In what currency? As I understand it, Stablecoins are bound to an underlying currency. If you do not wan't to tie it to a currency, bitcoin would be the prime candidate. And with its layer 2 solutions such as Lightning, there is already a decentralized system for fast, cheap and private payments.

If this Tempo blockchain truly delivers, it'll not be that difficult for anyone to create a decentralized exchange using smart contracts and AMMs. And you can create a Wrapped BTC to use as well. Also gold-backed stablecoins.

Lightning is not a solution. Having to run a node that's online 24/7 is unreasonable, and so is having to convince others to allocate inbound liquidity to you. Any wallet which does not require this is heavily centralized and often custodial.

		> Lightning is not a solution. Having to run a node that's online 24/7 is unreasonable I agree, but with trampoline payments approaching standardization (it is in use by electrum and ACINQ/Phoenix wallet already) and async payments, the 24/7 issue should be gone. I DO agree that stablecoins are different and probably have a different setup - they are still centralized and require trust (that the underlying asset is held accordingly), while Bitcoin/L2-Lightning are completely decentralized.
