Testnet Guide

Introduction

Integrating with the Venn testnet allows you to safely validate your integration and setup while experiencing the functionality of Venn’s security infrastructure in a controlled environment.

By joining the testnet, you can explore how Venn actively protects your smart contracts from threats, fine-tune your security, and optimize performance — without the concerns of deploying on the mainnet or disrupting your operations.

This guide will walk you through the steps to test Venn’s capabilities, helping you build confidence in your configurations before going live in Mainnet.

We're on Holesky! (additional testnets coming soon)

Tip: Getting a Holesky Faucet. To interact with the Venn testnet, you'll need Holesky testnet tokens. You can easily get them from one of the following Holesky faucets:

Mock Rejection

When testing the integration between Venn and your protocol, you will want to make sure that the integration works as expected both for approved as well as unapproved transactions.

To facilitate this, we've created a dedicated endpoint that will always reject incoming transactions, allowing you to test how your application handles such scenarios. This endpoint can then be used in the DApp SDK.

For the best developer experience, we recommend using environment variables for the vennURL parameter

// Reading vennURL from the VENN_NODE_URL env variable
// allows your to easily switch between the real endpoint
// and the mock-rejection endpoint, without making changes
// to your DApp's code
//
const vennURL = process.env.VENN_NODE_URL;
const vennClient = new VennClient({ vennURL, ... });
