Architecture

Source code: https://github.com/skylavis-sky/onchainos-plugins/tree/main/compound-v3 (binary built from commit 6882d08d)

  • 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

Pre-flight Checks

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`

Commands

get-markets — View market statistics

compound-v3 [--chain 8453] [--market usdc] get-markets

Reads utilization, supply APR, borrow APR, total supply, and total borrow directly from the Comet contract. No wallet needed.

Display only these fields from output: market name, utilization (%), supply APR (%), borrow APR (%), total supply (USD), total borrow (USD). Do NOT render raw contract output verbatim.

get-position — View account position

compound-v3 [--chain 8453] [--market usdc] get-position [--wallet 0x...] [--collateral-asset 0x...]

Returns supply balance, borrow balance, and whether the account is collateralized. Read-only; no confirmation needed.

Display only these fields from output: wallet address, supply balance (token units + USD), borrow balance (token units + USD), collateralized status (true/false). Do NOT render raw contract output verbatim.

supply — Supply collateral or base asset

Supplying base asset (e.g. USDC) when debt exists will automatically repay debt first.

# Preview (dry-run)
compound-v3 --chain 8453 --market usdc --dry-run supply \
  --asset 0x4200000000000000000000000000000000000006 \
  --amount 100000000000000000

# Execute
compound-v3 --chain 8453 --market usdc supply \
  --asset 0x4200000000000000000000000000000000000006 \
  --amount 100000000000000000 \
  --from 0xYourWallet

Execution flow:

  1. Run with --dry-run to preview the approve + supply steps
  2. Ask user to confirm the supply amount, asset, and market before proceeding
  3. Execute ERC-20 approve: onchainos wallet contract-call → token.approve(comet, amount)
  4. Wait 3 seconds (nonce safety)
  5. Execute supply: onchainos wallet contract-call → Comet.supply(asset, amount)
  6. Report approve txHash, supply txHash, and updated supply balance

borrow — Borrow base asset

Borrow is implemented as Comet.withdraw(base_asset, amount). No ERC-20 approve required. Collateral must be supplied first.

# Preview (dry-run)
compound-v3 --chain 8453 --market usdc --dry-run borrow --amount 100000000

# Execute
compound-v3 --chain 8453 --market usdc borrow --amount 100000000 --from 0xYourWallet

Execution flow:

  1. Pre-check: isBorrowCollateralized must be true; amount must be ≥ baseBorrowMin
  2. Run with --dry-run to preview
  3. Ask user to confirm the borrow amount and ensure they understand debt accrues interest
  4. Execute: onchainos wallet contract-call → Comet.withdraw(base_asset, amount)
  5. Report txHash and updated borrow balance

repay — Repay borrowed base asset

Repay uses Comet.supply(base_asset, amount). The plugin reads borrowBalanceOf and uses min(borrow, wallet_balance) to avoid overflow revert.

# Preview repay-all (dry-run)
compound-v3 --chain 8453 --market usdc --dry-run repay

# Execute repay-all
compound-v3 --chain 8453 --market usdc repay --from 0xYourWallet

# Execute partial repay
compound-v3 --chain 8453 --market usdc repay --amount 50000000 --from 0xYourWallet

Execution flow:

  1. Read current borrowBalanceOf and wallet token balance
  2. Run with --dry-run to preview
  3. Ask user to confirm the repay amount before proceeding
  4. Execute ERC-20 approve: onchainos wallet contract-call → token.approve(comet, amount)
  5. Wait 3 seconds
  6. Execute repay: onchainos wallet contract-call → Comet.supply(base_asset, repay_amount)
  7. Report approve txHash, repay txHash, and remaining debt

withdraw — Withdraw supplied collateral

Withdraw requires zero outstanding debt. The plugin enforces this with a pre-check.

# Preview (dry-run)
compound-v3 --chain 8453 --market usdc --dry-run withdraw \
  --asset 0x4200000000000000000000000000000000000006 \
  --amount 100000000000000000

# Execute
compound-v3 --chain 8453 --market usdc withdraw \
  --asset 0x4200000000000000000000000000000000000006 \
  --amount 100000000000000000 \
  --from 0xYourWallet

Execution flow:

  1. Pre-check: borrowBalanceOf must be 0. If debt exists, prompt user to repay first.
  2. Run with --dry-run to preview
  3. Ask user to confirm the withdrawal before proceeding
  4. Execute: onchainos wallet contract-call → Comet.withdraw(asset, amount)
  5. Report txHash

claim-rewards — Claim COMP rewards

Rewards are claimed via the CometRewards contract. The plugin checks getRewardOwed first — if zero, it returns a friendly message without submitting any transaction.

# Preview (dry-run)
compound-v3 --chain 1 --market usdc --dry-run claim-rewards

# Execute
compound-v3 --chain 1 --market usdc claim-rewards --from 0xYourWallet

Execution flow:

  1. Pre-check: call CometRewards.getRewardOwed(comet, wallet). If 0, return "No claimable rewards."
  2. Show reward amount to user
  3. Ask user to confirm before claiming
  4. Execute: onchainos wallet contract-call → CometRewards.claimTo(comet, wallet, wallet, true)
  5. Report txHash and confirmation

Key Concepts

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.

Dry-Run Mode

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

Do NOT use for

  • 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)

Error Responses

All commands return structured JSON. On error:

{"ok": false, "error": "human-readable error message"}
