# Introduction

> TxShield — Pre-flight security intelligence for Web3 transactions. Simulate, detect, and protect before funds move.

# TxShield API

Every second, thousands of wallets lose funds to honeypots, drainers, and malicious contracts.
TxShield is the security layer that catches them **before the transaction is signed.**

We give DEX aggregators, wallets, and developers a single API to run real-time pre-flight
checks on any token or contract — simulating exactly what will happen to a user's wallet
before they approve anything.

## What TxShield Does

<CardGroup cols={2}>
  <Card title="Transaction Simulation" icon="flask" href="/evm-simulation-copied-1">
    Simulate a swap or interaction against live chain state. Get exact token deltas,
    ETH changes, tax rates, reentrancy flags, and failure reasons — before the user signs.
  </Card>

  <Card title="Honeypot Detection" icon="spider-web" href="/evm-honeypot-copied-1">
    Time-travel analysis across multiple future states (Immediate, 24h, 7 Days).
    Catches buy/sell tax traps, blacklist mechanisms, mint abuse, and trading controls.
  </Card>

  <Card title="Bytecode Analysis" icon="code" href="/evm-simulation-copied-1">
    Deep static analysis of contract bytecode. Flags kill switches, proxy patterns,
    hidden logic, and dynamic deployment — the stuff token screeners miss.

## Who Uses TxShield

**DEX Aggregators & Screeners** — Add a TxShield risk badge on every token page.
Alert users before they trade a honeypot. Platforms like GMGN, DexScreener integrations,
and token screeners use security layers exactly like this.

**Wallet Developers** — Run a pre-flight check before presenting a transaction to sign.
Show users their exact balance delta and any detected risks inline in the signing prompt.

**Trading Bots & Snipers** — Filter out honeypots and high-tax tokens automatically
before entry. Protect your bot's capital at the RPC level.

**Security Researchers & Developers** — Programmatic access to simulation, bytecode
analysis, and honeypot detection for any contract on supported chains.

## How It Works

```
Your App  →  POST /api/simulate  →  TxShield runs simulation + bytecode + history checks
                                  →  Returns unified risk report in one response
                                  →  You show the result to your user before they sign
```

One request. One response. Full picture.

## API Access

TxShield uses API key authentication. All analysis endpoints require a valid key
passed in the `Authorization` header.
