How to build a Pons Family Token Bundler Bot on Robinhood Chain

#robinhood #bundler #bot #architecture

Token launches can involve multiple wallets, transactions, and execution steps.

When these operations are performed manually, managing wallets, nonces, gas, transaction ordering, and confirmations can become difficult.

This is where a Pons Family Token Bundler Bot can be useful as an infrastructure and research project.

Robinhood chain builder bot

Pons is a platform for launching and exploring fixed-supply tokens on Robinhood Chain. Transactions are submitted through the user's wallet, and Pons does not custody user assets.

The goal of this project is to study how multiple wallets and transactions can be coordinated through an automated execution pipeline.

Research focus: transaction coordination, wallet management, signing, execution, and monitoring. The system is not intended to manipulate token markets or mislead market participants.

Architecture

The basic architecture looks like this:

Pons Launch
     ↓
Wallet Manager
     ↓
Transaction Builder
     ↓
Validation
     ↓
Signing Engine
     ↓
Execution Queue
     ↓
Robinhood Chain
     ↓
Confirmation
Enter fullscreen mode Exit fullscreen mode

Each component has a specific responsibility.

Robinhood Chain Setup

Robinhood Chain is an Arbitrum Layer-2 built on Ethereum and uses ETH as its native gas token. The official documentation lists:

Mainnet Chain ID: 4663
Testnet Chain ID: 46630
Enter fullscreen mode Exit fullscreen mode

The documentation also provides RPC and WebSocket endpoints for blockchain applications.

For a bundler, WebSocket connectivity can be useful when monitoring transaction state in real time.

1. Wallet Manager

The wallet manager maintains the wallets used by the workflow.

{
  "wallets": [
    {
      "id": "wallet_01",
      "address": "0x..."
    },
    {
      "id": "wallet_02",
      "address": "0x..."
    }
  ]
}
Enter fullscreen mode Exit fullscreen mode

The system can track:

  • Wallet address
  • ETH balance
  • Nonce
  • Transaction status
  • Transaction history

Private keys should never be hard-coded.

For production systems, use secure key-management or signing infrastructure.

2. Transaction Builder

The transaction builder converts the launch plan into transactions.

A simplified EVM transaction contains:

transaction = {
    "to": contract_address,
    "value": value,
    "data": calldata,
    "nonce": nonce,
    "chainId": 4663
}
Enter fullscreen mode Exit fullscreen mode

A useful pipeline is:

Build
  ↓
Validate
  ↓
Sign
  ↓
Queue
  ↓
Broadcast
Enter fullscreen mode Exit fullscreen mode

Keeping these stages separate makes debugging and testing much easier.

3. Nonce Management

Every EVM wallet has its own transaction sequence.

For example:

Wallet A
Nonce 10
Nonce 11
Nonce 12

Wallet B
Nonce 5
Nonce 6
Nonce 7
Enter fullscreen mode Exit fullscreen mode

The bundler therefore needs to maintain nonce state per wallet.

wallet_state = {
    "0xWalletA": {
        "next_nonce": 10
    },
    "0xWalletB": {
        "next_nonce": 5
    }
}
Enter fullscreen mode Exit fullscreen mode

Incorrect nonce handling can result in rejected or stuck transactions.

4. Transaction Ordering

Some transactions depend on previous operations.

For example:

Deploy Token
     ↓
Prepare Operation
     ↓
Execute Operation
Enter fullscreen mode Exit fullscreen mode

The execution engine should explicitly understand these dependencies.

Independent transactions can be handled separately, while dependent transactions remain sequential.

This is an important difference between simply sending transactions and building a transaction-orchestration system.

5. Signing

After validation, transactions are signed.

Transaction
     ↓
Validation
     ↓
Signer
     ↓
Signed Transaction
Enter fullscreen mode Exit fullscreen mode

The signing layer should be isolated from the rest of the application.

This makes it possible to use different signing methods later, such as a secure key-management service or hardware-backed signer.

6. Execution Queue

The execution queue controls which transactions are ready to broadcast.

