Blocknative primary-source snapshot

Fetched: 2026-04-26 UTC

1) Official website

Source: https://www.blocknative.com/

Selected excerpts from the official site:

Web3’s Most Trusted Gas Solution

Gas Prediction APIs. Mempool Data. L2 Decoding. Wallet Onboarding.

Additional signals from the site:

  • The homepage markets Blocknative around gas and transaction-intelligence primitives rather than generic node access
  • The audience is mixed: L1s/L2s, builders, wallets, and consumer-facing fee users all appear in the same first-party surface
  • The product framing suggests Blocknative sits at the intersection of wallet UX, protocol operations, and fee-market data

2) Docs overview

Source: https://docs.blocknative.com/

Selected excerpts from the docs:

Blocknative delivers over 600 gas estimates per second.

We are bringing gas markets onchain with Gas Network.

Additional signals from the docs:

  • The docs make gas estimation and prediction the core product, not a side feature
  • The overview links together API-based gas estimation, base-fee prediction, browser tooling, and Gas Network as one coherent stack
  • The docs also expose an ?ask= query pattern, which is a useful sign that the documentation is meant to function as an active product interface, not just brochureware

3) Gas Price API docs

Source: https://docs.blocknative.com/gas-prediction/gas-platform

Selected excerpts from the docs:

The Gas Price API gives you the gas price needed to have a certain probability to qualify for inclusion in the next block (for Ethereum or Bitcoin) or the next ∼10 seconds, depending on the chain.

43 chains currently supported.

Additional signals from the docs:

  • Blocknative emphasizes probability-based inclusion estimates instead of a single fee quote, which is a meaningful product distinction
  • The chain table is a strong first-party source for current network coverage and shows the product extends well beyond Ethereum mainnet
  • Support for Bitcoin alongside many EVM/L2 networks suggests the company is positioning around transaction-cost intelligence more broadly than “Ethereum gas tracker” branding implies

4) Gas Network website

Source: https://gas.network/

Selected excerpts from the official site:

Support for 40+ Chains

Gas Network delivers real-time fee pricing data.

Gas Agents … generate continuous gas fee predictions.

Gas Oracles … publish aggregated gas data to each supported chain

Additional signals from the site:

  • Gas Network makes Blocknative’s newer protocol/network ambitions explicit by describing a dedicated chain, agents, and onchain oracles
  • The site frames fee data as infrastructure that protocols and contracts can consume, not just something humans read in a dashboard
  • This material is the clearest signal that Blocknative should be cataloged as fee-market infrastructure rather than only a gas-estimator brand

5) Extension page

Source: https://www.blocknative.com/gas-extension

Selected signals from the extension surface:

  • The public extension page doubles as a discovery surface for Blocknative’s recent gas-market writing and Gas Network rollout materials
  • The extension reinforces that Blocknative still serves end users directly even as its deeper product identity moves toward developer/protocol infrastructure
  • The coexistence of extension UX and protocol/oracle materials is useful context for understanding the full operating surface

6) Official GitHub organization and repos

Source: https://github.com/blocknative Source: https://raw.githubusercontent.com/blocknative/gas-agent/main/README.md Source: https://raw.githubusercontent.com/blocknative/gas-network-visual-demo/main/README.md

Selected excerpts from the repo materials:

Create gas predictions and publish them for evaluation and submission to the Gas Network

A Rust-based agent system that generates and submits gas price predictions for EVM networks to the Gas Network for evaluation.

This is a demo for testing the Gas Network.

Additional signals from the repos:

  • The public org shows Blocknative shipping open-source tooling that is directly tied to the Gas Network workflow, not just marketing pages
  • The gas-agent README documents signed submissions, whitelisting, key generation, and operator configuration, all of which make the network/control-plane posture more concrete
  • The visual demo repo shows cross-chain oracle reads/writes as a first-party supported workflow, which is a strong signal that the onchain oracle layer is real product surface area

Notes

  • This pass did not locate a classic whitepaper or litepaper from official Blocknative sources.
  • Blocknative appears best categorized as gas-fee infrastructure / fee-market data / onchain gas oracle network.
  • The strongest primary materials were the website, docs overview, Gas Price API docs, Gas Network site, extension surface, and public GitHub repos.
