- Infinity amount of wallets, no huge mapping
- High bandwidth, swap and wallet minimize count of swaps
- Swapping Gas Token in popular Flatqube Dex
- All edge cases are covered
Project contains two contract types: GasGiver and GaslessWallet. GasGiver is used to swap Gas Token to EVERs for user, and any TIP3.2 token can be used as Gas Token. GaslessWallet is a wallet that has significant amount of Gas Token and use GasGiver in order to exchange Gas Token to EVERs. One GasGiver can support infinite amount of GaslessWallet
- Gas Token - TIP3.2 token that will be exchanged to gas (EVERs)
- Exchange - exchange Gas Token to EVERs in GasGiver. It can call DEX swap, but also can do it without calling DEX swap (and this is more often case)
- Swap - swap Gas Token to EVERs in DEX (Flatqube). Only GasGiver can call this action in this implementation
Any contract can inherit from abstract GaslessWallet.
When child contract is initialized, it must an _init method of GaslessWallet.
Child contract must already have Gas Token wallet and pass it in _init.
See SampleWallet for example.
Gasless Wallet has two main values - minBalance and minReserve (minBalance < minReserve).
The main logic can be divided is 3 possible cases (here value is transaction values that must be sent):
(balance - value) > minReserve- too many EVERs, transaction can be executed immediately (no message to GasGiver at all)minReserve ≥ (balance - value) ≥ minBalance- transaction can be executed immediately, and another transaction to GasGiver must be sent for exchangingminBalance > (balance - value)- transaction cannot be executed, firstly Gas Token must be exchanged to EVERs. So GaslessWallet safe transaction in memory and waiting for EVERs (case 1 or 2)
Gas Giver is contact that exchange Gas Token to EVERs. In order to optimize gas usage and minimize DEX calls, it exchanges Gas Token only when it doesn't have enough EVERs in balance. So exchanges can be represented as batches (see graphic bellow)
There are some config params that are set on deploy:
tokenRoot- Gas TokendexPair- DEX pair addressslippage- exchange slippage for user Wallets (inConstants.PERCENT_DENOMINATORunit)feePercent- exchange fee that taken by GasGiver (inConstants.PERCENT_DENOMINATORunit)maxGas- maximum amount of EVERs to exchange (get) in one transactionreserve- minimum reserve value in Gas Giver
As described in Gasless Wallet, there are 3 possible cases. The first case is clear and looks like this:

The another two cases are triggers GasGiver. Depending on it balance, there are 2 possible cases. If GasGiver have enough EVERs than GasGiver do simple exchange (without DEX swap). More formally:

In other case (when remains < expectedGas), GasGiver calls DEX swap and then burn WEVERs to get EVERs.

By the way, there is one extremely rare case, when price of Gas Token in pool changed significantly and there is not enough EVERs even after swap. This means that Gasless must send additional Gas Tokens to complete another swap and get enough EVERs
