// Deposit creates a new pool or adds liquidity to an existing pool. For a pool to be created, a pool
// for the coin denominations must not exist yet, and it must be allowed by the swap module parameters.
//
// When adding liquidity to an existing pool, the provided coins are considered to be the desired deposit
// amount, and the actual deposited coins may be less than or equal to the provided coins. A deposit
// will never be exceed the coinA and coinB amounts.
//
// The slippage is calculated using both the price and inverse price of the provided coinA and coinB.
// Since adding liquidity is not directional, like a swap would be, using both the price (coinB/coinA),
// and the inverse price (coinA/coinB), protects the depositor from a large deviation in their deposit.
//
// The amount deposited may only change by B' < B or A' < A -- either B depreciates, or A depreciates.
// Therefore, slippage can be written as a function of this depreciation d. Where the new price is
// B*(1-d)/A or A*(1-d)/B, and the inverse of each, and is A/(B*(1-d)) and B/(A*(1-d))
// respectively.
//
// Since 1/(1-d) >= (1-d) for d <= 1, the maximum slippage is always in the appreciating price
// A/(B*(1-d)) and B/(A*(1-d)). In other words, when the price of an asset depreciates, the
// inverse price -- or the price of the other pool asset, appreciates by a larger amount.
// It's this percent change we calculate and compare to the slippage limit provided.
//
// For example, if we have a pool with 100e6 ukava and 400e6 usdx. The ukava price is 4 usdx and the
// usdx price is 0.25 ukava. If a depositor adds liquidity of 4e6 ukava and 14e6 usdx, a kava price of
// 3.50 usdx and a usdx price of 0.29 ukava. This is a -12.5% slippage is the ukava price, and a 14.3%
// slippage in the usdx price.
//
// These slippages can be calculated by S_B = ((A/B')/(A/B) - 1) and S_A ((B/A')/(B/A) - 1), simplifying to
// S_B = (A/A' - 1), and S_B = (B/B' - 1). An error is returned when max(S_A, S_B) > slippageLimit.

This is implemented in handler with a interface to easily apply to it to all messages, and separate msg validation concerns from the keeper * move allowed pools to params -- let pool and pool_test focus on pool domain logic, not parameter & governance concerns * update alias * add unitless implementatin of constant product liquidity pool to isolate and enapsulate liquidity logic. Swap methods interfaces are added, but implementation not yet added * nits and todos * add ErrInvalidPool * add tests for edge cases around pool depletion; add explicit panic for edge case that results in a pool reserve being zero; handle pool reinitialization if it is empty * touch up comments and flush out the rest of assertions * add data structures for keeper state storage separate from pool domain objects, and improve structure for easier querying * rename pool name to pool key for events * add support for a denominated pool that uses sdk.Coins and sdk.Coin arguments, keeping tracking of the units in the base pool. This gives nice separation between pool logic, and coin/denom logic * refactor keeper to use new records for storage, and implement pool deposit using the denominated pool * address previous PR comment - reminder for migration if changing account permissions * msg deposit should validate that denoms are not equal * add godoc comments * golint and some poolName -> poolID cleanup * implement adding liquidity to an existing pool * hardcode pools in sims * touch up comment * withdraw keeper logic * withdraw type updates * add withdraw msg tx handler * initial withdraw test * fix panic * use new denominated pool with existing shares * fix: check args on deposit cmd * add slippage limit check for depositing to an existing pool * send coins just before event emission * check liquidity returned is greater than zero for both coins; ensure returned number of shares are greater than zero * add deadline to msgwithdraw * register msgwithdraw * scaffold msgwithdraw types test * register the correct msg * modify swap functions to also return the amount paid for the pool swap fee. This will be used to calculate slippage and for event tracking * add slippage types * add expected withdrawal coins * calculate slippage against expected coins * update withdraw keeper tests * spelling, improve comments on add liquidity math * typo * typo * grammer * typo / grammer * remove pool_id from withdraw msg * add slippage to tx cmd * TestWithdraw_Partial * nit * add withdraw no pool, no deposit record tests * drop event check on partial withdraw test * fix broken link * fix broken link * resolve merge conflicts * ensure swap fee can not be equal to 1; add full implementation of swap pool methods; these implementation ensure that the pool invariant is always greater or equal to the previous invariant * refactor duplicated code into private swap methods * add runtime assertion to always ensure invariant is greater or equal to the previous invariant sub fee on swaps * improve comments for base pool swap functions * add swap exact input and output methods to denominated pool that wrap the base pool interface for swapping * comment touch ups * more comment touchups * fix msg deposit struct tag (#943) * use better name for swap calculation private methods * nits: golint * fix misspelling in method name * Add HARD token governance committee for Hard module (#941) * add hard gov token committee * revisions: update migration * revisions: update test/data file * initial revisions * add TokenCommittee JSONMarshal test * fix SetPermissions method * remove BaseCommittee Type field * add incentive params to allowed params * Add SWP token governance committee for Swap module (#946) * add swp token commitee to migration * update test, add gen export utility method * final revisions: add TODO * remove slippage from withdraw to use min values for coins; add additional validation test cases * update alias for swap module * add withdraw tests to handler for increased coverage; note: first pass, improvements still yet to be made here * refact withdraw keeper to use min amounts; panic for cases that do not happen in normal situations * lint fixes * use total shares to track if pool should be deleted; add more in depth withdraw comment * add exact args for withdraw cmd * extract record update methods * update depositor share record if it exists -- do not overwrite an existing record; ensures no loss of shares if the same address deposits more than once * Swap queries: deposit, pool, pools (#949) * query deposits types * implement deposit querier keeper methods * query deposits CLI * query deposits REST * query types for pool/pools * pool/pools querier keeper methods * pool/pools CLI * pool/pools REST * basic pool/pools query tests * basic deposit querier test * iterate share records via owner bytes * nit: add example for querying deposits by owner only Co-authored-by: karzak <kjydavis3@gmail.com> * feat: add REST tx handler for swap LP withdrawals Co-authored-by: Nick DeLuca <nickdeluca08@gmail.com> Co-authored-by: Denali Marsh <denali@kava.io> Co-authored-by: denalimarsh <denalimarsh@gmail.com> Co-authored-by: karzak <kjydavis3@gmail.com>
