Stablecoin weekly: only $188M leaves, but $1.09B USDT shifts to Tron (2026)

The latest seven-day snapshot is only mildly negative: USDT + USDC + DAI fell $187.7M to $259.946B. 1 The small headline masks a large rail change. USDT added $1.091B on Tron while losing $789.9M on Ethereum and $399.7M on Solana. That is a balance shift inside a nearly flat aggregate, not a clean injection of new buying power.

Snapshot: August 12, 2026, 08:00 (UTC-05:00). DeFiLlama's current and circulatingPrevWeek fields are compared below; rounded figures may not reconcile. The market prices were refreshed at about 08:02–08:03 (UTC-05:00), a few minutes after the scheduled cutoff.

Bottom line

Asset	Current supply	Previous-week supply	7-day change	Change
USDT	$182.987B	$183.064B	-$76.0M	-0.04%
USDC	$72.180B	$72.270B	-$90.6M	-0.13%
DAI	$4.779B	$4.800B	-$21.1M	-0.44%
USDT + USDC + DAI	$259.946B	$260.134B	-$187.7M	-0.07%
than the prior issue's $1.351B decline. All three assets are lower, but the direction is not uniform at chain level. The practical read is a softly defensive aggregate with a strong USDT relocation toward Tron.

Circle's own dashboard showed $72.1B USDC in circulation as of August 10, close to DeFiLlama's $72.180B snapshot. The two readings use different timestamps, so the comparison is a cross-check, not a second weekly series. 2

The chain map: USDT moves to Tron, USDC reverses

The table includes the major chains requested by the channel and the largest movers returned by the endpoint. Other chains is the residual of the full chain list, not a bridge-flow estimate. Chains with no non-zero record are omitted.

USDT

Chain	Current supply	7-day change
Tron	$90.632B	+$1.091B
Ethereum	$74.012B	-$789.9M
Solana	$2.958B	-$399.7M
BSC	$9.176B	+$0.1M
Aptos	$976.1M	+$89.9M
Avalanche	$382.3M	+$69.9M
Plasma	$634.0M	-$130.8M
Polygon	$822.1M	-$19.6M
Arbitrum	$820.4M	-$2.0M
Other chains	$2.467B	+$16.6M

USDT's total supply fell only $76.0M because Tron's gain offset most of the Ethereum and Solana losses. The shift is large enough to matter, but endpoint balances cannot tell us whether tokens crossed a bridge, moved through treasury inventory, or changed hands inside applications. It should not be labeled a bridge inflow without pair-level flow data.

USDC

Chain	Current supply	7-day change
Ethereum	$46.325B	+$207.2M
Solana	$6.913B	-$250.7M
Hyperliquid L1	$6.022B	-$49.5M
Base	$4.178B	-$7.8M
Arbitrum	$2.267B	+$24.5M
Polygon	$1.602B	-$44.6M
BSC	$1.581B	+$0.0M
Stellar	$405.6M	+$67.5M
Avalanche	$401.8M	-$41.2M
Aptos	$225.0M	-$5.5M
Other chains	$2.232B	+$9.4M

USDC has reversed the most visible part of last week's pattern. Ethereum is now up $207.2M after last week's decline, while Solana is down $250.7M after last week's increase. The asset still lost $90.6M overall, so Ethereum's recovery is not yet broad expansion.

DAI

Chain	Current supply	7-day change
Ethereum	$4.105B	-$13.9M
Polygon	$538.4M	-$7.4M
BSC	$31.1M	+$0.0M
Arbitrum	$18.8M	+$0.2M
Avalanche	$10.7M	+$0.0M
Other chains	$74.4M	+$0.1M

DAI fell $21.1M, with nearly all of the decline coming from Ethereum and Polygon. It is too small a move to change the Big-3 signal. 1

Issuer events: a large Tether reset, then a Solana USDC mint

Whale Alert recorded a $1.750B USDT burn at Tether Treasury on Ethereum and a $1.000B USDT mint at Tether Treasury on Tron within minutes on August 10. The event-level net is -$750M, but the two transactions occurred on different chains and do not by themselves prove a $750M reduction in end-user liquidity. 3 4

A separate 250M USDC mint at USDC Treasury on Solana was posted on August 11. This is issuer inventory evidence. The weekly endpoint, however, shows Solana USDC down $250.7M, so the mint cannot be counted as net new liquidity without following its later deployment and reconciling the endpoint balances. 5

The largest non-issuer events located before the cutoff were a 192.296M USDC transfer from an unknown whale to Aave and a 216.742M USDT transfer from an unknown wallet to OKX. These are categorized only as unknown-wallet transfers. Neither is a mint or burn, and neither proves that funds are newly available for spot buying. 6 7

No timestamped, comparable Maker/Sky DAI mint-and-burn ledger was verified for this window. The events above are therefore a selected alert set, not a complete whale-flow census.

Market cross-check

Asset / indicator	Snapshot	7-day or latest change
BTC	$64,049.29	-0.39% over 7 days; -0.14% over 24 hours
ETH	$1,906.80	+1.82% over 7 days; +1.06% over 24 hours
Crypto Fear & Greed	27, Fear	Previous reading: 29, Fear

BTC is slightly lower over seven days while ETH is higher. Both were positive over the prior six hours in the API snapshot, but the small price rebound has not coincided with broad Big-3 stablecoin growth. Sentiment remains Fear rather than Extreme Fear, but it has not improved from the previous reading. 8 9 10

What the snapshot can—and cannot—say

The clearest positive signal is not aggregate growth. It is USDT's $1.091B increase on Tron, paired with a large Tether Treasury mint on that chain. The clearest negative signal is that Ethereum and Solana together lost $1.190B of USDT, while USDC also lost $90.6M overall.

That combination points to internal routing and inventory management more strongly than to fresh market-wide buying power. A trader can reasonably watch Tron USDT for confirmation, but should not treat the chain move as a bridge inflow or assume the Treasury mint reached exchanges and end users.

Three requested questions remain open:

Are stablecoins growing in aggregate? No. The Big-3 fell $187.7M week over week.
Is capital concentrating on a rail? Yes. The strongest balance change is USDT on Tron, while USDC moved back toward Ethereum and away from Solana.
Is that capital available to buy risk assets? Not established. The issuer and wallet alerts show operations and transfers, not end-user demand.

Pair-by-pair bridge flows were not available: the DeFiLlama Bridges endpoint returned a paid-plan prompt rather than a usable seven-day table. A comparable public series for combined USDT + USDC balances held on major exchanges was also not verified. 11

The next confirmation to watch is whether Tron's USDT balance holds its gain while Ethereum stops losing supply. If both happen, the move may be a durable venue rotation. If Tron gives the balance back, this week's largest flow will look more like temporary treasury or inventory positioning than a new liquidity channel.

Method note: Supply figures use DeFiLlama's asset and chain snapshots. Issuer and wallet events come from Whale Alert's public event records and are not treated as proof of end-user demand. Market figures use the linked public APIs. All displayed times are in UTC-05:00.
