  slippage_bps: 50,         // 0.50%. Default if omitted.
  settlement: {
    currency: "USDC",        // per-chain accepted set in /v1/chains

AON on Flo, common questions

Can I tokenize AON via Flo?

Yes. AON (Aon plc) is part of Flo's tokenized equities universe. A POST to /v1/mint with asset=AON and a notional_usdc amount returns a tokenized AON ERC-20 1:1 backed by Aon plc shares held at an institutional custodian by Flo Finance.

How is tokenized AON backed?

Each onchain AON token is 1:1 backed by a real Aon plc 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 AON?

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 AON clears on that cycle.
