**Why mint redemption?**
\
Large / unpredictable redemptions. Mint path avoids liquidity crunches for fund manager.
**Why transfer redemption?**
\
Small / frequent redemptions. P2P transfer path works if reserve buffer sized correctly.

### BUIDL & USDC
***INSTANT MINT SUBSCRIPTION***
**Step 1: Atomic Mint Transaction**
\
(1) The user interacts with the InstantManager smart contract to request a subscription.
\
(2) The InstantManager contract immediately routes the investor’s USDC to the USDXT Coinbase Account of XFT.
\
(3) The InstantManager contract calls the Price Oracle contract to
\
(4) get the current price of USDXT.
\
(5) The instantManager contract uses that price to calculate how many USDXT to mint.
\
(6) The InstantManager contract then calls the mint() function in the USDXT smart contract, which
\
(7) mints the correct number of USDXT tokens.
\
(8) The InstantManager contract then routes these newly minted USDXT tokens to the investor.
**Step 2: Manual Processing**
\
(1) Operations team converts USDC to USD
\
(2) Team wires USD to Fund's custodial account
\
(3) Team places buy order for BUIDL tokens
\
(4) Team wires money from custodian to fill BUIDL order
\
(5) BUIDL tokens are minted and sent to USDXT's smart contract for storage
***INSTANT REDEMPTION***
(1) The investor initiates the redemption to the USDXTInstantManager smart contract.
\
(2) The InstantManager contract calls the transferFrom() function of the USDXT Token contract, which causes
\
(3) the USDXT to be transferred from the investor’s wallet into the InstantManager contract, which then
\
(4) burns the USDXT. To figure out how much USDC is due to the investor (and therefore how many BUIDL are necessary to sell), the InstantManager contract
\
(5) calls the getPriceData() function in the USDXT Price Oracle, which
\
(6) returns the price. Once the InstantManager contract
\
(7) determines how many BUIDL must be sold, it
\
(8) initiates the redeem() function in the Circle BUIDL redemption contract, which then
\
(9) returns USDC. Finally, (10), the InstantManager sends the USDC to the investor’s wallet.
Non-instant mint and redemption occurs in a similar way, but with more manual steps and non-atomically.
