title: ‘FluxBeam Integration’ description: ‘Learn how to create and manage liquidity pools with FluxBeam’

​

Key Features

• Create new liquidity pools
• Support for native SOL and SPL tokens
• Automatic decimal handling
• LangChain tool integration
• Built-in slippage protection

​

Basic Usage

​

Creating a New Pool

import { PublicKey } from "@solana/web3.js";

const signature = await agent.fluxbeamCreatePool(
  new PublicKey("So11111111111111111111111111111111111111112"), // SOL
  1.5, // 1.5 SOL
  new PublicKey("EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v"), // USDC
  10, // 10 USDC
);

​

Input Parameters

​

Pool Creation Parameters

interface CreatePoolParams {
  token_a: PublicKey;      // First token mint address
  token_a_amount: number;   // Amount of first token
  token_b: PublicKey;      // Second token mint address
  token_b_amount: number;   // Amount of second token
}

​

LangChain Integration

​

Create Pool Tool

import { SolanaFluxbeamCreatePoolTool } from 'solana-agent-kit';

const createPoolTool = new SolanaFluxbeamCreatePoolTool(agent);

// Tool input format (JSON string):
const input = JSON.stringify({
  token_a: "So11111111111111111111111111111111111111112",
  token_a_amount: 1.5,
  token_b: "EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v",
  token_b_amount: 10
});

// Tool returns JSON response:
{
  status: "success",
  message: "Token pool created successfully",
  transaction: "signature...",
  token_a: "token_a_address",
  token_a_amount: 1.5,
  token_b: "token_b_address",
  token_b_amount: 10
}

​

Example Prompts

​

Creating Pools

"Create a new pool with 1.5 SOL and 10 USDC"
"Setup a liquidity pool using 100 USDC and 5 SOL"
"Create a new FluxBeam pool for SOL/USDC pair"

​

Error Handling

try {
  const signature = await agent.fluxbeamCreatePool(
    tokenA,
    amountA,
    tokenB,
    amountB
  );
} catch (error) {
  if (error.message.includes("insufficient funds")) {
    // Handle insufficient balance
  } else if (error.message.includes("invalid mint")) {
    // Handle invalid token address
  }
}

​

API Details

​

FluxBeam API

• Base URL: FLUXBEAM_BASE_URI
• Endpoint: /token_pools
• Method: POST
• Required fields: payer, token_a, token_b, token_a_amount, token_b_amount

​

Best Practices

1. Token Amount Handling
   • Input amounts in human-readable format (e.g., 1.5 SOL, not 1500000000 lamports)
   • The integration automatically handles decimal conversion
   • Always verify token decimals before submission
2. Token Address Validation
   • Use PublicKey class for token addresses
   • Verify token existence before pool creation
   • Handle native SOL cases appropriately
3. Transaction Signing
   • Transactions are automatically signed by the agent
   • Uses VersionedTransaction for compatibility
   • Includes retry logic for better reliability
4. Error Recovery
   • Implement proper error handling
   • Check for sufficient balances
   • Verify token approvals

​

Implementation Notes

1. Decimal Handling
   Copy

   // Example of how decimals are handled internally
   const scaledAmount = amount * Math.pow(10, decimals);
   

2. Native SOL Support
   Copy

   const isNativeSol = token.equals(TOKENS.SOL);
   const decimals = isNativeSol ? 9 : await getTokenDecimals(agent, token);
   

3. Transaction Processing
   Copy

   // Transaction is created, signed, and sent
   const transaction = VersionedTransaction.deserialize(TransactionBuf);
   transaction.sign([agent.wallet]);
   const signature = await agent.connection.sendRawTransaction(
     transaction.serialize(),
     {
       maxRetries: 3,
       skipPreflight: true,
     }
   );
   

​

Common Use Cases

1. Creating a SOL/USDC Pool
   Copy

   const signature = await agent.fluxbeamCreatePool(
     TOKENS.SOL,
     1.5,    // 1.5 SOL
     TOKENS.USDC,
     10      // 10 USDC
   );
   

2. Creating a Custom Token Pool
   Copy

   const signature = await agent.fluxbeamCreatePool(
     new PublicKey("custom_token_a"),
     100,
     new PublicKey("custom_token_b"),
     200
   );
