How CME resolves to CME

Each CME on-chain represents a 1:1 claim on the underlying CME Group Inc. held at an institutional custodian. The issuer and backing model are the same for every Flo token; only the underlying differs.

    Flo Finance issues CME as a tokenized CME Group Inc., 1:1 backed by the real underlying.

  2. 02

    Custody

    The underlying CME Group Inc. is held at Flo Finance, an institutional custodian.

  3. 03

    Settlement

    CME settles on-chain on Base, Arbitrum, Ethereum. Cross-chain transfers route through Chainlink CCIP.

  4. 04

    Attestation

    Reserves are attested daily by an independent auditor and published on the Flo transparency surface.

Where CME lives today

Flo distributes through partners. The same CME on-chain is the asset every partner integrates against; partner UIs may relabel it for their own brand.

Partner integrations in build

No live partner is distributing CME yet. Twelve integrations are in build across exchanges, wallets, fintechs, neobanks, and asset managers. Partners are listed here only after they ship.

Audits

Four independent firms, $250K bug bounty

Sherlock, Halborn, Cantina, and Cyfrin have audited the smart contracts that issue and settle CME. The same contracts power every Flo-issued token; one audit covers the catalogue.
