token too that would be optimal.

Perfect yes please :pray:

#18

Would be nice to be able to collect protocol fee rewards on L2 or Ftm etc if possible. That would be something special.

#19

I agree with many other comments. I have one question (or rather vision). Would curve use existing bridges or create a bridge?

I suggest to build a curve bridge to any other blockchain. This bridge could be offered as a service to the defi world.

Curve would expand its business model from stable swap to stable swsp and (stable) bridge. would be a huge service snd likely a boost for vecrv :slight_smile:

#20

Would be very interesting to see this, Ethereum remains the main liquidity source and layer for DeFi compostability with the support from other EVM compatible solutions to form a giant future of France network.

Expanding to all side chains and L2 are meaningful for adoptions and kick-start the multichain universe with the veCRV holders controlling the decisions.
