Arc Mainnet is live. Arc launches as the Economic OS for the internet: an open platform for global markets, real-time value movement, tokenized assets, and agentic economic activity. Arc is more than a blockchain. It launches as a full-stack financial platform with assets, applications, interoperability, developer infrastructure, and Circle platform services live from day one. Arc delivers USDC as native gas, deterministic sub-second finality, EVM compatibility, and institutional validators. It integrates with Arc Studio, App Kits, Arc Portal, Circle Agent Stack, CCTP, Gateway, CPN, and StableFX. A complete economic platform at genesis. Arc launches with infrastructure for: → Agentic economic workflows → Lending and borrowing → Trading and liquidity → Onchain FX → Payments and settlement → Tokenized assets → Exchanges, wallets, custody, compliance, data, and developer tooling 190+ institutional and ecosystem builders are building across Arc.

Earlier this year, The Graph Foundation published the Technical Roadmap, Part 1 of a two-part series on the future of The Graph. Here’s Part 2: the official announcement of the Foundation’s new mandate, and how the Foundation will bring that roadmap to life.

Prediction markets are booming. $150B+ in cumulative volume. Every market, dashboard, and trading agent built on that runs on indexed onchain data. For Polymarket, it's already indexed on The Graph. Query it with Subgraphs. Stream it with Substreams. Or call the Token API. Read more:

The Graph is excited to be part of @ETHGlobal's ETHOnline hackathon: $15,000 across two tracks at ETHOnline: Best AI Project on The Graph (net-new and continuity pools) and Best Use of Composable or Standardized Graph Products. Live data only; mocked or static datasets do not qualify. Tracks and rules:

Hosted Sinks can now serve your Substreams data over a read-only GraphQL API and console. Powered by Hasura Auto-tracks your tables Just one checkbox to enable. Outgrowing a Subgraph? Taking the next step to Substreams no longer means giving up your GraphQL query layer.

🌐 ETHOnline Prizes: @graphprotocol ∙ $15,000 Build with live blockchain data: → Composable or Standardized Graph Products: $5K → AI Tooling or Use Case, From Scratch: $5K → AI Tooling or Use Case (Continuity): $5K Sep 4-16 •

Hosted Stores are live on The Graph Market. Substreams turns raw chain data into structured output. But when a module needs to look something up mid-stream (an off-chain price, token metadata, an address→owner map), you were stuck recomputing it in every pipeline or running your own key/value service that stays correct through reorgs. Hosted Stores removes that. It's a managed, block-aware key/value store StreamingFast runs for you: • Keys = raw bytes. Values = your protobuf messages. • Every read targets a block and stays in sync with the stream, backfills included. • Reachable over gRPC, or as a foundational-store input in any Substreams module. Two ways to fill it: → Remote feed: your service pushes data in over gRPC. Good for off-chain price feeds, allowlists, identity data. → Substreams feed: a package populates it from chain data. Compute token metadata or a pool registry once, reuse it across every pipeline. It joins Hosted Sinks under Hosted Services, the managed side of Substreams. Sinks push data OUT to your database. Stores hold data you look UP inside your pipelines. You operate neither. Beta. Works end to end today. Blog: Docs + feedback:

In 2025, 15.2% of indexing rewards on The Graph went to Indexers serving little to no queries. The Rewards Eligibility Oracle changes that and it just went live. Same issuance, better allocation. Learn more below:
