EverWeverToTip3
The EverWeverToTip3 defines the logic for swapping EVERs in combination with WEVERs to Tip3 tokens.
Smart contract responsible for swapping EVERs in combination with WEVERs to Tip3 tokens.
Derives following classes and interfaces: IAcceptTokensTransferCallback, IAcceptTokensBurnCallback.
constructor() public
Deploy EverToTip3Gas empty wallet.
function buildExchangePayload(uint64 id, uint128 amount, address pair, uint128 expectedAmount, uint128 deployWalletValue) external pure returns (TvmCell)
Builds payload by filling the TVM builder instance with data derived from function params, returns builder converted to cell.
Parameters:
Name | Type | Description |
|---|---|---|
id | uint64 | Operation id |
amount | uint128 | Amount of tokens to exchange |
pair | address | Address of the exchange pair |
expectedAmount | uint128 | Expected amount of tokens after exchange |
deployWalletValue | uint128 | Deploy value |
Return Value:
Type | Description |
|---|---|
TvmCell | Exchange payload in cell format |
function onWeverWallet(address _weverWallet) external
Deploys Wever wallet for the contract using
_weverWallet address from the function params.Parameters:
Name | Type | Description |
|---|---|---|
_weverWallet | address | Address used to initialize wever wallet |
function onAcceptTokensTransfer(address /*tokenRoot*/, uint128 amount, address /*sender*/, address /*senderWallet*/, address user, TvmCell payload) override external
Callback if swap between ever and tip 3 is successful.
Calls
onSwapEverToTip3Success callback to the user, SwapEverToTip3SuccessTransfer event is emitted and tip 3 tokens are sent to a user wallet by calling TokenWallet’s transfer method.
If conditions are not fulfilled swap is canceled and tokens are returned to sender’s wallet.Parameters:
Name | Type | Description |
|---|---|---|
tokenRoot | address | Address of token root (optional) |
amount | uint128 | Amount of tokens to transfer |
sender | address | Address of tokens sender (optional) |
senderWallet | address | Tokens sender’s wallet address (optional) |
user | address | User’s address for receiving tip3 tokens |
payload | TvmCell | Transfer payload data |
function onAcceptTokensBurn( uint128 /*amount*/, address /*walletOwner*/, address /*wallet*/, address user, TvmCell payload) override external
If result of swap was canceled call this callback, it emits
SwapEverToTip3CancelTransfer event and calls onSwapEversToTip3Cancel callback.Parameters:
Name | Type | Description |
|---|---|---|
amount | uint128 | Amount of tokens to burn (optional) |
walletOwner | address | Address of wallet owner (optional) |
wallet | address | Wallet address (optional) |
user | address | User’s address that canceled exchange |
payload | TvmCell | Burn tokens payload data |
