Tokenize MET via API
MetLife Inc. 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 custodian cycle (T+1).
What Flo supports for MET
Three primitives, one API key. METflows through the same path as the rest of Flo's tokenized equities universe.

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

MET on Flo, common questions
Can I tokenize MET via Flo?
Yes. MET (MetLife Inc.) is part of Flo's tokenized equities universe. A POST to /v1/mint with asset=MET and a notional_usdc amount returns a tokenized MET ERC-20 1:1 backed by MetLife Inc. shares held at an institutional custodian by Flo Finance.
How is tokenized MET backed?
Each onchain MET token is 1:1 backed by a real MetLife Inc. 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 MET?
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. NYSE settles T+1 in USD, so the custodian leg for MET clears on that cycle.
Can I borrow stablecoins against MET?
Yes. Tokenized MET 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 MET deployed on?
Tokenized MET 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.
