I get the structure, I think. 

Here's maybe a better question:

Can someone give an example of a JSON object that I could pass to the API and be able to successfully create a raw transaction?

Is the format that there is a "params" property with all the inputs in it, and, uniquely, a separate property after that whose name is the send-to address, and value is the send amount?  Every other command uses only elements within the params array, but to look at the format given:

 [{"txid":txid,"vout":n},...] {address:amount,...} 

this would seem to differ.  Has anyone created a raw transaction with the API, or only by shelling out to bitcoind?

I've taken a project called "bitnet" for .NET and added some functions that didn't exist in the API list at the time it was written.  That was straightforward except for createrawtransaction.

Here's an example Gavin used when demonstrating how to create spending transactions for multisig wallets.

createrawtransaction '[{"txid":"3c9018e8d5615c306d72397f8f5eef44308c98fb576a88e030c25456b4f3a7ac","vout":0,"scriptPubKey":"a914f815b036d9bbbce5e9f2a00abd1bf3dc91e9551087","redeemScript":"52410491bba2510912a5bd37da1fb5b1673010e43d2c6d812c514e91bfa9f2eb129e1c183329db5 5bd868e209aac2fbc02cb33d98fe74bf23f0c235d6126b1d8334f864104865c40293a680cb9c020 e7b1e106d8c1916d3cef99aa431a56d253e69256dac09ef122b1a986818a7cb624532f062c1d1f8 722084861c5c3291ccffef4ec687441048d2455d2403e08708fc1f556002f1b6cd83f992d085097 f9974ab08a28838f07896fbab08f39495e15fa6fad6edbfb1e754e35fa1c7844c41f322a1863d46 21353ae"}]' '{"1GtpSrGhRGY5kkrNz4RykoqRQoJuG2L6DS":0.01}'


What this looks like to me is an array containing one JSON object followed by a JSON object.  There's no indication that last string is part of an array of parameters, and if I do pass it as an element in an array it gives me a server error.

For example, this does not work:

[[{"txid":"31f9b9a76aa82b4fadc5bec05536124f7302e942c4488fa5030f9f34bf35f827","vout":1,"scriptPubKey":"a9141986c0fc06de64d85a8fe0314728de453f38ff2d87","redeemScript":"522103ce8aaa1bb0403148d9327863b40f0abbf9aebac3d7a996866c8a15022a1d5d5d2103be511 208d869328ebcd3b61d3387ee9ad47a0f685a13ab34946e0563203d9ab552ae"}],{"12Z8vEbkfwqm3xytQWYXCALTjRg3cRFEyh":0.005}]

Am I missing something?  I'm new with JSON but everything else has seemed straightforward.

sweet.  Because the bitnetclient for .net that was written is great as far as it goes, but it doesn't seem to support signrawtransaction or sendrawtransaction.  I'll be back when I get this far.  Thanks a ton

This seems a great place to ask this question.

I need to build a windows app that can do just a few specific things:

1) create a local wallet with one or more addresses
2) display the public key of those addresses to the user
3) accept a cut-and-paste raw transaction, decode it, and show the user what the transaction does
4) Allow user to sign and send transaction to miners

If the IKVM .dll conversion works as expected, will this be pretty straightforward?

I would swear I saw different behavior generating from seed between the full client and the portable one.  If you sent the coins to the addresses generated by the portable, I would try regenerating from seed with the portable version again and see what happens.

Hi.  I'm setting up a system that will use the native escrow function.  The plan is that I will create the transactions using bitcoind, but that the users will use the console in Electrum, it being vastly preferable they do that rather than worry about downloading the blockchain.  Electrum is my preferred client anyway.

Could someone provide me with an example of valid input to the signrawtransaction() function?

I am planning to create the input they will cut and paste into electrum programmatically, and I was thinking along the lines of

u = signrawtransaction("valid_input")
sendrawtransaction(u)

with some instructions on how to decode and inspect if they want to (that I figured out).

Any help would be greatly appreciated!

Hi!  Hoping the mods can validate my user to post in the electrum forums.

I need help with scripting in the python console so that I can set up escrow transactions.

Specifically, since there is no explicit command reference that I can find, I need to ask how precisely to feed data into the relevant functions.

Thank you!
