pallet-asset-conversion : Support for Multi-Asset Conversion

[muddlebee]

Is there an existing issue?

• I have searched the existing issues

Experiencing problems? Have you tried our Stack Exchange first?

• This is not a support question.

Motivation

Currently, swapping assets across separate pools requires multiple transactions. Like for USDC -> WETH, we have to

Swap 1: USDC → DOT (Pool A)
Swap 2: DOT → WETH (Pool B)

Request

Enable multi-asset swaps within a single transaction in pallet-asset-conversion to improve efficiency and reduce fees.

Solution

No response

Are you willing to help with this request?

Maybe (please elaborate above)

Isn't this already supported?

//! The `quote_price_exact_tokens_for_tokens` and `quote_price_tokens_for_exact_tokens` functions
//! both take a path parameter of the route to take. If you want to swap from native asset to
//! non-native asset 1, you would pass in a path of `[DOT, 1]` or `[1, DOT]`. If you want to swap
//! from non-native asset 1 to non-native asset 2, you would pass in a path of `[1, DOT, 2]`.

@bkontur thank you it works 🙏 we just have to provide multiple paths[ ] instead of just tokenA -> tokenB
some clarification made in this PR #7951
