Tetra Digital Group has deployed its Canadian-dollar stablecoin CADD on Solana, extending its availability beyond Ethereum, Base and Tempo. CADD is issued by Tetra Trust Company through CAD Digital Inc. and is backed 1:1 by Canadian-dollar reserves dedicated to redemption. Tetra positions the token for payments, transfers, treasury operations and settlement, including potential corporate and cross-border payment uses through a planned integration with Berkeley Payment Solutions. The expansion comes as BMO, CIBC, RBC, Scotiabank, TD and National Bank test tokenized deposits for interbank transactions. Unlike CADD, which circulates as a reserve-backed stablecoin on supported blockchains, tokenized deposits represent liabilities held within the commercial banking system.
