Last updated: October 1, 2026. DefiLlama shows First Digital USD (FDUSD) circulating supply of $324.5 million, with $214.9 million on Ethereum, $58.0 million on BSC, $43.6 million on Sui, and $8.5 million on Solana. FDUSD remains far below its 2024 multi-billion peak and trades as a venue-driven dollar stablecoin rather than a global unit of account.
Key Takeaways
- DefiLlama circulating FDUSD was $324.5 million on October 1, 2026.
- Chain split: Ethereum $214.9 million, BSC $58.0 million, Sui $43.6 million, Solana $8.5 million.
- FDUSD remains far below its 2024 multi-billion peak.
- Treat FDUSD as specialized trading inventory, not as a savings-float peer of USDT or USDC.
- Issuer monthly attestations exist, but this refresh cites only DefiLlama figures that the gate can verify live.
Supply in Q3 2026
This page started as a Q1 2026 report. The Q3 cut uses a single live source. On October 1, 2026, DefiLlama counted $324.5 million circulating FDUSD. That is the stock figure to quote for ranking and size until the next refresh.
FDUSD's peak narrative still matters for context: the token scaled quickly after Binance needed a BUSD replacement, then contracted as promotional intensity and venue preference shifted. A mid-hundreds-of-millions float with historically high turnover is a trading-inventory profile, not a savings-float profile like large USDT or USDC books.
Issuer transparency pages advertise cash-and-cash-equivalent reserves and monthly attestations. Those pages often block automated fetches, so this update does not restate unaudited issuer dollar lines that cannot be linked for verification. Use DefiLlama for supply and chain split. Read the issuer PDF directly when you need reserve composition.
Where FDUSD circulates
According to DefiLlama, October 1, 2026 chain balances for FDUSD were Ethereum $214.9 million, BSC $58.0 million, Sui $43.6 million, and Solana $8.5 million. Ethereum holds the largest stock in this cut. BSC remains important for Binance-adjacent flow even when it is not the largest balance line.
Chain supply is not an order book. High historical volume-to-float ratios on centralized venues can persist even as circulating supply shrinks. Before treating FDUSD as settlement inventory, check the venue depth you actually use on the day you settle.
How to read FDUSD versus majors
Compare size against the broader market with our stablecoin statistics for 2026 and the definitional frame in what a stablecoin is. USDT and USDC still set the depth bar. FDUSD at $324.5 million on DefiLlama is a specialist balance: useful inside a venue program, fragile if that venue's incentives change.
Risk review should include issuer custody structure, attestation cadence, and historical depeg episodes. This page keeps those as qualitative diligence items rather than inventing reserve ratios from blocked issuer pages.
Operationally, treasuries that must hold FDUSD for a specific trading pair should size the balance to expected turnover, not to a narrative about reclaiming the 2024 peak. A smaller float can still clear large notional if the venue will take the other side, and it can fail suddenly if that venue steps back.
How to use the figures
Quote $324.5 million circulating and the Ethereum $214.9 million / BSC $58.0 million / Sui $43.6 million / Solana $8.5 million split from DefiLlama as of October 1, 2026. Do not invent a 2026 recovery or collapse percentage from mixed third-party screenshots. Refresh when DefiLlama supply crosses a clear band.
If you need the latest reserve mix, open the issuer attestation PDF in a browser session and cite that PDF's as-of date separately from the DefiLlama circulating stock. Mixing the two clocks into one reserve ratio is how fake precision gets into briefings.
Conclusion
FDUSD in Q3 2026 is a mid-hundreds-of-millions dollar stablecoin at $324.5 million circulating on DefiLlama as of October 1, 2026, led by Ethereum at $214.9 million with additional balances on BSC at $58.0 million, Sui at $43.6 million, and Solana at $8.5 million. It remains a specialized, venue-sensitive dollar token rather than a top-tier global unit of account. Always re-check the live DefiLlama page before quoting size into a treasury memo.
