Summary

For the Sifchain MVP ,CLP module provides the following functionalities

  • Create New Liquidity Pool
  • Add Liquidity to an Existing Liquidity pool
  • Remove Liquidity from an Existing Liquidity pool
  • Swap tokens
    -Swap an External token for Native or vice versa (single swap)
    -Swap an External token for another External Token (double swap)
  • Decommission an Existing Liquidity pool
Data structures

-Asset : An asset is most basic unit of a CLP . It Contains source chain, symbol and ticker to identify a token .

SourceChain: ETHEREUM
Symbol: ETH
Ticker: ceth

SourceChain: SIFCHAIN
Symbol: RWN
Ticker: rwn

-Pool : Every Liquidity pool for CLP is created by pairing an External asset with the Native asset .

ExternalAsset: SourceChain: ETHEREUM
              Symbol: ETH
              Ticker: ceth
ExternalAssetBalance: 1000
NativeAssetBalance: 1000
PoolUnits : 1000
PoolAddress :sif1vdjxzumgtae8wmstpv9skzctpv9skzct72zwra

-Liquidity provider : Any user adding liquidity to a pool becomes a liquidity provider for that pool.

ExternalAsset: SourceChain: ETHEREUM
               Symbol: ETH
               Ticker: ceth
LiquidityProviderUnits: 1000
liquidityProviderAddress: sif15tyrwghfcjszj7sckxvqh0qpzprup9mhksmuzm

Trasactions supported

  • Create new liquidity pool

    • Creating a pool has a minimum threshold for the amount of liquidity provided. This is a genensis parameter and can be tweaked later.
    • The user who creates a new pool automatically becomes its first liquidity provider.

  • Decommission a liquidity pool

    • Decommission requires the net balance of the pool to be under the minimum threshold .
    • If successful a decommission transaction returns balances to its liquidity providers and deletes the liquidity pool.

  • Add Liquidity to a pool

    • User can add liquidity to the native and external tokens

  • Remove liquidity

    • Remove liquidity consists of a composition of withdraw , and a swap if required

    • Liquidity can be removed in three ways

      -Native and external - Withdraw to native and external tokens .
      -Only Native - Withdraw to native and external tokens ,and then a swap from external to native.
      -Only External - Withdraw to native and external tokens ,and then a swap from native to external.

    • For asymmetric removal , (option 2 and 3), the user incurs a tradeslip and liquidity fee similar to a swap.

  • Swap

    • The system supports two types of swaps
      -Swap between external and native tokens - This is a single swap
      -Swap between external and external tokens - This swap is combination of two single swaps.

    • A double swap also includes a transfer between the two pools to maintain pool balances.
