While you deploy your contract, your constructor function is called, and it is not marked as payable.

Rebase function in BEP20 token contract

Asked 2022-Mar-11 at 08:46

Can anyone please explain to me the rebase function of this solidity code? I am building a rebase token like Titano.

...

ANSWER

Answered 2022-Mar-06 at 14:50

It changes the total supply by the supplyDelta param value.

A usual approach with rebase tokens is to store each holders stake percentage instead of their absolute token amount. Their actual token amount is then calculated by multiplying the stake percentage by a variable - in this case the _gonsPerFragment value.

Example:

Total supply 100, Alice owns 80% and Bob owns 20% of the tokens. This makes Alice owner of 80 tokens and Bob owner of 20 tokens.

Now lets start a new epoch and rebase the total supply by +200, making it total of 300. Alice now owns 240 tokens (still 80%) and Bob now owns 60 tokens (still 20%).

This seems to be a bug in the compiler.

A small enough number literal (such as 1 or 2 in your example) fits into the type for uint8 (max value 255), so the compiler treats the literal as uint8 type by default.

You need to workaround this by using the typecast function, just as shown in your question.

QUESTION

Unable to deploy smart contract to Polygon, Gas estimation error, Internal JSON-RPC error

Asked 2022-Feb-27 at 22:46

Good afternoon,

I am new to Polygon (but have some Ethereum experience) and I am attempting to deploy the smart contract from the chainlink documentation https://docs.chain.link/docs/fulfilling-requests/ on the Polygon MUMBAI testnet, using remix as my in browser IDE.

I initially attempted to launch the original contract, as published in the docs. I got this error message:

"Gas estimation errored with the following message (see below). The transaction execution will likely fail. Do you want to force sending? Internal JSON-RPC error. { "code": -32000, "message": "execution reverted" }"

When that failed, I trimmed it down to a smaller, more bare bones contract (in case there is a smart contract size limit on Polygon). Here is the trimmed down code:

After going through and commenting line by line, I was able to track down the code that was at fault. I had gone in and changed the LINK address in ChainlinkClient.sol to the mumbai LINK address. As written, the demo code calls setPublicChainlinkToken(); which then assigns the stored value as the link token address. Changing that value to the correct address did not solve my issue. Instead, I used setChainlinkToken(0x326C977E6efc84E512bB9C30f76E30c160eD06FB); and that has cleared up my issue.

I tried all that you mentioned in the discussion here (in other questions) and at https://github.com/smartcontractkit/full-blockchain-solidity-course-py/discussions/522 , however it is not solving the issue for me, I also noticed that the current compiler version remains (current compiler is 0.6.12+commit.27d51765.Windows.msvc).

brownie AttributeError: 'NoneType' object has no attribute 'getEntranceFee'

Asked 2022-Jan-14 at 09:25

Macbook Pro : Monterey

Intel Core i7

Brownie v1.17.2

I am learning solidity according to reference(https://www.youtube.com/watch?v=M576WGiDBdQ&t=25510s).

What I tried to do here, is use brownie to deploy a contract(FundMe) in a script (deploy.py),then write a test script(test_can_fund_and_withdraw.py)

The error occurs when I run the test script.I think it's because in the testing script import the function "deploy_fund_me()" which don't have the function "getEntranceFee()",should import from contract FundMe.sol but in the youtube course ,it works fine.

test script (test_can_fund_and_withdraw.py)
