Lockup

Abstract

Lockup module provides an interface for users to lock tokens (also known as bonding) into the module to get incentives.

After tokens have been added to a specific pool and turned into LP shares through the GAMM module, users can then lock these LP shares with a specific duration in order to begin earing rewards.

To unlock these LP shares, users must trigger the unlock timer and wait for the unlock period that was set initially to be completed. After the unlock period is over, users can turn LP shares back into their respective share of tokens.

This module provides interfaces for other modules to iterate the locks efficiently and grpc query to check the status of locked coins.

Concepts

The purpose of lockup module is to provide the functionality to lock tokens for specific period of time for LP token stakers to get incentives.

To unlock these LP shares, users must trigger the unlock timer and wait for the unlock period that was set initially to be completed. After the unlock period is over, users can turn LP shares back into their respective share of tokens.

This module provides interfaces for other modules to iterate the locks efficiently and grpc query to check the status of locked coins.

There are currently three incentivize lockup periods; 1 day (24h), 1 week (168h), and 2 weeks (336h). When locking tokens in the 2 week period, the liquidity provider is effectively earning rewards for a combination of the 1 day, 1 week, and 2 week bonding periods.

The 2 week period refers to how long it takes to unbond the LP shares. The liquidity provider can keep their LP shares bonded to the 2 week lockup period indefinitely. Unbonding is only required when the liquidity provider desires access to the underlying assets.

If the liquidity provider begins the unbonding process for their 2 week bonded LP shares, they will earn rewards for all three bonding periods during the first day of unbonding.

After the first day passes, they will only receive rewards for the 1 day and 1 week lockup periods. After seven days pass, they will only receive the 1 day rewards until the 2 weeks is complete and their LP shares are unlocked. The below chart is a visual example of what was just explained.

State

Locked coins management

Locked coins are all stored in module account for lockup module which is called LockPool. When user lock coins within lockup module, it's moved from user account to LockPool and a record (PeriodLock struct) is created.

Once the period is over, user can withdraw it at anytime from LockPool. User can withdraw by PeriodLock ID or withdraw all UnlockableCoins at a time.

Period Lock

A PeriodLock is a single unit of lock by period. It's a record of locked coin at a specific time. It stores owner, duration, unlock time and the amount of coins locked.

type PeriodLock struct {
  ID         uint64
  Owner      sdk.AccAddress
  Duration   time.Duration
  UnlockTime time.Time
  Coins      sdk.Coins
}

All locks are stored on the KVStore as value at {KeyPrefixPeriodLock}{ID} key.

Period lock reference queues

To provide time efficient queries, several reference queues are managed by denom, unlock time, and duration. There are two big queues to store the lock references. (a_prefix_key)

1. Lock references that hasn't started with unlocking yet has prefix of KeyPrefixNotUnlocking.
2. Lock references that has started unlocking already has prefix of KeyPrefixUnlocking.
3. Lock references that has withdrawn, it's removed from the store.

Regardless the lock has started unlocking or not, it stores below references. (b_prefix_key)

1. {KeyPrefixLockDuration}{Duration}
2. {KeyPrefixAccountLockDuration}{Owner}{Duration}
3. {KeyPrefixDenomLockDuration}{Denom}{Duration}
4. {KeyPrefixAccountDenomLockDuration}{Owner}{Denom}{Duration}

If the lock is unlocking, it also stores the below referneces.

1. {KeyPrefixLockTimestamp}{LockEndTime}
2. {KeyPrefixAccountLockTimestamp}{Owner}{LockEndTime}
3. {KeyPrefixDenomLockTimestamp}{Denom}{LockEndTime}
4. {KeyPrefixAccountDenomLockTimestamp}{Owner}{Denom}{LockEndTime}

For end time keys, they are converted to sortable string by using sdk.FormatTimeBytes function.

Note: Additionally, for locks that hasn't started unlocking yet, it stores accumulation store for efficient rewards distribution mechanism.

