As real-world assets move onchain and AI agents begin automating financial decisions, one challenge developers face frequently is that most onchain actions still execute without awareness of network conditions, leading to costly, inefficient transactions.

Today, we’re introducing the Etherscan Data Oracle, an open-source integration built on Newton Protocol that connects Etherscan’s real-time gas and network data with programmable transaction guardrails.

Bringing Etherscan Data into Newton Protocol

The Etherscan Data Oracle connects Etherscan’s Gas Tracker API to Newton Protocol’s decentralized policy engine, allowing developers to set pre-execution conditions that optimize cost and prevent unnecessary transaction failures.

With a few lines of configuration, developers can create policies that:

  • Execute a transaction only when gas prices fall below a defined threshold.
  • Delay or block transactions during periods of high congestion.
  • Trigger a smart agent to rebroadcast or re-price transactions as network demand shifts.

Each check runs through Newton Protocol’s decentralized operator network, evaluating Etherscan data off the execution chain, verifying it for integrity, and anchoring an attestation onchain for auditability.

Example Use Cases

The Etherscan Data Oracle includes gas fee data, enabling developers to enforce cost and efficiency rules such as executing transactions only when gas prices fall below a set threshold or delaying actions during network congestion.

But this is just the starting point. Developers can easily extend or customize their own policies using other Etherscan APIs or any external data source to power richer, data-informed guardrails. Examples include:

  • Contract and token checks: Only interact with approved smart contracts and wallets with a minimum balance.
  • Transaction history and risk: Block transactions with wallet addresses that have suspicious transaction patterns.
  • Counterparty and address risk: Use Etherscan’s address labeling (e.g., exchanges, bridges, mixers) to automatically allow or block interactions with specific counterparties based on their risk profile.
  • Dynamic logic: Combine gas data with fiat price feeds, oracles, or offchain APIs to control execution timing, fees or asset exposure.

Why Newton Protocol Is Different

Most automation systems execute transactions blindly or embed static logic in smart contracts, making them rigid and opaque. Newton Protocol separates policy enforcement from execution, creating a programmable layer that is:

  • Modular: Define once, apply across contracts, chains, and agents.
  • Composable: Combine onchain and offchain data for adaptive transaction logic.
  • Updatable: Adjust thresholds or rules without redeploying contracts.
  • Verifiable: Every policy evaluation generates a cryptographic attestation visible on Newton Explorer.
  • Credibly Neutral: Enforcement runs through a decentralized operator network secured by EigenLayer restaking.

Newton Protocol turns automation and compliance controls into code, giving lean teams the efficiency and assurance typically reserved for institutions with full risk and compliance operations.

Get Started

Developers can now use the Etherscan Data Oracle to bring real-time network awareness and transaction optimization into their DeFi, automation, or AI agent workflows.

With Newton Protocol, developers can compose policies with live data to meet any business, efficiency, or regulatory requirement.
