Enter Markets

Enter into a list of markets - it is not an error to enter the same market more than once. In order to supply collateral or borrow in a market, it must be entered first.

Comptroller

function enterMarkets(address[] calldata aTokens) returns (uint[] memory)

• msg.sender: The account which shall enter the given markets.

• aTokens: The addresses of the aToken markets to enter.

• RETURN: For each market, returns an error code indicating whether or not it was entered. Each is 0 on success, otherwise an Error code.

Solidity

Comptroller troll = Comptroller(0xABCD...);
AToken[] memory aTokens = new AToken[](2);
aTokens[0] = AErc20(0x3FDA...);
aTokens[1] = CEther(0x3FDB...);
uint[] memory errors = troll.enterMarkets(aTokens);
