Module IStablecoinDEX

Expand description

StablecoinDEX interface for managing orderbook based trading of stablecoins.

The StablecoinDEX provides a limit orderbook system where users can:

Place limit orders (buy/sell) with specific price ticks
Place flip orders that automatically create opposite-side orders when filled
Execute swaps against existing liquidity
Manage internal balances for trading

The exchange operates on pairs between base tokens and their designated quote tokens, using a tick-based pricing system for precise order matching.
