Allium

Open a Visa dashboard. You're already reading Allium.

Somewhere right now a treasury analyst at a payments giant is watching stablecoins move in real time - billions of dollars settling across a dozen public blockchains, each with its own dialect, its own quirks, its own way of being almost-but-not-quite consistent. The numbers look effortless. They are not. Underneath that tidy chart sits Allium, the company that spends its days arguing with raw blockchain data so its customers never have to.

Allium is a blockchain data infrastructure company headquartered in New York, with a second home in Singapore. It takes the public ledgers of the crypto world - notoriously open, notoriously unreadable - and turns them into something a finance team can actually query. Visa, Stripe, Coinbase, Phantom, Grayscale and MetaMask are paying for it. That is an unusual guest list for a company most people have never heard of.

Blockchains promised transparency. What they delivered was honesty without legibility - every transaction visible, almost none of it readable. Allium's bet is that being able to see data and being able to use it are two entirely different businesses, and only one of them is worth paying for.

The ledger is public. The truth is buried.

Here is the inconvenient secret of blockchain data: it is all there, and it is all useless. A single transaction arrives as hex-encoded bytes referencing smart contracts you have never seen, denominated in tokens with eighteen decimal places, occasionally rewritten when a chain reorganizes itself and quietly changes its mind about what happened. Multiply that by 150 networks that agree on almost nothing, and you have an honest record that no human can read.

For years the standard answer was to hire a team of engineers to babble at the blockchain full-time - decoding contracts, normalizing tokens, handling reorgs, rebuilding pipelines every time a new chain launched. It was expensive, it was fragile, and it produced numbers nobody could fully trust. Auditors do not love "trust me, our internal script says so."

The problem compounds with stakes. When a bank reconciles on-chain mints and burns against its off-chain ledger, "approximately right" is not a category that exists. When a regulator asks where the money went, a screenshot of a block explorer does not constitute an answer. Someone had to make blockchain data boring - reliable, standardized, auditable. Boring is the hardest thing to build.

Two data engineers who'd already done this once

Ethan Chan and Cheng Han Lee did not come to crypto as believers; they came as plumbers. Both had spent years building real-time data and machine-learning pipelines at the kind of companies where pipelines breaking is a fireable offense - Meta, Poynt, Primer. Chan led machine-learning and data infrastructure at Primer; Lee ran payments and cloud systems at Meta and Poynt. They knew, in their bones, what well-behaved data was supposed to feel like.

So when they looked at blockchain data in late 2021, they did not see a religion. They saw a mess they recognized - and a market that would pay handsomely to never look at it again. The bet was contrarian in a quietly sensible way: while much of crypto chased tokens and speculation, Allium would build the unglamorous infrastructure layer underneath all of it. Pickaxes, not gold.

Field note: The company is named after the plant genus that includes onions and garlic - things defined entirely by their layers. Whether that was intentional commentary on blockchain data, the founders have wisely never confirmed.

One schema to rule the chaos

Allium ingests raw activity from 150+ chains, decodes thousands of smart contracts, handles the reorgs, normalizes the tokens, and hands it all back in a schema that is easy to query. The hard engineering disappears; what is left is a clean table and a fast answer. Customers can take that data however suits them.

The genius is in what the customer never touches. No hex. No reorg logic. No 3 a.m. page when a new chain ships a breaking change. Allium absorbs the entropy and ships the order.

A short history of making data behave

The receipts are the product

Infrastructure companies live or die by who trusts them, and Allium's customer list reads like a roll call of institutions that cannot afford to be wrong. Visa runs its public stablecoin dashboard on it. Stripe and large stablecoin issuers reconcile on-chain mints, burns and transfers against their off-chain ledgers with it. Coinbase, Phantom, Uniswap, Grayscale and MetaMask round out a list weighted heavily toward the people who get audited.

Why this chart matters: when the thing you measure grows 40x, the act of measuring it credibly becomes a business. Allium happened to be holding the ruler.

Behind the names sit petabytes of processed data and a streaming stack built with partners like Confluent and Snowflake. The numbers themselves became a marketing channel: in 2025, adjusted stablecoin transaction volume reportedly hit $10.9T - closing in on Visa's own $14.2T in annual payments. Allium had the figures because Allium had the pipes.

Make on-chain finance auditable

Allium's stated goal is to become "the system of record for on-chain finance." Strip the slogan and it means something concrete: a future where a stablecoin balance, a DeFi position or a wallet's history can be looked up and trusted the way a bank statement is trusted today. Not because someone vouches for it, but because the data is standardized, reconciled and reproducible.

The culture pushing this is deliberately intense - "Pro Athlete Mindset," "Extreme Ownership," "High Agency," "Strong Opinions, Loosely Held." Read uncharitably, it is startup boilerplate. Read in context, it is what you want from the people responsible for the numbers a payments network publishes to the world.

The plumbing decides what gets built

If stablecoins keep rivaling card networks, if tokenized assets move from pilot decks to balance sheets, if regulators keep asking sharper questions - then the bottleneck stops being the blockchain and starts being the ability to read it. Whoever owns that reading layer owns a quiet, durable position underneath the whole industry. Allium is making a serious run at being that layer.

The risk is the same as the opportunity: infrastructure is invisible until it fails, and competitors like Dune, Nansen, Flipside and Chainalysis are circling the same ground. Winning means being the default, not the alternative - the name nobody mentions because everyone assumes it.

So return to that treasury analyst, still watching stablecoins settle in real time. A few years ago that view did not exist; it would have taken a team of engineers and a leap of faith. Today it is a tab in a browser, refreshing quietly, trusted enough to publish. The chaos of 150 blockchains is still down there, exactly as messy as ever. Allium just put a clean pane of glass over it - and decided that selling the glass was the whole business.