For reference management, addLockRefByKey function is used a lot. Here key is the prefix key to be used for iteration. It is combination of two prefix keys.({a_prefix_key}{b_prefix_key})

// addLockRefByKey make a lockID iterable with the prefix `key`
func (k Keeper) addLockRefByKey(ctx sdk.Context, key []byte, lockID uint64) error {
 store := ctx.KVStore(k.storeKey)
 lockIDBz := sdk.Uint64ToBigEndian(lockID)
 endKey := combineKeys(key, lockIDBz)
 if store.Has(endKey) {
  return fmt.Errorf("lock with same ID exist: %d", lockID)
 }
 store.Set(endKey, lockIDBz)
 return nil
}

Synthetic Lockup

Synthetic Lockups are a concept that serve the following roles:

• Add "restrictions" to an underlying PeriodLock, so that its bond status must be managed by a module rather than a BeginUnlockMessage
• Allow issuing of a locked, "synthetic" denom type
• Allow distribution of rewards to locked synthetic denominations.

The first goal can eventually be pushed into a new data structure, as it doesn't really relate to the synthetic component.

This is then used for superfluid staking. (Old docs below):

The goal of synthetic lockup is to support the querying of locks by denom especially for delegated staking. By combining native denom and synthetic suffix, lockup supports querying with synthetic denom with existing denom querying functions.

Synthetic lockup is creating virtual lockup where new denom is combination of original denom and synthetic suffix. At the time of synthetic lockup creation and deletion, accumulation store is also being updated and on querier side, they can query as freely as native lockup.

Note: The staking, distribution, slashing, superfluid module would be refactored to use lockup module and synthetic lockup. The following changes for synthetic lockup on native lockup change could be defined as per use case. For now we assume this change is made on hook receiver side which manages synthetic lockup, e.g. use cases are when user start / pause superfluid staking on a lockup, redelegation event, unbonding event etc.

External modules are managing synthetic locks to use it on their own logic implementation. (e.g. delegated staking and superfluid staking)

A SyntheticLock is a single unit of synthetic lockup. Each synthetic lockup has reference PeriodLock ID, synthetic suffix (Suffix) and synthetic lock's removal time (EndTime).

type SyntheticLock struct {
 LockId  uint64
 Suffix  string
 EndTime time.Time
}

All synthetic locks are stored on the KVStore as value at {KeyPrefixPeriodLock}{LockID}{Suffix} key.

Synthetic lock reference queues

To provide time efficient queries, several reference queues are managed by denom, unlock time, and duration.

1. {KeyPrefixDenomLockTimestamp}{SyntheticDenom}{LockEndTime}
2. {KeyPrefixDenomLockDuration}{SyntheticDenom}{Duration}
3. {KeyPrefixAccountDenomLockTimestamp}{Owner}{SyntheticDenom}{LockEndTime}
4. {KeyPrefixAccountDenomLockDuration}{Owner}{SyntheticDenom}{Duration}

SyntheticDenom is expressed as {Denom}{Suffix}. (Note: we can change this to {Prefix}{Denom} as per discussion with Dev)

For end time keys, they are converted to sortable string by using sdk.FormatTimeBytes function.

Note: To implement the auto removal of synthetic lockups that is already finished, we manage a separate time basis queue at {KeyPrefixSyntheticLockTimestamp}{EndTime}{LockId}{Suffix}

Messages

Lock Tokens

MsgLockTokens can be submitted by any token holder via a MsgLockTokens transaction.

type MsgLockTokens struct {
 Owner    sdk.AccAddress
 Duration time.Duration
 Coins    sdk.Coins
}

State modifications:

• Validate Owner has enough tokens
• Generate new PeriodLock record
• Save the record inside the keeper's time basis unlock queue
• Transfer the tokens from the Owner to lockup ModuleAccount.

