我有小广播，你要听我说：小姐姐辛苦翻译分享，心疼小姐姐的转载总可以注明来路吧！！如遇币豪们，文章下面有小姐姐的打赏地址，收基于ERC-20的各种币，一个都不嫌弃哦！
7 SYNOPSIS
• Enabling Lending, Leveraged Margin Trading and Short Selling on a Single Protocol
- Non-rent seeking, publicly accessible, decentralized and trust-independent
- Compatible with all ERC20 tokens
- Publicly accessible smart contracts for enhanced interoperability
• Decentralized Lending
- Borrower pledges collateral, eligible for 2.5 times leverage
- Lender defines terms of loan - amount, interest, expiration period - in offer object, with ECDSA signature
- ecrecover function verifies signature, Smart Contract checks validity of loan, Lender’s funding account. Funds then credited to
Trader’s Margin Account
• Shared Lending Pool
- All loan offers are recorded and available to every Relayer on the protocol
- Irrespective of which Relayer records the loan offer, it is accessible by all Relayers
- A Shared Lending pool has far-reaching applications, beyond just margin trading
• Margin Trading
- A Margin Trader can deposit not just one kind of collateral in a token of his choice, but multiple kinds of ERC20-based tokens at
the same time, in the same margin account.
- Stakes LST when opening a Margin Account. This is refunded if he closes his positions and repays the loan, and is paid as
bounty to Wranglers if the account reaches liquidation level.
- On successful trade and meeting loan terms, Margin Trader may withdraw collateral and profits.
• Interface and Bookkeeping
- Relayers maintain offer books and order books off-chain
- Relayers can offer APIs to facilitate programmatic access to offer books
- With access to the entire lending pool, Relayers can maintain liquidity and create an interface that encourages patronage.
- Relayers are incentivized with the native token LST. They are paid when loans are closed.
• Margin-Level Monitoring and Loan Repayment
- Wranglers are Lendroid-exclusive players, incentivized to monitor Margin Accounts and close loans.
- Wranglers monitor margin accounts off-chain, ‘wrangle’ accounts at liquidation level, repay Lender’s loan, take over trader’s
options and collateral.
- Loan repayment is an incentivized aspect of the protocol; encourages symbiosis among the players.
- Loan is closed either by the Trader after successful trade, by Wranglers after taking over Margin
Account at liquidation level. In the unlikely case neither trader or Wrangler repay, the lender calls in the loan, withdraws
collateral and trade positions.
• Lendroid Auction
- When a Wrangler identifies a terminal margin account, the claim is verified by the smart contract. If ratified, the Wrangler is
awarded a bounty (part of the loan offer object, deposited by the Lender) and the triggerAuction function is called.
- The Lendroid auction is not winner take all. The trader’s collateral and positions are taken over, but not by any single Wrangler.
Every Wrangler chooses to repay a small portion of total outstanding loan and his bid would be proportionately considered.
• Lendroid Support Token
- Powers the utility layer of the protocol.
- LSTs are baked into the protocol for the service providers – Relayers and Wranglers.
- Incentivizes participation on the protocol. For example, without a single LST, a user is authorized to monitor margin accounts
and if she identifies an account at liquidation level, stands to earn LSTs
- Envisioned as a vehicle to enable code upgrades, Network parameters, and Supported assets.
七 概要
.启动贷款，杠杆保证金交易和单一协议卖空
- 非寻租，可公开，分步的和信任独立
- 兼容所有ERC20令牌
- 可公开访问的智能合约提高互操作性
.分步式贷款
- 借款人承诺提供抵押品，有资格获得2.5倍的杠杆
- 贷款人定义贷款条款 - 金额，利息，到期期限 - 提供对象，并签署ECDSA
-ecrecover功能验证签名，智能合同检查贷款的有效性，贷款人的资金帐户。 然后资金存入交易者的保证金账户
.共享的贷款池
- 所有的贷款要约都记录下来，并提供给协议上的每个中继者
- 无论哪一位中继者记录贷款要约，都可以被所有的中继者使用
- 共享贷款池具有深远的应用，不仅仅是保证金交易
•保证金交易
- 保证金交易者可以在同一保证金账户中存入不止一种类型的抵押品，而是可以同时存入多种基于ERC20的代币。
- 在开立保证金账户时支付利息。 如果他结清头寸并偿还贷款，这笔款项将被退还，如果账户达到清算水平，则作为奖金支付给牧马人。
- 成功的交易和符合贷款条件下，保证金交易者可以提取抵押品和利润
•Interface and Bookkeeping –•界面和簿记
- 中继者维护提供要约和链下的订单
- 中继者可以提供API来促进程序化访问以提供要约
- 通过访问整个贷款池，中继者可以保持流动性，并创建一个鼓励赞助的接口。
- 使用本地令牌LST（代币）激励中继者。 当贷款被关闭时，他们被支付。
•保证金水平监测和贷款偿还
- 牧马人是Lendroid独家角色，激励监控保证金账户和关闭贷款。
- 贷款还款是协议的激励方面; 鼓励玩家之间的共生。
- 交易者成功交易后，由牧马人在清算水平接管保证金账户后关闭贷款。 在不大可能的情况下，交易者或牧马人都不会偿还，贷款人要求贷款，撤销抵押品和交易头寸。
•Lendroid拍卖
- 当牧马人识别一个终端保证金账户时，该声明由智能合约进行验证。 如果批准，牧马人被授予赏金（由贷方存放的贷款提供对象的一部分），并触发拍卖功能。
-Lendroid拍卖不是赢家通吃。 交易者的抵押品和仓位被接管，但不是任何一个牧马人。
每个牧马人选择偿还总贷款的一小部分，他的出价将按比例考虑。
•Lendroid代币
- 为协议的实用层提供动力。
- LST被植入了中继者和牧马人服务提供商的协议里。
- 激励参与协议。 例如，如果没有LST，用户有权监控保证金账户，如果她在清算级别识别账户，则可以获得LST
- 作为启用代码升级，网络参数和支持资产的工具。
