Frax and DFB launch six stablecoin FX pools on Base's Aerodrome
Frax opens six currency pools against frxUSD
Frax announced a six-currency foreign-exchange lineup on Aerodrome, a trading platform on the Base network, on Oct. 19. The pools let traders swap stablecoins tied to local currencies directly against Frax's dollar token, frxUSD.
A stablecoin is a crypto token designed to hold a steady value, usually by tracking a government currency. In these pools, traders exchange those currency-pegged tokens instead of bank-account balances.
The lineup pairs frxUSD with BRZ, CADD, tGBP, IDRX, ZARP and AUDF. Those tokens track the Brazilian real, Canadian dollar, British pound, Indonesian rupiah, South African rand and Australian dollar. Frax said "six local currency stablecoins trade against frxUSD" and named DFB as a collaborator.
How much the new pools hold
- The six pools held about $241,000 in combined liquidity, based on The Defiant's calculation from a GeckoTerminal snapshot taken Oct. 19 at 12:28 p.m. ET.
- Trading across the pools was roughly $20,000 over the 24 hours ending at that snapshot.
- IDRX had the largest pool at about $79,000, and it traded about $5,901 in 24 hours.
- CADD led 24-hour trading at about $6,941, followed by tGBP at about $6,194.
- The Australian-dollar pool (AUDF) traded about $92 and the rand pool (ZARP) about $160. Both were under $200.
- The BRZ pool traded about $770.
Aerodrome's interface lists these foreign-exchange markets as concentrated-liquidity pools. The reported liquidity figures measure total assets in each pool, not the quoted depth available for a single order.
A model already running on Polygon
The Base lineup repeats a setup already used on Polygon. The Defiant reported in April that Polygon, Frax, Curve and DFB had launched pools using frxUSD as the shared dollar pairing, with Polygon describing Curve's FXSwap as the exchange infrastructure.
The token lists differ. The Base lineup includes Canadian-dollar and rand tokens, while the earlier Polygon lineup included KRWQ, a Korean won token, and USDT alongside BRZ, IDRX, tGBP and AUDF.
Liquidity also differs by venue. Curve's official pool data, retrieved Oct. 19 at 12:29 p.m. ET, put its Polygon BRZ/frxUSD pool at about $373,000, compared with about $19,700 in the matching Aerodrome pool in the GeckoTerminal snapshot.
What is confirmed
Frax publicly announced the six-pool FX lineup on Aerodrome on Base on Oct. 19, and DFB was named as a collaborator. The pool names, the currencies they track and the liquidity and volume figures come from the GeckoTerminal data cited by The Defiant. The earlier Polygon deployment with Frax, Curve and DFB is documented in prior reporting and in Polygon's own description.
What is still unclear
The sources do not explain why liquidity and trading activity are so much lower on Base and Aerodrome than on Polygon, nor do they say whether those levels are expected to change. No timeline, targets or incentives for the new pools were given.
Why this matters
The pools create another venue where currency-pegged tokens can be traded against a dollar token on-chain, rather than through bank accounts. The comparison with Polygon shows the same kind of market can carry very different amounts of liquidity depending on where it runs.
