description	This skill should be used when the user asks about Kriya DEX, Kriya AMM, Kriya CLMM, Kriya spot DEX, Kriya oracle-driven pools, or wants to integrate with Kriya on Sui. Covers AMM swaps, stable/uncorrelated pool liquidity management, and oracle-driven PMM trading.

Kriya DEX on Sui

Kriya is a DEX protocol on Sui with two main components:

1. Spot DEX (AMM) -- Classic AMM with both stable and uncorrelated pool types
2. Oracle-Driven Pools (PMM) -- Proactive Market Maker pools using Pyth oracle price feeds

Architecture

Spot DEX (AMM)

• Uncorrelated pools (is_stable: false): Constant-product (x*y=k)
• Stable pools (is_stable: true): Curve-style x*y*(x^2+y^2) = k
• Key types: Pool<T0, T1>, KriyaLPToken<T0, T1>, ProtocolConfigs
• Fee model: Uses 1,000,000 base (millionths)

Oracle-Driven Pools (PMM)

• Uses Pyth price oracle feeds for pricing
• Separate base and quote reserves with target amounts
• Key types: oracle_driven_pool::Pool<T0, T1>, BasePoolLiquidityCoin, QuotePoolLiquidityCoin

Common Patterns

AMM Swap

// Swap T0 for T1
let coin_out = spot_dex::swap_token_x<T0, T1>(
    pool, coin_in, amount_in, min_amount_out, ctx
);
// Swap T1 for T0
let coin_out = spot_dex::swap_token_y<T0, T1>(
    pool, coin_in, amount_in, min_amount_out, ctx
);

AMM Add/Remove Liquidity

let lp_token = spot_dex::add_liquidity<T0, T1>(
    pool, coin_y, coin_x, amount_x, amount_y, min_x, min_y, ctx
);
let (coin_y, coin_x) = spot_dex::remove_liquidity<T0, T1>(
    pool, lp_token, lsp_amount, ctx
);

Oracle-Driven Trading

// Sell base, receive quote (requires Pyth PriceInfoObjects)
let quote = trader::sell_base_coin<T0, T1>(
    pool, clock, base_price_info, quote_price_info, base_coin, amount, min_receive, ctx
);
// Buy base, pay quote
let base = trader::buy_base_coin<T0, T1>(
    pool, clock, base_price_info, quote_price_info, quote_coin, amount, max_pay, ctx
);

Read-Only Queries

let (reserve_y, reserve_x, lsp_supply) = spot_dex::get_reserves<T0, T1>(pool);
let mid_price = trader::get_mid_price<T0, T1>(pool, clock, base_price, quote_price);
