What it does

Transaction Models is an agent skill from Nethereum/Nethereum. Work with Ethereum transaction types and models in Nethereum. Use when the user needs to create, decode, or inspect transactions (legacy, EIP-1559, EIP-2930, EIP-7702), work with Chain IDs, block headers, access lists, transaction recovery, or TransactionFactory.

Its SKILL.md is about 1.1k 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 Ethereum. The repository describes itself as: Ethereum .Net cross platform integration library. The licence is MIT.

When your agent uses it

The user needs to create
Inspect transactions (legacy
Work with Chain IDs
Transaction recovery

Example prompts

“/transaction-models”

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
No scripts in the folder and no shell commands in SKILL.md (its code samples are csharp).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
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

Transaction Models loads about 1.1k tokens when it runs. Until then it costs about 71 tokens; SKILL.md has 82 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~71
When it runs · the whole SKILL.md, loaded when a task matches: ~1.1k

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.

Legacy Transaction

csharp

using System.Numerics;
using Nethereum.Model;
using Nethereum.Hex.HexConvertors.Extensions;
using Nethereum.RLP;

var to = "0x13978aee95f38490e9769C39B2773Ed763d9cd5F";
var amount = BigInteger.Parse("10000000000000000"); // 0.01 ETH
var nonce = BigInteger.Zero;
var gasPrice = BigInteger.Parse("1000000000000");
var gasLimit = BigInteger.Parse("10000");

var tx = new LegacyTransaction(to, amount, nonce, gasPrice, gasLimit);
// tx.TransactionType == TransactionType.LegacyTransaction

EIP-1559 Transaction

csharp

var tx = new Transaction1559(
    chainId, nonce, maxPriorityFeePerGas, maxFeePerGas,
    gasLimit, receiverAddress, amount, data, accessList: null);
// tx.TransactionType == TransactionType.EIP1559

EIP-2930 Access List Transaction

csharp

using System.Collections.Generic;

var storageKey = new byte[32];
storageKey[31] = 0x01;
var accessList = new List<AccessListItem>
{
    new AccessListItem(contractAddress, new List<byte[]> { storageKey })
};

var tx = new Transaction2930(chainId, nonce, gasPrice, gasLimit,
    receiverAddress, amount, null, accessList);
// tx.TransactionType == TransactionType.LegacyEIP2930
// Uses gasPrice (like legacy) + access list + chainId

EIP-7702 Authorization Transaction

csharp

using Nethereum.Signer;

// 1. Create and sign authorization
var authorisation = new Authorisation7702(chainId, contractAddress, nonce);
var authSigner = new Authorisation7702Signer();
var signedAuth = authSigner.SignAuthorisation(ecKey, authorisation);

// 2. Create transaction with authorization list
var tx = new Transaction7702(
    chainId, nonce, maxPriorityFeePerGas, maxFeePerGas,
    gasLimit, receiverAddress, amount, null,
    new List<AccessListItem>(), new List<Authorisation7702Signed> { signedAuth });
// tx.TransactionType == TransactionType.EIP7702
// Uses EIP-1559 fee model + authorization list

Transaction Recovery

csharp

using Nethereum.Signer;

// Recover sender address from signed transaction RLP
var sender = TransactionVerificationAndRecovery.GetSenderAddress(signedRlpHex);

// Verify a signed transaction is valid
var isValid = TransactionVerificationAndRecovery.VerifyTransaction(signedRlpHex);

// Works with all tx types: Legacy, EIP-1559, EIP-2930, EIP-7702

Decode Transaction from RLP

csharp

var rlpBytes = rlpHex.HexToByteArray();
var tx = new LegacyTransaction(rlpBytes);
// tx.Nonce, tx.GasPrice, tx.Value, tx.ReceiveAddress, tx.Signature

TransactionFactory (Auto-Detection)

csharp

var decoded = TransactionFactory.CreateTransaction(signedRlpHex);
// Type prefix: 0x01=EIP-2930, 0x02=EIP-1559, 0x05=EIP-7702, none=Legacy

What are the alternatives to Transaction Models?

Skills that share tags, products or a category with Transaction Models: NEAR Intents Swap Integration (internet-court/internet-court-skill, 6.4k stars), Explorer Contract Verification (sablier-labs/evm-monorepo, 353 stars), Developing Smart Contracts (LFDT-Lineth/lineth-monorepo, 126 stars) and Deposit Qr (Superior-Trade/superior-skills, 214 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.

Who maintains Transaction Models?

Nethereum (a GitHub organization) maintains it in Nethereum/Nethereum, which has 2,260 GitHub stars. The repository holds 71 skills in this directory. The repository was last updated on October 5, 2026.
