I have noticed different value
in freeFromUpTo
:
(gasSpent + 14154) / 41947
modifier discountCHI {
uint256 gasStart = gasleft();
_;
uint256 gasSpent = 21000 + gasStart - gasleft() + 16 * msg.data.length;
chi.freeFromUpTo(msg.sender, (gasSpent + 14154) / 41947);
}
(gasSpent + 14154) / 41130
modifier discountCHI {
uint256 gasStart = gasleft();
_;
uint256 gasSpent = 21000 + gasStart - gasleft() + 16 * msg.data.length;
chi.freeFromUpTo(msg.sender, (gasSpent + 14154) / 41130);
}
Which is the right one?
As a user who want to use the Chi token in my own solidity contracts, I want to be able to import the interface of the Chi token directly from Github so that I don't have to manually create it (and risk making a silly mistake).
Create the file contracts/IChiToken.sol
with the interface of the ChiToken.
EDIT: Uniswap did this and it's very convenient:
wget -nc https://raw.githubusercontent.com/Uniswap/uniswap-v2-core/master/contracts/interfaces/IUniswapV2Pair.sol
As a USER who can mint
CHI token
, I want to add it in my contract so when other users execute some functions in my contract, they will cost less gas, so if possible, please add an example for how do I integrate CHI token
into my contracts?
Can I test it in the testnet anyway
