Fireblocks has set out its role as the operational layer beneath the Cari Network, a 24/7 inter-bank tokenised deposit system built by chartered US banks — but the part worth reading twice is the instrument, not the plumbing. Each Cari token records a US dollar deposit that stays on the issuing bank’s balance sheet. That one choice puts tokenised deposits in a different accounting, insurance and supervisory category from a stablecoin, whose reserves sit off the issuer’s balance sheet. The two are routinely discussed as competing digital dollars; they are not the same kind of liability at all.
The consequences run in four directions at once. A deposit on a bank’s books is eligible for FDIC insurance up to applicable limits, can pay interest, is treated as a cash equivalent for corporate accounting, and never leaves the prudential perimeter the bank is already examined under. A stablecoin balance delivers none of those by default. One detail also deserves flagging early: the scale figure Fireblocks published on August 10, 2026 — more than 30 banks committed, another 40 in active discussions, “a combined network and pipeline of more than $10 trillion in assets” — is the same figure Cari itself published on July 2, 2026. Five weeks apart, the disclosed pipeline has not moved.
What Fireblocks actually supplies
Per the August 10 post, Fireblocks provides wallet infrastructure assigned to each bank user and organisation, plus role-based access controls “configurable down to individual smart contract functions.” Cari wrote the smart contracts in-house, including the mint, burn and transfer calls that move the tokens, while ZKsync’s Prividium, built by Matter Labs, supplies the private, EVM-compatible Layer 2 (L2) the network runs on. Fireblocks states that Cari provisions and manages the Fireblocks infrastructure as part of membership, so member banks are not standing up a digital asset stack themselves — a materially different proposition from the proprietary chains money-centre banks have been building.
Six design partner banks are named: First Horizon, Huntington, KeyBank, M&T Bank, Old National Bank and SouthState Bank. Cari’s July disclosure added ten further joiners, among them ConnectOne Bank, Glacier Bank, MidFirst Bank and Raymond James Bank. The network has been endorsed by the Mid-Size Bank Coalition of America and has joined the American Bankers Association’s Premier Partner Network. This is mid-tier and regional US banking organising a collective answer to deposit displacement rather than absorbing the build cost alone — the same logic behind the JPMorgan and Citi tokenised deposit effort and the Swift shared ledger now piloting with 17 banks.
Who is on the record, and who is not
The Fireblocks post is bylined by Neil Chopra, Head of Strategy and Business Development, Americas at Fireblocks, and carries no quote from Cari or any participating bank. Chopra frames it bluntly: “That is the inter-bank digital asset gap. It is both a speed and infrastructure gap.” The attributable bank-side commentary comes from Cari’s July release. “Cari was founded on a simple belief: as money becomes increasingly digital, banks should continue to play the central role in issuing it, governing it, and serving the customers who rely on it,” said Gene Ludwig, Founder and CEO at Cari — a former Comptroller of the Currency, which explains much about how the network has been pitched to supervisors.
Distribution is the more interesting disclosure. “Through our correspondent banking platform, SouthState supports more than 1,300 financial institutions nationwide,” said Steve Young, Chief Strategy Officer at SouthState Bank, in the same release. Correspondent relationships are how a network of 30 reaches several hundred without onboarding each one directly.
What the source does not establish
Three cautions. First, “committed to join” and “in active discussions” are not the same as live and settling; Fireblocks describes the design partners as working towards production “later this year,” which means nothing was in production on August 10. Second, the $10 trillion figure is the combined assets of participating and prospective institutions, not deposits tokenised on the network — the on-chain balance has not been disclosed at all. Third, a consortium rail is worth exactly what its members’ go-live decisions are worth, and a network with roughly 70 nominal participants and no production volume is a distribution promise, not yet a settlement system.
For custodians and brokers, the practical read is that the counterparty stack is already familiar: banks running Fireblocks for custody and institutional wallet operations have a shorter integration path in — which is why Fireblocks is positioning Cari as an entry point to its wider platform rather than a standalone deployment. The unresolved question is how these instruments are treated once they cross borders, where rulebooks still diverge sharply. Watch for the first disclosed production transfer and a tokenised balance figure. Until one appears, this is an architecture with an impressive membership list.
