Tip3ToEver
The Tip3ToEver smart contract defines the logic for swapping Tip3 To Ever.
Smart contract responsible for swapping Tip3 token to Ever.
Derives following classes and interfaces: IAcceptTokensTransferCallback, IAcceptTokensBurnCallback, IEverTip3SwapEvents.
constructor() public
Deploy empty wallet.
function buildExchangePayload(uint64 id, address pair, uint128 expectedAmount) external pure returns (TvmCell)
Build payload constructor for exchanging TIP 3 to EVER, store values from function params to
TVMBuilder instance.Parameters:
Name | Type | Description |
|---|---|---|
id | uint64 | Id of the operation call |
pair | address | Address of the exchange pair |
expectedAmount | uint128 | Expected amount of tokens after exchange |
function onWeverWallet(address _weverWallet) external
Callback deploy for
weverWallet.Parameters:
Name | Type | Description |
|---|---|---|
_weverWallet | address | Address of the WEVER wallet |
function onAcceptTokensTransfer(address /*tokenRoot*/, uint128 amount, address sender, address /*senderWallet*/, address user,TvmCell payload) override external
Callback for swap. If operationStatus is SWAP and value is greater than
SWAP_TIP3_TO_EVER_MIN_VALUE, build success, cancel and resultPayload and transfer from Tip3ToEver wallet to the pair’s wallet.
If operationStatus is CANCEL emit SwapTip3EverCancelTransfer event and call OnSwapTip3ToEverCancel callback and transfer the amount back to the user, if SUCCESS and msg sender is weverWallet, transfer the amount to weverVault wallet.
Else if needCancel var is true transfer value back to the senderParameters:
Name | Type | Description |
|---|---|---|
tokenRoot | address | Address of token root |
amount | uint128 | Amount of tokens to transfer |
sender | address | Address of tokens sender |
senderWallet | address | Tokens sender’s wallet address |
user | address | User’s address for receiving EVER tokens |
payload | TvmCell | Transfer payload data |
function onAcceptTokensBurn(uint128 /*amount*/, address /*walletOwner*/, address /*wallet*/, address user, TvmCell payload) override external
Callback for burn if the swap succeeded, emits
SwapTip3EverSuccessTransfer event and call callback onSwapTip3ToEverSuccess.Parameters:
Name | Type | Description |
|---|---|---|
amount | uint128 | Amount of tokens to burn (optional) |
walletOwner | address | Address of wallet owner |
wallet | address | Wallet address |
user | address | User’s address that canceled exchange |
payload | TvmCell | Burn tokens payload data |
SwapTip3EverSuccessTransfer(address user, uint64 id);
Emitted inside
onAcceptTokensTransfer callback when Tip3 tokens are successfully swapped to EVERs.SwapTip3EverCancelTransfer(address user, uint64 id);
Emitted inside
onAcceptTokensTransfer callback when swap is canceled.Last modified 7mo ago
