Transfers multiple conditional outcome ERC-1155 tokens from one account to another in a single call.✨ AI

开发者： Transfers `values` amount(s) of `ids` from the `from` address to the `to` address specified. Caller must be approved to manage the tokens being transferred out of the `from` account. If `to` is a smart contract, will call `onERC1155BatchReceived` on `to` and act appropriately.

参数

Split a collateral position into outcome tokens for a specified condition partition.✨ AI

开发者： This function splits a position. If splitting from the collateral, this contract will attempt to transfer `amount` collateral from the message sender to itself. Otherwise, this contract will burn `amount` stake held by the message sender in the position being split worth of EIP 1155 tokens. Regardless, if successful, `amount` stake will be minted in the split target positions. If any of the transfers, mints, or burns fail, the transaction will revert. The transaction will also revert if the given partition is trivial, invalid, or refers to more slots than the condition is prepared with.
