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.
