Cosmostation

• https://www.cosmostation.io/
• https://github.com/cosmostation

CosmosJS - Cosmos JavaScript Library

https://github.com/cosmostation/cosmosjs

Analysis:

• Talks to the Cosmos SDK REST server.
• We don't use the REST interface at all, as we have our GQL endpoint.
• Not much code or supporting tests. Different supported message types are just if-else statements (https://github.com/cosmostation/cosmosjs/blob/master/src/index.js#L118).
• Doesn't seem very useful in its current state.

Cosmostation Wallet Apps (Android & iOS)

https://github.com/cosmostation/cosmostation-mobile

Analysis:

• Not much documentation.
• Might be a good candidate to fork and change.

Keystation

• An end-to-end encrypted key manager for decentralized applications and networks built with the Cosmos SDK.
• What Keystation does is allow you to store your mnemonic phrase in a secure location for a more convenient way to sign and broadcast your transactions.
• Keystation is a decentralized keychain-based authenticator that DOES NOT require any installation. User keys are securely stored in the web browser Keychain, allowing for users to conveniently sign transactions for networks and decentralized applications built with the Cosmos SDK. Keystation can be used as a secure and convenient authentication and key management tool for web login, decentralized exchanges, decentralized applications, and various services built with the Cosmos SDK.

Analysis:

• We should look into this for our own wallet/signing impl.

Web Wallet

https://wallet.cosmostation.io/

• Web wallet with Ledger integration.
• Uses https://github.com/cosmostation/keystation for Tx signing.
• Wallet Guide.

Features

• Send tokens
• Delegate to validators
• Broadcast raw Tx

Analysis:

• Might be a good candidate to fork and change.

Mintscan

https://www.mintscan.io/

• Cosmos Block Explorer.

Analysis:

• Would be useful to reuse/fork for our chain, but doesn't seem to be open source.
