Building a Pons Trading Terminal on Robinhood Chain with TypeScript

#typescript #web3 #robinhood #tradingbot

A practical architecture for building a Pons trading terminal with market data, launch monitoring, token pages, order execution, risk management, portfolio tracking, and blockchain reconciliation.

A Pons trading terminal is more than a frontend dashboard.

The frontend displays the market, but the real system underneath has to handle:

Pons Launch Monitor
        ↓
Market Data
        ↓
Token State
        ↓
Trading Strategy
        ↓
Risk Engine
        ↓
Quote Engine
        ↓
Execution Engine
        ↓
Transaction Monitoring
        ↓
   Portfolio
        ↓
Reconciliation
Enter fullscreen mode Exit fullscreen mode

This article shows how I would structure a production-oriented Pons trading terminal on Robinhood Chain using TypeScript.

The design is intentionally modular so the same backend can later support:

Pons Sniper Bot
Pons Copy Trading Bot
Pons Bundler
Pons Launch Monitor
Pons Analytics
Enter fullscreen mode Exit fullscreen mode

What Is a Pons Trading Terminal?

A trading terminal brings market information and trading execution into one interface.

A basic version might only show:

Token
Price
Buy
Sell
Enter fullscreen mode Exit fullscreen mode

A real terminal needs much more:

Launches
Markets
Trading activity
Charts
Wallets
Orders
Risk
Positions
Portfolio
Transactions
Alerts
Enter fullscreen mode Exit fullscreen mode

A useful architecture is:

PONS TRADING TERMINAL
        ↓
┌─────────────────────┐
│     MARKET DATA     │
│                     │
│ • Launches          │
│ • Markets           │
│ • Trades            │
│ • Token State       │
└──────────┬──────────┘
           ↓
┌─────────────────────┐

└──────────┬──────────┘
           ↓
┌─────────────────────┐
│     RISK ENGINE     │

│ • Position Limits   │
│ • Exposure          │
│ • Slippage          │
│ • Gas Reserve       │
└──────────┬──────────┘
           ↓

│ • Transaction       │
└──────────┬──────────┘
           ↓
┌─────────────────────┐
│  ROBINHOOD CHAIN    │
│                     │
│ • Contracts         │
│ • Transactions      │
│ • Events            │
│ • Balances          │
└──────────┬──────────┘
           ↓
┌─────────────────────┐

│ • Tx State          │
│ • Balances          │
│ • Positions         │
│ • Portfolio         │
└─────────────────────┘
Enter fullscreen mode Exit fullscreen mode

This structure is deliberately vertical because large horizontal diagrams tend to become difficult to read on mobile.

Why Build a Pons Trading Terminal?

The terminal can become the central interface for several Pons products.

Pons Launch Monitor
        ↓
Pons Trading Terminal
        ↓
┌─────────────────────┐
│ Manual Trading      │
│ Pons Sniper         │
│ Pons Copy Trading   │
│ Pons Analytics      │
└─────────────────────┘
Enter fullscreen mode Exit fullscreen mode

Instead of building a separate execution system for every product, they can share:

Risk
Quote
Execution
Transactions
Portfolio
Reconciliation
Enter fullscreen mode Exit fullscreen mode

That reduces duplicated logic and makes the system easier to maintain.

Project Structure

A TypeScript implementation can be organized like this:

apps/
├── web/
└── api/

packages/
├── pons/
├── chain/
├── market-data/
├── execution/
├── risk/
├── portfolio/
├── alerts/
└── shared/
Enter fullscreen mode Exit fullscreen mode

The frontend can live in:

apps/web
Enter fullscreen mode Exit fullscreen mode

while the backend lives in:

apps/api
Enter fullscreen mode Exit fullscreen mode

The protocol-specific logic belongs in reusable packages rather than React components.

Frontend Architecture

For the frontend, a reasonable stack is:

Next.js
React
TypeScript
Tailwind CSS
TanStack Query
Lightweight Charts
WebSocket / SSE
Enter fullscreen mode Exit fullscreen mode

The frontend should be a consumer of backend state.

The browser should not become the blockchain execution engine.

A useful flow is:

Frontend
   ↓
Trading API
   ↓
Market / Risk / Execution Services
   ↓
Robinhood Chain
Enter fullscreen mode Exit fullscreen mode

Main Routes

The terminal can expose:

/
 /markets
 /markets/[token]
 /launches
 /trade
 /orders
 /portfolio
 /wallets
 /alerts
 /settings
Enter fullscreen mode Exit fullscreen mode

The most important page is:

/markets/[token]
Enter fullscreen mode Exit fullscreen mode

because that becomes the central trading workspace.

