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 a SEC-registered broker-dealer (IB + Alpaca).
How is tokenized GBDC backed?
Each onchain GBDC token is backed 1:1 by a Golub Capital BDC share held by Flo Capital SPC (Cayman), a bankruptcy-remote Segregated Portfolio Company, in segregated brokerage accounts at Flo's SEC-registered broker-dealers. 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 broker-dealer cycle. NASDAQ settles T+1 in USD, so the broker leg for GBDC clears on that cycle.
Can I borrow stablecoins against GBDC?
Yes. Tokenized GBDC is collateral-eligible in the Flo borrow product as a large-cap equity, with a three-margin model — initial 70% (max LTV at open), maintenance 75% (alerts begin via borrow.maintenance_breach), liquidation 78% (keepers auto-close on a 30-second TWAP, no grace window). 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.
Which chains is GBDC deployed on?
Tokenized GBDC is deployable on Base, Arbitrum, Ethereum. Pass the EIP-155 integer chain ID on the settlement object (8453 for Base, 42161 for Arbitrum, 1 for Ethereum). String slugs are not accepted on input; see /docs#rest-chains.
