+## 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.

+### 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)

+
+After that, I received an error related to balance.
+
+```

+```
+
+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 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?
