I think 2pool makes sense, and increases the capital efficiency of pools connected to it.
However in my opinion it makes sense to make this base pool natively connected to AAVE or Compound lending.
A yield bouncer feels like it adds too much risk, but base lending feels relatively safe at this point.
2pool would be good to offer as a basepool, the marketcap of USDT/USDC dwarfs the other stables, and while DeFi stablecoins rise and fall, those two will likely continue to scale and see wide adoption.
4pool should also be offered as a basepool, UST/FRAX and the other protocols pledging support for this pool (redacted/ohm etc) make up a significant amount of protocol ownership over Curve. They appear to be willing to heavily incentivize this as a basepool. If they’re willing to do what they can in their combined power to turn this into the default basepool, they should have that option available to them. It’s much riskier to Curve allowing this to become the default basepool, but it’s important for Curve to remain neutral and let tokenholders dictate its future.
Can we run some benchmarks comparing the 2/3/4 pool setups vs each other in various scenarios with same total liquidity and amplification factor.
I think its important for the community to have the clearest picture of how these pools impact the Curve ecosystem.
Risky in the sense that half that pool would be smaller-cap algo stables? Or risky to have a 4pool be the basepool as opposed to a 3 (or a 2) pool?
Does adding more assets to the basepool strengthen, weaken, or have no effect on stability is what I am genuinely not sure about.
On 2pool implementation
2pool base implementation makes a lot of sense: DAI has had a good time freeloading off of Curve (meanwhile their public community has done nothing but shit on Curve) and has not expanded in a way that is appreciable for today’s needs. We expect that most swaps in the 3pool are between USDT and USDC anyway (needs to be verified). 2pool helps Curve expand much further and not get dragged down by DAI’s slack (DAI is still a cool stablecoin tho). For reference:
Having stable-2pool implementation would allow other algo stables to expand as well, upending DAI’s dominance. This is something we look forward to: stablecoins are a very interesting financial engineering attempt at damping the volatility of an asset to zero (depending upon use case), and there is no one way that’s the best (they must all be encouraged in this grand DeFi experiment). Alas, DAI (being as cool as it is, regardless of how toxic its community is) has not managed to grow as much as centralised and regulated stablecoins have.
On 4pool implementation
The combo with unproven algo stablecoins in their nascent stage is … questionable. UST does plenty volume for reasons that are not organic (either ponzi-buying BTC from CEXes or trying to repeg the pool after replenishing Anchor’s yield reserves). Frax on the other hand has been dumping CRV and calling it profit, while announcing to the world that they’re aligned with Curve. Curve can live without FRAX, the other way around is questionable.
While we wonder if something like 4pool is worth it, it should be given a shot regardless. 2pool would make Curve a bit more neutral. People who want DAI can always go the 3pool route (that will not change). People who are a bit more risk on can choose the 2pool-FRAX-UST route, if it provides more yield.
With 4pool metapool, the question is: who’s going to build it? What about fee burners? will veCRV holders receive 3CRV or 2CRV?
Finally: who’s willing to build curve from scratch?
I think 2 Pool USDC/USDT is a great idea. Stop supporting 3 Pool and let DIA stand on its own. Curve has helped build DAI liquidity and demand for far too long. A USDC/USDT Meta Pool will be a good foundation for any DAO to make combinations for a 3 pool or a 4 pool.
I concur that 3CRV as a sole stable coin metapool is unfairly incentivizing Dai liquidity without incentivization to veCRV or vlCVX holders. Addition of a 2pool or 4pool implementation is logical.
One question that arises is: Would it be possible to pivot payments to veCRV into one of these other metapool tokens down the line if needed? i.e pay revenue in 4 pool or 2 pool?
IMO a USDC/USDP/GUSD metapool would be a valuable addition - gives an option for risk averse LPs who don’t want tether exposure. Decentralized stablecoins could pair with this pool to have reliable linkage to fiat, while minimizing tail risk (eg from Tether or DAI insolvency risk in current 3pool).
Also think this would help lift up GUSD and USDP/PAX (both high quality stablecoins but with limited adoption), which benefits Curve strategically in the long run - a greater diversity and more even balance of stablecoin market share should lead to higher stableswap volumes.
What are the benefits having a 2Pool ( USDC/USDT) and also having a 4Pool ?
I understand that MakerDao did not incentive veCRV but did we get any incentives of USDT or USDC ? Dai in my opinion is an OG in crypto and most tested protocol they did well at black swan event and back then MIM, Frax, Ust … wasn’t even exiting.
Here’s the rough lay of the land, as I see it:
- USDT and USDC are centralized.
- DAI is the #5 stablecoin, after BUSD and UST and the #2 decentralized stablecoin.
- A large part of the collateral backing DAI is USDC, which makes DAI an only partially decentralized stablecoin.
- UST is about 6x the size of Frax.
- There are definitely other worthy stablecoins.
The questions that I think the community needs to ask itself are:
- to what extent do we value neutrality vs decentralization?
- If a USDT/USDC base 2Pool would promote centralization, what would promote decentralization?
- what configuration would create the most robust liquidity, however that’s defined?
This quickly becomes a existential question about whether or not Curve is intended to be a legit defi/decentralized system or just a facade for fiat. I’m definitely in the true-defi camp (although it bugs me that DAI now has non-defi assets). At what point do we determine whether we are investing long term in honest money or still captured by money being inflated away at will by people who do not have our best interests in mind.
