# Bonding \[Deprecated]

{% hint style="danger" %}
Bonding OHM was deprecated due to the Pyth network delisting LBGT price oracle, rendering immutable Bonding contracts unusable. Since then, bonding was upgraded into [Vesting](/arbero/vesting.md).

## Arbera Bonding: OHM & brOHM-brarBERO LPs

Arbera introduces a novel liquidity bonding mechanism that allows users to accelerate their **arBERO** vesting by contributing valuable counterparty liquidity, specifically in the form of **OHM**, which will get converted into brOHM-brarBERO LP. This structure not only deepens Protocol-Owned Liquidity (POL) but aligns incentives across stakeholders by offering fast-tracked access to premium rewards.

***

### Overview

The bonding mechanism allows users to:

* Convert `oBERO` into `arBERO` on a 90-day linear vesting schedule.
* Accelerate arBERO access by bonding `OHM` that would be routed into **brOHM-brarBERO liquidity**.
* Generate Protocol-Owned Liquidity that earns yield, boosts Arbera's voting power, and strengthens arBERO emissions.

***

### How It Works

#### 1. Start arBERO Vesting

Users deposit `oBERO` and receive `arBERO` vested linearly over 90 days.

* Example:

  Deposit `1,000 oBERO` → Receive `1,000 arBERO` over 3 months.

  (At $0.50 per oBERO and $2 per arBERO, this is a 4x premium locked behind vesting.)

***

#### 2. Bond OHM to Early Unlock arBERO

To fast-track access to arBERO, users can bond `OHM` and contribute it to Arbera’s POL via the `brOHM-brarBERO` LP.

* On deposit:
  * Dollar value of OHM is calculated using the OHM oracle by Pyth.
  * The OHM is sent to Arbera to zap it into brOHM-brarBERO LP.
* A 7-day cooldown begins from the moment OHM is bonded.
* After 7 days user has to unlock the dollar value plus a 10% bonus:
  * Eg. by depositing $100 in OHM, user receives $110 worth of bonus after 7 days.

***

#### 3. Fast Claim arBERO After Cooldown

After the 7-day lock expires, the user can unlock the bonus and execute a Fast arBERO Claim, withdrawing from their existing vesting position using the bonded liquidity as justification.

* Fast Claim Value:

  The user can claim arBERO worth up to the combined value of deposited OHM and oBERO, plus the 10% bonus on deposited OHM value.

### Example Flow

Assumptions:

* oBERO price: <mark style="color:yellow;">`$0.50`</mark>
* arBERO price: <mark style="color:yellow;">`$2.00`</mark>
* OHM price: <mark style="color:yellow;">`$20`</mark>
* arBERO is minted by oBERO 1:1

1. **User Deposits:**
   * <mark style="color:red;">`1,000 oBERO`</mark> → Worth $500
   * Begins 90-day vesting of <mark style="color:green;">`1,000 arBERO`</mark>
2. **User Bonds:**
   * <mark style="color:red;">`5 OHM`</mark> → Worth $100
   * Triggers 7-day timer
3. **User unlocks Bonus (after 7 Days):**
   * User unlocks <mark style="color:green;">`$110 Bonus`</mark> ($100 of deposited OHM value + 10% bonus)
4. **User fast claims arBERO**

* User can use <mark style="color:red;">`$110 Bonus`</mark> to fast claim <mark style="color:green;">`73.33`</mark> arBERO:
  * arBERO Premium Value is <mark style="color:yellow;">`$2 - $0.5 = $1.5`</mark>
  * User can claim <mark style="color:yellow;">`Bonus / Premium Value`</mark>
  * <mark style="color:yellow;">`$110 / $1.5 = 73.33`</mark> arBERO = <mark style="color:green;">`$146.66`</mark>
* User fast claimed arBERO worth <mark style="color:green;">`$146.66`</mark>, which includes:
  * <mark style="color:red;">`$36.66`</mark> of underlying oBERO (<mark style="color:yellow;">`73.33 * $0.5`</mark>)
  * <mark style="color:red;">`$100`</mark> in bonded OHM
  * <mark style="color:green;">`$10`</mark> of Bonus Profit
* User exercised 10% profit over his bonded OHM value.

### Why This Matters

* Accelerates Incentives: Users can front-load their arBERO access in return for deepening Arbera’s POL.
* Strengthens Liquidity: Bonded OHM is converted into `brOHM-brarBERO` LPs, expanding depth and stability.
* Premium Yield: With arBERO trading at a premium and earning boosted rewards, the mechanism remains economically attractive while aligned with long-term protocol health.
* No BGT Required: This mechanism operates independently of Berachain’s PoL (Proof of Liquidity) or BGT emissions. When combined in the future, it sets the stage for ultimate rewards vaults.

### Security

#### Audit

BondingConverter and ArberoOracle were audited by CDSecurity, nonetheless no audit can guarantee bug-free business logic.

#### Oracles

Bonding and bonus calculations are based on the custom oracles, combining Pyth prices and TWAP Uniswap oracles, to prevent JIT manipulation of prices.

* OHM price is derived as EMA from the Pyth oracle.
* LBGT price is derived as EMA from the Pyth oracle.
* oBERO price is derived as a two price points average of around -1h, and -5m from the tx execution, based on the BERO price from the main BERO-HONEY LP.
* arBERO price is derived as a 1h TWAP from brarBERO-brLBGT LP
