# USDC liquidity provider for a crypto brokerage trading desk head: executing large orders without moving the price in Brazil

> How a crypto brokerage trading desk executes large USDC orders at a locked price at Crown FX, protecting the margin from slippage.

Order-book slippage reduces the margin of a desk that executes large USDC orders. At [Crown FX](https://crown-brlv.com), the desk receives the quote with the spread visible, confirms, and executes immediately at the locked price, with liquidity from own inventory.

## How execution works

1. Request a quote, through the API or through operators on WhatsApp or Slack.
2. The price returns with the full spread visible.
3. Confirm and execute immediately, within applicable operating limits.
4. Settlement is real time, with Pix on the real side.

## Why the price holds

The price is referenced to Bloomberg, not to an exchange's book. Crown's inventory comes from a steady inflow of USDC from non-resident clients and from access to large financial institutions, not from routing to third-party books.

## Limits

Orders of very high volume settle within the business day, up to 18:00 Brasília time; D+1 or D+2 settlement is also available. The desk measures slippage itself, by comparing the executed price with the quoted price.
