# Router Mechanism

Kriya router is a multi-protocol, multi-path router that leverages Sui's PTB (programmable txn blocks) to aggregate liquidity from all sources to execute trades and find the best price for traders.

These sources are - 

1. Kriya CLMM, AMM pools
2. Deepbook
3. Other protocols integrated via Hop and AF Routers

The GetRoute function uses the [Pyth](https://pyth.network/) Oracle to determine the deviation of each source from the benchmark. Sources with high deviation are excluded from the route.
