I would be happy to write a proposal up. Before this though, given what Andre said on the previous proposal (YIP 42: Add RenBTC to yVaults), it seems prudent to address the concerns that were lifted and improve it as best as we can, instead of just submitting an identical proposal, which seems a bit spammy.
What are you envisioning @andre.cronje when you say ‘the best integration path for renBTC’? Of course Ren is working with many partners to bring more BTC into the DeFi ecosystem, which could give rise to a few different vault strategies for (ren)BTC. Until that matures though the Curve ren pool does seem viable for a vault, it is nothing fancy but it would seem to give consistently higher APY for BTC than the other vault for BTC that currently exists.
