What it does

Aa Bundler is an agent skill from Nethereum/Nethereum. Help users run an ERC-4337 bundler using Nethereum — set up in-process or standalone bundlers with mempool, validation, reputation, and JSON-RPC server. Use when the user mentions running a bundler, ERC-4337 bundler setup, BundlerService, BundlerConfig, bundler RPC server, mempool configuration, UserOperation validation, or bundler presets (AppChain, Standard, Production) in .NET/C.

Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Backend & APIs. It works with C# and .NET. The repository describes itself as: Ethereum .Net cross platform integration library. The licence is MIT.

When your agent uses it

Example prompts

“/aa-bundler”

What it can do on your machine

Read from SKILL.md and the folder at commit 229f278. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
- dotnet
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
- docs.nethereum.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Aa Bundler loads about 1.2k tokens when it runs. Until then it costs about 99 tokens; SKILL.md has 250 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~99
When it runs · the whole SKILL.md, loaded when a task matches: ~1.2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

user-invocable: true

Run an ERC-4337 Bundler

Nethereum includes a full ERC-4337 bundler — collects UserOperations, validates them, manages a mempool with reputation tracking, and submits bundles to the EntryPoint.

When to Use This

User wants to run their own bundler instead of using a third-party service
User is building an application chain that needs an integrated bundler
User needs to configure bundler settings (validation, mempool, reputation)
User wants a JSON-RPC endpoint for the bundler

Packages

bash

dotnet add package Nethereum.AccountAbstraction.Bundler
dotnet add package Nethereum.AccountAbstraction.Bundler.RpcServer  # for JSON-RPC endpoint

Quick Start

csharp

using Nethereum.AccountAbstraction.Bundler;
using Nethereum.Web3;
using Nethereum.Web3.Accounts;

var web3 = new Web3(new Account(privateKey), "http://localhost:8545");

var config = BundlerConfig.CreateAppChainConfig(
    entryPoint: EntryPointAddresses.Latest,
    beneficiary: "0xBeneficiaryAddress");

var bundlerService = new BundlerService(web3, config);

// Submit a UserOperation
string userOpHash = await bundlerService.SendUserOperationAsync(
    packedUserOp, EntryPointAddresses.Latest);

// Trigger immediate bundling
BundleResult result = await bundlerService.ExecuteBundleAsync();

// Check receipt
var receipt = await bundlerService.GetUserOperationReceiptAsync(userOpHash);

Configuration Presets

Preset	Use Case	StrictValidation	ERC-7562	AutoBundle
`CreateAppChainConfig`	Private chains	false	false	1s
`CreateStandardConfig`	Public testnets	true	true	10s
`CreateProductionConfig`	Mainnet	true	true	10s + staking

csharp

var appConfig = BundlerConfig.CreateAppChainConfig(entryPoint, beneficiary);
var stdConfig = BundlerConfig.CreateStandardConfig(entryPoint, beneficiary);
var prodConfig = BundlerConfig.CreateProductionConfig(entryPoint, beneficiary);

Key Config Properties

Property	Default	Description
`MaxBundleSize`	10	Max UserOperations per bundle
`MaxMempoolSize`	1000	Max UserOperations in mempool
`AutoBundleIntervalMs`	10000	Bundle interval (0 = manual)
`StrictValidation`	true	Enforce ERC-4337 rules
`EnableERC7562Validation`	false	Trace-based opcode validation
`UnsafeMode`	false	Skip all validation (testing only)
`MinStake`	1 ETH	Min stake for reputation
`WhitelistedAddresses`	empty	Exempt from reputation checks
`BlacklistedAddresses`	empty	Permanently rejected

JSON-RPC Server

csharp

using Nethereum.AccountAbstraction.Bundler.RpcServer;

var rpcServer = new RpcServer();
rpcServer.AddBundlerHandlers(bundlerService);

// Or create bundler from config:
rpcServer.AddBundlerHandlers(web3, config);

Standard RPC Methods

Method	Description
`eth_sendUserOperation`	Submit UserOperation
`eth_estimateUserOperationGas`	Estimate gas
`eth_getUserOperationByHash`	Look up by hash
`eth_getUserOperationReceipt`	Get receipt
`eth_supportedEntryPoints`	List EntryPoints
`eth_chainId`	Return chain ID

Debug Methods

Method	Description
`debug_bundler_sendBundleNow`	Force immediate bundle
`debug_bundler_dumpMempool`	Dump mempool contents
`debug_bundler_dumpReputation`	Dump reputation scores
`debug_bundler_setReputation`	Set reputation manually

Reputation and Staking

csharp

var config = BundlerConfig.CreateProductionConfig(entryPoint, beneficiary);
config.WhitelistedAddresses.Add("0xYourPaymaster");  // trust your paymaster
config.BlacklistedAddresses.Add("0xBadFactory");      // block bad actors

Common Mistakes

No beneficiary — required, receives bundler fees
Wrong EntryPoint — bundler only accepts ops targeting SupportedEntryPoints
AutoBundle=0 without manual bundling — ops pile up, never submitted
UnsafeMode in production — skips all validation, wastes gas on bad ops