Begin Unlock of all locks

Once time is over, users can withdraw unlocked coins from lockup ModuleAccount.

type MsgBeginUnlockingAll struct {
 Owner string
}

State modifications:

• Fetch all unlockable PeriodLocks that has not started unlocking yet
• Set PeriodLock's unlock time
• Remove lock references from NotUnlocking queue
• Add lock references to Unlocking queue

Begin unlock for a lock

Once time is over, users can withdraw unlocked coins from lockup ModuleAccount.

type MsgBeginUnlocking struct {
 Owner string
 ID    uint64
}

State modifications:

• Check PeriodLock with ID specified by MsgBeginUnlocking is not started unlocking yet
• Set PeriodLock's unlock time
• Remove lock references from NotUnlocking queue
• Add lock references to Unlocking queue

Note: If another module needs past PeriodLock item, it can log the details themselves using the hooks.

Lock Admin Keeper

Lockup admin keeper provides god privilege functions to remove tokens from locks and create new locks.

// AdminKeeper defines a god priviledge keeper functions to remove tokens from locks and create new locks
// For the governance system of token pools, we want a "ragequit" feature
// So governance changes will take 1 week to go into effect
// During that time, people can choose to "ragequit" which means they would leave the original pool
// and form a new pool with the old parameters but if they still had 2 months of lockup left,
// their liquidity still needs to be 2 month lockup-ed, just in the new pool
// And we need to replace their pool1 LP tokens with pool2 LP tokens with the same lock duration and end time

type AdminKeeper interface {
    Keeper

    // this unlock previous lockID and create a new lock with newCoins with same duration and endtime
    Relock(sdk.Context, lockID uint64, newCoins sdk.Coins) error
    // this unlock without time check with an admin priviledge
    BreakLock(sdk.Context, lockID uint64) error
}

Hooks

In this section we describe the "hooks" that lockup module provide for other modules.

Tokens Locked

On lock/unlock events, lockup module execute hooks for other modules to make following actions.

  OnTokenLocked(ctx sdk.Context, address sdk.AccAddress, lockID uint64, amount sdk.Coins, lockDuration time.Duration, unlockTime time.Time)
  OnTokenUnlocked(ctx sdk.Context, address sdk.AccAddress, lockID uint64, amount sdk.Coins, lockDuration time.Duration, unlockTime time.Time)

Parameters

The lockup module contains the following parameters:

Key	Type	Example

Note: Currently no parameters are set for lockup module, we will need to move lockable durations from incentives module to lockup module.

Endblocker

Withdraw tokens after unlock time mature

Once time is over, endblocker withdraw coins from matured locks and coins are sent from lockup ModuleAccount.

State modifications:

• Fetch all unlockable PeriodLocks that Owner has not withdrawn yet
• Remove PeriodLock records from the state
• Transfer the tokens from lockup ModuleAccount to the MsgUnlockTokens.Owner.

Remove synthetic locks after removal time mature

For synthetic lockups, no coin movement is made, but lockup record and reference queues are removed.

State modifications:

• Fetch all synthetic lockups that is matured
• Remove SyntheticLock records from the state along with reference queues

account-locked-beforetime

Query an account's unlocked records after a specified time (UNIX) has passed

In other words, if an account unlocked all their bonded tokens the moment the query was executed, only the locks that would have completed their bond time requirement by the time the TIMESTAMP is reached will be returned.

::: details Example

In this example, the current UNIX time is 1639776682, 2 days from now is approx 1639971082, and 15 days from now is approx 1641094282.

An account's ADDRESS is locked in both the 1 day and 1 week gamm/pool/3. To query the ADDRESS with a timestamp 2 days from now 1639971082:

merlind query lockup account-locked-beforetime ADDRESS 1639971082

In this example will output the 1 day lock but not the 1 week lock:

If querying the same ADDRESS with a timestamp 15 days from now 1641094282:

merlind query lockup account-locked-beforetime ADDRESS 1641094282

In this example will output both the 1 day and 1 week lock:

Here is an example of an account that is locked in both the 1 day and 1 week gamm/pool/3. In this example, the UNIX time is currently 1639776682 and queries an ADDRESS for UNIX time two days later from the current time (which in this example would be 1639971082)

merlind query lockup account-locked-pasttime mer1xqhlshlhs5g0acqgrkafdemvf5kz4pp4c2x259 1639971082

