CDPM Agent SDK Guide

Overview

This guide is for AI agents authorized to manage CDPM positions on behalf of users. Agents have limited permissions and operate within specific boundaries.

Agent Permission Model

What Agents CAN Do

Operation	Description
Add Liquidity	Add liquidity using PositionManager balance
Remove Liquidity	Remove liquidity and return to balance
Collect Fees	Collect fees from position (goes to fee bag)
Collect Rewards	Collect rewards (goes to fee bag)
Transfer Fee to Balance	Move fees from fee bag to balance
Scallop scallop_supply	Park idle balance into Scallop
Scallop scallop_redeem	Pull underlying back; yield fee deducted from interest portion
Kai SAV kai_supply	Park idle balance into a Kai Vault<T, YT>
Kai SAV kai_redeem	Pull underlying back via the strategy walk; same yield fee on interest

What Agents CANNOT Do

Operation	Reason
Withdraw Funds	Cannot move funds out of PositionManager
Close Position	Only owner can close
Authorize/Revoke Agents	Only owner can manage agents
Modify PositionManager	Cannot change configuration

Permission Check

function canAgentOperate(
  pm: PositionManager,
  agentAddress: string
): boolean {
  return pm.agents.includes(agentAddress);
}

// Example check
const { response: pm } = await client.getObject({ id: pmId, include: { content: true } });
const agents = pm?.content?.fields?.agents || [];
const isAuthorized = agents.includes(agentAddress);

Topics

Core Operations

• Agent Operations - Add/remove liquidity, collect fees, transfer fees
• Scallop Lending - Agent-driven scallop_supply / scallop_redeem (one tx.moveCall each); yield fee shares fee_house.fee_rate with Kai
• Kai SAV Lending - Agent-driven kai_supply / kai_redeem (one tx.moveCall each); yield fee shares fee_house.fee_rate with Scallop
• Automation Strategies - Auto-compounding, rebalancing, fee collection scheduler

Monitoring & Best Practices

• Event Monitoring - Subscribe to agent events
• Best Practices - Pre-operation checks, batch operations, gas optimization
• Security - Security checklist for agents

Reference

• Error Handling - Common agent errors and recovery strategies
• Constants - Package IDs and default thresholds

Calculations

For liquidity calculations, bin price math, position management, and fee calculations, use the cdpm-calculation skill with the Cetus DLMM SDK:

import { BinUtils, FeeUtils } from '@cetusprotocol/dlmm-sdk/utils'

// Agent-specific calculations
const qPrice = BinUtils.getQPriceFromId(binId, binStep)
const liquidity = BinUtils.getLiquidity(amountA, amountB, qPrice)
const binId = BinUtils.getBinIdFromPrice(price, binStep, true, decimalA, decimalB)
const positionCount = BinUtils.getPositionCount(lowerBinId, upperBinId)
const { amount_a, amount_b } = BinUtils.calculateOutByShare(bin, removeLiquidity)

// Agent strategy helper
function distributeLiquidity(totalA: string, totalB: string, bins: number[], binStep: number) {
  return bins.map(binId => {
    const qPrice = BinUtils.getQPriceFromId(binId, binStep)
    const amountA = (BigInt(totalA) / BigInt(bins.length)).toString()
    const amountB = (BigInt(totalB) / BigInt(bins.length)).toString()
    return { binId, amountA, amountB, liquidity: BinUtils.getLiquidity(amountA, amountB, qPrice) }
  })
}
