## Background

In an exciting move to kick off the Acala 2.0 Exodus Upgrade and celebrate the launch of the LSTFi-centered Universal Asset Hub, we are thrilled to introduce our liquidity mining program. This program is designed to empower participants, providing them with the opportunity to receive substantial rewards, including up to 20 million ACA per month in ACA staking, boosted LCDOT and DOT staking via the Euphrates DApp, as well as participation in select liquidity pairs on Acala Swap and various ecosystem DApps.

The [sentiment vote](https://voting.opensquare.io/space/acala/proposal/QmZ1jmUtWN4wFBncS2556gGo79p2T89qVqSNzWZF9hN49w) to approve the general direction of the liquidity mining program has been approved on 16th Sep. This vote in particular is specifically for incentive allocation for ACA Staking and ACA liquidity on Acala Swap. Other sub-programs will be detailed in separate proposals.

## ACA Staking Sub-Program

At the heart of this program is the aim to align stakeholders, Acala ecosystem participants, protocol functionalities, network infrastructures, ecosystem growth, and ACA utility within the Acala Network. By doing so, we seek to optimize network growth and sustainability while enhancing ACA’s role as a fundamental utility.

- Target ACA Staking APR: 10%
- Target Staking Rate: 30% to 50%

APR will vary depending on market conditions and participation. This proposal covers the initial two weeks’ incentive, and further incentive adjustments will be proposed in the following week.

## ACA Liquidity Pair Sub-Program

We understand the importance of fostering liquidity within the Acala ecosystem. To achieve this, we’re introducing long-term incentivized liquidity pools on Acala Swap, powered by ACA. The first pair is ACA-USDCet with the following parameters

- Target APR: 10% - 16%
- Target liquidity $5 - 10M

APR will vary depending on market conditions and participation. This proposal covers the initial two weeks’ incentive, and further incentive adjustments will be proposed in the following week.
Sub-programs of other liquidity pairs will be available in separate proposals.

## Background

In an exciting move to kick off the Acala 2.0 Exodus Upgrade and celebrate the launch of the LSTFi-centered Universal Asset Hub, we are thrilled to introduce our liquidity mining program. This program is designed to empower participants, providing them with the opportunity to receive substantial rewards, including up to 20 million ACA per month in ACA staking, boosted LCDOT and DOT staking via the Euphrates DApp, as well as participation in select liquidity pairs on Acala Swap and various ecosystem DApps.

The sentiment vote to approve the general direction of the liquidity mining program has been approved on 16th Sep. This vote in particular is specifically for incentive allocation for Euphrates DApp LCDOT staking. Other sub-programs will be detailed in separate proposals.

Euphrates Liquidity DApp
Euphrates is the liquidity DApp that offers stakers and liquidity providers of Liquid Staking Tokens (LSTs) the opportunity to earn boosted rewards. Participants can claim ACA tokens as well as rewards from participating project tokens e.g. TAI (Taiga Protocol) with minimal effort. 

The first phase of Euphrates launch will accept LCDOT (and later DOT) for tDOT and LDOT pools. LCDOT in Euphrates will be automatically converted into DOT after the Acala lease period concludes and staked into tDOT or LDOT, ensuring users won’t miss out on staking rewards.

LCDOT Staking Target Launch APR: A target launch APR of 35–55% is set for LCDOT staking (excluding DOT staking rewards), which will be adjusted depends on demand and LCDOT staked. This proposal covers the initial two weeks incentive, and further incentive adjustments will be proposed in the following week.

Runtime upgrade - Update Substrate/Cumulus/Polkadot version to v0.9.40

## Background
Following the passing of the vote for the generation of the Exodus Plan, this is to propose aSEED (Acala) I setting risk parameters of aUSD including stop aUSD minting, liquidation etc in preparation for aUSD conversion to aSEED (Acala). Below are the risk parameters to be adjusted: 
+ Liquidation Ratio = 0%
+ Debt Ceiling = 0
+ Stability Fee = 0
+ Liquidity Penalty = 0

+ [General direction vote](https://voting.opensquare.io/space/acala/proposal/QmXFw8DZbX5wDFeD1kQtFDy8tmE4FKEir7tZVqe9vCqBTb)

aSEED (Acala) I Setting risk parameters of aUSD

## Background
https://acala.discourse.group/t/acala-risk-parameter-change-proposal-may-2023/2096

## Proposal
The following suggestion is proposed to optimize for risk management for Acala.

+ Decrease Debt Ceiling of DOT from 50M to 20M
+ Decrease Debt Ceiling of LDOT from 5M to 2M
+ Decrease Debt Ceiling of LCDOT from 6M to 2M
+ Decrease Debt Ceiling of ACA from 6M to 1.5M

Risk parameters are best adjusted according to market conditions to balance insolvencies, liquidations, and capital efficiency. A lower debt ceiling helps mitigate the risk associated with excessive debt exposure and enable the protocol to remain solvent and resilient in volatile market conditions.
