Every YSL, xYSL, bYSL, USDy, xBUSD and BSHARE token that ever exists is caused to exist by a user creating it by themselves as per the rules of the code that they choose to run. This code lives at a BNB Chain contract address and might be referred to as YSL.IO. Users mine their own block or pay a miner to do it for them. Only you can mint your own YSL, xYSL, bYSL, USDy, xBUSD and BSHARE tokens when you run the exchange function in the code, as it requires your private key. Only you can run the deposit function in the code to deposit tokens, as it requires your private key. Only you can run the withdraw function in the code to withdraw tokens, as it requires your private key. Only you can claim rewards when you run the claim function in the code, as it requires your private key.
