Token launches on Robinhood Chain can become interesting when launch mechanics include a temporary snipe tax.

In this tutorial, I'll show the basic architecture behind a Pons V2 Bundler Bot and how to build a simple one-wallet launchAndBuy implementation.

This is an educational/research project designed to help developers understand how automated on-chain trading systems work.

What We're Building

The basic workflow is:

Pons Factory
     ↓
Check canLaunch()
     ↓
Read launch configuration
     ↓
Read current snipe tax
     ↓
Build launchAndBuy()
     ↓
Simulate transaction
     ↓
Sign & execute

The bot can provide commands such as:

pnpm pons index

pnpm pons can-launch 0xYourWallet

pnpm pons tax \
  --token 0xToken \
  --wallet 0xWallet

pnpm pons preview \
  --config examples/launch.json

pnpm pons launch \
  --config examples/launch.json

Understanding the Snipe Tax

One of the interesting parts of Pons V2 is the temporary launch tax.

The contract exposes:

currentSnipeTaxBps

where the value is represented in basis points.

For example:

100 bps   = 1%
1000 bps  = 10%
9900 bps  = 99%

The tax decreases as the launch progresses.

This means that buying immediately after launch can be very different from buying later.

The interesting part is the relationship between the launch transaction and its recipient.

With launchAndBuy, the launch and initial purchase can happen together, allowing us to study how the launch contract treats the initial recipient compared with another wallet.

For example:

LaunchAndBuy recipient
        ↓
      0 bps

Random wallet
        ↓
   ~9900 bps

The exact behavior should always be verified against the current Pons V2 contracts.

Building the Bot

The project can be organized into a few simple modules:

src/
├── cli.ts
├── launch.ts
└── tax.ts

examples/
└── launch.json

cli.ts

Handles commands such as:

pons index
pons can-launch
pons tax
pons preview
pons launch

launch.ts

Handles:

• Factory configuration
• canLaunch
• launchAndBuy
• Transaction construction
• Transaction simulation

tax.ts

Reads:

currentSnipeTaxBps

for a specific token and wallet.

Transaction Safety

One important detail is msg.value.

The launch transaction may require the launch fee plus the initial buy amount:

msg.value =
    launch fee
  + first buy

Before sending the transaction, the bot should:

1. Validate the configuration.
2. Check canLaunch.
3. Calculate the required value.
4. Simulate the transaction.
5. Only then sign and broadcast.

I also recommend making execution explicit:

pnpm pons launch --config examples/launch.json

for a dry run, and:

pnpm pons launch \
  --config examples/launch.json \
  --live

when you intentionally want to send the transaction.

Security

Never put private keys directly into source code.

Use a local .env:

PONSBOT_PRIVATE_KEY=0x...
RPC_URL=https://rpc.mainnet.chain.robinhood.com

and add .env to .gitignore.

For testing, use a dedicated wallet with only the funds required for the experiment.

What's Next?

The one-wallet implementation is only the starting point.

A larger system could add:

• Multi-wallet coordination
• Real-time launch monitoring
• Transaction tracking
• Telegram notifications
• Risk filters
• Wallet management
• Execution monitoring

But I recommend understanding the single-wallet flow first. Once you understand the contract calls, tax calculation, transaction value, and execution flow, the larger architecture becomes much easier to build.

Source Code

I've collected my Robinhood Chain trading-bot research, strategies, and development projects here:

[Robinhood Trading Bot System — GitHub]

The repository covers different Robinhood Chain bot concepts, including sniper bots, copy trading, token launch research, liquidity strategies, arbitrage, and other automated trading ideas.