A queue item might look like:

{
  "id": "tx_001",
  "wallet": "wallet_01",
  "nonce": 10,
  "status": "pending"
}
Enter fullscreen mode Exit fullscreen mode

Typical states are:

PENDING
   ↓
SIGNED
   ↓
SUBMITTED
   ↓
CONFIRMED
Enter fullscreen mode Exit fullscreen mode

If something fails:

SUBMITTED
     ↓
FAILED
     ↓
RETRY / STOP
Enter fullscreen mode Exit fullscreen mode

This provides visibility into the entire execution process.

7. Confirmation Tracking

Broadcasting a transaction doesn't mean the workflow is finished.

The bot should monitor the transaction until the required confirmation state is reached.

Transaction Submitted
        ↓
Transaction Hash
        ↓
Receipt
        ↓
Block
        ↓
Confirmation
Enter fullscreen mode Exit fullscreen mode

Useful data to store includes:

Transaction hash
Block number
Status
Gas used
Timestamp
Enter fullscreen mode Exit fullscreen mode

This also makes recovery easier if the bot restarts during a launch.

Handling Failures

Blockchain automation needs to expect failures.

Examples include:

  • Insufficient gas
  • Invalid nonce
  • RPC timeout
  • Contract revert
  • Invalid transaction data
  • Confirmation timeout
  • Network interruption

A simple failure handler could look like:

if transaction_failed:

    mark_failed(transaction)

    if retry_allowed(transaction):
        retry(transaction)
    else:
        stop_workflow()
Enter fullscreen mode Exit fullscreen mode

The important principle is:

Fail safely instead of continuing blindly.

Pons Family Launch Workflow

A simplified Pons-related workflow can be modeled as:

             Pons Launch
                  ↓
            Launch Plan
                  ↓
           Wallet Manager
                  ↓
        Transaction Builder
                  ↓
             Validation
                  ↓
           Signing Engine
                  ↓
          Execution Queue
                  ↓
          Robinhood Chain
                  ↓
        Confirmation Tracker
Enter fullscreen mode Exit fullscreen mode

The bundler becomes an orchestration layer between the launch configuration and blockchain execution.

Complete System

Putting the components together:

                         Pons Launch

                     │ Signing Engine  │
                     └────────┬────────┘
                              ↓
                     ┌─────────────────┐
                     │ Execution Queue │
                     └────────┬────────┘
                              ↓
                       Robinhood Chain
                              ↓
                     ┌─────────────────┐
                     │ Confirmation    │
                     │ Tracker         │
                     └─────────────────┘
Enter fullscreen mode Exit fullscreen mode

This architecture separates:

Wallet Management
Transaction Construction
Nonce Management
Validation
Signing
Execution
Confirmation
Enter fullscreen mode Exit fullscreen mode

Each component can then be tested independently.

Testing

Before using mainnet, test the complete system on Robinhood Chain testnet.

A practical workflow is:

Local Development
       ↓
Unit Tests
       ↓
Testnet
       ↓
Small Mainnet Test
       ↓
Production
Enter fullscreen mode Exit fullscreen mode

Test cases should include:

  • Multiple wallets
  • Sequential transactions
  • Nonce conflicts
  • Failed transactions
  • Insufficient gas
  • RPC failures
  • Confirmation timeouts
  • Application restarts
  • Recovery after failed execution

The goal is to make the system predictable before introducing real assets.

Final Thoughts

A Pons Family Token Bundler Bot is essentially a transaction-orchestration system.

The core workflow is:

Plan
 ↓
Manage Wallets
 ↓
Build Transactions
 ↓
Validate
 ↓
Sign
 ↓
Queue
 ↓
Execute
 ↓
Confirm
Enter fullscreen mode Exit fullscreen mode

The interesting engineering challenges are not just blockchain calls.

They include nonce management, transaction dependencies, signing security, execution queues, failure recovery, and confirmation tracking.

By separating these components, developers can build a clean foundation for researching automated token-launch workflows on Robinhood Chain.

The focus should remain on legitimate blockchain infrastructure and transaction coordination—not market manipulation or misleading activity.
