Why
The post makes three claims, and only one of them can be checked this week. That is not a criticism — it is an advocacy piece and reads as one. But separating the three is the whole value of reading it carefully, because the checkable one happens to be the load-bearing one.
First claim: eighty million customers. Revolut having 80 million customers is not 80 million customers onboarded to Ethereum; it is an option on distribution, not distribution. The number that would settle it is the fraction who ever hold or move the token, and nobody publishes that for any consumer stablecoin integration. Until someone does, a user count is the size of the funnel's mouth. This catalogue has the same shape recorded in st-self-distribution, where the real figure was never the raise but the customers already inside the issuer's app.
Second claim: that a euro stablecoin validates neutral infrastructure. The more interesting question is why a euro stablecoin at all, because it is a different business from a dollar one. Dollar issuers earn on the reserve — short-dated Treasuries at whatever the front end pays. Euro reserves do not throw off the same yield, so issue it and earn the float is a thinner story in euros than in dollars, and something else has to justify the product: FX corridors, an EU-regulated e-money token that a euro-denominated customer base can actually be paid in, or simply that a bank-shaped company must denominate in its customers' currency. Which of those it is decides what the product becomes, and it is not stated. tokenized-money-banks is where the balance-sheet version of this question already lives.
Third claim, and the one worth working on: that dollars and euros now trade against each other with shared liquidity. That is a spread. If crossing EUR to USD on-chain costs several times what it costs interbank, the two assets coexist on one ledger without meaningfully trading, and composability has produced adjacency rather than a market. If the gap is small — or if it inverts at weekends, when the on-chain venue is open and the FX market is closed — that is a genuine and specific advantage, and it is the first concrete thing anyone could point at to support the settlement-layer argument.
Which is the honest reading. The excitement may well be warranted. But the entire financial world naturally wants to meet here is a claim that will be settled by spreads and depth, not by launches, and the spread is already observable.
How it works
Three claims, sorted
| Claim | Status | What would settle it |
|---|---|---|
| 80 million customers onboarded | Category error — Revolut's user count, not Ethereum's | Fraction who ever hold or move the token |
| A euro stablecoin validates neutral infrastructure | Unfalsifiable as stated | Why euro: FX corridors, EU e-money regime, or customer denomination — pick one |
| Dollars and euros trade against each other with shared liquidity | Measurable today | On-chain EUR/USD spread and depth, against interbank |
The measurement, in full
| Input | Where it comes from |
|---|---|
| Quoted depth at several sizes, euro and dollar stablecoin pools | Public on-chain state |
| Cost to cross between them at each size | Simulated swap against the same state |
| Interbank EUR/USD spread at the same moment, same notional | Standard FX reference |
| The same, sampled through a weekend | The interesting window — one venue open, one closed |
Output: how many times wider the on-chain crossing cost is. A single ratio, produced from public data, that either supports the shared-liquidity claim or shows it to be adjacency. And the weekend sample is where an honest advantage would show up first, since that is the one period a 24/7 ledger offers something interbank cannot.
Why the euro question is not a detail
| Motive for a euro stablecoin | What it implies about the product |
|---|---|
| Reserve income | Weak in euros — the yield that funds dollar issuers is not there |
| FX corridor economics | The product is a payments rail, and the spread above is its P&L |
| Regulatory fit — an EU e-money token | The reserve and redemption rules are set externally, not chosen |
| Customer denomination | The product exists because the customers are paid in euros, and no float story is needed |
The post does not say which, and the four lead to different products. Read with tokenized-money-banks, which prices the same choice from the issuer's balance sheet, and jurisdiction-decides-the-category, since an EU-regulated issuer is a regulatory position before it is a technical one.
The part that is genuinely new
Strip the advocacy and one fact remains worth watching: two major fiat currencies as bearer instruments on the same ledger, with no bank in the middle of the crossing. Whether that produces a market or two adjacent assets is exactly the sort of thing this catalogue exists to measure rather than assert — and unlike most claims here, this one does not need permission, a partner, or a licence to check.