Main Trading Layout

The desktop terminal can use multiple panels, but the underlying information hierarchy should remain simple:

┌─────────────────────────┐
│ Header                  │
├─────────────────────────┤
│ Launches / Watchlist    │
├─────────────────────────┤
│ Token + Chart           │
├─────────────────────────┤
│ Recent Trades           │
├─────────────────────────┤
│ Order Preview           │
├─────────────────────────┤
│ Position / Portfolio    │
├─────────────────────────┤
│ Transaction Status      │
└─────────────────────────┘
Enter fullscreen mode Exit fullscreen mode

On desktop these sections can be displayed side-by-side.

On mobile they can stack vertically.

1. Pons Market Data Layer

The market-data service should own:

launches
tokens
trades
prices
pool state
curve state
Enter fullscreen mode Exit fullscreen mode

Create:

packages/market-data/
Enter fullscreen mode Exit fullscreen mode

A simple interface:

interface MarketDataService {
  getLaunches(): Promise<PonsLaunch[]>;
  getMarket(token: string): Promise<MarketState>;
  getTrades(token: string): Promise<Trade[]>;
  getPrice(token: string): Promise<PriceData>;
}
Enter fullscreen mode Exit fullscreen mode

The frontend should never need to know how these values are obtained.

2. Launch Monitor Integration

The terminal should reuse the Pons Launch Monitor.

Instead of:

Terminal
   ↓
new blockchain scanner
Enter fullscreen mode Exit fullscreen mode

use:

Pons Launch Monitor
        ↓
Event Stream
        ↓
Trading Terminal
Enter fullscreen mode Exit fullscreen mode

That gives the terminal access to:

new launches
token address
creator
protocol version
pool / curve
launch block
trading state
Enter fullscreen mode Exit fullscreen mode

This also allows the exact same event stream to feed a sniper bot.

3. Token Search

The terminal should support search by:

token address
token symbol
token name
creator address
Enter fullscreen mode Exit fullscreen mode

Example:

ABC
0x1234...
Pons v2
Active
Bonding Curve
Enter fullscreen mode Exit fullscreen mode

Always use the contract address as the canonical identity.

Names and symbols are metadata.

4. Token Detail Page

The token page should expose:

Token
Symbol
Address
Creator
Protocol Version
Trading Venue
Price
Volume
Recent Trades
Chart
Position
Order Panel
Transactions
Enter fullscreen mode Exit fullscreen mode

A normalized backend model might look like:

interface MarketState {
  tokenAddress: string;

  protocolVersion: "v1" | "v2";

  venue:
    | "PONS_POOL"
    | "PONS_CURVE"
    | "UNISWAP_V4";

  active: boolean;

  poolAddress?: string;
  curveAddress?: string;

  graduated?: boolean;
}
Enter fullscreen mode Exit fullscreen mode

The UI can then show:

Pons v2
Venue: Bonding Curve
Status: Active
Enter fullscreen mode Exit fullscreen mode

or:

Pons v2
Venue: Uniswap v4
Status: Graduated
Enter fullscreen mode Exit fullscreen mode

5. Trading Activity

A token page should display actual recent trades:

TIME       SIDE     PRICE      SIZE
12:41:02   BUY      ...        ...
12:40:58   BUY      ...        ...
12:40:51   SELL     ...        ...
Enter fullscreen mode Exit fullscreen mode

This comes from:

Blockchain
    ↓
Trade Indexer
    ↓
Database
    ↓
Trading API
    ↓
Frontend
Enter fullscreen mode Exit fullscreen mode

Do not fabricate trading activity.

If data is unavailable, say so.

6. Price Charts

A charting layer can use a library such as:

Lightweight Charts
Enter fullscreen mode Exit fullscreen mode

The backend can aggregate observed trade data into chart points.

Onchain Trades
      ↓
Aggregation
      ↓
Chart Data
      ↓
Frontend
Enter fullscreen mode Exit fullscreen mode

Possible intervals:

1m
5m
15m
1h
4h
1d
Enter fullscreen mode Exit fullscreen mode

Only display intervals supported by the available data.

7. Order Panel

The order panel should collect:

Side
Amount
Slippage
Wallet
Enter fullscreen mode Exit fullscreen mode

Example:

BUY / SELL

Amount
0.02 ETH

Slippage
1.0%

Wallet
0x123...
Enter fullscreen mode Exit fullscreen mode

But don't immediately submit.

