Generate extrinsic classes #315

leonardocustodio · 2023-07-11T00:48:44Z

Milestone

Example:

  final Polkadot polkadot = Polkadot.url(Uri.parse('wss://rpc.polkadot.io'));
  final call = polkadot.tx.balances.transferAll(dest: 'dest', keepAlive: true)

Nice! remember to increment the package version and update the CHANGELOG.md with a description of the new features.

If I'm allowed to ask guys just wondering if you about accept this PR when it might be merged ? I was seeking for a weeks for this sort of solution:)

leonardocustodio · 2023-07-26T12:51:27Z

Hello @kemalinnowise , Right now it only generates an encoded call and the payload to sign. Is that enough for you? If so we can merge it already.
I'm still making the part where it signs the payload and constructs the whole extrinsic. I think it might be done by the weekend.

Hi @leonardocustodio !
First of all let me express my gratitude. I really appreciate your impact!
This lib is awesome. No rush so far however looking forward to update cli with all those incredible new features!

packages/polkadart/lib/extrinsic/extrinsic_payload.dart

packages/polkadart/lib/extrinsic/signed_extensions/substrate.dart

packages/polkadart_cli/lib/src/generator/pallet.dart

@leonardocustodio Hi! Hope U doing well!
May I ask for update with one generates an encoded call and the payload to sign ?:) This week we start working on Extrinsics

Hello @kemalinnowise, unfortunately I was not able to finish this yet. But you can use this branch directly and here is an example on how you can accomplish what you want (create signed extrinsics):

import 'package:convert/convert.dart';
import 'package:demo/generated/polkadot/polkadot.dart';
import 'package:polkadart/polkadart.dart';
import 'package:polkadart_keyring/polkadart_keyring.dart';

Future<void> main(List<String> arguments) async {
  final provider = Provider.fromUri(Uri.parse('wss://rpc.efinity.io'));
  final api = Polkadot(provider);

  final keyring = await Keyring.fromMnemonic(
      "toward disagree come neither clay priority bamboo chat tiny fabric damp aisle//0");
  final publicKey = hex.encode(keyring.publicKey.bytes);
  print('Public Key: $publicKey');

  final anotherHexPayload = hex
      .encode(SigningPayload.createSigningPayload(payloadToSign, api.registry));
  print('Payload: $anotherHexPayload');

  final signature = keyring.sign(payload);
  final hexSignature = hex.encode(signature);
  print('Signature: $hexSignature');
  // d19e04fc1a4ec115ec55d29e53676ddaeae0467134f9513b29ed3cd6fd6cd551a96c35b92b867dfd08ba37417e5733620acc4ad17c1d7c65909d6edaaffd4d0e

  final extrinsic = Extrinsic(
          signer: publicKey,
          method: call,
          signature: hexSignature,
          era: era,
          nonce: nonce,
          tip: tip)
      .encode(api.registry);

  final hexExtrinsic = hex.encode(extrinsic);
  print('Extrinsic: $hexExtrinsic');
  // 2d0284006802f945419791d3138b4086aa0b2700abb679f950e2721fd7d65b5d1fdf8f0201d19e04fc1a4ec115ec55d29e53676ddaeae0467134f9513b29ed3cd6fd6cd551a96c35b92b867dfd08ba37417e5733620acc4ad17c1d7c65909d6edaaffd4d0e0028000a03008eaf04151687736326c9fea17e25fc5287613693c912909cb226aa4794f26a48a10f
}

Please note a few of those stuff were added to a helper method in this branch.
Also the call value is what you can get from final call = polkadot.tx.balances.transferAll(dest: 'dest', keepAlive: true)
Any doubts, let me know.

