Komodo (KMD) RPC client

A RPC client for Komodo (KMD), made in Rust. In the future, you can use this library to create Rust apps that communicate with Komodo blockchains. Since Crypto Conditions is supported in all Komodo assetchains, dApps can be created through this crate. Or at least, that is my goal for this.

With credits to the coblox team's Rust BTC RPC client.

This is a work in progress!

todo:

  • implement all API calls
  • argument Address into type
  • handle empty responses (setaccount)
  • improve error handling Client
  • find redeemScript in previous transactions (if any)
  • make sensible use of references in arguments
  • use Into<String> as argument for String types
  • get rid of needing AddressList for single address in parameter
  • define own Chain if needed assetchain isn't in enum
  • properly expose arguments / types
  • handle special case: wildcard "*" in fromaddresses, z_mergetoaddress
  • supply Client with manual RPC credentials
  • struct Unspent contains account in response, which is deprecated. Need to circumvent
  • listaddressgroupings returns an array with 3 different types, for each distinct address. how to fix in serde
  • add helper functions to several types
    • a selection of utxos upon entering an amount to address_utxos

This wrapper aims to:

  • be stateless, i.e. a thin layer. It's up to the app using this library to maintain state.

Features

  • Convert an utxolist retrieved through getaddressutxos to inputs in createrawtransaction
  • Automatically fetches KMD / Assetchain parameters from config file on Win, MacOS and Ubuntu/Debian

Currently supported calls

Below is a list of RPC calls in this Rust client as of KMDversion 0.3.3b

Notes

  • valueSat and valueZat are omitted from getrawtransaction and decoderawtransaction, respectively
  • Several network RPCs return no response from komodod. These RPCs are unsupported until further notice, being:
    • addnode
    • clearbanned
    • z_importkey
    • z_importviewingkey
    • z_importwallet
    • importaddress
    • importwallet
  • Sapling does not support z_exportviewingkey, or viewing keys in general, yet
  • RPC arguments checked before actual request:
    • address in address parameter is valid (basic length check for now)
  • sendtoaddress returns a transaction id that is little-endian, which is reversed from what you see on the explorer. Call be_hex_string() on the TransactionId type and you get the big-endian txid.
    • The transaction id that is deserialized will always be little-endian.
