Concepts

The x/gamm module implements an AMM using:

  • Balancer style pools with varying amounts and weights of assets in pools.
  • Stableswap pools have liquidity centered around a given spot price. See here for the spec of the Osmosis implementation.

Here we will explain basic GAMM concepts and give an overview of how GAMM module's code is organized to support both type of pools.

Pool
Creation of Pool

At an initial creation of the pool, a fixed amount of 100 share token is minted in the pool and sent to the creator of the pool's account. The pool share denom is in the format of gamm/pool/{poolID} and is displayed in the format of GAMM-{poolID} to the user. Pool assets are sorted in alphabetical order by default. Pool creation is possible only for at least 2 and no more than 8 denominations.

PoolCreationFee needs to be paid to create the pool. This also keeps us safe when it comes to the malicious creation of unneeded pools.

Joining Pool

When joining a pool without swapping - with JoinPool, a user can provide the maximum amount of tokens TokenInMaxs' they're willing to deposit. This argument must contain all the denominations from the pool or no tokens at all, otherwise, the tx will be aborted. If TokenInMaxs` contains no tokens, the calculations are done based on the user's balance as the only constraint.

The front end takes care of the calculation of how many share tokens the user is eligible for at the specific moment of sending the transaction.

Calculation of exactly how many tokens are needed to get the designated share is done at the moment of processing the transaction, validating that it does not exceed the maximum amount of tokens the user is willing to deposit. After the validation, GAMM share tokens of the pool are minted and sent to the user's account.

Joining the pool using a single asset is also possible with JoinSwapExternAmountIn.

Existing Join types:

  • JoinPool
  • JoinSwapExternAmountIn
  • JoinSwapShareAmountOut
Join types code call stack and structure:

Exiting Pool

When exiting a pool, the user provides the minimum amount of tokens they are willing to receive as they are returning their shares of the pool. However, unlike joining a pool, exiting a pool requires the user to pay the exit fee, which is set as a param of the pool. The user's share tokens burnt as result. Exiting the pool using a single asset is also possible.

Exiting a pool is possible only if user will leave a positive balance for a certain denomination after exiting or positive number of LP shares. Otherwise transaction will be aborted and user will not be able to exit a pool. Therefore, it is not possible to "drain out" a pool.

When exiting a pool with a swap, both exit and swap fees are paid.

Existing Exit types:

  • ExitPool
  • ExitSwapExternAmountOut
  • ExitSwapShareAmountIn
Exit types code call stack and structure:

Swap

During the process of swapping a specific asset, the token the user is putting into the pool is denoted as tokenIn, while the token that would be returned to the user, the asset that is being swapped for, after the swap is denoted as tokenOut throughout the module.

Given a tokenIn, the following calculations are done to calculate how many tokens are to be swapped into and removed from the pool:

tokenBalanceOut * [1 - { tokenBalanceIn / (tokenBalanceIn + (1 - swapFee) * tokenAmountIn)} ^ (tokenWeightIn / tokenWeightOut)]

The calculation is also able to be reversed, the case where user provides tokenOut. The calculation for the amount of tokens that the user should be putting in is done through the following formula:

tokenBalanceIn * [{tokenBalanceOut / (tokenBalanceOut - tokenAmountOut)} ^ (tokenWeightOut / tokenWeightIn) -1] / tokenAmountIn

Existing Swap types:

  • SwapExactAmountIn
  • SwapExactAmountOut
Spot Price

Meanwhile, calculation of the spot price with a swap fee is done using the following formula:

spotPrice / (1 - swapFee), where spotPrice is defined as:

(tokenBalanceIn / tokenWeightIn) / (tokenBalanceOut / tokenWeightOut)

Spot price

Multi-Hop

All tokens are swapped using a multi-hop mechanism. That is, all swaps are routed via the most cost-efficient way, swapping in and out from multiple pools in the process. The most cost-efficient route is determined offline and the list of the pools is provided externally, by user, during the broadcasting of the swapping transaction. In the moment of the execution the provided route may not be the most cost efficient one anymore.

When a trade consists of just two OSMO-included routes during a single transaction, the swap fees on each hop would be automatically halved. Example: for converting ATOM -> OSMO -> LUNA using two pools with swap fees 0.3% + 0.2%, instead 0.15% + 0.1% fees will be aplied.

Multi-Hop

Weights

Weights refer to the how we weight the reserves of assets within a pool. Its often convenient to think of weights in terms of ratios, so a 1:1 pool between "ATOM" and "BTC" is a pool where the spot price is #ATOM in pool / #BTC in pool.

A 2:1 pool is one where the spot price is 2*(#ATOM in pool) / #BTC in pool. This weights allows one to get the same spot price in the pool, with fewer ATOM reserves. (This comes at the cost of having higher slippage, e.g. buying 10 atoms moves the price more than a 1:1 pool with the same BTC liquidity).

Within the state machine, we represent weights as numbers, and the ratios are computed internally. So you could specify a pool between three assets, with weights 100:30:50, which is equivalent to a 10:3:5 pool.

The ratios provided in a CreatePool message, or governance proposal are capped at 2^20. However, within the state machine they are stored with an extra 30 bits of precision, allowing for smooth changes between two weights to happen with sufficient granularity.

(Note, these docs are intended to get shuffled around as we write more of the spec for x/gamm. I just wanted to document this along with the PR, to save work for our future selves)

Network Parameters

Pools have the following parameters:

Key Type
SwapFee sdk.Dec
ExitFee sdk.Dec
FutureGovernor *FutureGovernor
Weights *Weights
SmoothWeightChangeParams *SmoothWeightChangeParams
PoolCreationFee sdk.Coins
  1. SwapFee - The swap fee is the cut of all swaps that goes to the Liquidity Providers (LPs) for a pool. Suppose a pool has a swap fee s. Then if a user wants to swap T tokens in the pool, sT tokens go to the LP's, and then (1 - s)T tokens are swapped according to the AMM swap function.
  2. ExitFee - The exit fee is a fee that is applied to LP's that want to remove their liquidity from the pool. Suppose a pool has an exit fee e. If they currently have S LP shares, then when they remove their liquidity they get tokens worth (1 - e)S shares back. The remaining eS shares are then burned, and the tokens corresponding to these shares are kept as liquidity.
  3. FutureGovernor - Osmosis plans to allow every pool to act as a DAO, with its own governance in a future upgrade. To facilitate this transition, we allow pools to specify who the governor should be as a string. There are currently 3 options for the future governor.
    • No one will govern it. This is done by leaving the future governor string as blank.
    • Allow a given address to govern it. This is done by setting the future governor as a bech32 address.
    • Lockups to a token. This is the full DAO scenario. The future governor specifies a token denomination denom, and a lockup duration duration. This says that "all tokens of denomination denom that are locked up for duration or longer, have equal say in governance of this pool".
  4. Weights - This defines the weights of the pool - https://balancer.fi/whitepaper.pdf
  5. SmoothWeightChangeParams - This allows pool governance to smoothly change the weights of the assets it holds in the pool. So it can slowly move from a 2:1 ratio, to a 1:1 ratio. Currently, smooth weight changes are implemented as a linear change in weight ratios over a given duration of time. So weights changed from 4:1 to 2:2 over 2 days, then at day 1 of the change, the weights would be 3:1.5, and at day 2 its 2:2, and will remain at these weight ratios.

The GAMM module also has a PoolCreationFee parameter, which currently is set to 100000000 uosmo or 100 OSMO.
