What it does

Smart Account Deployment is an agent skill from Nethereum/Nethereum. Help users deploy ERC-4337 smart accounts using Nethereum — create a modular NethereumAccount via IAAClient, predict counterfactual addresses with CREATE2, deploy lazily via InitCode on the first UserOperation, manage EntryPoint deposits. Use when the user mentions deploying a smart account, creating a smart wallet, CREATE2 account address, counterfactual address, NethereumAccountFactory, SimpleAccountFactory, or account factory deployment in .NET/C.

Its SKILL.md is about 1.5k 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 DevOps & Cloud, covering Deployment. 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

  • The user mentions deploying a smart account
  • Creating a smart wallet
  • CREATE2 account address
  • Counterfactual address

Example prompts

  • “/smart-account-deployment”

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

Smart Account Deployment loads about 1.5k tokens when it runs. Until then it costs about 120 tokens; SKILL.md has 257 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~120
When it runs · the whole SKILL.md, loaded when a task matches
~1.5k

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.

Smart Account Deployment

Deploy ERC-4337 smart accounts with Nethereum — predict addresses before deployment with CREATE2, deploy upfront or lazily via the first UserOperation's InitCode.

When to Use This

  • User wants to deploy a new smart contract wallet
  • User needs to predict an account address before deployment (CREATE2)
  • User wants lazy deployment — deploy the account as part of the first UserOperation
  • User is working with NethereumAccountFactory, SimpleAccountFactory, or a custom account factory

Packages

bash
dotnet add package Nethereum.Web3
dotnet add package Nethereum.AccountAbstraction
dotnet add package Nethereum.AccountAbstraction.SimpleAccount  # only for the SimpleAccount reference account

The instant on-ramp predicts the counterfactual address and returns a ready-to-use NethereumSmartAccount — no deploy transaction needed, the account deploys itself on its first UserOperation:

csharp
using Microsoft.Extensions.DependencyInjection;
using Nethereum.AccountAbstraction.Client;
using Nethereum.AccountAbstraction.Configuration;
using Nethereum.Signer;

services.AddNethereumAccountAbstraction(o => o
    .UseWeb3(web3)
    .UseDeploymentAddresses(new AADeploymentAddresses(
        EntryPointAddress: EntryPointAddresses.Latest,
        NethereumAccountFactoryAddress: factoryAddress,
        EcdsaValidatorAddress: ecdsaValidatorAddress,
        VerifyingPaymasterAddress: ""))
    .UseBundlerUrl(bundlerUrl));

var aaClient = serviceProvider.GetRequiredService<IAAClient>();

var owner = EthECKey.GenerateKey();
var account = await aaClient.CreateAccountAsync(owner, salt: null);  // random salt if omitted

Console.WriteLine($"Counterfactual address: {account.Address}");
Console.WriteLine($"Is deployed: {account.IsDeployed}");

// Fund it, then drive any generated typed service through it — the first call deploys it
await web3.Eth.GetEtherTransferService()
    .TransferEtherAndWaitForReceiptAsync(account.Address, 0.1m);

myTokenService.UseAccountAbstraction(account, aaClient);
var receipt = await myTokenService.TransferRequestAndWaitForReceiptAsync(recipient, amount);

Attach to an Already-Deployed Account

csharp
// Modular NethereumAccount, with its ERC-7579 validator
var account = aaClient.GetAccount(accountAddress, signingService, validator);

// Plain non-modular account (e.g. SimpleAccount) — no validator
var account = aaClient.GetAccount(accountAddress, signingService);

// Shortcut for an already-deployed NethereumAccount's generated service:
var accountService = new NethereumAccountService(web3, accountAddress);

Lower-Level: NethereumAccountFactoryService Directly

IAAClient.CreateAccountAsync is built on this factory — reach for it directly when you need the raw counterfactual address/init-code without going through the client:

csharp
using Nethereum.AccountAbstraction.Contracts.Core.NethereumAccountFactory;
using Nethereum.AccountAbstraction.ERC7579.Modules;

var factory = new NethereumAccountFactoryService(web3, factoryAddress);
var initData = AccountInitDataBuilder.BuildEcdsa(ecdsaValidatorAddress, ownerAddress);
var salt = new byte[32]; // fill with your own CREATE2 salt

// Predict address without deploying
var address = await factory.GetAddressQueryAsync(salt, initData);
var isDeployed = await factory.IsDeployedQueryAsync(salt, initData);
var initCode = await factory.GetInitCodeQueryAsync(salt, initData);

Lazy Deployment via InitCode

Nothing extra to do: IAAClient.Configure/ChangeContractHandlerToAA check on-chain whether the account exists and attach the factory's InitCode to the first UserOperation automatically. On subsequent calls it's omitted. See Nethereum.AccountAbstraction's README for the low-level FactoryConfig walkthrough (SimpleAccount-family accounts).

SimpleAccount (non-modular reference account)

csharp
using Nethereum.AccountAbstraction.SimpleAccount.SimpleAccountFactory;
using Nethereum.AccountAbstraction.SimpleAccount.SimpleAccountFactory.ContractDefinition;

var factory = await SimpleAccountFactoryService.DeployContractAndGetServiceAsync(
    web3, new SimpleAccountFactoryDeployment { EntryPoint = entryPointAddress });

var accountAddress = await factory.GetAddressQueryAsync(ownerKey.GetPublicAddress(), salt: 0);

EntryPoint Deposits (NethereumAccount)

csharp
var deposit = await accountService.GetDepositQueryAsync();
await accountService.AddDepositAsync(Web3.Convert.ToWei(0.1m));
await accountService.WithdrawDepositToRequestAndWaitForReceiptAsync(withdrawAddress, amount);

EntryPoint Versions

Use EntryPointAddresses.Latest (V09) for new deployments. The account is bound to the EntryPoint version at deploy time.

Common Mistakes

  • Not funding the counterfactual address before the first UserOperation
  • Changing the salt between prediction and deployment (produces a different address)
  • Wrong factory address between prediction and deployment
  • Wrong EntryPoint — account is bound to one version
  • Mismatched validator — GetAccount(address, signingService, validator) must use the same validator the account was created/installed with, or signature validation fails
