Hey i run a full bitcoin+lightning node on a rpi. Can anyone eli5 me how can i verify my own tx if send some coins from an exchange to a public address i control?

Lets say i plug in my hw, send some coins, then i wanna actually verify if i got those coins or at least they are (verify able) on the mempool waiting to be mined.

I have always struggled with the how do i really “verify, don’t trust” quote.

Thanks in advance.

  • You don't need to do anything. Your lightning client needs to somehow learn about incoming transactions, and it uses the node it's pointed to for that. If that is a full node you trust (because you operate it yourself), you automatically get that trust carried over to your lightning client. – Pieter Wuille Apr 8 '19 at 19:34
  • @PieterWuille yeh i have no issues when i receive/send thru my node. My issue was more related when i do external tx, for example when a friend sends me to an address generated from my hw and the latter isn’t specially used with the full node. – Lebowski Apr 8 '19 at 19:42
  • @Lebwoski If you're talking about another wallet, the answer is the same: make that wallet use your full node for validation (many wallet implementations let you select a trusted full node to connect to). – Pieter Wuille Apr 8 '19 at 20:47
  • @PieterWuille unfortunetly not the ledger live :( ! But soon willl start using it either with bitcoin core or electrum personal server ! Thanks again for the heads up! – Lebowski Apr 8 '19 at 21:09

You should use the gettransaction (TXID) command that returns information about a transaction belonging to your wallet. Then just check the confirmations field.

  • I don't understand what this achieves. If it's a transaction in your own (full node) wallet, it wouldn't be there if it isn't valid. If it's a transaction of an external wallet, gettransaction won't work on it. – Pieter Wuille Apr 8 '19 at 20:46
  • I literally can't argue with you. I read the question quickly and answered something else. (btw: huge fan! thanks for all!) – Tiago Loriato Simões Apr 8 '19 at 21:32
