Using a block explorer to interact with Gro Protocol

Published in

Gro DAO

12 min readNov 8, 2023

Gro DAO is winding down. Accordingly, Gro products are no longer under development and automated harvesting of its various strategies has been disabled. This means Gro products are no longer generating yield.

Any assets deposited into products can always be accessed directly on the blockchain (to be withdrawn, for example). For easiest access, it is recommended to use the Gro Protocol frontend, which is hosted as a decentralised IPFS interface on https://app.gro.xyz/ (with the following CID QmeeEj3kpAk4Cd4aY93yKy35vjDyENRm3LFAG5LzVdhfU6 — also accessible through IPFS gateways such as Fleek, IPFS and Cloudflare). However, if for whatever reason, the IPFS interface goes down or is unavailable; direct interaction with the smart contracts is possible via block explorers and the instructions below.

*How to use block explorers to interact with Gro Protocol’s smart contracts*

This article explains how a user can interact directly with the Gro Protocol smart contracts — through a block explorer like Etherscan (for Ethereum) or Avascan (for Avalanche). In theory, however, any block explorer would work to achieve the same result, assuming it is compatible with the network on which the smart contracts operate.

To understand why Gro DAO is winding down and halting its product development, and what this means, please refer to this FAQ article (which is also stored on IPFS with the following CID QmTco3nqbLHigihSiMy5phQNCjDEmj2jwUtLSz8WAGYnWe — accessible through an IPFS gateway such as: Pinata, IPFS, Cloudfare or Fleek).

What is a block explorer?

A block explorer is a handy tool for viewing blockchain data (e.g. blocks, transactions, addresses, and fees) and for interacting with smart contracts. You can think of it as a blockchain search engine, that makes transparent blockchain data, more accessible and digestible.

In this guide, Etherscan (for Ethereum) and Avascan (for Avalanche), will be used as examples. For each of the actions below, you need to make sure to ‘Connect to web3’ or ‘Connect wallet’ respectively.

Make sure to ‘Connect to Web3’ on Etherscan

Make sure to ‘Connect wallet’ on Avascan
