| ## Evaluation V1 | ||
|
|
||
| ### sr25519 and Sign & Verify | ||
|
|
||
| The [application](https://github.com/w3f/Grants-Program/blob/master/applications/Polkadart.md#milestone-4-) especify a research to decide the best way to support sr25519. Could you provide the explanation and the conclusion of this research? | ||
|
|
||
| The example provided to sr25519 and Sign & Verify worked. | ||
|
|
||
| ```dart | ||
| void main() { | ||
| final msg = utf8.encode('hello friends'); | ||
| final signingCtx = utf8.encode('example'); | ||
| final merlin.Transcript signingTranscript = | ||
| Sr25519.newSigningContext(signingCtx, msg); | ||
| final merlin.Transcript verifyTranscript = | ||
| Sr25519.newSigningContext(signingCtx, msg); | ||
| final keypair = Sr25519.generateKeyPair(); | ||
| final (priv, pub) = (keypair.secretKey, keypair.publicKey); | ||
| final Signature sig = priv.sign(signingTranscript); | ||
| final (ok, _) = pub.verify(sig, verifyTranscript); | ||
| assert(ok == true); | ||
| print(ok); | ||
| } | ||
| ``` | ||
|
|
||
| ``` | ||
| user@localhost:~/Documents/test/demo$ dart run bin/demo.dart | ||
| true | ||
| ``` | ||
|
|
||
| ### Custom Signed Extensions | ||
|
|
||
| I tried to run the example, but I received an error related to balance. | ||
|
|
||
| ``` | ||
| user@localhost:~/Documents/polkadart/examples$ dart run bin/extrinsic_demo.dart | ||

| ### Multisig Account | ||
|
|
||
| In this example, I needed to add the package `polkadart_cli`. | ||
|
|
||
| ``` | ||
| user@localhost:~/Documents/polkadart/packages/polkadart$ dart run polkadart_cli:generate -v | ||
| Could not find package `polkadart_cli` or file `polkadart_cli:generate` | ||
| ``` | ||
|
|
||
| After that, I needed to add the 'polkadart' section. | ||
|
|
||
| ``` | ||
| user@localhost:~/Documents/polkadart/packages/polkadart$ dart run polkadart_cli:generate -v | ||
| Building package executable... (11.2s) | ||
| Built polkadart_cli:generate. | ||
| Unhandled exception: | ||

| #4 _RawReceivePort._handleMessage (dart:isolate-patch/isolate_patch.dart:184:12) | ||
| ``` | ||
|
|
||
| After that, I received an error related to balance. | ||
|
|
||
| ``` | ||
| user@localhost:~/Documents/polkadart/packages/polkadart$ dart run example/multisig_example.dart | ||
| Unhandled exception: | ||
| Exception: {code: 1010, message: Invalid Transaction, data: Inability to pay some fees (e.g. account balance too low)} | ||

| ``` | ||
|
|
||
| I couldn't find the seed or the address to give some balance. Could you help me with that? | ||
|
|
||
| ### Tests | ||
|
|
||
| I tried to run the tests using Docker. All tests passed until the tests in the package substrate_metadata killed the program. | ||
|
|
||
| ``` | ||
| polkadart-tests-1 | substrate_metadata: | ||
| polkadart-tests-1 | Killed | ||
| polkadart-tests-1 | | ||
| polkadart-tests-1 | | ||
| 02:06 +13583: test/chains/kusama/spec_version_test.dart: Spec Versions Test init spec version file -------------------------------------------------------------------------------- | ||
| polkadart-tests-1 | | ||
| polkadart-tests-1 | $ melos exec | ||
| polkadart-tests-1 | └> dart test --coverage="coverage" | ||
| polkadart-tests-1 | └> FAILED (in 1 packages) | ||
| polkadart-tests-1 | └> substrate_metadata (with exit code 137) | ||
| polkadart-tests-1 | | ||
| polkadart-tests-1 | melos run test | ||
| polkadart-tests-1 | └> dart run melos exec --scope="${SCOPE:-*}" -c 1 --fail-fast -- 'dart test --coverage="coverage"' | ||
| polkadart-tests-1 | └> FAILED | ||
| polkadart-tests-1 | ScriptException: The script test failed to execute. | ||
| polkadart-tests-1 exited with code 1 | ||
| ``` | ||
|
|
||
| I ran again, monitoring the resources. When the substrate_metadata tests started, memory usage increased until use all the memory. I stopped the test because it had frozen my computer before. It seems to be a memory leak problem or do I need more memory to run these tests? | ||
