Airdrops

The Graph​

This subgraph tracks events emitted by the @sablier/v2-periphery contracts, specifically the ones in charge of merkle distributions. It deals with airdrops-specific actions like the factory creating an airstream campaign, admin clawbacks, or users claiming stream NFTs as defined in the attached Merkle tree.

Airdrops work in tandem with vesting as Merkle distributions will produce new lockup streams. Be sure to check out that part of the docs too.

Since The Graph has sunset their Hosted Service, we've transitioned our subgraphs to either the Studio or The Decentralized Network. See the supported networks and our endpoints below.

Envio​

This indexers tracks the events emitted by the @sablier/v2-periphery contracts, specifically the ones in charge of merkle distributions. It deals with airdrops-specific actions like the factory creating an airstream campaign, admin clawbacks, or users claiming stream NFTs as defined in the attached Merkle tree.

Chains: Individual vs. Aggregated

While subgraphs are chain-tethered (one subgraph endpoint per chain), Envio indexes all chains within the same deployment. The data from all of chains that Sablier is deployed on can be queried from a single endpoint.

Endpoints​

All-Networks3https://indexer.hyperindex.xyz/[...]/v1/graphql

The endpoint is meant to be plugged into a query client. Use Hasura's online explorer to view the entities and query API.

Sablier SDK: Merkle API​

Sablier's Airdrops rely on pre-configured Merkle trees. This data structure contains the list of recipients as well as their individual claim details. We use the following service to create the Merkle tree, as well as proofs for the recipient's claims.

Footnotes​

  1. The Graph's Studio endpoints are considered for testing purposes and may be rate-limited ↩

  2. Endpoints could include the following types: (1) The Graph's Decentralized Network (paid) or (2) Custom Nodes (e.g. LightLink). Because the "Decentralized Network" subgraph flavors (e.g., Legacy Ethereum) operate on The Graph Network, you will need to substitute the YOUR_API_KEY placeholder in the Query URL with your own API key. If you require assistance with managing your API keys and configuring indexer preferences, this article serves as an excellent guide ↩

  3. All-Networks means most of the networks supported by Sablier, e.g., Mainnet, Optimism, Polygon, Sepolia. The full list can be found here. To add a new chain to our Envio indexer, create a new list of contracts (/addresses) and import that configuration into our bundles (see /bundles). ↩
