Credex Protocol Skill

Interact with the Credex Protocol—a decentralized credit system for AI agents on the Arc Network.

Usage

Base Directory: {baseDir} (the directory containing this SKILL.md) Run all commands from the project root: cd {baseDir} npx ts-node scripts/client.ts <command> [args] # Borrower commands npx ts-node scripts/lp.ts <command> [args] # LP commands Output Format: All scripts return JSON for machine readability. Parse the output to extract fields like creditLimit, txHash, debt, etc.

Client Commands (Borrower)

Script: scripts/client.ts Run as: npx ts-node scripts/client.ts <command> [args]

status

Check credit status for an agent. Usage: npx ts-node scripts/client.ts status <address> Args: address (optional): Wallet address. Defaults to WALLET_PRIVATE_KEY address. Returns: JSON { "creditLimit": "100.000000", "principal": "5.000000", "interest": "0.050000", "debt": "5.050000", "availableCredit": "95.000000", "active": true, "frozen": false } Action: Use availableCredit to check if sufficient funds before calling borrow.

borrow

Borrow USDC from the pool. Usage: npx ts-node scripts/client.ts borrow <amount> Args: amount (required): USDC amount as decimal string (e.g., "5.0"). Returns: JSON { "success": true, "txHash": "0x...", "borrowed": "5.000000", "newDebt": "5.000000", "availableCredit": "95.000000" } Fails if: amount > availableCredit. Check status first.

repay

Repay debt to the pool. Usage: npx ts-node scripts/client.ts repay <amount|all> Args: amount: Specific USDC amount to repay (e.g., "5.0"). all: Calculates total debt + 1% buffer and repays fully. The contract caps at actual debt owed. Returns: JSON { "success": true, "txHash": "0x...", "repaid": "5.050000", "remainingDebt": "0.000000", "newCreditLimit": "110.000000" } Note: Repayments pay interest first, then principal. Each successful repayment increases credit limit by 10%.

bridge

Bridge USDC between Arc Testnet and Base Sepolia. Usage: npx ts-node scripts/client.ts bridge <amount> <from> <to> Args: amount: USDC amount (e.g., "10.0"). from: Source chain (arc or base). to: Destination chain (arc or base). Returns: JSON { "success": true, "amount": "10.000000", "from": "Arc_Testnet", "to": "Base_Sepolia", "estimatedArrival": "5-10 minutes" } Fails if: from === to. Chains must be different.

balance

Check wallet balance on both chains. Usage: npx ts-node scripts/client.ts balance Returns: JSON { "arc": "50.000000", "base": "25.000000", "total": "75.000000" }

LP Commands (Liquidity Provider)

Script: scripts/lp.ts Run as: npx ts-node scripts/lp.ts <command> [args]

pool-status

Check overall pool health and metrics. Usage: npx ts-node scripts/lp.ts pool-status Returns: JSON { "totalAssets": "1000.000000", "totalLiquidity": "800.000000", "totalDebt": "200.000000", "totalShares": "950.000000", "sharePrice": "1.052631", "utilizationPercent": 20 }

deposit

Deposit USDC to receive LP shares. Usage: npx ts-node scripts/lp.ts deposit <amount> Args: amount: USDC to deposit (e.g., "100.0"). Returns: JSON { "success": true, "txHash": "0x...", "deposited": "100.000000", "sharesReceived": "95.000000", "totalShares": "95.000000" }

withdraw

Burn LP shares to withdraw USDC. Usage: npx ts-node scripts/lp.ts withdraw <shares|all> Args: shares: Number of shares to burn (e.g., "50.0"). all: Withdraw maximum possible based on available liquidity. Returns: JSON { "success": true, "txHash": "0x...", "sharesBurned": "50.000000", "usdcReceived": "52.631579", "remainingShares": "45.000000" } Note: Withdrawal may be capped if liquidity is fully utilized (all USDC lent out).

lp-balance

Check LP position for an address. Usage: npx ts-node scripts/lp.ts lp-balance [address] Returns: JSON { "shares": "95.000000", "value": "100.000000" }

Interest Accrual

Rate: 0.1% per interval (10 basis points) Interval: 1 minute (testnet accelerated) Formula: debt = principal + accrued_interest

Credit Limit Growth

After each repayment: newLimit = currentLimit × 1.10 Maximum: 10,000 USDC.

Available Credit

availableCredit = creditLimit - principal Interest does NOT reduce borrowing power—only principal.

Share Price (LP)

sharePrice = totalAssets / totalShares Where totalAssets = liquidity + outstandingDebt.

Borrower Flow

1. Check status → npx ts-node scripts/client.ts status 2. Borrow → npx ts-node scripts/client.ts borrow 5 3. Use funds → (perform task on Arc or bridge to Base) 4. Bridge back → npx ts-node scripts/client.ts bridge 5 base arc 5. Repay → npx ts-node scripts/client.ts repay all 6. Verify growth → npx ts-node scripts/client.ts status (limit increased!)

LP Flow

1. Check pool → npx ts-node scripts/lp.ts pool-status 2. Deposit → npx ts-node scripts/lp.ts deposit 100 3. Monitor → npx ts-node scripts/lp.ts lp-balance 4. Withdraw → npx ts-node scripts/lp.ts withdraw all
