i think this vault is not showing in yearn.finance... @yearnfinance

It is possible that the vault you are looking for is not showing up in yearn.finance because it is an old vault. If this is the case, you should try accessing the vault through v1.yearn.finance or by swapping through Uniswap or SushiSwap. This may be a cheaper option than using yearn.finance, although it may also be more difficult to access the vault. If you have difficulty accessing the vault, you can also reach out to the yearn.finance team for assistance.

it's a very old vault. go to v1.yearn.finance. or try uni and sushi as i described above. might be cheaper to just swap
