constructor

constructor(contract IConditionalTokens _conditionalTokens, contract IWrapped1155Factory _wrapped1155Factory) public

​

splitFromDai

function splitFromDai(contract Market market, uint256 amount) external

1. The ERC20 associated to each outcome must be previously created on the wrapped1155Factory.

1. Transfer DAI from the user to MainnetRouter, which will be converted to Savings DAI (sDAI).
2. Call conditionalTokens.splitPosition to transfer sDAI fromMainnetRouter to ConditionalTokens, while minting corresponding ERC1155 outcome tokens to MainnetRouter.
3. Transfer ERC1155 outcome tokens from MainnetRouter to Wrapped1155Factory contract. There is a callback function in Wrapped1155Factory that will wrap the tokens into ERC20 tokens, then transfer the wrapped tokens back to the original user.

​

mergeToDai

function mergeToDai(contract Market market, uint256 amount) external

1. The ERC20 associated to each outcome must be previously created on the wrapped1155Factory.
2. The caller must have <amount> ERC20 tokens of all the outcomes of a market. For example, to call mergeToDai of a market with 3 outcomes: Yes, No, Invalid, the caller must have <amount> tokens for each outcome.

1. Unwraps ERC20 outcome tokens (which will burn these tokens and transfer corresponding ERC1155 outcome tokens tokens back to the Router contract).
2. Call conditionalTokens.mergePositions to burn ERC1155 outcome tokens.
3. Return sDAI to MainnetRouter , which will then be converted to DAI and sent to the user.

​

redeemToDai

function redeemToDai(contract Market market, uint256[] outcomeIndexes, uint256[] amounts) external

1. The ERC20 associated to each outcome must be previously created on the wrapped1155Factory.
2. The caller must have ERC20 tokens of the outcomes they want to redeem. For example, to call redeemToDai for outcome Yes of a market with 3 outcomes: Yes, No, Invalid, the caller must have Yes tokens. (The call will still be processed even if the caller does not have tokens, but it will have no effect).
3. conditionalTokens.reportPayouts has been called by an oracle.

1. Unwraps ERC20 outcome tokens (which will burn these tokens and transfer corresponding ERC1155 outcome tokens back to the MainnetRouter contract).
2. Call conditionalTokens.redeemPositions to burn ERC1155 outcome tokens.
3. Return sDAI to MainnetRouter . MainnetRouter will calculate the sDAI difference before and after redeeming, which will then be converted to DAI and sent to the user.
