What is Ribbon Finance (RBN) token?

By Katelyn James | October 9, 2021

Ribbon Finance is a new protocol that helps users access crypto structured products for DeFi. It combines options, futures, and fixed income to improve a portfolio’s risk-return profile.

Here you can find the product descriptions and outgoing links to the different communication channels if you want to contribute.

Core Products

Theta Vault

Theta Vault, which is a yield-focused strategy on ETH and WBTC. The vault earns yield on its deposits by running a weekly automated options selling strategy. The vault reinvests the yield earned back into the strategy, effectively compounding the yields for depositors over time.

The Theta Vaults run two options strategies to generate yields:

Covered call – Vault writes out of the money-covered calls.

Put selling – Vault writes out of the money puts.

Theta Vault Yearn

Currently, funds held in Theta Vaults do not generate any yield, aside from writing options. Every Friday, the vault converts 100% of its USDC balance into yvUSDC by depositing USDC into the Yearn USDC yVault. This helps depositors gain exposure to the yield generated from Yearn on top of the options strategy.

What are Theta Vaults?

Theta Vaults use the Vault terminology because it stems from the idea of depositing your assets into a vault and earning a yield on them, set-and-forget.

Users can simply deposit their assets into a smart contract and will automatically start running a specific options strategy. This alleviates a majority of the gas problems by socializing the gas costs across all the vault depositors. Instead of doing 3–4 transactions per week per user, the vault will do 3–4 transactions per week for thousands of users at once. This makes the user experience of using these Theta Vaults extremely straightforward and relatively cheap — deposit, wait for yields, and withdraw.

What is a Covered Call strategy?

The covered call strategy is a unique options strategy where you earn yield for selling the potential upside of an asset. For example, if you are willing to give up the potential upside of ETH going above $25k by the end of the year, you can get paid 2% in yield for selling a $25k call option. This is over 10x the yield you can earn by supplying ETH on Compound.

In the unlikely case that ETH goes to $30k, you would have given up $5k, but you are still tremendously up in USD terms — it is a win-win scenario for you because you only risk getting exercised when ETH absolutely moons.

Strike Selection and Expiry

To further reduce the risk of our options getting exercised, we can sell call options that expire sooner rather than later, because of how difficult it is to predict how ETH could perform over a longer time frame. Our initial vaults will sell weekly call options, meaning we can adjust our expectation of ETH’s price on a weekly basis. This also has the nice side effect of letting us compound our premiums more frequently.

Secondly, we need to select strike prices that are far enough from today’s spot price to reduce the risk of exercise. Our current methodology for strike selection and backtests shows that we only get exercised less than 5% of the time from Jan 2020 to today, even throughout the entire run up of ETH from $80 to $2000. We will publish a follow-up blog post about our strike selection methodology in detail.

Technical Architecture

Theta Vaults in its present design relies on Opyn oTokens. oTokens are ERC20 token representations of an options contract, where each of them have a strike price and expiry. Owning oTokens is functionally equivalent to owning an options contract. This gives the oToken holder the right to redeem some amount of the underlying asset if the strike price is hit.

In order to run an options-writing strategy, the Vault needs to be able to mint and short oTokens. The Vault uses the users’ deposited funds to lock collateral into Opyn + mint oTokens, then sells them for a premium. The Vault’s collateral will be locked until the expiry of the oToken. This collateral is used to pay off oToken holders in the case that the options expire in the money.

To facilitate the week-by-week operations of Theta Vaults, there is a privileged role called the Manager. The Manager is responsible for:

Selecting the parameters of the oToken to mint i.e. strike price and expiry.

Signing oToken sales OTC on behalf of the Theta Vault

Theta Vault Options Sale

Theta Vault mints oTokens a) The manager selects an oToken to mint based on the parameters of strike price and expiry. b) Vault uses deposited funds to lock collateral into Opyn protocol c) Vault mints oToken and holds onto these oTokens

Initiating oToken trade a) Manager and market makers decide on a price to sell the oTokens for (off-chain) b) Manager signs an Airswap order that exchanges the oTokens for WETH on behalf of the Theta Vault b) Manager sends the signed order to a market maker (off-chain)

Completing oToken trade a) Market maker counter-signs the order and posts the trade on the blockchain b) The swap is completed, Vault receives premium in WETH whereas the market maker receives the oTokens

The net result of this process is that the Vaults should receive premiums in return for writing the oTokens. This will mean that the Vault’s balance will expand over time as premiums are collected and compounded.

Participating in Open Auctions

Open Auctions are a batch auction conducted on the Gnosis Auction platform to sell off options that are minted by Theta Vault.

A batch auction means that there is only one clearing price.

Using an auction allows for price discovery on-chain, to ensure the options sale process is decentralized.

Max Supply: 1,000,000,000 RBN token

Circulating Supply: 46,799,623.03 RBN
