// In every reading
Supply, and how it moved
One reading per token and chain, plus the totals.
Supply
The total tokens in existence on that chain, from the contract itself.
24 hours
The net change in supply over the last day: issued minus redeemed.
7 days
The same over the last week, which smooths out single large days.
Totals
Every chain and token added together, so you see the whole picture at once.
// Coverage
What it reads
The two largest dollar stablecoins, on the chains where most of them live.
USDT
On Ethereum, Tron and Solana.
USDC
On Ethereum and Solana.
More chains
Added when we can read them as directly as these.
// How a reading is made
From the contract to the feed
No third-party dashboard sits in between.
- 1
Read
We ask each token contract for its total supply, through our own connections to each chain.
- 2
Keep
Each reading is stored with the time it was read, so the history can be checked later.
- 3
Compare
Each reading is set against the ones 24 hours and 7 days before it to give the net flow.
- 4
Publish
A new reading every minute, plus hourly and daily history.
Questions
- What does a net flow mean?
- When supply rises, more tokens were issued than redeemed. When it falls, more were redeemed. It does not say who did it or why.
- Why read the contracts directly?
- Because supply on a chain is a fact the chain itself records. Reading it there means our numbers do not depend on anyone else's dashboard.
- Does it count tokens bridged between chains twice?
- Each chain's own contract is read on its own, and the method page explains how the totals treat bridged tokens.
- Does it tell me what to trade?
- No. It shows how much stablecoin supply there is and how it changes. It is information, not advice.
