# Chain concentration is now the dominant stablecoin risk

Published: 2026-01-21 · usd.net research

> The same ticker on two chains can be two entirely different credit exposures. Bridged supply inherits the bridge's security, not the issuer's balance sheet.

## Canonical vs bridged

Canonical issuance means the issuer mints natively on that chain and will redeem it. Bridged issuance means a wrapper contract holds the canonical token elsewhere and mints a representation. If the bridge is compromised, the representation goes to zero while the issuer's reserves remain untouched — and unavailable to you.

Every chain page on this site shows the split, because it changes what you actually own.


## Where the dollars actually sit

Supply is heavily concentrated on a small number of chains, with Tron dominating payment flow and Ethereum dominating collateral. Newer high-throughput chains are gaining share fast, and almost all of that growth arrives bridged before it arrives canonical.


## What to do about it

Treat chain exposure as a line item. Cap bridged supply as a share of total holdings, prefer canonical issuance for anything held longer than a settlement cycle, and check the split before you move size onto a new chain.
