iSynths inversely track the price of assets via price feeds supplied by either Synthetix's oracle or Chainlink's oracle network of distributed node operators. They allow traders to effectively take a short position, and are currently available for Crypto Synths and Index Synths. Each iSynth has three important points: an entry point, an upper limit, and a lower limit. Its entry point is the price at which it is entered into the system. Inversely tracks the price of Inverse DeFi Index (DEFI) through price feeds supplied by an oracle. The entry point is $2714.42 (the approximate market price at time of creation). This Synth freezes when it reaches its upper limit of $4071.63 (i.e. when Inverse DeFi Index's value reaches $1357.21) or its lower limit of $1357.21 (i.e. when Inverse DeFi Index’s value reaches $4071.63). If it reaches either of its limits and gets frozen, it will no longer be able to be purchased on Synthetix.Exchange, but can still be traded for other Synths at its frozen value. At some point after it has reached either of its limits, it will be substituted for another iDEFI with different limits.
