# INFERENCE

> Buy INFERENCE, activate it as service credit, or trade it through the available markets.

INFERENCE is an ERC-20 on Ethereum. Buy it and turn it into [service credit](https://deference.si/docs/concepts/credit-and-activation) when you want to spend it on model requests.

## Buy INFERENCE

Open [Buy INFERENCE](https://deference.si/overview?action=buy) on Home and choose USDC or ETH to pay with. USDC is the default. The quote compares the available sale and order book routes. Check the output, fees, and minimum received before confirming.

The sale sends the purchase fee to the treasury and the remaining USDC to its funding wallet. [Stats](https://deference.si/stats) shows the wallet's observed USDC balance and INFERENCE supply, with the block used for the read.

To buy and activate in one transaction, open [Add credit](https://deference.si/overview) and pay with USDC. Add credit also accepts INFERENCE already in your wallet.

Credit cannot be turned back into INFERENCE, so activate what you plan to spend.
