Blowfish

Blowfish is a proactive security platform focused on protecting web3 wallet users from scams, fraud, and malicious dapps. The service scans transactions and messages, simulates signing behavior, and provides real-time risk signals aggregated from multiple intelligence sources across 10+ chains. Blowfish is positioned as a wallet-first defense layer offering Transaction Security, Message Simulation, and Dapp Security to alert users before they engage with harmful operations. Its metrics emphasize scale and reliability — millions of scams prevented, billions of transactions scanned, and over ten billion dollars in assets protected. With simple API integration, developer documentation, and SDKs, Blowfish aims to be the standard trust-and-safety engine embedded by leading wallets and dapps to improve security UX and reduce user losses.

Introduction

Overview

Blowfish is a proactive defense platform built specifically for web3 wallets and wallet-integrated experiences. It’s designed to identify and stop fraud before users sign transactions or connect to risky decentralized applications. By combining internal intelligence with aggregated risk signals from multiple external sources, Blowfish provides a consolidated safety layer that wallets can integrate quickly to provide clearer, safer signing and connection experiences.

Core Capabilities

  1. Transaction Security: Analyze and simulate on-chain transactions to detect suspicious operations, unexpected approvals, or potential fund transfers before users confirm signatures.

  2. Dapp Security: Scan and evaluate decentralized applications and domains to warn users when a connected dapp exhibits phishing, impersonation, or other malicious behaviors.

  3. Message Simulation & Verification: Simulate message signing flows and interpret intent to detect deceptive signing requests or data exfiltration attempts.

  4. Aggregated Risk Signals: Combine intelligence from 10+ sources alongside its own internal lists and heuristics to deliver consolidated risk assessments for addresses, domains, and contract interactions.

  5. Developer APIs & Integration Tools: Offer straightforward APIs, documentation, and integration guides so wallets and dapps can embed protections with minimal friction.

How It Works

  • Signal Aggregation: Blowfish ingests data from multiple feeds — blacklist databases, behavioral signals, heuristic detectors, and partner intelligence — to build a real-time view of risk across chains.

  • Simulation & Analysis: Before a user signs a transaction or message, Blowfish simulates the effect of that action to surface hidden transfers, approvals, or unexpected calls.

  • Real-time Alerts: When a high-risk pattern is identified, Blowfish returns clear, actionable warnings that can be surfaced in the wallet UI to help users make informed decisions.

  • Metrics & Continuous Learning: The platform reports usage metrics and outcomes; examples shown on the site include millions of scams prevented, over a billion transactions scanned, and more than $10 billion in assets protected — evidence of scale and iterative improvement.

Integration & Developer Experience

  1. API-first Design: Blowfish exposes REST/HTTP endpoints and SDKs for common stacks so developers can call risk checks synchronously during connection and signing flows.

  2. Documentation & Examples: Comprehensive docs and quick-start guides help teams implement Dapp Security and Transaction Security with example payloads, response schemas, and recommended UI patterns.

  3. Quick Onboarding: A free tier and portal sign-up let teams test protections early; the integration is positioned as quick and simple to reduce friction for product teams.

  4. Cross-chain Support: Multi-chain coverage ensures the same trust-and-safety rules apply across Ethereum, Solana, and other supported networks.

Why Choose Blowfish

  • Wallet-centered UX: Blowfish focuses on improving the signing and connection experience so end users receive contextual, clear warnings at the moment of risk.

  • Consolidated Signals: Instead of wiring multiple threat feeds, integrators get a unified risk view that reduces false positives and prioritizes actionable alerts.

  • Proven Scale: Public metrics and testimonials from leading wallets and integrations signal a product already trusted at scale.

  • Flexible Integration: The product supports synchronous checks, batch processing, and webhooks, enabling both real-time protection and offline analysis.

Recommended Use Cases
  • Pre-sign transaction simulation and risk display in wallet signing UX
  • Real-time dapp domain and contract reputation checks during connection flows
  • Monitoring and alerting for enterprise custodial or custodial-like wallet operations

LTC-20Developer ToolsBlock explorer

The page at /ltc-20 on litecoin.com returns a 404 “Page not found,” indicating the specific resource has been removed or relocated. Based on the URL and the host domain, the missing page was likely intended to describe “LTC-20,” a token-related concept or standard connected to the Litecoin ecosystem. LTC-20 can be understood generally as a fungible token specification or programmatic token layer intended to enable token issuance, transfer, and interaction on Litecoin-compatible infrastructure, helping projects launch tokens that integrate with wallets, explorers, and marketplaces. Although the original page content is unavailable, LTC-20 is commonly referenced as a way to expand Litecoin’s on-chain use cases, enabling developers and users to create tokens, manage supply, and improve compatibility across tooling and services.

LTC-20Developer ToolsWeb3

LTC-20 is presented as a token standard associated with the Litecoin project, intended to provide a fungible token interface analogous to ERC-20 on Ethereum. Although the specific GitHub repository at https://github.com/litecoin-project/ltc-20 currently returns a “Page not found” (404) on GitHub, the name implies a specification for minting, transferring, and managing tokens within the Litecoin ecosystem or compatible layers. The standard likely targets interoperability, simple transfer and allowance mechanics, and integration with wallets and explorers while remaining lightweight and aligned with Litecoin’s design principles. Because the original repository is unavailable, developers and integrators should seek official Litecoin Project channels, archived copies, or other authoritative sources before implementing or relying on the standard in production.

Block explorerData on the chainDeveloper Tools

Mempool (mempool.space) is a real-time blockchain explorer and mempool visualizer designed to provide detailed, up-to-the-second information about transactions, fees, and recent blocks for UTXO-based networks such as Bitcoin and Litecoin. The site aggregates mempool state, fee-rate estimates, transaction replacements (RBF), recent block listings, mining pool attribution, and various network metrics like difficulty and average block time, presenting them in a clear, interactive interface. Users can inspect individual transactions, view recommended fee rates for different confirmation targets, and monitor unconfirmed transaction counts and memory usage. For both casual users and advanced operators, Mempool offers a blend of high-level summaries and granular data that helps with fee selection, transaction tracking, and general chain monitoring.
