Hello,
I’ve been interested in smart contracts and there is one thing I can not understand at all.
Info
- in Java/Kotlin using web3j
- using Infura’s API for ITX transactions
In this smart contract there is a function called swap:
// this low-level function should be called from a contract which performs important safety checks
function swap(uint amount0Out, uint amount1Out, address to, bytes calldata data) external lock {
Now what I’m wondering is, how do these functions work?
I read about flash swaps but I do not understand them in this case and something about callbacks, but that I would assume stands for JS callbacks.
If I want to swap token A for token B, what all do i have to do to submit a transaction to Infura?
Thank you very much.
