Project Overview 📄

Overview

Ruby Substate Client will support a efficient way to interface with substrate chain with ruby.

This library will provide convenience methods to deal with SR25519, ED25519 sign and verify message.

Encode/Decode the chain message, submit the sign message to chain by rpc.

Through this grant, we hope to

1. SR25519, ED25519 support.

2. Submit sign extrinsics to chain.

Project Details

1. Develop SR25519 gem.

2. Develop rpc gems inlcude submit extrinsics and batch submit extrinsics.

Apis

• SR25519.keypair_from_seed(seed)
• SR25519.sign(message, keypair)
• SR25519.verify(address, message, signature_result)
• ED25519.keypair_from_seed(seed)
• ED25519.sign(message, keypair)
• Ed25519.verify(address, message, signature_result)
• RbSubstrateClient.submit_sign_extrinsics(params, keypair)
• RbSubstrateClient.utility_batch_submit(params, keypair)

Technology stack

• ruby lang 2.7

Development Status 📖

Much of the technology is already implemented app.uniarts.network. But now the code is in the project, not written as a library. and it needs more tests. We expect that we can refactor, reuse and generalize existing code. write gems to help other ruby developers.