Use:

Order
   ↓
Preview
   ↓
Risk
   ↓
Confirmation
   ↓
Execution
Enter fullscreen mode Exit fullscreen mode

8. Order Preview API

Create:

POST /api/orders/preview
Enter fullscreen mode Exit fullscreen mode

The response could look like:

interface OrderPreview {
  tokenAddress: string;

  side: "BUY" | "SELL";

  amountIn: bigint;

  expectedOut?: bigint;
  minOut?: bigint;

  slippageBps: number;

  estimatedGas?: bigint;

  currentExposure: bigint;
  resultingExposure: bigint;

  riskApproved: boolean;
  riskReason?: string;

  expiresAt: number;
}
Enter fullscreen mode Exit fullscreen mode

The frontend displays this before the user confirms.

9. Quote Expiration

Quotes should not remain valid forever.

For example:

Quote generated
     ↓
10 second lifetime
     ↓
Expired
Enter fullscreen mode Exit fullscreen mode

If a user confirms after expiry:

QUOTE EXPIRED

Refresh quote before execution.
Enter fullscreen mode Exit fullscreen mode

Never silently reuse a stale execution quote.

10. Risk Engine

Create:

packages/risk/
Enter fullscreen mode Exit fullscreen mode

The risk engine should check:

maximum position
maximum exposure
gas reserve
slippage
open positions
daily limits
Enter fullscreen mode Exit fullscreen mode

Example:

interface RiskResult {
  approved: boolean;
  reasons: string[];
}
Enter fullscreen mode Exit fullscreen mode

The actual execution flow is:

Order
  ↓
Quote
  ↓
Risk
  ↓
Execute
Enter fullscreen mode Exit fullscreen mode

Risk validation must run again immediately before live execution.

11. Position Sizing

Position sizing belongs in the backend.

For example:

Wallet Balance
      ↓
Gas Reserve
      ↓
Risk Budget
      ↓
Maximum Position
      ↓
Final Order Size
Enter fullscreen mode Exit fullscreen mode

This prevents the frontend from bypassing the user's configured limits.

12. Pons Execution Engine

The execution layer should be reusable by:

Manual Trading
Pons Sniper
Pons Copy Trading
Enter fullscreen mode Exit fullscreen mode

Architecture:

Trading Strategy
      ↓
Risk Engine
      ↓
Quote Engine
      ↓
Execution Controller
      ↓
Transaction Manager
      ↓
Pons
      ↓
Robinhood Chain
Enter fullscreen mode Exit fullscreen mode

Keep transaction construction out of the React application.

13. Transaction State

Every order needs explicit lifecycle state:

CREATED
   ↓
PREVIEWED
   ↓
RISK_APPROVED
   ↓
SUBMITTED
   ↓
PENDING
   ├── CONFIRMED
   ├── REVERTED
   └── UNKNOWN
Enter fullscreen mode Exit fullscreen mode

The frontend should subscribe to that state.

For example:

BUY ABC

Status:
PENDING

Transaction:
0x1234...
Enter fullscreen mode Exit fullscreen mode

Then later:

CONFIRMED
Enter fullscreen mode Exit fullscreen mode

or:

REVERTED
Enter fullscreen mode Exit fullscreen mode

14. Don't Treat RPC Timeout as Failure

This is particularly important.

Suppose:

Transaction submitted
       ↓
RPC timeout
Enter fullscreen mode Exit fullscreen mode

The transaction may already be onchain.

Therefore:

Timeout
   ↓
Reconcile
   ↓
Check chain
   ↓
Determine state
Enter fullscreen mode Exit fullscreen mode

Never automatically submit the same order again without checking.

15. Wallet Page

Create:

/wallets
Enter fullscreen mode Exit fullscreen mode

Show:

Address
Native Balance
Token Count
Positions
Exposure
Enter fullscreen mode Exit fullscreen mode

For server-managed wallets:

Private keys
Enter fullscreen mode Exit fullscreen mode

must never be shown.

The frontend only receives information necessary for the product.

16. Portfolio Page

Create:

/portfolio
Enter fullscreen mode Exit fullscreen mode

Display:

Total Value
Available Balance
Open Positions
Realized P/L
Unrealized P/L
Exposure
Enter fullscreen mode Exit fullscreen mode

Positions:

Token
Quantity
Entry
Current
Value
P/L
Exposure
Enter fullscreen mode Exit fullscreen mode

Use actual chain-derived balances.

