Blocknative

Blocknative is a Web3 infrastructure company focused on making gas markets transparent, programmable, and more efficient across blockchains. They provide real-time mempool data, gas prediction APIs, L2 decoding, and developer tooling that help wallets, exchanges, and builders estimate fees, monitor transactions, and improve onboarding flows. Blocknative is the core team behind the Gas Network, an effort to decentralize critical transaction and gas market data and to enable on-chain games and multichain gas market experimentation. Their research and media presence also highlight topics like MEV, transaction distribution, and the operational challenges of both L1s and L2s, positioning Blocknative as a practical partner for teams optimizing transaction reliability and cost.

Introduction

Overview

Blocknative is a purpose-built infrastructure provider for transaction and gas market data in the Web3 ecosystem. Founded to address the opacity and inefficiencies of blockchain transaction flows, Blocknative powers real-time visibility into the mempool, supplies predictive gas APIs, and builds tooling aimed at both developers and network operators. Its initiatives — notably the Gas Network — seek to decentralize access to critical transaction data and to improve fee predictability and transaction success rates across Layer 1 and Layer 2 networks.

Core Capabilities

  1. Real-time Mempool Data: Blocknative offers continuous, low-latency access to mempool events, enabling applications to observe pending transactions, track replacements, and detect front-running or MEV patterns before transactions are mined.

  2. Gas Prediction APIs: Their APIs provide dynamic fee estimates and probability-based predictions for transaction inclusion, which help wallets and dApps set competitive yet cost-efficient gas parameters.

  3. L2 Decoding & Cross-chain Support: Blocknative supports decoding and interpreting Layer 2 transaction payloads and extends compatibility across multiple chains, helping teams maintain consistent UX and monitoring across ecosystems.

  4. Wallet Integration & Onboarding Tools: The platform supplies integrations and tooling for wallet developers to improve transaction reliability, display clearer fee guidance to users, and reduce failed transactions caused by incorrect gas settings.

  5. Research & Monitoring Tools: Blocknative publishes analysis on MEV, gas market behavior, and network events, and offers operational services for L1/L2 teams to optimize performance, troubleshooting, and fee mechanisms.

How It Works

Blocknative aggregates data from network nodes and relays to construct a real-time view of pending transactions and fee markets. Their systems analyze mempool dynamics and apply statistical models to produce actionable gas estimates and inclusion probabilities. Developers can access these outputs through REST and WebSocket APIs, enabling integration into wallet UIs, monitoring dashboards, and backend transaction managers. The Gas Network initiative expands this model to a decentralized marketplace for gas-related data, allowing experimentation with multichain gas mechanisms and on-chain gaming experiences focused on market behavior.

Use Cases and Beneficiaries

  • Wallet providers use Blocknative to improve UX by showing accurate fee ranges, avoiding failed transactions, and enabling user-friendly retry flows.

  • Exchanges and DeFi protocols leverage mempool feeds and prediction models to reduce slippage, improve order routing, and mitigate MEV risks.

  • Layer 1 and Layer 2 operators adopt Blocknative’s infrastructure to streamline diagnostics, improve block inclusion performance, and optimize network-level fee parameters.

  • Builders and researchers use published Blocknative Research to understand MEV dynamics, post-merge outcomes, and the economics of transaction distribution.

Why Choose Blocknative

Blocknative combines practical developer tooling with research-backed insights. Its core strengths are low-latency mempool visibility, robust predictive models for gas, and broad compatibility across L1s and L2s. This makes it a strong choice when your team needs reliable fee estimation, transaction monitoring, and actionable alerts to reduce failed transactions and unexpected costs. The company’s media and research presence — including partnerships and citations in industry outlets — further demonstrates credibility and domain expertise.

Getting Started & Integration

Integration typically involves obtaining API credentials, connecting via WebSocket for real-time mempool events, and wiring gas prediction endpoints into wallet or backend transaction flows. Blocknative provides documentation, SDKs, and examples to accelerate adoption and to surface best practices for handling network congestion, transaction replacement (nonce management), and user-facing fee guidance.

Conclusion

Blocknative addresses a core pain point in Web3: unpredictable and opaque gas markets. Through a blend of real-time data, prediction services, and ecosystem research, it helps teams improve transaction reliability, reduce user friction, and gain clearer visibility into mempool and fee dynamics. Whether you are building a wallet, operating an L2, or optimizing a DeFi protocol, Blocknative provides practical infrastructure and insights to make transaction flows more transparent and programmable.

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.
