Canada's regulated stablecoin adds Solana. The category has under 1,000 users

Tetra Digital Group put its Canadian-dollar stablecoin on Solana on 23 September, making it the fourth chain after Ethereum, Base and Tempo. CADD carries an approval from Alberta Treasury Board and Finance and is issued by Tetra Trust Company through its agent CAD Digital Inc. The category it joins has fewer than a thousand active users a month.

“Each token is backed on a 1:1 basis by Canadian-dollar reserves and can be used for payments, transfers, treasury operations and settlement.”

Stablecoins backed by US dollars hold 99.76% of supply against 0.24% for everything else, which is roughly $316bn against $2bn, a gap of 158 times. Inside that thin 0.24% the split runs like this:

• Euro-pegged coins hold about 80% of the non-dollar segment, roughly $635m at the end of June.
• Brazilian real takes about 10%, the Japanese yen about 8%.
• That leaves near 2% for every other currency combined, the Canadian dollar included: on the order of $40m.
• Tetra does not publish CADD's circulating supply, so its share of that residual is unknown.

Canada clears about $424bn every business day, and its retail payments still run on batch rails. Tetra has built the regulated track before the traffic exists, which is the right order to build in. It also means the news here is the permission, and the volume is still ahead.

What Alberta approved

Alberta approved an issuer, not a ticker. Reserves sit in trust and are dedicated to redemption alone, and the shareholder list is Canadian finance and commerce: Shopify, Wealthsimple, National Bank of Canada, ATB Financial, Purpose Unlimited and Shakepay, with Urbana Corporation holding the majority. Tetra claims a first for a Canadian-dollar stablecoin issued by a regulated financial institution, and the qualifier carries the claim: Canadian-dollar tokens existed before this one.

The distinction became practical the same week. Tetra warned users that copycat CADD tokens were appearing on the permissionless network, which is what a regulated issuer inherits when it ships onto a chain anyone can deploy to. Solana is where Tetra wants the payment volume, and the Solana Foundation has been staffing up for payments after $5trn of stablecoin throughput. The openness that makes the chain useful leaves the ticker unprotected.

Whose debt backs a stablecoin

There is one more thing a Canadian-dollar reserve changes. We measured this week that the largest stablecoin issuers now rank among the top 20 holders of US government debt, because dollar tokens are backed by Treasuries and Washington wants more of that. CADD is backed by Canadian dollars held in trust, so every unit minted is a unit of reserve demand pointed somewhere else. At the scale involved this is arithmetic rather than policy.

Whether the traffic arrives is the only open question, and there is a template for how this goes wrong. Singapore wrote a stablecoin law and ended up protecting a local coin 254 times smaller than the dollar coin trading beside it. Tetra has the regulator, the reserves and the shareholders. What it does not have yet is a thousand people a month.

Informational material, not investment advice. Tetra has not published CADD's supply, and the currency-split figures are market estimates from different months, so the residual in the third bullet is arithmetic rather than a reported number.
