This section provides information specific to the Arbitrum blockchain.

Open Toolbox Open Performance Open API Management (RPC & Subgraphs)

Chain.Love on Arbitrum is a set of modules that help you discover providers, monitor them, and (optionally) access RPC/Subgraphs through an API gateway.

Recommended workflows

• Discover providers (start here): open the Toolbox → browse categories (RPC, Indexing, Bridges, Oracles, Wallets, etc.) → shortlist and compare offers.

• Harden production access: open Performance → set monitoring/notifications → configure routing and failover.

• Need an RPC/Subgraphs right now: open API Management → use RPC/Subgraphs endpoints (details below).

• Key areas:

  • Monitoring

  • Notifications

  • Load balancer

  • Performance agreements

• Open: https://arbitrum.chain.love/configurations

API Management (RPC & Subgraphs)

This module is for accessing APIs (RPC/Subgraphs). If you’re evaluating providers or comparing options, start with the Toolbox section above.

RPC (JSON-RPC)

We host one JSON-RPC API endpoint for Arbitrum Mainnet:

• Archival Node: This node provides access to the entire blockchain history, starting from genesis, as is. You can learn more about its API here: RPC API. Only POST endpoints are supported.

Subgraphs (Indexing)

You can query your subgraphs using the following methods:

• By name: https://proxy.arbitrum.chain.love/subgraphs/name/<SUBGRAPH_NAME>

Mainnet

# Assuming the subgraph name is `arbitrum/test`
curl -X POST \
 -H "Content-Type: application/json" \
 -d '{"query":"query MyQuery {\r\n  jobs(first: 10) {\r\n    id\r\n  }\r\n}","variables":{}}' \
 "https://proxy.arbitrum.chain.love/subgraphs/name/arbitrum/test"
