The chain data you need, in your database, backed by a world-class backend. Getting on-chain data into your database is now the easy part via @graphprotocol's The Graph Market. Hosted Sinks is a fully managed Substreams-sink-as-a-service. You point it at a Substreams package and a database, click Deploy, and we run it for you, at scale, securely, with zero ops on your side. Chain data to your tables, live, in minutes, then query it with the SQL tools you already know. --- What it does Bring your Substreams package, pick PostgreSQL or ClickHouse, and hit Deploy. That's it. Fresh chain data starts streaming into your tables, and we keep it running, backed by our highly-available and highly-reliable distributed infrastructure. Running a different kind of sink? Let us know so we can prioritize it! Transactional data for your app, columnar analytics for your dashboards, your choice. Works on all chains available on The Graph Market: Ethereum, Base, Solana, and beyond. No new runtime on your infrastructure, no blockchain plumbing: your Substreams package maps protobuf straight into relational tables, and you read it back with plain SQL. You already have a database, let us connect and fill it for you. --- How your team benefits Spin up in minutes, not sprints. Deploy, start, stop, and delete on demand — all self-service from the portal. No infrastructure to provision. Always correct, fork-aware. Substreams tracks the canonical chain and signals reorgs automatically, so chain reorgs never leave sheared or stale data behind. Inserts, updates, and upserts keep mutable data current. No manual cleanup. Update without downtime. Edit your package or config in place and we roll it out gracefully. Need a clean slate? Reset and re-sync from your start block. Secrets stay secret. Your database credentials live in HashiCorp Vault, never in code or config. Injected at runtime, with built-in disaster-recovery export/import. Multi-tenant by design. Every deployment is isolated to your organization: strict, enterprise-grade separation out of the box. Full visibility. Live status, per-instance health, and a complete deployment history — created, scaled, updated, restarted — all in the dashboard. --- What does it cost Billing is the same as it currently is, pay only for the data coming out of your Substreams. For the next 6 months, we’ll manage the sink for free. After this initial period, each sink will incur a negligible cost per month, confirmed before billing begins. The bottom line Stop staffing a platform team to move blockchain data into a database. Hosted Sinks abstracts away the credential management, the scaling, and the re-sync headaches and gives you back a simple form and a Deploy button.

If you build on Substreams, you've been getting faster data. We moved our reader nodes to @OVHcloud Bare Metal — 2-3x lower blockchain head latency, uptime measured in months, and faster catch-up on demanding chains like Solana and Base. Less waiting, more building. ovhcloud.com/en-ca/case-stud…
