# pm\_getPaymasterStubData `pm_getPaymasterStubData` is the ERC-7677 paymaster JSON-RPC method that returns placeholder paymaster fields, so a user operation can be gas-estimated before its final paymaster data is requested. This method returns stub values to be used in paymaster-related fields of an unsigned user operation for gas estimation. The context parameter can be an object with either a `token` field (for ERC-20 mode) or a `sponsorshipPolicyId` field (for sponsorship mode), or null. ## EntryPoint 0.7 & 0.8 :::tip The context parameter can be one of the following: * An object with a `token` field containing the ERC-20 token address for token payments * An object with a `sponsorshipPolicyId` field for sponsored transactions * `null` for other cases ::: ### Usage ```json { "jsonrpc": "2.0", "method": "pm_getPaymasterStubData", "params": [ { "sender": "0x5a6b47F4131bf1feAFA56A05573314BcF44C9149", "nonce": "0x845ADB2C711129D4F3966735ED98A9F09FC4CE5700000000000000000000", "factory": "0xd703aaE79538628d27099B8c4f621bE4CCd142d5", "factoryData": "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", "callData": "0xe9ae5c53", "callGasLimit": "0x13880", "verificationGasLimit": "0x60B01", "preVerificationGas": "0xD3E3", "maxPriorityFeePerGas": "0x3B9ACA00", "maxFeePerGas": "0x7A5CF70D5", "paymaster": null, "paymasterVerificationGasLimit": null, "paymasterPostOpGasLimit": null, "paymasterData": null, "eip7702Auth": { "address": "0x1234567890123456789012345678901234567890", "chainId": "0x1", "nonce": "0x1", "r": "0x1234567890123456789012345678901234567890123456789012345678901234", "s": "0x1234567890123456789012345678901234567890123456789012345678901234", "v": "0x1b", "yParity": "0x1" } }, "0x0000000071727De22E5E9d8BAf0edAc6f37da032", "0x1", { "token": "0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48" // Or alternatively: "sponsorshipPolicyId": "policy-123456" } ], "id": 4337 } ``` ### Parameters The method accepts an array with the following parameters: 1. **userOperation** - `Object`: The user operation object containing the following fields: * **sender** - `Address`: The account making the operation. * **nonce** - `HexString`: Unique identifier for the request from this sender. * **factory** - `Address (optional)`: The factory contract address. * **factoryData** - `HexData (optional)`: The factory data for account creation. * **callData** - `HexData`: The data to pass to the sender during the main execution call. * **callGasLimit** - `HexNumber`: The amount of gas to allocate the main execution call. * **verificationGasLimit** - `HexNumber`: The amount of gas to allocate for the verification step. * **preVerificationGas** - `HexNumber`: The amount of gas to pay for to compensate the bundler for pre-verification execution and calldata. * **maxFeePerGas** - `HexNumber`: Maximum fee per gas (similar to EIP-1559 max\_fee\_per\_gas). * **maxPriorityFeePerGas** - `HexNumber`: Maximum priority fee per gas (similar to EIP-1559 max\_priority\_fee\_per\_gas). * **paymaster** - `Address (optional)`: Address of paymaster sponsoring the transaction, or null if none. * **paymasterVerificationGasLimit** - `HexNumber (optional)`: The amount of gas to allocate for the verification step of the paymaster, or null if no paymaster. * **paymasterPostOpGasLimit** - `HexNumber (optional)`: The amount of gas to allocate for the post-operation step of the paymaster, or null if no paymaster. * **paymasterData** - `HexData (optional)`: The data to pass to the paymaster during the verification step, or null if no paymaster. * **eip7702Auth** - `Object (optional)`: EIP-7702 authorization data, can be null.