17. Position Manager

The backend should maintain position state:

interface Position {
  tokenAddress: string;

  walletAddress: string;

  quantity: bigint;

  entryCost: bigint;

  currentValue?: bigint;
  pnl?: bigint;

  status:
    | "OPEN"
    | "CLOSING"
    | "CLOSED"
    | "UNKNOWN";
}
Enter fullscreen mode Exit fullscreen mode

But local state is not the final truth.

Reconcile against the chain.

18. Reconciliation

Use:

Local State
    ↕
Reconciliation Service
    ↕
Blockchain
Enter fullscreen mode Exit fullscreen mode

Verify:

transaction receipts
native balances
token balances
positions
order state
Enter fullscreen mode Exit fullscreen mode

Run reconciliation:

after execution
after restart
after timeout
after reconnect
periodically
Enter fullscreen mode Exit fullscreen mode

This is one of the most important parts of the trading terminal.

19. Real-Time Updates

Use WebSocket or SSE for:

new launches
new trades
market changes
order status
positions
portfolio
system status
Enter fullscreen mode Exit fullscreen mode

Architecture:

Robinhood Chain
      ↓
Indexer
      ↓
Event Bus
      ↓
WebSocket
      ↓
Trading Terminal
Enter fullscreen mode Exit fullscreen mode

The frontend should update without refreshing the page.

20. Launch Feed

The terminal should include a live launch section:

RECENT PONS LAUNCHES

ABC
2 sec ago
v2
Curve

XYZ
14 sec ago
v1
Pool
Enter fullscreen mode Exit fullscreen mode

Clicking a launch opens the token page.

The launch feed should consume the existing monitoring infrastructure.

21. Watchlist

Allow users to save tokens:

⭐ ABC
⭐ XYZ
⭐ TOKEN123
Enter fullscreen mode Exit fullscreen mode

Endpoints:

GET    /api/watchlist
POST   /api/watchlist
DELETE /api/watchlist/:token
Enter fullscreen mode Exit fullscreen mode

Watchlist events can later feed alerts.

22. Alerts

Support:

new launch
large trade
price threshold
graduation
order confirmed
order failed
position changed
Enter fullscreen mode Exit fullscreen mode

Architecture:

Event
  ↓
Alert Rules
  ↓
Notification Service
  ↓
WebSocket / Telegram / Discord
Enter fullscreen mode Exit fullscreen mode

Keep notifications separate from the indexer.

23. Sniper Integration

The terminal can expose:

MANUAL
SNIPER
COPY
Enter fullscreen mode Exit fullscreen mode

All three use the same execution stack:

Strategy
   ↓
Risk
   ↓
Quote
   ↓
Execution
   ↓
Transaction
Enter fullscreen mode Exit fullscreen mode

This is much cleaner than building a different executor for every strategy.

24. Copy Trading Integration

A user could configure:

Source Wallet
Copy Ratio
Maximum Position
Maximum Exposure
Maximum Slippage
Enter fullscreen mode Exit fullscreen mode

Then:

Source Trade
      ↓
Copy Strategy
      ↓
Risk
      ↓
Execution
Enter fullscreen mode Exit fullscreen mode

The terminal becomes the control panel for the strategy.

25. Bundler Integration

Launch automation should remain a separate tool.

A useful navigation structure is:

Trading
Sniper
Copy Trading
Launch Automation
Analytics
Enter fullscreen mode Exit fullscreen mode

The standard trading path should not contain multi-wallet launch logic.

26. Database

Suggested tables:

users
wallets
tokens
launches
markets
trades
orders
transactions
positions
watchlists
alerts
checkpoints
Enter fullscreen mode Exit fullscreen mode

Useful indexes:

token_address
wallet_address
transaction_hash
block_number
launch_block
timestamp
Enter fullscreen mode Exit fullscreen mode

Use safe integer storage for blockchain amounts.

Never use JavaScript floating point for token quantities.

27. Backend API

Suggested endpoints:

GET  /api/launches
GET  /api/launches/:token

GET  /api/markets
GET  /api/markets/:token
GET  /api/markets/:token/trades

GET  /api/portfolio
GET  /api/positions

POST /api/orders/preview
POST /api/orders/submit
GET  /api/orders
GET  /api/orders/:id

GET  /api/transactions/:hash

GET  /api/watchlist
POST /api/watchlist
DELETE /api/watchlist/:token

GET  /api/alerts
POST /api/alerts
Enter fullscreen mode Exit fullscreen mode

Use consistent JSON responses.