Actually, I talked with my manager and he allowed me to help you. I just not good at substrate and blockchain. But this feature is critical in our project, so if you accept my help and ready to outsource some work to me, I'm ready.

leonardocustodio · 2023-08-21T20:32:11Z

Sure, that would be great. Can you check if you can make a fully working extrinsic first using the method above?

kemalinnowise · 2023-08-23T11:57:30Z

I would love to check but for some reason neither case from picture above or others I've tried won't pull specific branch. Like pub get proceed fine but I can't see any package in

In case if need here is my -flutter doctor :

My suggestion to import polkadart in your project at this moment would be clone the whole repository inside your project folder in a polkadart folder for example and import it this way

  substrate_metadata:
    path: polkadart/packages/substrate_metadata
  polkadart_scale_codec:
    path: polkadart/packages/polkadart_scale_codec

My suggestion to import polkadart in your project at this moment would be clone the whole repository inside your project folder in a polkadart folder for example and import it this way
  substrate_metadata:
    path: polkadart/packages/substrate_metadata
  polkadart_scale_codec:
    path: polkadart/packages/polkadart_scale_codec

I've tried specified approach however given errors won't allow me to proceed:

Because every version of substrate_metadata from path depends on polkadart_scale_codec from hosted and sandbox depends on polkadart_scale_codec from path, substrate_metadata from path is forbidden.
So, because sandbox depends on substrate_metadata from path, version solving failed.

Also I've tried to use various options depending on some of packages separately won't work as well

P.S. Is there any option to communicate with you via Discord or whatever for more convenience ?

leonardocustodio · 2023-08-23T19:10:05Z

Here is a demo project which you can use to learn how to setup. Please note you need melos installed. Also you might need to fix the directories in pubspec_overrides.yaml.

demo.zip

kemalinnowise · 2023-08-24T11:40:53Z

Hello!

I downloaded the demo project and configured the dependencies from the repository, everything run and works for me except for the generation in my projects pubcpec.yaml I use the following to generate Mychain instead Poladot:

So I've tried replace this lines in demo project with one from my project and run:

dart pub run polkadart_cli:generate -v

The command line throws given error:

Hello!

I downloaded the demo project and configured the dependencies from the repository, everything run and works for me except for the generation in my projects pubcpec.yaml I use the following to generate Mychain instead Poladot:

So I've tried replace this lines in demo project with one from my project and run:

dart pub run polkadart_cli:generate -v

The command line throws given error:

Sorry that was my bad. For some reason watcher won't work properly, I fixed bug and now things work fine on my side. Seems to me Existing changes is enough for my project) What is the next steps, how can I be helpful ?

kemalinnowise · 2023-08-24T17:53:04Z

Also I try replace your example with my and got given error while generate classes:

lib/generated/mychain/pallets/evm.dart:128:35: Error: The method 'call' isn't defined for the class '$Call'.
 - '$Call' is from 'package:sandbox/generated/mychain/types/pallet_evm/pallet/call.dart' ('lib/generated/mychain/types/pallet_evm/pallet/call.dart').
Try correcting the name to the name of an existing method, or defining a method named 'call'.
    final _call = _i8.Call.values.call(
                                  ^^^^

And one more thing:

final extrinsic = Extrinsic(
          signer: publicKey,
          method: call,
          signature: hexSignature,
          era: era,
          nonce: nonce,
          tip: tip)
      .encode(api.registry);

  final hexExtrinsic = hex.encode(extrinsic);
  print('Extrinsic: $hexExtrinsic');
  // 2d0284006802f945419791d3138b4086aa0b2700abb679f950e2721fd7d65b5d1fdf8f0201d19e04fc1a4ec115ec55d29e53676ddaeae0467134f9513b29ed3cd6fd6cd551a96c35b92b867dfd08ba37417e5733620acc4ad17c1d7c65909d6edaaffd4d0e0028000a03008eaf04151687736326c9fea17e25fc5287613693c912909cb226aa4794f26a48a10f

Where to send this serialised extrinsic ?

