At a glance

Interact with the Circles UBI protocol using Nethereum (.NET/C).

  • The user asks about Circles protocol
  • SKILL.md covers Query Balances, Hub Contract Interaction, Mint Personal CRC and Transaction History, plus 4 more sections
  • Calls dotnet; reaches rpc.aboutcircles.com and chiado-rpc.aboutcircles.com
  • Universal Basic Income

What it does

Circles is an agent skill from Nethereum/Nethereum. Interact with the Circles UBI protocol using Nethereum (.NET/C). Use this skill whenever the user asks about Circles protocol, Universal Basic Income, CRC tokens, Circles balances, trust relationships, personal minting, demurrage tokens, or any Circles UBI interaction on Gnosis Chain with C or .NET.

Its SKILL.md is about 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 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 asks about Circles protocol
  • Universal Basic Income
  • Circles balances
  • Trust relationships

Example prompts

  • “/circles”

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

    Hosts in commands or code, which the agent is likely to contact:

    • rpc.aboutcircles.com
    • chiado-rpc.aboutcircles.com

    Also links to:

    • aboutcircles.com
    • 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

Circles loads about 1k tokens when it runs. Until then it costs about 78 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
~78
When it runs · the whole SKILL.md, loaded when a task matches
~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.

Circles: UBI Protocol

Circles is a decentralized Universal Basic Income protocol on Gnosis Chain. Every registered avatar receives 1 CRC per hour, with ~7% annual demurrage. Tokens transfer through trust networks — you can only send CRC to someone who trusts you. Nethereum's Nethereum.Circles package provides contract services for on-chain operations and custom RPC methods for data queries.

NuGet: Nethereum.Circles

bash
dotnet add package Nethereum.Circles

Query Balances

The Circles RPC endpoint exposes custom methods. The simplest balance check:

csharp
var client = new RpcClient(new Uri("https://rpc.aboutcircles.com/"));
var getTotalBalance = new GetTotalBalanceV2(client);
string balance = await getTotalBalance.SendRequestAsync("0xAvatarAddress");

This returns the total balance across all Circles token types — personal CRC plus any group currencies.

Hub Contract Interaction

The Hub is the central contract for avatar registration, trust, and minting:

csharp
var hubService = new HubService(web3, "0xc12C1E50ABB450d6205Ea2C3Fa861b3B834d13e8");

bool isHuman = await hubService.IsHumanQueryAsync("0xAddress");
bool isTrusted = await hubService.IsTrustedQueryAsync("0xTruster", "0xTrustee");
var issuance = await hubService.CalculateIssuanceQueryAsync("0xHumanAddress");

These are read-only calls — no gas needed.

Mint Personal CRC

Circles avatars typically use Gnosis Safe wallets. Mint through Safe execution using the ChangeContractHandlerToSafeExecTransaction extension from Nethereum.GnosisSafe:

csharp
var hubService = new HubService(web3, hubAddress);
hubService.ChangeContractHandlerToSafeExecTransaction(safeAddress, privateKey);
await hubService.PersonalMintRequestAndWaitForReceiptAsync();

The Safe is the registered avatar, not the EOA. The extension method wraps the mint call in a Safe execTransaction.

Transaction History

Paginated transaction history through the Circles RPC:

csharp
var historyQuery = new GetTransactionHistoryQuery(client);
var transactions = await historyQuery.SendRequestAsync("0xAvatarAddress", 100);

foreach (var tx in transactions.Response)
    Console.WriteLine($"{tx.From} → {tx.To}: {tx.Value}");

// Next page
var nextPage = await historyQuery.MoveNextPageAsync(transactions);

Trust Relationships

Query who trusts whom:

csharp
var trustQuery = new GetTrustRelationsQuery(client);
var relations = await trustQuery.SendRequestAsync("0xAvatarAddress", 20);

foreach (var r in relations.Response)
    Console.WriteLine($"Truster: {r.Truster} → Trustee: {r.Trustee}");

Trust is directional — if A trusts B, B can send personal CRC to A.

Get Avatar Info

Query metadata about a Circles avatar:

csharp
var avatarInfo = new GetAvatarInfoQuery(client);
var info = await avatarInfo.SendRequestAsync("0xAvatarAddress");

This returns the avatar's name, type (human, organization, group), and associated token information.

Can I use Circles in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add Nethereum/Nethereum --skill circles -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/circles, .gemini/skills/circles, .github/skills/circles and .opencode/skills/circles in your project.

What does Circles need to run?

Going by SKILL.md and its folder, Circles needs the command-line tools its instructions call (dotnet).

Does Circles access the network?

SKILL.md names 4 domains. In commands or code: rpc.aboutcircles.com and chiado-rpc.aboutcircles.com; the agent is likely to contact these when it follows the instructions. As links in the text: aboutcircles.com and docs.nethereum.com. This is read from the text; nothing was executed.
