Terraswap Router

The Router Contract contains the logic to facilitate multi-hop swap operations among the liquidity pools.

Imagine there are three tokens, A B and C. Say a bot wants to swap A for C, but only two pools are available, A-B and B-C. Thus, the router can be used to swap A for B and then B for C.

The router can handle both native and cw20 tokens, provided the corresponding AssetInfo:

pub enum AssetInfo {
    Token { contract_addr: String },
    NativeToken { denom: String },
}

Example

Swap A => B => C