leonardocustodio · 2023-08-25T18:43:08Z

This would give you an encoded call:

  final dest = $MultiAddress().raw(hex.decode(
      "06d0f1711a6d0408135ff35043137210d0563f3d02f17e6cdacec1f6e23a5a17"));
  final runtimeCall = api.tx.balances.transferAll(dest: dest, keepAlive: true);
  final call = hex.encode(runtimeCall.encode());
  print(call);

Where api is:

  final provider = Provider.fromUri(Uri.parse('wss://rpc.efinity.io'));
  final api = Polkadot(provider);

And this Polkadot is actually the name that you put on the chains, and should come from /lib/generated/<name>.dart

leonardocustodio · 2023-08-25T18:51:26Z

Where to send this serialised extrinsic ?

That's actually one thing that you can help out if you wish. Basically, you need to make a RPC call to author.submitExtrinsic passing the signed extrinsic. There is already the RPC interface, the system calls are done through it. But we have not made the other interfaces.

clangenb · 2023-10-06T11:32:11Z

Hi there, maintainer of https://github.com/encointer/encointer-wallet-flutter here. We want to get rid of our unstable webView that runs a @polkadot-js/api, and want to have a pure dart<>substrate interface. The work you have done here is wonderful.

Once this PR is merged, we would love to try out your lib! Is there any estimate, is this still being worked on?

leonardocustodio · 2023-10-06T11:59:24Z

Hello @clangenb , yes we have resumed the development and our ETA for our next milestone is in about two months, here is the list of things that will be released in this next milestone:

 3a.  | Substrate Uri    | Implement Substrate's standard derivation format that applies to seeds and mnemonics. |
| 3b.  | Encrypt/Decrypt  | Use Substrate's Bip39 password to encrypt/decrypt seeds and mnemonics. |
| 3c.  | Ed25519          | Support Ed25519 signatures and key derivation |
| 3e.  | Sign & Verify    | Sign and verify messages using ed25519 keypairs |
| 3f.  | Substrate Signed Extensions | Support substrate's signed extensions |
| 3g.  | AssetHub Signed Extensions | Support AssetHub's signed extensions |
| 3h.  | Transaction Subscriptions   | Support transaction subscription |
| 3i.  | Event Subscriptions         | Support runtime event subscription |
| 3j.  | Keyring          | Create a package that manage a set of keys in a consistent environment |
| 3k.  | Crypto           | Utilities needed for signing, hash and encode/decode messages |

clangenb · 2023-10-06T12:06:07Z

Awesome thanks for the swift reply - cool features are in the pipeline! What I can't see in this milestone list is extrinsic creation and calling the author RPC to submit the extrinsic and listen for tx status updates (so essentially work that builds upon this PR), do you also have some info regarding this?

leonardocustodio · 2023-10-06T12:09:01Z

Yep, all that is included in this same milestone but signing the extrinsics only with ed25519 will be supported by now,. For sr25519 it will be in the next milestone that should be delivered next year.

Awesome, thank you so much for all these updates. I was curious about your library and started integrating the current state into our codebase and generated some types just to get a feeling about it - works flawlessly so far.

My current endeavour is to send an already signed and scale-encoded extrinsic to our chain and listen for the extrinsic status updates. As I have found your library meanwhile, I might use your state/system apis as an inspiration and implement parts of the author api analogously to them. If your interested, I could maybe upstream it.

leonardocustodio · 2023-10-08T20:42:46Z

prs are always welcome, feel free to send any if you want to 😄

leonardocustodio · 2023-10-21T21:47:47Z

@clangenb, you can now submitAndWatchExtrinsic using this PR, though the PR is not done yet.

stale

clangenb · 2023-10-25T02:02:18Z

Hi there, thanks a lot! I have also made my own implementation meanwhile, as I needed quite some boilerplate around sending the extrinsic and moreover finding out whether the extrinsic was a success or not. Some of the code is a bit opinionated, so I am not sure if it fits in a library like polkadart, but you can have a look at it if you like: encointer/encointer-wallet-flutter#1529.
