 ### `estimateFees` function
 
 ```ts
-estimateFees(params: EstimateFeeParams): Promise<bigint>
+estimateFees(options: OracleTransactionParameters<TAbi, TFunctionName> & GasPriceOracleOptions & Omit<EstimateGasParameters, 'data'>): Promise<bigint>
 ```
 
 #### Parameters
 
-`params`: An object with the following fields:
-
-- `client`: An object with `rpcUrl` and `chainId` fields, or an instance of a Viem `PublicClient`.
+`options`: An object with the following fields:
 
-- `blockNumber`: A BigInt representing the block number at which you want to estimate the fees.
+- abi: A JSON object ABI of contract.
 
-- `blockTag`: A string representing the block tag to query from.
+- account: A hex address of the account making the transaction.
 
-- `account`: A string representing the account making the transaction.
+- args: Array of arguments to contract function. The types of this will be inferred from the ABI
 
-- `to`: A string representing the recipient of the transaction.
+- blockNumber(optional): A BigInt representing the block number at which you want to estimate the fees.
 
-- `data`: A string representing the data being sent with the transaction. This should be a 0x-prefixed hex string.
+- chainId: An integer chain id.
 
-#### Returns
+- client: An object with rpcUrl field, or an instance of a Viem PublicClient.
 
-A Promise that resolves to a BigInt representing the estimated fee in wei.
+- functionName: A string representing the function name for the transaction call data.
 
-## FAQ
+- maxFeePerGas(optional): A BigInt representing the maximum fee per gas that the user is willing to pay.
 
-### How to encode function data?
+- maxPriorityFeePerGas(optional): A BigInt representing the maximum priority fee per gas that the user is willing to pay.
 
-You can use our package to encode the function data. Here is an example:
+- to: A hex address of the recipient of the transaction.
 
-```ts
-import { encodeFunctionData } from '@eth-optimism/fee-estimation'
-import { optimistABI } from '@eth-optimism/contracts-ts'
+- value(optional): A BigInt representing the value in wei sent along with the transaction.
 
-const data = encodeFunctionData({
-  functionName: 'burn',
-  abi: optimistABI,
-  args: [BigInt('0x77194aa25a06f932c10c0f25090f3046af2c85a6')],
-})
-```
-
-This will return a 0x-prefixed hex string that represents the encoded function data.
-
-## Testing
+#### Returns
 
-The package provides a set of tests that you can run to verify its operation. The tests are a great resource for examples. You can find them at `./src/estimateFees.spec.ts`.
+A Promise that resolves to a BigInt representing the estimated fee in wei.
