2020-03-25 LSWG Call 6
- Anchor (presentation by Do Kwon (Terra Money))
- Staking product that allows user to hold stablecoins and earn staking rewards
- Background staking derivatives
- 1. Tradable staking positions
- 2. Using staked collateral in defi applications
- Terra looked at principal protected notes in defi space:
- E.g. Dai Savings Rate (DSR)
- Interest of these products normally fluctuate based on speculation demand
- Driving force is opening/closing of CDPs => volatility
- Rely on third party participation
- E.g. keepers in maker that have to liquidate CDPs
- How could you build sth completely programmatically without third party participation?
- Staking derivative for LUNA, bLUNA (representing staked position minus cost of bonding (max. commission rate + slashing))
- bLUNA tries to be fungible among validators (by abstracting slashing and commission rates)
- Staking reward cash flows in stablecoin (from Terra payments network tx)
- Idea is to get ppl to participate in staking and get exposure to staking rewards without being required to hold volatile principal (the staking token)
- What is the level of overcollateralization?
- Less than in a protocol with third party intervention (in comparison to liquidator model) because they have on-chain swap mechanism between stablecoins and staking token
- Explanation of swap mechanism
- Terra validators vote on price feeds (oracle)
- mechanism
- Terra to Terra stablecoin charges 25bps
- Terra stablecoins to Luna similar to Uniswap
- Swap spreads that can go up to 100% depending on usage
- bLUNA could only be one type of collateral, multi-collateral model should be possible
- Insurance fund to make sure positions stay overcollateralized in a high volatile/many liquidations environment
- Unslashed (insurance protocol, focused on slashing protection first)
- Slides (see Github issue)
- Risk derivatives, transfer risks from slashing to third party
- Insurance marketplace (cover buyers and investors that provide collateral and will get premiums)
- Combining insurance tokens with staking derivatives tokens you can get a fungible, slashing risk free staking token
- Examples what you could do with such a token
- Leverage (via a CDP system like Maker)
- Lending (via a money market like Compound
- Short selling (built on lending market)
- Opportunities w/ slashing insurance
- Less centralization risk (bc no separate trading pairs for each validator)
- Allows more differentiation between validators (insurance market creates an assessment of market risk)
- Making money out of a security exploit
- Validator exit scamming delegators by buying a lot of covers and then double-signing
- How much collateral needs to be put up?
- Fully collateralized, example:
- $1m ATOM position => $50k collateral (5% slashing max.)
- Account for price movements in ATOM,...
- Collateral will be used for multiple things (e.g. lending on a money market, could also be using liquid ATOMs)
- There is a risk management layer in which risk underwriters can manage their collateral)
- Similar to traditional Insurance-linked securities
- In 3-4 months for v1
- Integration with protocols works on a protocol-by-protocol basis
- Other insurance products Unslashed is looking at
- Counterparty risks (e.g. liquidation in DeFi)
- How will claims be validated?
- Slashing is on-chain, no need to process claims, data needs to arrive, money goes to people holding the insurance token
