# Icepick

Icepick is a framework for rapidly developing applications to perform transfer
and staking cryptocurrency operations.

## Implementing a New Coin

Coins are implemented using the `icepick_coin::Coin` trait. Implementing the
trait should act as a "flow" for implementing the coin.

The crate will need the `clap` dependency for generating the CLI command and
the `icepick-coin` dependency for implementing the `Coin` trait.

`Coin` should be implemented on marker structs that can be easily placed in the
main Icepick program.

## Bitcoin

Bitcoin is a native coin, and does not require any kind of custom token support
atop an existing blockchain.

Possible routes to enable BTC transfer:

* `bitcoin` Rust module should support creating and signing transactions, as
  well as communicating with a Bitcoin node

## Ethereum

Ethereum is the native currency of the Ethereum blockchain. Ethereum supports
proof-of-stake, so staking needs to be enabled as well. The Ethereum blockchain
is also the host of many tokens, meaning Ethereum token transactions should
also be supported.

Possible routes to enable ETH and Ethereum Token transfer:

* Alloy, the Rust Ethereum project, should enable the necessary functionality

## Solana

Solana is a Rust-native coin and can be used to host tokens. Solana
incorporates proof-of-stake, so staking functionality is also required.

Possible routes to enable SOL and Solana Token transfer:

* Load Keyfork-derived key onto Ledger device
* Perform transaction using Solana SPL CLI to transfer tokens
  * `spl-token transfer --sign-only`
* `solana-client` Rust crate should have necessary functionality

## Pyth

PYTH is a token that can be traded on the Solana network. The token is like an
NFT that can have multiple amounts, so to transfer PYTH, you're basically just
transferring that amount of an NFT.

Possible routes to enable PYTH transfer:

* Load Keyfork-derived key onto Ledger device
* Perform transaction using Solana SPL CLI to transfer tokens
  * `spl-token transfer --sign-only`

## Stride (Token)

STRD is a coin using Inter-Blockchain Communication to interact with other
coins in the Cosmos ecosystem.

Possible routes to enable STRD transfer:

* Use `stride` to communicate with Stride
* Build CLI with `cosmrs` to communicate with Osmosis or Stride

## Ronin

Ronin uses the EVM on its own blockchain, meaning we can use the above
guidelines for Ethereum to connect.

Possible routes to enable Ronin transfer:

* `alloy`, in a similar manner to ETH

## Spacemesh

Spacemesh is a unique blockchain written in Go, but providing a Rust SDK. Proof
of stake doesn't seem to be supported, so staking would not be an option for
this blockchain.

Possible routes to enable Spacemesh transfer:

* Spacemesh Rust SDK crate
* Spacemesh Go SDK, ported to Rust
