In the realm of cryptocurrency and blockchain technology, security and transparency are paramount. Safe, a leading decentralised digital wallet known for its robust features and user-friendly interface, has gained prominence among crypto enthusiasts and institutions. If you're excited to delve into the dynamic world of Safe multisig and are looking to establish a Subquery indexer for it, this guide is here to assist you.

This guide acts as your entry point to the efficient indexing of signature data in the Safe protocol ecosystem, empowering users to navigate the multisig transactions. The Safe protocol extends its operations to various blockchain networks, and for developers aspiring to create the next decentralised application that seamlessly spans multiple chains, the ability to concurrently index multiple blockchains is an indispensable requirement for their endeavours. SubQuery has proactively stepped in to address this need, introducing a groundbreaking solution known as Multi-Chain Indexing.


The Snapshot sample project gathers data related to Delegations. Key resources:


Once you initiate the project, you'll have the choice to launch the queries. In this context, the only entity under consideration is "Sig," and it serves as the exclusive channel through which we can gain valuable insights. Let's explore the following illustration:

The query above retrieves individual signatures executed within the context of a Safe smart multisig contract. An instance of this contract is generated for each user's multisig wallet. Given this case, we had employed the dynamic datasource in the configuration. This means that we can now access them using the subsequent query:

Considering that this project spans multiple blockchains, we have the capability to query not only the datasources but also the project's metadata. This can be accomplished using the following query:

Furthermore, when you combine multi-chain capabilities with aggregations, it opens up significant possibilities for cross-chain analysis without a need to exit the GraphQL interface to gain insights into specific subject matters.
