Architecture

架构

  • Read ops (
    get-markets
    ,
    get-position
    ) → direct
    eth_call
    via public RPC; no confirmation needed
  • Write ops (
    supply
    ,
    borrow
    ,
    withdraw
    ,
    repay
    ,
    claim-rewards
    ) → after user confirmation, submits via
    onchainos wallet contract-call
  • 读操作(
    get-markets
    get-position
    )→ 通过公共RPC直接发起
    eth_call
    ,无需确认
  • 写操作(
    supply
    borrow
    withdraw
    repay
    claim-rewards
    )→ 经用户确认后,通过
    onchainos wallet contract-call
    提交交易

Pre-flight Checks

前置检查

Before executing any write command, verify:
  1. Binary installed:
    compound-v3 --version
    — if not found, install the plugin via the OKX plugin store
  2. Wallet connected:
    onchainos wallet status
    — confirm wallet is logged in and active address is set
  3. Chain supported: target chain must be one of Ethereum (1), Base (8453), Arbitrum (42161), Polygon (137)
If the wallet is not connected, output:
Please connect your wallet first: run `onchainos wallet login`
执行任何写命令前,请验证:
  1. 二进制文件已安装:运行
    compound-v3 --version
    ——如果找不到命令,请通过OKX插件商店安装本插件
  2. 钱包已连接:运行
    onchainos wallet status
    ——确认钱包已登录且已设置活跃地址
  3. 链已支持:目标链必须是Ethereum (1)、Base (8453)、Arbitrum (42161)、Polygon (137)之一
如果钱包未连接,输出:
Please connect your wallet first: run `onchainos wallet login`

Key Concepts

核心概念

supply = repay when debt exists Supplying the base asset (e.g. USDC) automatically repays any outstanding debt first. The plugin always shows current borrow balance and explains this behavior.
borrow = withdraw base asset In Compound V3,
Comet.withdraw(base_asset, amount)
creates a borrow position when there is insufficient supply balance. The plugin distinguishes borrow from regular withdraw by checking
borrowBalanceOf
.
repay overflow protection Never use
uint256.max
for repay. The plugin reads
borrowBalanceOf
and uses
min(borrow_balance, wallet_balance)
to prevent revert when accrued interest exceeds wallet balance.
withdraw requires zero debt Attempting to withdraw collateral while in debt will revert. The plugin checks
borrowBalanceOf
and blocks the withdraw with a clear error message if debt is outstanding.
存款=存在债务时还款 存入基础资产(如USDC)会自动优先偿还所有未偿还债务,插件始终会展示当前借款余额并解释该行为。
借款=提取基础资产 在Compound V3中,当存款余额不足时,
Comet.withdraw(base_asset, amount)
会创建借款仓位,插件会通过检查
borrowBalanceOf
区分借款和常规提取操作。
还款溢出保护 切勿使用
uint256.max
作为还款金额,插件会读取
borrowBalanceOf
并使用
min(借款余额, 钱包余额)
来防止应计利息超过钱包余额时出现交易回滚。
提取要求零债务 负债时尝试提取抵押品会导致交易回滚,插件会检查
borrowBalanceOf
,如果存在未偿还债务会阻止提取并返回清晰的错误信息。

Dry-Run Mode

试运行模式

All write operations support
--dry-run
. In dry-run mode:
  • No transactions are submitted
  • The expected calldata, steps, and amounts are returned as JSON
  • Use this to preview before asking for user confirmation
所有写操作都支持
--dry-run
参数。在试运行模式下:
  • 不会提交任何交易
  • 预期的调用数据、步骤和金额会以JSON格式返回
  • 在请求用户确认前可使用该模式预览操作

Do NOT use for

不适用场景

  • Non-Compound protocols (Aave, Morpho, Spark, etc.)
  • DEX swaps or token exchanges (use a swap plugin instead)
  • Yield tokenization (use Pendle plugin instead)
  • Bridging assets between chains
  • Staking or liquid staking (use Lido or similar plugins)

  • 非Compound协议(Aave、Morpho、Spark等)
  • DEX兑换或代币交易(请使用兑换类插件)
  • 收益代币化(请使用Pendle插件)
  • 跨链资产桥接
  • 质押或流动性质押(请使用Lido或同类插件)
