Finally stableswap pools are working the way they should. Previously, liquidity pools that held coins with linearly dependent prices like TON/USDT or ETH/WETH still needed to provide liquidity in a 50/50 ratio, even though there was no real need to do so. Now, on the main DEX of the $TON blockchain - STON.fi, this misunderstanding has been corrected, and the tsTON/TON pool can now provide liquidity in any ratio, and the technology does not involve pre-swap via smart contracts.

But in general, the same feature is available in any regular liquidity pool on STON.fi, it just works differently, and the feature is just provided for convenience - Arbitrary Provision. It just works in any pair, and just pre-executes the swap so that the coins are in the price equivalent. Overall it's much more convenient.
