Allium

Allium is an enterprise blockchain data platform that ingests raw onchain events from 150+ chains and converts them into clean, standardized, production-grade datasets—making blockchain data as queryable and reliable as traditional financial data infrastructure.

The Problem

Public blockchains are theoretically open, but their raw data is practically unusable for institutional work. Transaction logs are encoded, schemas vary by protocol, and the volume of noise—bot activity, wash trading, self-transfers—drowns out genuine economic signal. Allium's founders identified this gap directly: Ethan Chan, who studied AI at Stanford and built ML and data pipelines for Fortune 500 companies at Primer, recognized that "you have to control the data source" for analytics to be trustworthy. His co-founder Cheng Han Lee brought complementary depth from leading cloud and payments engineering at Poynt (processing billions in transactions) and building ad data infrastructure at Meta.

They founded Allium in 2021 with a clear mandate: build one canonical, auditable source of truth for onchain data.

How It Works

Allium's core engine indexes blockchain events at the node level, decodes them against 10,000+ protocol-specific schemas, and applies systematic methodology to separate genuine economic activity from noise. On the output side, the platform has filtered approximately $159 trillion in non-economic volume out of $176 trillion in unadjusted onchain transaction volume, arriving at a $17 trillion adjusted figure that institutional clients can trust for research, compliance, and market analysis.

Data is delivered through several purpose-built product layers:

• Allium Explorer: A hosted SQL interface where analysts can write custom queries across any supported chain without managing infrastructure.
• Allium Terminal: Pre-built dashboards surfacing who is transacting, where, and with what—geared toward analysts who need answers without writing queries.
• Allium AI: Natural language query interface that converts plain English into SQL, plus an MCP integration that lets AI agents query blockchain data programmatically.
• Datashares: Warehouse-native delivery that drops production-ready datasets directly into Snowflake, BigQuery, Databricks, S3, or GCS—removing the need to build and maintain custom indexers.
• Developer APIs: REST endpoints with 50–100ms response times for real-time application development.
• Datastreams: Event-driven pipelines delivered via Kafka, Google Pub/Sub, AWS SNS, or WebSocket for use cases requiring live blockchain event feeds.
• Beam: A product that lets teams configure custom-filtered realtime pipelines with transforms and deploy them in roughly 30 seconds.
• Allium Nodes: Managed node access for teams that need direct RPC infrastructure without operating their own validators.

Solana Coverage

Solana is a first-class citizen on Allium, with data indexed from the genesis block and coverage across 30+ on-chain protocols. The raw data layer captures blocks, transactions, instructions, inner instructions, and validator rewards. On top of that, Allium decodes and structures activity across asset transfers, SPL and SOL balances (with PnL calculations), DEX trades and aggregator trades (including Jupiter), liquidity events and positions, NFT trades and mints, lending events (loans, repayments, deposits, withdrawals), staking rewards, and validator and staker data.

Protocol coverage includes major Solana DeFi venues—Raydium, Orca, Meteora, Jupiter, Kamino—as well as NFT marketplaces Magic Eden and Tensor, with additional protocol schemas available on request. SPL2022 token standards are supported, and data can be formatted in double-entry accounting structures for finance teams that need audit-ready records. The Wallet API, which delivers pre-interpreted activity history for any set of wallets, added Solana support in early 2025 and expanded to cover full historical transaction activities, balances, DEX trades, and SPL transfers in 2026. Teams can also subscribe to a dedicated Solana DEX Trades Datastream for live post-trade data from venues like Raydium.

Clients and Use Cases

Allium's client roster spans the institutional spectrum. Visa and Standard Chartered use the platform for payments analytics and compliance. Coinbase, Phantom, and Uniswap run application workflows on Allium's APIs. Andreessen Horowitz's crypto division, Grayscale, and hedge funds access cleaned cross-chain data for research and portfolio analytics. DefiLlama sources TVL and protocol data from Allium. The U.S. Federal Reserve and Stanford have cited Allium data in published research. George Mason University's Future of Finance Lab has built academic papers on dollar dominance and perpetual futures markets using Allium datasets.

Traction and Funding

By mid-2026, Allium had grown to more than 150 enterprise clients and more than tenfold revenue growth since its Series A. In June 2026, the company raised a $40 million Series B led by Amplify Partners, with participation from Kleiner Perkins and Theory Ventures. The company employs 50+ engineers across New York, Singapore, and remote locations.

Independent recognition has tracked the growth: Allium ranked fifth among crypto and fintech companies on The Information's "50 Most Promising Startups of 2025," and appeared on The Generalist's Future 50 list in 2024 as one of the highest-potential companies under a $200 million valuation.

Ecosystem Fit

For Solana builders and analysts, Allium removes the most costly step in any data pipeline: indexing and decoding raw chain data. Teams building payment apps, trading analytics, compliance tools, or institutional research can access a full Solana data history—from genesis to the latest block—in the cloud environment they already use, without running their own RPC nodes or writing custom decoders. The breadth of cross-chain context also lets Solana-native applications benchmark activity against 150 other networks, a capability that has become particularly relevant as stablecoin and DeFi data informs institutional decision-making across ecosystems.
