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...);
SToken[] memory aTokens = new SToken[](2);
aTokens[0] = SErc20(0x3FDA...);
aTokens[1] = SEther(0x3FDB...);
uint[] memory errors = troll.enterMarkets(aTokens);

const troll = Comptroller.at(0xABCD...);
const aTokens = [SErc20.at(0x3FDA...), SEther.at(0x3FDB...)];
const errors = await troll.methods.enterMarkets(aTokens).send({from: ...});
