Cardano Stream
Your own live Cardano database. No node, no db-sync, no DevOps. BCA streams the full db-sync dataset into your own PostgreSQL instance over a VPN tunnel: near real-time, full SQL, on your own infrastructure.
-
Full
cardano-db-syncschema, replicated live via standard PostgreSQL logical replication - Saves ~64 GB RAM compute node and ongoing DevOps overhead vs. self-hosting a Cardano Node + db-sync
- Choice of source pipeline: mainnet + preprod + preview, or mainnet only
- Choice of geo-location: EU, US
- WireGuard VPN connection: encrypted, and monitored by BCA
- Feature levels: Team · Enterprise

Enterprise
Two independent streams into your own database, with a contractual SLA.
- 2 replication streams
- Geo-location per stream: combine freely (EU+EU, US+US, or EU+US)
- Source pipeline chosen per stream
- WireGuard VPN connections
- Full chain history from genesis
- SLA 99.9%
- Monthly upgrade window, staggered upgrades
- Prometheus endpoint integration
- Priority support
How it works
Choose mainnet + preprod + preview, or mainnet only, and whether your pipeline runs in the EU or US.
A dedicated, replication-scoped PostgreSQL credential set and a WireGuard configuration are generated for you, packaged as a ready-to-run Docker image.
docker-compose up.
Run the package on your own infrastructure. It brings up the WireGuard tunnel and your subscriber PostgreSQL, then starts the initial full sync from genesis.
Once the initial sync completes, every new block, transaction, and staking event streams in near real-time: standard SQL, no custom client required.

| Live replication stream | 1 stream (1 credential set) | 2 streams |
| Connection method | WireGuard VPN | WireGuard VPN |
| Pipeline geo-location | EU or US (choice at signup) | combine freely (EU+EU, US+US, or EU+US) |
| Source pipeline | A (mainnet, preprod, preview) or B (mainnet only) | A or B, per stream |
| Mainnet | ✓ | ✓ |
| Preprod / Preview | ✓ on pipeline A | ✓ on pipeline A |
| Monthly upgrade window | ✓ | ✓ |
| SLI metrics view | ✓ | ✓ |
| SLA | – | ✓ 99.9% |
| Prometheus monitoring integration | – | ✓ |
* Preprod and preview are included at no extra cost whenever the mainnet+preprod+preview source pipeline (A) is selected; not a paid add-on.
Connection Reliability
BCA actively monitors the WireGuard tunnel and acts on disconnects before they become your problem. Keep your subscriber database online; we track connection state continuously and step in if it lapses.
If it goes offline for an extended period:
2h disconnected → internal alert 24h disconnected → internal alert + customer notified 72h disconnected → subscription auto-disabled, replication slot dropped
Reconnecting after a 72h cutoff requires a fresh resync (full copy of the db again, not an incremental catch-up). Planning a longer maintenance window? Let us know in advance.
Built For
DApp Backends
Query the full db-sync schema directly with SQL: no REST wrapper, no endpoint limits
Analytics Platforms
JOIN Cardano on-chain data with your own internal datasets in the same database
Wallet & Staking Backends
Low-latency access to delegation, reward, and stake-address tables
Data Sovereignty & Compliance
Keep chain data on your own infrastructure; not hosted by BCA
Data Engineering Teams
Skip maintaining Cardano node & db-sync: save ~64 GB RAM and the ongoing upgrade burden
High-Availability Systems
Enterprise's two geo-redundant streams support active-active or active-passive failover
Resources
Requires PostgreSQL 16 (or compatible: Amazon Aurora PostgreSQL, Google Cloud SQL for PostgreSQL) and the ability to configure a logical replication subscriber connection. Full db-sync schema, ~650 GB+ and growing.
