Guys can someone suggest formula to calculate user shares from total amount of tokens in pool that many users put tokens in? The following works fine if there is only 1 user invested in the said pool but when users increase it always return 0, any ideas whats wrong?

uint256 userPoolSharePercent = (userBetAmount / pooledForThisOutcome) * 100;
calculateUserPoolWeight = (totalPooledAmountForThisMatch * userPoolSharePercent) / 100;

Have you looked at this maybe it can help

ty, will check it now i hope it help

mappings

or arrays whatever you use, but in Solidity it's a norm tu use mappings due to evm being a turing complete machine

mapping (address => uint ) balances


fn example()...
{
calculate the amount %

balances[user] - now change accordingly
}

this takes a mapping of type uint for each address

and thus allowing the contract to store/know the balance of an address

why use priv key to see balance😕

can anyone explain how hybrid stablecoins function in a nutshell?

How do they algorithmically decide the burn-mint when it's also backed by fiat

what if fiat falls?

everything fall apart

and a new era will begin

🤔 I suppose, but people say frax aint like luna coz it's hybrid

How does it manage the depeg risk

In ICO contracts what's the best way to bootstrap liquidity from the ICO to dex?

It's a new feature we're planning to integrate...

Is it possible tho?

Also, can I convert an already existing wallet into a Multi-Sig wallet?

Any help with this please?

No, if it's an eoa it can't become a sc keeping the same address

You can't. Multi sig is essentially a contract with multiple owners. Its not possible to convert an existing eoa wallet to such smart contract

It is possible to convert an existing wallet into a multi-sig wallet, but it depends on the type of wallet you have and whether it supports multi-sig functionality.

EVM doesn't support it

function Participate() public {
UserInfo storage userInfo = LottoUserInfo[msg.sender];
uint256 balance = GetTokenBal(msg.sender);
require(started,"lotto not started");
require(!hasParticipated[msg.sender], "User has already participated");
require(balance >0 , "Not Enough Balance of Tokens to buy TICKET" );
require(participantList.length < MaxParticipantCap, "Max participants reached");
require(userInfo.ClaimedLastParticipation,"Claim Your Last Participation Rewards Before Participating");
IERC20(LottoToken).transferFrom(msg.sender, address(this), CurrentTicketPrice);
uint256 f = CurrentTicketPrice.mul(feeAmount).div(10000);
uint256 amtAfterFee = CurrentTicketPrice.sub(f);
uint256 toLockAndPool = amtAfterFee.div(2);

ISwapRouter.ExactInputParams memory params =
ISwapRouter.ExactInputParams({
path: abi.encodePacked(Stable1, poolFee, Stable2, poolFee, WETH),
recipient: msg.sender,
deadline: block.timestamp,
amountIn: f,
amountOutMinimum: 0
});

uint256 amountOut = swapRouter.exactInput(params);
Treasury.add(amountOut);
Lock(msg.sender, toLockAndPool);
RewardPool = RewardPool.add(toLockAndPool);
participantList.push(msg.sender);
hasParticipated[msg.sender] = true;
userInfo.LottosParticipated = userInfo.LottosParticipated.add(1);
emit ParticipantRegistered(msg.sender, CurrentTicketPrice);
}


will doing this call a swap?

nvm i made a typo

but still can anyone help me what i am doing wrong, i know something is not right but i can't seem to identify where

in the contract

bro how can we receive BNB or any other NATIVE token into our contract ??

can we use msg.value like receiving ETH ?

yes

for evm

my idea was when user buy the token, they have to pay with BNB or USDT

is it possible using msg.value ?

yes

for others it's transfer, transferFrom

okay bro, thanks

https://docs.soliditylang.org/en/v0.8.19/contracts.html#receive-ether-function
or
https://docs.soliditylang.org/en/v0.8.19/contracts.html#fallback-function
or
payable
https://docs.soliditylang.org/en/v0.8.19/grammar.html#a4.SolidityParser.stateMutability

those for native crypto (ETH is not a token is a crypto)
for tokens (erc20), you can implement the IERC20 interface

The secret sauce is under balanceOf()

🤔

where lot of us started
https://github.com/safemoonprotocol/Safemoon.sol/blob/main/Safemoon.sol

Yes, msg.value can be used to receive Ether (ETH) in a Solidity contract. When a user sends ETH to a contract, it can be accessed in the contract using the msg.value keyword, which represents the amount of Ether sent in the transaction.

guys any idea how to deploy to BSC ? cause binance are banned in my country

it can't fetch the chain ID, i use VPN but still can't

this is testnet RPC url: https://data-seed-prebsc-2-s1.binance.org:8545

failed to get chainId, falling back on net_version...

i got this errors

Whats with the chatGPT answers

bruh

Rug

looks like exploiter

Yeah I’m sure that’s what coroney or whatever the dudes name is will throw it on lol.

😂😂

too bad on DeFi you never know :\

please enable sticker and GIF

that's up to the group owner

Oh no we got exploited!

*wipes tears with bnb*
-coroney, probably.

top meme of the year😂

The attacker took advantage of the public burn() function, this function let any user burn tokens from ANY other address (code attached).

The attacker used this function to remove SFM tokens from the Safemoon-WBNB Liquidity Pool, artificially raising the price of SFM.

The attacker was then able to sell SFM into this LP at a grossly overpriced rate within the same transaction, wiping out the remaining WBNB in the liquidity pool.

Apparently that’s what happend to safemoon.

when is that happen ??

that is alot of BNB bro 😃

It's on ARB blockchain...
Does that count? or change anything?

can anyone send me some goerli, just enough for 3-4 tx

I dont have much but send your address

Okay coming

thanks 🙏

anyone heard about brics currency? will it be like a stable backed by gold or something else? cbdc?

does anyone have any info

Yes, the BRICS countries (Brazil, Russia, India, China, and South Africa) have been exploring the possibility of creating a common cryptocurrency, sometimes referred to as the BRICS currency or BRICScoin. While there have been some discussions about this idea, there is no official plan or timeline for the creation of such a currency at this time.

It is not clear what form a potential BRICS currency would take, as there are many different approaches to designing a cryptocurrency. Some proponents of a BRICS currency have suggested that it could be backed by gold or other assets, similar to a stablecoin, in order to provide stability and avoid the volatility of other cryptocurrencies. Others have suggested that a BRICScoin could take the form of a central bank digital currency (CBDC), which would be issued and backed by the central banks of the BRICS countries.

At this point, it is difficult to say what the future holds for a potential BRICS currency. While there has been some interest and discussion around the idea, it remains to be seen whether or not such a currency will be created, and what form it would take if it is.

ChatGPT strikes again.

🙈😂

😃😃

there are "devs" doing interview with those
seems the "tx.origin" question always breaks their soul

yoyo

How’s you doing Karola?

but that's not how it's calculated ig
