Add Etherum Signature Support @ CLI

[notlesh]

While the api supports ethereum signatures (e.g. polkadot-js/api#2499), the CLI does not accept anything other than sr25519 or ed25519.

@jacogr Just to clarify: we want to be able to sign transaction from our dev address, which is generated from a private key or from mnemonic+derivepath, how do we do that from the cli (which only accepts seeds as of now)?

[jacogr]

See https://github.com/polkadot-js/tools/blob/master/packages/api-cli/src/api.ts#L208

It should "just work" if this is adjusted and a hex privateKey is passed - https://github.com/polkadot-js/tools/blob/master/packages/api-cli/src/api.ts#L75 (theoretically, types would need to be passed alongside as well)

@notlesh Do you mind cloning this branch: https://github.com/PureStake/tools/tree/jlm-add-eth-derivation-to-cli
and then cd api-cli and try using the api with yarn run:api (as explained here https://github.com/PureStake/tools/tree/master/packages/api-cli)
Gerald should be created with either
seed sock milk update focus rotate barely fade car face mechanic mercy/m/44\'/60\'/0\'/0/0
OR '0x070dc3117300011918e26b02176945cc15c3d548cf49fd8418d97f93af699e46
as seed input

@notlesh Actually nvm the mnemonic and private key I mentioned above, those aren't for Gerald and I don't know the mnemonic for Gerald

@jacogr When trying to test #220 I try to run yarn run:api —ws 30544 query.system.account 0x6Be02d1d3665660d22FF9624b7BE0551ee1Ac91b and I get

internal/modules/cjs/loader.js:1080
      throw new ERR_REQUIRE_ESM(filename, parentPath, packageJsonPath);
      ^

Error [ERR_REQUIRE_ESM]: Must use import to load ES Module: /Users/antoineestienne/GitHubRepo/tools/node_modules/@polkadot/x-rxjs/index.js
require() of ES modules is not supported.
require() of /Users/antoineestienne/GitHubRepo/tools/node_modules/@polkadot/x-rxjs/index.js from /Users/antoineestienne/GitHubRepo/tools/node_modules/@polkadot/api/promise/index.cjs is an ES module file as it is a .js file whose nearest parent package.json contains "type": "module" which defines all .js files in that package scope as ES modules.
Instead rename index.js to end in .cjs, change the requiring code to use import(), or remove "type": "module" from /Users/antoineestienne/GitHubRepo/tools/node_modules/@polkadot/x-rxjs/package.json.

The above is hopeful fixed in master. Took me ages to take a look, it has not worked since the update to the 4.x api

(Attempted a fix as part of an unrelated issue where docker was also problematic)

Are you refering to ES module error or Ethereum singing itself? @jacogr

[jacogr]

ES module error as described.

[joelamouche]

Unfortunately this #239 is still a thing
