Tokenize MAIN via API
Main Street Capital 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 MAIN
Three primitives, one API key. MAINflows through the same path as the rest of Flo's tokenized equities universe.

Mint tokenized MAIN in one call
The same shape works for every ticker in the universe, swap the symbol and you're done.
// Mint tokenized MAIN (Main Street Capital) — notional-in default
const mint = await flo.mint({
asset: "MAIN",
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).
// MAIN ERC-20 tokens land via settle(order_id) once the broker leg confirms.
// Flo Capital SPC holds the underlying Main Street Capital shares at the broker-dealer, 1:1.Comparable assets via Flo

MAIN on Flo, common questions
Can I tokenize MAIN via Flo?
Yes. MAIN (Main Street Capital) is part of Flo's tokenized equities universe. A POST to /v1/mint with asset=MAIN and a notional_usdc amount returns a tokenized MAIN ERC-20 1:1-backed by Main Street Capital shares held at a SEC-registered broker-dealer (IB + Alpaca).
How is tokenized MAIN backed?
Each onchain MAIN token is backed 1:1 by a Main Street Capital 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 MAIN?
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. NYSE settles T+1 in USD, so the broker leg for MAIN clears on that cycle.
Can I borrow stablecoins against MAIN?
Yes. Tokenized MAIN 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 MAIN deployed on?
Tokenized MAIN 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.
