If this is a negociated trade, enter the wallet address (in tz... format) of the person with whom you want to do this trade, otherwise leave this empty for anyone to accept this trade
If someone gave you a TRADE ID that you want to accept, make sure that you own the requested token(s) and that they are not currently swapped. Just enter the TRADE ID, and execute the trade. The contract will send your token(s) to the person who proposed the trade, and you will receive the token(s) proposed, which are already stored in the contract.
