What Is Onchain FX?

What Onchain FX Means

Onchain FX is a foreign-exchange conversion that settles on a blockchain by swapping two stablecoins denominated in different currencies. Instead of routing a currency trade through correspondent banks, a business converts one tokenized currency into another inside a liquidity pool, with the rate and settlement recorded onchain in minutes.

“there's a lot of opportunity for stable Canadian stablecoins domestically first and foremost, and then the second piece that we are seeing is cross-border a lot of activity”

— Didier Lavallee, Founder & CEO of Tetra Digital Group

The precondition is a supply of single-currency stablecoins beyond the US dollar. A Canadian-dollar stablecoin traded against a dollar stablecoin is, in effect, a CAD/USD trade that never touches the traditional FX system. Tetra Digital Group issued one of the first Canadian-dollar stablecoins, and its founder frames the demand in two parts.

How a Cross-Border Trade Works Onchain

The mechanics are concrete. A Canadian company holding a CAD stablecoin routes it through a liquidity pool that pairs it against a dollar stablecoin, receives the dollar token, and hands that to a US-side provider to off-ramp into dollars. The Canadian side keeps its own currency until the moment of conversion; the US side ends up with the dollars it actually wants.

“You can load a domestic pair, so CAD pair. You hit a liquidity pool, you convert into $1 token.”

— Didier Lavallee, Founder & CEO of Tetra Digital Group

Why It Undercuts a Bank's FX Desk

The case for onchain FX is cost and speed. A stablecoin-to-stablecoin swap removes the layers of intermediaries that each charge a spread on a cross-border payment. For the Canada-US corridor today, participants report the onchain leg is already cheaper and faster than the bank alternative, even before liquidity deepens.

“That conversion is already cheaper than a traditional FX leg that a financial institution would would charge you”

— Didier Lavallee, Founder & CEO of Tetra Digital Group

Corporate Treasury Is the First Real Use Case

The clearest demand is internal corporate treasury: large companies moving money between their own entities across borders. In July 2026, Hyundai ran its first live cross-border treasury transfer, moving $20,000 from its US entity to its Mexico entity by converting dollars into USDT and back. The transfer took about seven minutes end to end, against three to four hours through correspondent banking.

The pull is strongest where the traditional rails are worst. Roughly 80% of Canadian organizations trade with US counterparts, and that flow is slow, opaque, and often T+2 or T+3 — exactly the kind of low-value, high-frequency movement onchain settlement is suited to.

The Liquidity Problem

The honest constraint is liquidity. The pools that pair a local-currency stablecoin against a dollar token are thin, so onchain FX works well for smaller transfers but cannot yet absorb the hundreds of millions a large corporate treasury moves. Velocity, which raised a $30 million Series A for stablecoin payments, argues the depth will come from local currencies converting into dollar-backed tokens rather than from direct exotic pairs.

“your primary source of liquidity is going to come from native or local currencies moving into OUSD, USDC, USDT”

— Eric Queathem, Founder & CEO of Velocity

That is why supply builds around the dollar stablecoins first. Velocity connects to 22 liquidity partners to trade local currencies into dollar-backed tokens, and sees little momentum yet for a Canadian-dollar token trading directly into, say, a euro stablecoin.

Where Banks Fit

In thin corridors, someone has to take the other side of the trade. When there is no onchain demand for a local currency, the only way to close the loop is an off-chain FX trade with a local bank — which points to where the existing FX industry enters. The banks that run FX desks today are the natural liquidity providers as volume grows into non-major corridors.

“the only way you solve that is you go to a local bank and you try to do a an off chain FX trade”

— Eric Queathem, Founder & CEO of Velocity

• Non-dollar stablecoins are the missing leg. Onchain FX needs single-currency stablecoins beyond the dollar. Canada is roughly 2% of global GDP but a G7 FX pair worth about 6% of global money flows (Episode 92).
• Cost and speed already win; liquidity lags. Hyundai moved $20,000 from its US to its Mexico entity in about seven minutes versus three to four hours via correspondent banking, but pools are still too thin for large transfers (Episode 92).
• Corporate treasury leads adoption. About 80% of Canadian organizations trade with the US over slow, opaque T+2/T+3 rails — the low-risk, high-frequency flow onchain FX targets first (Episode 92).
• Banks become the FX counterparty. In non-major corridors the only off-ramp is a local-bank FX trade, so the incumbents running FX desks today are the natural onchain liquidity providers (Episode 92).