The example output:

locks:
- ID: "572027"
  coins:
  - amount: "16120691802759484268"
    denom: gamm/pool/3
  duration: 604800.000006193s
  end_time: "0001-01-01T00:00:00Z"
  owner: mer1xqhlshlhs5g0acqgrkafdemvf5kz4pp4c2x259

Note that the 1 day lock ID did not display because, if the unbonding time began counting down from the time the command was executed, the bonding period would be complete before the two day window given by the UNIX timestamp input. :::

account-locked-pasttime-denom

Query the locked records of an account with the unlock time beyond timestamp (unix) and filter by a specific denom

merlind query lockup account-locked-pasttime-denom mer1xqhlshlhs5g0acqgrkafdemvf5kz4pp4c2x259 [timestamp] [denom]

::: details Example

Here is an example of an account that is locked in both the 1 day and 1 week gamm/pool/3 and 1 day and 1 week gamm/pool/1. In this example, the UNIX time is currently 1639776682 and queries an ADDRESS for UNIX time two days later from the current time (which in this example would be 1639971082) and filters for gamm/pool/3

merlind query lockup account-locked-pasttime-denom mer1xqhlshlhs5g0acqgrkafdemvf5kz4pp4c2x259 1639971082 gamm/pool/3

The example output:

locks:
- ID: "572027"
  coins:
  - amount: "16120691802759484268"
    denom: gamm/pool/3
  duration: 604800.000006193s
  end_time: "0001-01-01T00:00:00Z"
  owner: mer1xqhlshlhs5g0acqgrkafdemvf5kz4pp4c2x259

Note that the 1 day lock ID did not display because, if the unbonding time began counting down from the time the command was executed, the bonding period would be complete before the two day window given by the UNIX timestamp input. Additionally, neither of the 1 day or 1 week lock IDs for gamm/pool/1 showed due to the denom filter. :::

account-locked-pasttime-not-unlocking

Query the locked records of an account with the unlock time beyond timestamp (unix) AND is not in the process of unlocking

merlind query lockup account-locked-pasttime [address] [timestamp]

::: details Example

Here is an example of an account that is locked in both the 1 day and 1 week gamm/pool/3. In this example, the UNIX time is currently 1639776682 and queries an ADDRESS for UNIX time two days later from the current time (which in this example would be 1639971082) AND is not unlocking:

merlind query lockup account-locked-pasttime mer1xqhlshlhs5g0acqgrkafdemvf5kz4pp4c2x259 1639971082

The example output:

locks:
- ID: "572027"

  end_time: "0001-01-01T00:00:00Z"
  owner: mer1xqhlshlhs5g0acqgrkafdemvf5kz4pp4c2x259

Note that the 1 day lock ID did not display because, if the unbonding time began counting down from the time the command was executed, the bonding period would be complete before the two day window given by the UNIX timestamp input. Additionally, if ID 572027 were to begin the unlocking process, the query would have returned blank. :::

account-unlockable-coins

Query an address's LP shares that have completed the unlocking period and are ready to be withdrawn

merlind query lockup account-unlockable-coins ADDRESS

account-unlocking-coins

Query an address's LP shares that are currently unlocking

::: details Example

merlind query lockup account-unlocking-coins mer1xqhlshlhs5g0acqgrkafdemvf5kz4pp4c2x259

Example output:

coins:
- amount: "15527546134174465309"
  denom: gamm/pool/3

:::

lock-by-id

Query a lock record by its ID

merlind query lockup lock-by-id [id]

::: details Example

Every time a user bonds tokens to an LP, a unique lock ID is created for that transaction.

Here is an example viewing the lock record for ID 9:

merlind query lockup lock-by-id 9

And its output:

lock:
  ID: "9"
  coins:
  - amount: "2449472670508255020346507"
    denom: gamm/pool/2
  duration: 336h
  end_time: "0001-01-01T00:00:00Z"
  owner: mer16r39ghhwqjcwxa8q3yswlz8jhzldygy66vlm82

In summary, this shows wallet mer16r39ghhwqjcwxa8q3yswlz8jhzldygy66vlm82 bonded 2449472.670 gamm/pool/2 LP shares for a 2 week locking period. :::
