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 custodian leg confirms.
// Flo Finance holds the underlying Costco Wholesale shares at an institutional custodian, 1:1.

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 an institutional custodian by Flo Finance.

How is tokenized COST backed?

Each onchain COST token is 1:1 backed by a real Costco Wholesale 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 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 custodian cycle. NASDAQ settles T+1 in USD, so the custodian 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.
