It was just a small test item for my learning programming.
To learn more, add split and function to withdraw only part of the chips. I sent 0.011 tBTC and want a voucher for 0.001 while withdrawing 0.01.
Here's a 0.001 voucher:KNGKz2LuIH9ONudZ.
Take it if you want testnet Bitcoin.
Thanks for the second test, the split function is a bit tricky to implement, if the value of each chip is in the form of 2 powers, every chip can be used for splitting and merging except for 0.001, I will continue to think about this. As for extracting some of the chips, that's a good suggestion, I'll try to do that when I have some free time!
