name: cetus-aggregator description: A Claude Code skill for working with the Cetus Aggregator SDK to execute optimized swaps across multiple Sui DEXs. Use this skill when you need to perform token swaps, find optimal routes across 30+ DEXs, execute gas-optimized transactions, or configure overlay fees on Sui blockchain.

Cetus Aggregator SDK Skill

A Claude Code skill for working with the Cetus Aggregator SDK to execute optimized swaps across multiple Sui DEXs. This skill provides comprehensive tools for multi-DEX routing, price discovery, and gas-optimized swap execution using the @cetusprotocol/aggregator-sdk library.

Instructions

Use this skill when you need to execute token swaps on the Sui blockchain. Includes:

1. SDK Initialization: Configure environment, wallet, and RPC connection
2. Multi-DEX Routing: Find optimal price routes across 30+ DEXs
3. Swap Execution: Execute fast swaps or manual route swaps
4. Slippage Protection: Configure slippage tolerance to protect transactions
5. Gas Optimization: Dynamic gas management and budget settings
6. Protocol Fees: Configure overlay fees and recipient addresses
7. Error Handling: Comprehensive error handling and market condition validation

Quick Start

// Initialize SDK
import { AggregatorClient, Env } from '@cetusprotocol/aggregator-sdk'
import { SuiClient } from '@mysten/sui/client'
import { Ed25519Keypair } from '@mysten/sui/keypairs/ed25519'

const mnemonics: string = process.env.MNEMONICS!;
const i = 0;
const path = `m/44'/784'/${i}'/0'/0'`;
const keypair = Ed25519Keypair.deriveKeypair(mnemonics, path);
const wallet = keypair.toSuiAddress();

const suiClient = new SuiClient({
    url: process.env.RPC!,
});

const client = new AggregatorClient({
    signer: wallet,
    client: suiClient,
    env: Env.Mainnet,
});

Usage Examples

Basic Swap Operations

// Find optimal routes
const routers = await client.findRouters({
  from: "0x2::sui::SUI",
  target: "0x06864a6f921804860930db6ddbe2e16acdf8504495ea7481637a1c8b9a8fe54b::cetus::CETUS",
  amount: new BN(1000000000),
  byAmountIn: true,
  providers: ["CETUS", "KRIYA", "AFTERMATH"]
});

// Execute fast swap
const txb = new Transaction();
await client.fastRouterSwap({
  router: routers,
  txb,
  slippage: 0.01,
  refreshAllCoins: true,
});

const result = await client.signAndExecuteTransaction(txb, keypair);
console.log("Swap executed:", result);

Query Swap Function

import { Transaction, coinWithBalance } from '@mysten/sui/transactions'
import BN from 'bn.js'
import { bcs } from '@mysten/sui/bcs'

export const querySwap = async (client: AggregatorClient, keypair: Ed25519Keypair, from: string, target: string, amount: string, amountOut: string) => {
    let router: any = null;
    let txb: any = null;
    let targetCoin: any = null;

    try {
        const wallet = keypair.toSuiAddress();

        const amountIn = new BN(amount);
        router = await client.findRouters({
            from,
            target,
            amount: amountIn,
            byAmountIn: true,
            providers: ["CETUS","SCALLOP","AFTERMATH","FLOWXV3","AFSUI","STEAMM","VOLO","KRIYAV3","KRIYA","ALPHAFI","FLOWX","BLUEMOVE","DEEPBOOKV3","BLUEFIN","HAEDAL","TURBOS","SPRINGSUI","STEAMM","METASTABLE","HAWAL","OBRIC"]
        });

        if (router === null) {
            return;
        }

        const amountOutput = router.amountOut;

        if (amountOutput.lt(new BN(amountOut))) {
            console.log("Trade condition not met");
            return;
        }

        txb = new Transaction();

        targetCoin = await client.routerSwap({
            router,
            txb,
            inputCoin: coinWithBalance({ type: from, balance: BigInt(amount) }),
            slippage: 0.01,
        });

        txb.moveCall({
            package: "0xe450c157978058fc23078941924ad91bfe3022db6243ffa432f7209ad5bc9889",
            module: "utils",
            function: "check_coin_threshold",
            arguments: [
                targetCoin,
                txb.pure(bcs.U64.serialize(BigInt(amountOut))),
            ],
            typeArguments: [
                target,
            ],
        });
        txb.transferObjects([targetCoin], wallet);

        txb.setSender(wallet);
        txb.setGasBudget(1_000000000);

        const result = await client.client.signAndExecuteTransaction({ transaction: txb, signer: keypair });
        console.log("result", result);

