# depositConduit

Deposits assets into a conduit. Requires a `WalletClient` to sign and send the transaction.

:::info
This action automatically checks the ERC-20 allowance of the deposit token. If the current allowance is insufficient, it will send an **approval transaction** before the deposit, resulting in two transactions total.
