Practical overview

When it fits

Use it when developing or operating Witnet oracle integrations on an EVM-compatible network, especially when you need to inspect available feeds, consume oracle data, or connect a local gateway to a supported chain.

Who it is for

  • Solidity developers building contracts that consume Witnet price feeds or randomness.
  • JavaScript developers using ethers providers and Witnet wrappers.
  • Operators inspecting framework contracts or starting a local signing gateway for a supported chain.

Documented uses

  • Discover subsidized feeds and inspect their identifiers, freshness, and providers.
  • Read oracle prices through Witnet-native or documented compatibility interfaces.
  • Browse randomness requests and inspect oracle queries, reports, and Radon assets.
  • Connect a local signing gateway to a listed chain and inspect its framework contracts.
Before you choose

Requirements & limits

The repository is public and licensed under MIT. The documented operator setup uses pnpm; Solidity package and JavaScript wrapper examples use npm.

  • Check npx witeth networks to identify chains listed as supported.
  • Native feed reads include freshness-aware methods; the documented ERC-2362-style path instead reports health through status codes.
  • JavaScript wrapper examples require an ethers JSON-RPC provider.
  • Deployment and upgrade execution is left to the operator’s internal automation and approved processes.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Set up an operator gateway and inspect contracts

Install the project dependencies, select a listed chain, start its local signing gateway, and inspect framework contracts.

Before you start

  • A local environment with pnpm and access to the repository
  • A target ecosystem:chain identifier shown by the network listing

Steps

  1. Run pnpm install.

  2. Run the command below to list supported chains.

    Documented command
    npx witeth networks

  3. Run the command below for the target network.

    Documented command
    npx witeth gateway

  4. In another terminal, run the command below.

    Documented command
    npx witeth framework --verbose

Expected outcome

A local signing gateway is started for the selected chain, and the framework contracts can be inspected with verbose output.

Guide limitations

  • The guide documents gateway startup and contract inspection, not deployment or upgrade execution.
  • Deployments and upgrades use the operator’s internal automation or playbook.

Install the Solidity package and browse oracle resources

Install the Solidity package and use the documented CLI commands to inspect feeds, randomness requests, queries, reports, and Radon assets.

Before you start

  • A local environment with npm and the project CLI available

Steps

  1. Run the command below.

    Documented command
    npm install @witnet/solidity

  2. Run the command below and the command below.

    Documented command
    npx witeth priceFeeds
    Documented command
    npx witeth randomness

  3. Inspect queries with the command below and parsed reports with the command below.

    Documented command
    npx witeth queries --limit 20
    Documented command
    npx witeth reports --limit 20 --parse

  4. Decode assets with the command below, or dry-run a named asset with the command below.

    Documented command
    npx witeth assets --all --decode
    Documented command
    npx witeth assets --dry-run

Expected outcome

The documented commands provide listings and inspection output for oracle feeds, randomness requests, queries, reports, and Radon assets.

Guide limitations

  • These steps document package installation and CLI inspection; they do not deploy a contract or execute an application integration.
