The plan for those is also essentially the same as what I described above, to continue incentives that promote liquidity on Curve, particularly to attract crvUSD migration to Arbitrum.
To elaborate a little more on the current blocker, the stableswap implementation on Arbitrum has a min fee of .04%. It needs a redeployment to support the crvUSD use case which will have a .01% fee. We’re waiting for the stableswap-ng factory which is in audit and you can follow fixes from auditor comments here. The dev working on it says Arbitrum will have the factory deployed in around 2 weeks time.
As for tricrypto, Curve team has been monitoring the performance of various tricrypto configs to determine the best path forward with the Arbitrum deployment. The crvUSD/tBTC/ETH pool on Base is being considered as the model to go off and team will be running some sims for parameter optimizations.
So basically, these are pretty minimal blockers and pool incentives should be ready to start flowing quite quickly.
