liquidity-staking-module

The purpose of this repository is to develop and release a new set of staking, distrbution and slashing modules for the Cosmos Hub that are compatible with cosmos-sdk v0.45.16-ics and cosmos-sdk v0.47.x. We'll be making simultaneous releases for both cosmos-sdk flavors, and won't be maintaining the sdk v0.46.x flavor unless there's a clear need to do so.

Liquid Staking design

This repo represents an opinionated design for adding liquid staking to the Cosmos SDK.

There are a few core goals.

1. Staked assets should be able to converted into liquid staked assets without unbonding.
2. The smallest change set possible on the existing staking, slashing and distrbution modules.
3. Assets are expected to be minimally fungible. Assets have a denom of "cosmosvaloperxxxx[recordId]". Record ID is a pointer to a non fungible asset that recieves the rewards from the tokenized stake.
4. Governance rights remain with the validator. Validators vote with the full voting power of all staked assets (including those made liquid), but liquid staked assets cannot vote (cannot override the validator).

Typical user flow.

1. Alice bonds 500 ATOM to iqlusion.io
2. Alice executes MsgTokenizeShares for the 500_000_000uatom and 500_000_000cosmosvaloper1xxxx42 in return.
3. Alice does an OTC deal with Bob for 250_000_000cosmosvaloper1xxxx42 assets.
4. Bob exectutes MsgRedeemTokensforShares for 250_000_000cosmosvaloper1xxxx42 which now becomes a delegation of 250atom to iqlusion.
5. While the shares were tokenized, TokenizedShareRecord 42 is recieving the full 500 atom of rewards minus iqlusion's commission.
6. Once Bob redeems his tokens for shares, now TokenizedShareRecord 42 will only recieve 250 atoms worth of rewards.
7. Alice can execute MsgWithdrawTokenizeShareRecordReward pass these rewards back to Alice's account.

Hypothetical user flow with refungiblization

This flow requires an integration with CosmWasm (or Interchain Security) that is not part of this repo at this time.

1. Alice bonds 500 ATOM to iqlusion.io
2. Alice executes MsgTokenizeShares for the 500_000_000uatom and 500_000_000cosmosvaloper1xxxx42 in return.
3. There is a staking DAO contract in cosmwasm that is willing to accept tokenizedshares from iqlusion.
4. Alice excutes a multimsg sending 500_000_000cosmosvaloper1xxxx42 and MsgTransferTokenizeShareRecord to the address of the Staking DAO contract.
5. The Staking contract queries the state to see shares to atom ratio for iqlusion and the pending rewards in the share record.
6. Alice recieve 500_000_000ustatom from the staking dao contract.

Testnet

This work should soon be live on the cosmos hub testnet.