28. System Status

The terminal header should show:

Robinhood Chain ●
RPC ●
Indexer ●
Database ●
Execution ●
WebSocket ●
Enter fullscreen mode Exit fullscreen mode

Only report ONLINE when the backend verifies that component.

29. Paper Trading

Add:

PAPER_TRADING=true
Enter fullscreen mode Exit fullscreen mode

Paper trading should still calculate:

quotes
risk
position sizing
portfolio changes
Enter fullscreen mode Exit fullscreen mode

but must never broadcast real transactions.

Show a visible:

PAPER TRADING
Enter fullscreen mode Exit fullscreen mode

indicator.

30. Emergency Trading Stop

Implement a global trading control.

When stopped:

New orders → rejected
Enter fullscreen mode Exit fullscreen mode

but:

Market monitoring → continues
Reconciliation → continues
Portfolio → continues
Enter fullscreen mode Exit fullscreen mode

This provides a safe operational kill switch.

31. Security

The terminal should follow:

Frontend
    ↓
   API
    ↓
  Risk
    ↓
Execution
    ↓
 Signer
    ↓
Blockchain
Enter fullscreen mode Exit fullscreen mode

Never:

Frontend
    ↓
Private Key
Enter fullscreen mode Exit fullscreen mode

Server-managed credentials must remain isolated.

32. Testing

Test:

launch indexing
market state
token search
chart data
order preview
risk checks
quote expiration
duplicate order prevention
transaction lifecycle
reconciliation
portfolio updates
watchlist
alerts
Enter fullscreen mode Exit fullscreen mode

End-to-end:

Launch
 ↓
Open Token
 ↓
Preview Order
 ↓
Risk Check
 ↓
Confirm
 ↓
Transaction
 ↓
Position
 ↓
Portfolio
Enter fullscreen mode Exit fullscreen mode

33. Project Evolution

The first version should focus on:

Launches
Markets
Token Detail
Charts
Order Preview
Paper Trading
Enter fullscreen mode Exit fullscreen mode

Then add:

Live Execution
Transactions
Positions
Portfolio
Reconciliation
Enter fullscreen mode Exit fullscreen mode

Then:

Sniper
Copy Trading
Alerts
Analytics
Enter fullscreen mode Exit fullscreen mode

That produces a useful product at every stage.

Final Architecture

The complete system is:

                       │ Positions          │
                       │ Portfolio          │
                       └────────────────────┘
Enter fullscreen mode Exit fullscreen mode

This is the important distinction:

A dashboard
Enter fullscreen mode Exit fullscreen mode

shows information.

A:

Trading Terminal
Enter fullscreen mode Exit fullscreen mode

connects:

Data
+

From Terminal to Trading Platform

Once the terminal is working, the product portfolio becomes:

Pons Launch Monitor
        ↓
Pons Trading Terminal
        ↓
┌─────────────────────────┐
│ Manual Trading          │
│ Pons Sniper             │
│ Pons Copy Trading       │
│ Pons Bundler            │
│ Pons Analytics          │
└─────────────────────────┘

That shared infrastructure can then extend into:

Stock Token Arbitrage
Stock Token Trading
Stock Token Rebalancing
Stock Token Trading Terminal

The underlying engineering remains the same:

Need a Pons Trading Terminal Built?

I build custom Robinhood Chain trading infrastructure covering:

Pons Trading Terminals
Pons Launch Monitors
Pons Sniper Bots
Pons Copy Trading
Pons Bundlers
Risk Engines
Execution Systems
Portfolio Tracking
Trading APIs
Reconciliation
Enter fullscreen mode Exit fullscreen mode

The system can be designed around the client's Pons protocol version, data requirements, execution workflow, wallet architecture, trading strategies, and risk controls.

"Don't treat RPC timeout as failure" is the sentence I'd underline in the whole document. We run a system that drives remote sessions through a flaky boundary, and every time we were tempted to collapse an unknown-outcome state into "failed", we eventually got bitten by the action having actually landed. Making UNKNOWN a first-class state in the order lifecycle — with its own reconcile path and, crucially, its own UI representation — is the correct call, and "Timeout → Reconcile → Check chain → Determine state" is the loop most dashboards skip.

Same reasoning behind keeping construction out of the React layer, by the way: the moment transaction building lives in the UI, every retry question becomes a component-state question. One thing I'd ask: how are you bounding the reconcile loop? If the chain node stays unreachable, UNKNOWN has to decay into something eventually, and that policy is where these architectures usually get honest.
