Substrate Asset Conversion pallet

Substrate Asset Conversion pallet based on the Uniswap V2 logic.

Overview

This pallet allows you to:

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].

(For an example of configuring this pallet to use MultiLocation as an asset id, see the cumulus repo).

Here is an example state_call that asks for a quote of a pool of native versus asset 1:

curl -sS -H "Content-Type: application/json" -d \
'{"id":1, "jsonrpc":"2.0", "method": "state_call", "params": ["AssetConversionApi_quote_price_tokens_for_exact_tokens", "0x0101000000000000000000000011000000000000000000"]}' \

(This can be run against the kitchen sync node in the node folder of this repo.)

Re-exports

Modules

  • The pallet module in each FRAME pallet hosts the most important items needed to construct this pallet.
  • Autogenerated weights for pallet_asset_conversion

Macros

  • Enable/disable the given code depending on feature = "runtime-benchmarks" being enabled for the crate or not.

Structs

  • Converts between a MultiAssetId and an AssetId (or the native currency).
  • Stores the lp_token asset id a particular pool has been assigned.

Enums

Traits

  • This runtime api allows people to query the size of the liquidity pools and quote prices for swaps.
  • Benchmark Helper
  • A trait that converts between a MultiAssetId and either the native currency or an AssetId.
  • Trait for providing methods to swap between the various asset classes.
