# Deposit

To trade with all of the exchange's features and be able to place passive orders into the books, the user must deposit funds to the Akira [exchange contract](/layerakira-documentation/integration/trading.md)

Deposit semantics:

* The user grants permission to the LayerAkira Smart Contract to move user' funds tokens via erc20 method **transferFrom** 
* The user will then execute an on chain deposit into the Smart Contract
* By monitoring on-chain events, the Exchange obtains the user's deposit and applies it to its internal state, allowing the user to trade on the Exchange with the amount deposited
