Method

This dashboard takes a dive into bAsset market cap for bLUNA and bETH that is locked as collateral on Anchor.
I present an approach in my investigation where I determine:

• deposit(lock_collateral) and withdraw(unlock_collateral) amounts on Anchor

• net locked collateral amounts on Anchor: deposit - withdraw

• daily average price of bAssets by using terra.oracle_prices table

• market cap of bAssets that are locked on Anchor: net locked collateral amounts×average price

• bond and unbond amount of bLUNA

• total amounts(supply) of bLUNA: mint(bond)-burn(unbond)

• market cap of bAssets: total supply×average price

• Note: dashboard is created in 2022-03-23

Conclusion for bLUNA

As of March 23, 2022, it was found that:

• total supply of bLUNA is around 83M. by Avg price of bLuna on 23 March, marketCap of bLuna is around 7.82 B$.
• around 63M bLuna is locked on Anchor. by Avg price of bLuna on 23 March, locked marketCap of bLuna is around 5.94 B$.

Introduction

The Anchor protocol defines a money market between a lender, looking to earn stable yields on their stablecoins, and a borrower, looking to borrow stablecoins on stakeable assets. To borrow stablecoins, the borrower locks up Bonded Assets (bAssets) as collateral, and borrows stablecoins below the protocol-defined borrowing ratio. The diversified stream of staking rewards accruing to the global pool of collateral then gets converted to stablecoin, and then conferred to the lender in the form of a stable yield.
so Anchor is structured to provide depositors with:

• High, stable deposit yields powered by rewards of bAsset collaterals
• Instant withdrawals through pooled lending of stablecoin deposits
• Principal protection via liquidation of loans in risk of undercollateralization

About Bonded Assets (bAssets)

bAssets are liquid, tokenized representations of staked (bonded) assets in a PoS blockchain. They allow stakers to gain liquidity over their staked assets, enabling the locked value in staked assets to be utilized in financial applications such as Anchor.
bAsset tokens are an entitlement of the underlying staked asset position, where staking rewards are distributed to its holders.

Conclusion for bETH

As of March 23, 2022, it was found that:

• total supply of bETH is around 466k and marketCap of bETH is 1.46B$.
• around 444K bETH is locked on Anchor. by Avg price of bETH on 23 March, locked amount of bETH is around 1.318 B$

This linear graph shows daily mint and burn amounts of bLUNA; also it shows daily amounts of bLUNA that are locked and unlocked as collateral on Anchor.

The growth of total bonded LUNA and collateral amount of bLUNA which is on Anchor, are shown in the above area chart.

In the next chart, by use of the daily USD price of bLUNA, we are going to determine daily changes of marketCap.

76% of the bAsset market cap for bLUNA is locked as collateral on Anchor

With an overview of the extraterrestrial website transactions and finding sample transactions, we see that the rest of bLuna is held in the following cases:

• nexus vault
• Kujira pool

so, now we gonna continue with bLUNA.

In the next chart, by use of the daily USD price of bETH, we are going to determine daily changes of collateral marketcap of bETH

95% of the bAsset market cap for bETH is locked as collateral on Anchor

so, what about the rest 5%? With an overview of the extraterrestrial website transactions and finding sample transactions, it seems some of bEth is on nexus vault and kuji pool.

The growth of collateral amount of bETH which is on Anchor is shown in the above area chart.

In order to calculate collateral%, I bring total supply and market cap of bETH from extraterrestrial website
