My understanding is that Sonic is going to start a new one, SNS-W, which will do for ICP what Synthetix is doing with SNX as collateral to create a variety of synthetic assets. Tokens that could not be handled before, such as stablecoin, can be achieved in the Sonic economy. Depending on how it is done, it may be possible to increase the utility of ckbtc, SNS-1, etc.
