[Epic]: Osmosis <> BTC Phase 1

[keruch]

Summary

This epic outlines the Phase 1 implementation of integrating the Bifrost Protocol with the Osmosis blockchain to enable cross-chain asset swaps.

Problem Definition

This integration aims to leverage Bifrost's bridging capabilities to connect Osmosis with other blockchains, starting with the BTC network, to facilitate decentralized cross-chain asset transfers.

Work Breakdown

Scaffold x/bridge module:

• params:
  • Allowed source_chains []string
  • Allowed asset on source chain []string
• Create MsgMint:
  • Message MsgMint { sender: String, source_chain: String, dst_address: String, asset_name: String, amount: BigInt }
  • Create func that checks if sender is allowed to execute mint.
  • Check if not Shutdown
  • If allowed mint using token factory a coin with denom: MsgMint.source_chain + MsgMint.asset_name, amount: amount
• Create MsgBurn:
  • Message MsgBurn { sender: String, coin: Coin, dst_address: String}
  • Decompose coin.denom to -> source_chain and asset_name
  • Burn the asset
• Create MsgUpdateSigners
  • Can only be executed by Gov
  • Updates the valset allowed to sign
• Creat MsgShutdown:
  • Can be called by the current signers, same as MsgMint
  • Specifies source_chain to shutdown

it is so sensible, I could go blind from looking at this
