Blockchain technology has revolutionized digital trust and decentralized interaction, but with innovation comes new security challenges. As transaction volumes grow and smart contract complexity increases, the risk of malicious activity escalates. To address this, GoPlus Security introduces a transformative solution: the On-Chain Firewall—a native, real-time defense mechanism designed to safeguard users at the protocol level.
Unlike traditional security tools that rely on pre-transaction warnings or manual risk assessments, the On-Chain Firewall operates automatically and seamlessly within the blockchain infrastructure. It actively monitors, analyzes, and blocks high-risk transactions in real time, ensuring protection without disrupting user experience.
This next-generation security layer marks a shift from reactive to proactive defense, embedding risk control directly into the transaction lifecycle.

Core Features of the On-Chain Firewall
Real-Time Transaction Monitoring
The firewall continuously scans all incoming and outgoing transactions across supported blockchains. Using advanced on-chain analytics and threat intelligence, it identifies suspicious patterns—such as known malicious addresses, phishing contracts, or rug-pull indicators—as they occur.
This real-time monitoring ensures that threats are detected at the earliest possible moment, minimizing exposure windows and preventing irreversible losses.
Automatic Risk Blocking
When a transaction is flagged as high-risk, the On-Chain Firewall intervenes instantly. Instead of merely issuing an alert—which users may ignore—the system proactively halts the transaction before execution.
This automatic blocking capability is crucial in environments where split-second decisions determine whether funds are saved or lost. Whether it's a wallet drain attempt or interaction with a fraudulent dApp, the firewall acts as an invisible shield.
Seamless Integration, Zero Friction
One of the biggest challenges in blockchain security is user adoption. Many protective tools require additional steps, configuration, or technical knowledge. The On-Chain Firewall eliminates this barrier by operating invisibly in the background.
Users benefit from enhanced security without changing their behavior or installing extra software. The protection is built into the infrastructure itself—making security both powerful and effortless.
How the On-Chain Firewall Works: A Three-Stage Implementation
To deliver native-level security across diverse blockchain ecosystems, GoPlus employs a strategic, multi-layered integration approach. This ensures comprehensive coverage while maintaining compatibility with existing protocols and developer workflows.
1. GoPlus Intelligence Integration
At the foundation of the On-Chain Firewall is GoPlus Intelligence—a robust security engine that provides real-time risk analysis for transactions and smart contracts.
Key components include:
- Customized Threat Intelligence: Tailored data models for each blockchain to detect chain-specific risks.
- Developer-Friendly APIs & SDKs: Allow wallets, exchanges, and dApps to integrate real-time security checks with minimal effort.
- Smart Contract Risk Scoring: Instant evaluation of contract safety, including ownership centralization, mint function exposure, and blacklist status.
- Behavioral Analysis Engine: Detects anomalies in transaction patterns that may indicate fraud or exploit attempts.
By embedding GoPlus Intelligence into applications, developers can offer users proactive protection without sacrificing speed or functionality.

2. Secure RPC Service Provision
Remote Procedure Call (RPC) nodes are the gateway between users and the blockchain. If compromised or unsecured, they can be exploited to manipulate transaction data or inject malicious payloads.
GoPlus addresses this vulnerability by deploying Secure RPC Services—trusted, hardened endpoints that include built-in security filtering.
Benefits include:
- Transaction Pre-Screening: Every request routed through GoPlus Secure RPC is analyzed before reaching the network.
- Malicious Payload Detection: Filters out known attack vectors such as fake approvals or malicious calldata.
- High Availability & Low Latency: Ensures performance isn’t sacrificed for security.
- Trustworthy Infrastructure: Reduces reliance on third-party nodes that may lack transparency or audit trails.
This layer acts as a first line of defense, ensuring that only clean, verified transactions enter the blockchain environment.
3. Native Blockchain Integration
The most advanced stage involves direct integration of a User Security Module (USM) into the blockchain’s core architecture.
This means:
- Security checks become part of the consensus or validation process.
- Risk assessment occurs at the protocol level—not just at the application or node level.
- Transactions from blacklisted addresses or interacting with dangerous contracts are rejected natively.
- The blockchain gains built-in immunity to common attack types like flash loan exploits or honeypot scams.
Such deep integration transforms the blockchain from a neutral ledger into an intelligent, self-protecting ecosystem—where safety is not an add-on but a fundamental feature.
Frequently Asked Questions (FAQ)
Q: How does the On-Chain Firewall differ from traditional wallet alerts?
A: Traditional systems only warn users about potential risks, relying on them to make safe choices. The On-Chain Firewall goes further by automatically blocking dangerous transactions—eliminating human error and providing true protection.
Q: Does the firewall slow down transactions?
A: No. The system is optimized for speed and operates at the infrastructure level. Security checks happen in parallel with transaction processing, resulting in no noticeable latency for end users.
Q: Can developers customize the firewall rules for their dApp?
A: Yes. Through GoPlus APIs and SDKs, developers can define custom risk thresholds, whitelist trusted contracts, and receive real-time alerts—giving them full control over their app’s security posture.
Q: Which blockchains currently support On-Chain Firewall?
A: The solution is being rolled out across major EVM-compatible chains, with plans to expand to non-EVM networks. Support includes Ethereum, BNB Chain, Arbitrum, and others.
Q: Is user privacy preserved with real-time monitoring?
A: Absolutely. All analysis is performed on-chain using public data. No personal information or private keys are collected, stored, or transmitted.
