gnosis-safeExecute multi-signature transactions through Gnosis Safe (Safe) using Nethereum (.NET/C).
Gnosis Safe is an agent skill from Nethereum/Nethereum. Execute multi-signature transactions through Gnosis Safe (Safe) using Nethereum (.NET/C). Use this skill whenever the user asks about multi-sig wallets, Gnosis Safe, Safe transactions, SafeAccount, multi-signature signing, MultiSend, or executing contract calls through a Safe with C or .NET.
Its SKILL.md is about 1.6k 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.
Read from SKILL.md and the folder at commit 229f278. It shows what the files ask for, not the result of running them.
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.
Shell commands in SKILL.md call:

Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Gnosis Safe loads about 1.6k tokens when it runs. Until then it costs about 77 tokens; SKILL.md has 358 words of instructions outside code blocks.
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.
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.

.claude/skills/gnosis-safe/SKILL.md (or your agent's skills folder).Gnosis Safe (now "Safe") is the most widely used multi-signature wallet on Ethereum. Nethereum's Nethereum.GnosisSafe package provides three levels of integration: SafeAccount (transparent — any contract service auto-routes through Safe), ChangeContractHandlerToSafeExecTransaction (per-service switching), and manual transaction building with EIP-712 signatures.
NuGet: Nethereum.GnosisSafe
dotnet add package Nethereum.GnosisSafeThe simplest approach — create a SafeAccount and every contract service created from that web3 instance automatically executes through the Safe:
var safeAccount = new SafeAccount(safeAddress, chainId, privateKey);
var web3 = new Web3(safeAccount, rpcUrl);
// This ERC-20 transfer executes through the Safe
var erc20 = new ERC20ContractService(web3.Eth, tokenAddress);
var receipt = await erc20.TransferRequestAndWaitForReceiptAsync(to, amount);SafeAccount implements IContractServiceConfigurableAccount, which swaps the contract handler to SafeExecTransactionContractHandler. The call data gets packed into a Safe execTransaction, signed with EIP-712, and submitted.
Switch a specific contract service to Safe execution without changing the entire web3:
var erc20 = new ERC20ContractService(web3.Eth, contractAddress);
erc20.ChangeContractHandlerToSafeExecTransaction(safeAddress, privateKey);
// Only this service goes through Safe; others execute directlyThis is useful when some operations should go through the Safe and others shouldn't.
For full control or multi-owner signature collection:
var safeService = new GnosisSafeService(web3, safeAddress);
var transactionData = new EncodeTransactionDataFunction
{
To = targetAddress,
Value = 0,
Data = encodedCallData,
Operation = 0, // 0 = Call, 1 = DelegateCall
SafeTxGas = 0,
BaseGas = 0,
SafeGasPrice = 0,
GasToken = AddressUtil.ZERO_ADDRESS,
RefundReceiver = AddressUtil.ZERO_ADDRESS
};
var execTx = await safeService.BuildTransactionAsync(
transactionData, chainId, false, privateKey1, privateKey2);
var receipt = await safeService.ExecTransactionRequestAndWaitForReceiptAsync(execTx);BuildTransactionAsync fetches the nonce, hashes the data with EIP-712, signs with each key, orders signatures by signer address (required by Safe), and returns a ready-to-submit function.
When owners can't sign in the same session, compute the hash and collect signatures separately:
// Compute hash
transactionData.SafeNonce = await safeService.NonceQueryAsync();
var safeHashes = GnosisSafeService.GetSafeHashes(transactionData, chainId, safeAddress);
// Each owner signs independently
var signature = await safeService.SignEncodedTransactionDataAsync(
transactionData, chainId, convertToSafeVFormat: true);Safe uses a custom V format (V+4 from standard Ethereum). The convertToSafeVFormat: true parameter handles this automatically.
var signatures = new List<SafeSignature>
{
new SafeSignature { Address = owner1Address, Signature = signature1 },
new SafeSignature { Address = owner2Address, Signature = signature2 }
};
var combinedSignatures = safeService.GetCombinedSignaturesInOrder(signatures);Safe requires signatures ordered by signer address (ascending). GetCombinedSignaturesInOrder handles sorting and concatenation.
Batch multiple actions in a single Safe transaction using typed MultiSendFunctionInput<T>:
var input1 = new MultiSendFunctionInput<TransferFunction>(
new TransferFunction { To = recipient1, Value = amount1 }, tokenAddress);
var input2 = new MultiSendFunctionInput<TransferFunction>(
new TransferFunction { To = recipient2, Value = amount2 }, tokenAddress);
var execTx = await safeService.BuildMultiSendTransactionAsync(
transactionData, chainId, privateKey, false, input1, input2);
var receipt = await safeService.ExecTransactionRequestAndWaitForReceiptAsync(execTx);MultiSendFunctionInput<T> implements IMultiSendInput and encodes call data automatically. BuildMultiSendTransactionAsync sets Operation to DelegateCall (required by MultiSend).
var owners = await safeService.GetOwnersQueryAsync();
var threshold = await safeService.GetThresholdQueryAsync();
var nonce = await safeService.NonceQueryAsync();
var version = await safeService.VersionQueryAsync();
var isOwner = await safeService.IsOwnerQueryAsync(address);
Console.WriteLine($"Safe v{version}: {owners.Count} owners, threshold {threshold}, nonce {nonce}");| Parameter | Purpose |
|---|---|
SafeTxGas | Gas for the internal Safe transaction. Set 0 to let the Safe estimate. |
BaseGas | Gas overhead independent of execution. Usually 0. |
SafeGasPrice | Gas price for refund calculation. Set 0 for no refund. |
GasToken | Token to pay gas refunds in. address(0) = ETH. |
RefundReceiver | Address receiving the gas refund. address(0) = tx.origin. |
For most use cases, setting all gas parameters to 0 is correct — the Safe uses Ethereum's standard gas mechanism.
| Approach | When |
|---|---|
SafeAccount | All contract calls should go through Safe — simplest |
ChangeContractHandlerToSafeExecTransaction | Only specific services should use Safe |
Manual BuildTransactionAsync | Need multi-owner signature collection or custom gas params |
BuildMultiSendTransactionAsync | Batch multiple actions in one Safe tx |

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add Nethereum/Nethereum --skill gnosis-safe -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/gnosis-safe, .gemini/skills/gnosis-safe, .github/skills/gnosis-safe and .opencode/skills/gnosis-safe in your project.
Going by SKILL.md and its folder, Gnosis Safe needs the command-line tools its instructions call (dotnet).
SKILL.md names 1 domain. As links in the text: docs.nethereum.com. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Gnosis Safe is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.6k tokens (SKILL.md is roughly 6.2k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