    } catch (error) {
        console.log("querySwap error:", error);
    } finally {
        router = null;
        txb = null;
        targetCoin = null;

        if (global.gc) {
            global.gc();
        }
    }
}

Provider Management

import { getAllProviders, getProvidersExcluding, getProvidersIncluding } from '@cetusprotocol/aggregator-sdk'

// Get all supported providers
const allProviders = getAllProviders()

// Get providers excluding specific ones
const filteredProviders = getProvidersExcluding(["CETUS", "KRIYA"])

// Get only specific providers
const specificProviders = getProvidersIncluding(["TURBOS", "AFTERMATH"])

The aggregator supports 30+ DEXs, including:

• CETUS, KRIYA (V2/V3), FLOWX (V2/V3), TURBOS, AFTERMATH
• HAEDAL, VOLO, AFSUI, BLUEMOVE, DEEPBOOKV3
• SCALLOP, SUILEND, BLUEFIN, HAEDALPMM, ALPHAFI
• SPRINGSUI, STEAMM, METASTABLE, OBRIC, HAWAL
• MOMENTUM, STEAMM_OMM, STEAMM_OMM_V2, MAGMA, SEVENK

Common Token Types

// Mainnet token types
const SUI = "0x2::sui::SUI"
const USDC = "0xdba34672e30cb065b1f93e3ab55318768fd6fef66c15942c9f7cb846e2f900e7::usdc::USDC"
const USDT = "0x375f70cf2ae4c00bf37117d0c85a2c71545e6ee05c4a5c7d282cd66a4504b068::usdt::USDT"
const CETUS = "0x06864a6f921804860930db6ddbe2e16acdf8504495ea7481637a1c8b9a8fe54b::cetus::CETUS"
const AFSUI = "0xf325ce1300e8dac124071d3152c5c5ee6174914f8bc2161e88329cf579246efc::afsui::AFSUI"
const HA_SUI = "0xbde4ba4c2e274a60ce15c1cfff9e5c42e41654ac8b6d906a57efa4bd3c29f47d::hasui::HA_SUI"

Best Practices

Route Validation

// Always check for null routes
const routers = await client.findRouters({
  from: "0x2::sui::SUI",
  target: "0x...::cetus::CETUS",
  amount: new BN(1000000000),
  byAmountIn: true,
});

if (routers) {
  // Execute swap
} else {
  console.log("No routes found");
}

Slippage Management

// Use appropriate slippage based on market conditions
const slippage = 0.01; // 1% for stable pairs
const slippage = 0.05; // 5% for volatile pairs

Gas Optimization

// Set appropriate gas budget
txb.setGasBudget(1_000000000); // 1 SUI for complex swaps
txb.setGasBudget(500000000);   // 0.5 SUI for simple swaps

Error Handling

try {
  const routers = await client.findRouters({
    from: "0x2::sui::SUI",
    target: "0x...::cetus::CETUS",
    amount: new BN(1000000000),
    byAmountIn: true,
  });

  if (routers) {
    const txb = new Transaction();
    await client.fastRouterSwap({
      router: routers,
      txb,
      slippage: 0.01,
      refreshAllCoins: true,
    });

    const result = await client.signAndExecuteTransaction(txb, keypair);
  } else {
    console.log("No routes found");
  }
} catch (error) {
  console.error("Swap execution failed:", error);
}

Complete Workflow Example

import { AggregatorClient, Env } from '@cetusprotocol/aggregator-sdk'
import { SuiClient } from '@mysten/sui/client'
import { Ed25519Keypair } from '@mysten/sui/keypairs/ed25519'
import { Transaction } from '@mysten/sui/transactions'
import BN from 'bn.js'

async function executeOptimizedSwap() {
  // 1. Initialize client
  const mnemonics: string = process.env.MNEMONICS!;
  const keypair = Ed25519Keypair.deriveKeypair(mnemonics, `m/44'/784'/0'/0'/0'`);

  const suiClient = new SuiClient({ url: process.env.RPC! });
  const client = new AggregatorClient({
    signer: keypair.toSuiAddress(),
    client: suiClient,
    env: Env.Mainnet,
  });

  // 2. Find optimal routes
  const routers = await client.findRouters({
    from: "0x2::sui::SUI",
    target: "0x06864a6f921804860930db6ddbe2e16acdf8504495ea7481637a1c8b9a8fe54b::cetus::CETUS",
    amount: new BN(1000000000),
    byAmountIn: true,
    providers: ["CETUS", "KRIYA", "AFTERMATH"]
  });

  if (!routers) {
    console.log("No routes available");
    return;
  }

  // 3. Execute swap
  const txb = new Transaction();
  await client.fastRouterSwap({
    router: routers,
    txb,
    slippage: 0.01,
    refreshAllCoins: true,
  });

  const result = await client.signAndExecuteTransaction(txb, keypair);
  console.log("Swap completed:", result.digest);

  return result;
}
