GBDC on Flo, common questions
Can I tokenize GBDC via Flo?
Yes. GBDC (Golub Capital BDC) is part of Flo's tokenized equities universe. A POST to /v1/mint with asset=GBDC and a notional_usdc amount returns a tokenized GBDC ERC-20 1:1 backed by Golub Capital BDC shares held at an institutional custodian by Flo Finance.
How is tokenized GBDC backed?
Each onchain GBDC token is 1:1 backed by a real Golub Capital BDC share held at institutional custodians by Flo Finance. Reserves are attested daily and published on /transparency/proof-of-reserves.
What is the settlement window for GBDC?
Mint and redeem are asynchronous via an on-chain order_id. The create-order tx is atomic; the terminal action (live token mint or stablecoin payout) lands via settle(order_id) on the custodian cycle. NASDAQ settles T+1 in USD, so the custodian leg for GBDC clears on that cycle.

APR is a floating rate set by the pool's utilization curve (kinks at 75% and 90%). See /docs#borrow-overview for the full state machine.
