PandaDAO-VeToken

PandaDAO VeToken smart contracts

Introduction

1. The sources of voting power for DAO governance include: token holders, veToken holders, work group, leader. Work group voting weight is 15%, leader is 5%, and the remaining 80% is allocated according to the number of token or veToken held.
2. Exchange rate is stable(veToken:locked token = 1:1) and token holders are able to stake or claim at any time. It's temporarily decided that dividends are shared out once a year. Multi-signer can decide whether to share out the dividend in advance.
3. Dividend weights emission is at certain ratio. The minimum emission time period is one block.

Roles:

• Owner: accessible to gnosis safe contract who has admin role
• Staker: accessible to public who is able to stake Panda token for voting power as well as earn dividends from DAO treasury.

Main Operations:

• Owner:

1. Emergency Operations: Turn on or off claiming or staking function
2. Claim other mistaken tokens from other systems

• Staker:

1. Deposit Panda token for a certain address which could in turn get same amount of veToken
2. Withdraw Panda token for burning same amount of veToken

$PANDA Claim流程方案

方案流程：

实现要点：

Back-end: 分红周期快到的时候，根据收益模型计算出所有账户的收益MerkleTree模型，并把MerkleRoot给Contract；后面根据Front-end请求返回账户的分红代币数Amount与MerkleProof；收到Front-end发送的ClaimNotify将该账户置位，记录该账户已经领取

Contract：分红周期快到的时候，多签钱包将代币打到Claim合约，合约所有者重新设置MerkleRoot；用户该周期领取奖励之后，合约记录已领取；

Front-end: 提供wallet登录，向Back-end发送Claim请求，向Contract发送Claim调用，Claim完成之后向Back-end发送已Claim请求。
