Broadcast Txn failed

Thank you, tsachi. After added the “close”, the tx has been sent successful. But where did the 0.000007 come from?

Broadcast Txn failed

I tried to use the api of algoexplorer.io to broadcast, got similar error:

{"message":"TransactionPool.Remember: transaction 4NPP7KEQVOK5I23H7TRKP6CP5TM4XUVWCF23KXQ6BDZB3ORSV6NQ: account DBOXO4PMUECVI7ZJKMLCZDPXD6ORYRBTNMSTFXAHJTQCUKVX5GUG5JEEYE balance 3 below min 100000 (0 assets)"}

Need a little ALGO for testing my wallet

Yes, I also would like to test on testnet. How could I get some testnet coin? And is the testnet using the same address format?

Can algo support Permissioned blockchain?

Sorry, I don’t know. I’m glad to know what is your definition of “permission blockchain.”
