Question:

1. We use a CollateralWrapper (0x75d9e518f46a9ca0404fb0a7d386ce056dadf57fd9a0e8659772cb517be4a18) to wrap WBTC. The TVL is currently computed by checking the balanceOf the CollateralWrapper. In an ideal scenario, we would check the balanceOf (in CollateralWrapper) of our DefaultPool and ActivePool. But if we do this, we have no price because the CollateralWrapper is listed no where
2. WBTC (as currently set) outputs:

Where can I specify name symbol and decimals?

Who deployed the wrapper?

[pscott]

Who deployed the wrapper?

We did. It's still upgradeable, but we will renounce ownership.
Our protocol went live on Tuesday, so we are waiting to make sure everything is fine.

[waynebruce0x]

please remove this, we will just count the WBTC in the wrapper

[pscott]

fee103d

removed the api.addTokens line

[waynebruce0x]

so we should now just be returning a balance of WBTC_CONTRACT does that make sense?

[pscott]

for now returning the balance, in WBTC, of the WWBTC_CONTRACT would be enough

[waynebruce0x]

yeah but since youre using the wrapper address in your exported balances we have a TVL of zero since that asset isnt priced yet. Please use WBTC_CONTRACT

[pscott]

I had misunderstood your earlier comment. Fixed in e08044c
