# Exchange stablecoin holdings and netflow

Stablecoins held in the on-chain wallets of 8 exchanges on 31 October 2026, with 7-day and 30-day inflow, outflow and netflow, from the Stablecoin Scanner (ACHIVX).

This page shows the stablecoins the scanner reads in each exchange's own on-chain wallets, and the stablecoins that flowed into and out of the exchange's addresses. These are on-chain measurements, not reserves.

Binance is not shown (as of 1 November 2026): a security incident it reported since 29 October 2026 is still open, and on-chain figures for it would be hard to read in that period. Its figures return here when the incident is closed.

## Flows, 30 days

Inflow enters the exchange's address set, outflow leaves it; a transfer inside the set (a deposit swept to a hot wallet) is in neither.

CoinEx: coverage is thin (30-day inflow under US$50 m in the wallets the scanner can attribute), so its holdings and flows are not shown.

HTX: coverage is thin (30-day inflow under US$50 m in the wallets the scanner can attribute), so its holdings and flows are not shown.

## How these figures are made

- **Organic, not raw.** Settlement figures are the scanner's organic figures, with round trips and bot churn removed. Raw settlement volume is not printed, and no field the scanner marks as overflowed is used.
- **Coverage: 7 networks** (Arbitrum, BNB Chain, Base, Ethereum, Optimism, Solana, Tron). Networks, coins and wallets the scanner does not cover have no figures here.
- **Read at build time.** Figures are read from the [Stablecoin Scanner (ACHIVX)](https://stablescan.achivx.com/) when this site is built, not live in your browser. Each row gives its window, the scanner's build date and the scanner page it comes from.
- **Not a reserve or solvency claim.** Exchange and bridge balances are on-chain reads of the wallets the scanner can attribute: a floor of their on-chain stablecoins, not their reserves or liabilities.
- Scanner methodology version: `stablscan-methodology-v0.6.0`.
