Basic plan
Best-effort delivery means messages are lost during outages or system downtime.
Best-effort delivery means messages are lost during outages or system downtime.
Subgraphs
Best-effort delivery means messages are Raw blockchain events require specialized knowledge to decode and query.
GraphQL adds complexity and learning curve.
Indexing costs scale exponentially with query volume, making production usage expensive.
Teams need blockchain expertise to maintain and troubleshoot.
Guaranteed delivery with enterprise message brokers (Kafka, Pub/Sub, SNS)
Decoded & enriched data with consistent schemas

Real-time, production-ready streams for every use case.

Push-based data streams for wallets, tokens, and trades.

Choose raw logs or enriched schemas

Stream raw blockchain logs or pre-enriched data — balances, DEX trades, NFT events, token transfers at your preferred level of processing.

Filter down to what matters

Subscribe by chain, schema, or entity to stream only the events you need.

Deliver to your stack

Push data to Kafka, Pub/Sub, or SNS. Websockets also available.

Trust production-grade accuracy

Rely on automatic reorg handling and consistency checks — we reconcile chain reorganizations so you don't have to.

Replay historical events on demand

Access historical messages when needed — retention policies ensure you never lose critical events.

Datastreams

Subscribe to full chain topics and process events in your infrastructure.

  1. Choose topics — ethereum.transactions, solana.dex_trades, etc.
  2. Connect your Kafka or Pub/Sub — Events flow automatically
  3. Build your processing — Filter, transform, route to your systems

Allium Beam

Beta

Build custom-filtered stream transformations — define filters and transforms in a UI, receive only what you need.

  1. Define your filters — Contract addresses, wallet set lookups (100K+ addresses), value thresholds
  2. Add transformations — Reshape data, extract fields, enrich events
  3. Choose your sink — Kafka, SNS, Pub/Sub, direct DB
  4. Deploy in 30 seconds — Visual builder or AI Beam Builder

Data Aggregators
Goldsky focuses on self-serve tools for custom indexers and raw event pipelines. Allium focuses on delivering analytics-ready data with zero maintenance.
Dashboards & Analytics
DeFiLlama focuses on aggregating and publishing high-level DeFi metrics. Allium focuses on delivering the underlying data so teams can build their own analytics.
RPC Providers
Helius is purpose-built for Solana RPC and real-time developer APIs. Allium is built for multi-chain analytics, decoded schemas, historical data, and enterprise data infrastructure beyond real-time APIs.
Dashboards & Analytics
Zerion is optimized for fast wallet data via APIs. Allium is built as a verified data platform that scales from APIs to streaming, SQL, and data warehouses as teams grow.
Dashboards & Analytics
Allium and rwa.xyz both cover tokenized real-world assets and stablecoins, but they are built for different jobs. rwa.xyz is a market data dashboard for tracking RWA supply and protocol metrics. Allium is data infrastructure for custom analysis, operational workflows, and institutional delivery.

FAQ

Should I use Datastreams or Beam?
Use Datastreams if you have streaming infrastructure and want full chain data with maximum control. Use Beam if you want custom-filtered stream transformations without building or maintaining real-time infrastructure — ideal for notifications, monitoring, and alerting.
Can I use both?
Yes. Some teams use Datastreams for analytics (full data to data lake) and Beam for user-facing features (custom-filtered streams for notifications).
What's the latency difference?
Datastreams delivers at P50 ~5 seconds. Beam delivers at P50 <2 seconds. Beam is faster because filtering and transformation happen at source through co-located processing.
How much infrastructure does Beam eliminate?
Beam eliminates downstream Kafka consumers, transformation pipelines, and filtering logic.
How much engineering time does Beam save?
Building custom streaming pipelines typically takes 3-6 months. Beam deploys in 30 seconds with a visual builder or AI Beam Builder.
Does Beam support my sink?
Beam supports Kafka, AWS SNS, Google Pub/Sub, and direct database sinks (ClickHouse, Postgres).
What kind of filters and transformations does Beam support?
Filters: contract address filtering, large wallet set lookups (100K+ addresses), value thresholds, event type selection. Transformations: data reshaping, field extraction, event enrichment — all defined in the UI.
Why Allium over Goldsky?
Goldsky Mirror is streaming-only. Allium gives you streaming plus Explorer, Datashares, APIs, and attribution data — all from the same standardized schemas. When multiple teams reference the same Allium data, switching creates coordination cost across finance, product, engineering, and compliance.
