Market Metadata

The Unitroller contract has an array called allMarkets that contains the addresses of each fToken contract. Each address in the allMarkets array can be used to fetch a metadata struct in the Unitroller’s markets constant.

fToken[] public allMarkets;

Solidity

Unitroller troll = Unitroller(0xABCD...);
fToken fTokens[] = troll.allMarkets();
