automated multisig DOGE gateway alpha test release!
it is still incomplete, need to add a lot of error handling, but it does do deposits and withdraws, at least in simple cases.
It rounds down to the nearest .001. To deposit DOGE into your NXT AE, just send DOGE from your wallet to the address you get from get_dogeaddr program. After about 10 minutes it should arrive. To withdraw DOGE into your wallet, just use the AE transfer asset function and return it to 18232225178877143084. Right now, not checking for 10 confirmations, so it should arrive in a few minutes.
I just want to make sure basic functionality is there and test simultaneous requests from different accts. Also, support for fractions are pretty new, probably have some issues there.
Just a quick sanity test to get me a list of must fixes and I can do that and add error checking and consistency checking this weekend. Also need a lot of realtime monitoring so that you can see the progress of your (and other) transaction.
There is every chance that with more than a few people using this at once, things wont go quite right. Maybe even confuse the servers into deadlocking as they need to reach consensus exactly on every detail of the rawtransaction.
If you want to test, but cant compile the dogeaddr program, just post your DOGE address and NXT address and I will do it manually. Also, if you need some DOGE, just ask.
James
compile with: "gcc -o get_dogeaddr doge_addr.c -lcurl"
usage: ./get_dogeaddr <NXT addr> <NXT acct passkey> <coin withdraw addr> [gatewayid]
valid gatewayids are 0, 1, or 2 it defaults to 0 if you dont specify
get_dogeaddr.c
