Router implementation with functions to interact with xDAI on Gnosis Chain.

​
Variables

​
sDAI

sDAI address.

​
savingsXDaiAdapter

SavingsXDaiAdapter address.

​
Functions

​
constructor

Constructor. Parameters

​
splitFromBase

Splits a position using xDAI and sends the ERC20 outcome tokens back to the user. The ERC20 associated to each outcome must be previously created on the wrapped1155Factory. Parameters Pre-condition
  1. The ERC20 associated to each outcome must be previously created on the wrapped1155Factory.
Logic
  1. The user send native tokens (xDAI), which will be converted to Savings xDAI (sDAI) and transferred to GnosisRouter.
  2. Call conditionalTokens.splitPosition to transfer sDAI from GnosisRouter to ConditionalTokens, while minting corresponding ERC1155 outcome tokens to GnosisRouter.
  3. Transfer ERC1155 outcome tokens from GnosisRouter 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.

​
mergeToBase

Merges positions and sends xDAI to the user. The ERC20 associated to each outcome must be previously created on the wrapped1155Factory. Parameters Pre-condition
  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 mergeToBase of a market with 3 outcomes: Yes, No, Invalid, the caller must have <amount> tokens for each outcome.
Logic Merging positions does precisely the opposite of what splitting a position does.
  1. Unwraps ERC20 outcome tokens (which will burn these tokens and transfer corresponding ERC1155 outcome tokens back to the GnosisRouter contract).
  2. Call conditionalTokens.mergePositions to burn ERC1155 outcome tokens.
  3. Return sDAI to GnosisRouter, which will then be converted to xDAI and sent to the user.

​
redeemToBase

Redeems positions and sends xDAI to the user. The ERC20 associated to each outcome must be previously created on the wrapped1155Factory. Parameters Pre-condition
  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 redeemToBase 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.
Logic
  1. Unwraps ERC20 outcome tokens (which will burn these tokens and transfer corresponding ERC1155 outcome tokens back to the GnosisRouter contract).
  2. Call conditionalTokens.redeemPositions to burn ERC1155 outcome tokens.
  3. Return sDAI to GnosisRouter . GnosisRouter will calculate the sDAI difference before and after redeeming, which will then be converted to xDAI and sent to the user.
