Tokenize COST via API
Costco Wholesale as a 1:1-backed onchain ERC-20. Mint, redeem, and post as collateral with one SDK call. Mint and redeem are asynchronous via an on-chain order_id; the terminal action lands via settle(order_id) on the broker-dealer cycle (T+1).
What Flo supports for COST
Three primitives, one API key. COSTflows through the same path as the rest of Flo's tokenized equities universe.
Mint COST →
Create tokenized COST from stablecoin payment. Onchain delivery is instant; the broker buys the underlying Costco Wholesale share at NASDAQ during market hours.
Redeem COST →
Burn tokenized COST and receive stablecoin. Flo Capital SPC sells the underlying Costco Wholesale share at the broker-dealer; your user gets stablecoin instantly.
Borrow against COST →
Post tokenized COST as collateral and borrow USDC/USDT up to 70% LTV. Liquidations route through the same broker pipe.
Mint tokenized COST in one call
The same shape works for every ticker in the universe, swap the symbol and you're done.
// Mint tokenized COST (Costco Wholesale) — notional-in default
const mint = await flo.mint({
asset: "COST",
notional_usdc: "1000.00", // pay-in. SDK derives min_quantity from quote * (1 + slippage_bps).
slippage_bps: 50, // 0.50%. Default if omitted.
settlement: {
currency: "USDC", // per-chain accepted set in /v1/chains
chain: 8453, // Base. EIP-155 integer chain ID.
wallet: userWalletAddress,
},
gas: { sponsor: "developer" },
});
// mint.status is "active" with mint.order_id set on chain (or "queued" out-of-session).
// COST ERC-20 tokens land via settle(order_id) once the broker leg confirms.
// Flo Capital SPC holds the underlying Costco Wholesale shares at the broker-dealer, 1:1.Comparable assets via Flo

COST on Flo, common questions
Can I tokenize COST via Flo?
Yes. COST (Costco Wholesale) is part of Flo's tokenized equities universe. A POST to /v1/mint with asset=COST and a notional_usdc amount returns a tokenized COST ERC-20 1:1-backed by Costco Wholesale shares held at a SEC-registered broker-dealer (IB + Alpaca).
How is tokenized COST backed?
Each onchain COST token is backed 1:1 by a Costco Wholesale 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 COST?
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 COST clears on that cycle.
Can I borrow stablecoins against COST?
Yes. Tokenized COST 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 COST deployed on?
Tokenized COST 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.
