A reference of all operations available on credit accounts. Each operation can be included as a call within a multicall.

## SDK Helpers vs Manual Encoding

**Five operations have SDK helpers** via `createCreditAccountService`:

* `prepareAddCollateral(token, amount)`
* `prepareIncreaseDebt(amount)`
* `prepareDecreaseDebt(amount)`
* `prepareUpdateQuota(token, change, minQuota)`
* `prepareWithdrawCollateral(token, amount, to)`

**Six operations require manual encoding** with viem's `encodeFunctionData`:

* `storeExpectedBalances` / `compareBalances`
* `enableToken` / `disableToken`
* `onDemandPriceUpdate`
* `setFullCheckParams`
* `revokeAdapterAllowances`

All manual encoding uses `iCreditFacadeV300MulticallAbi` from `@gearbox-protocol/sdk`.
