Quickstart Guide for Circles SDK

This guide will help you get started with the Circles SDK. It shows how to use the Circles SDK with MetaMask.

Prerequisites

• Browser wallet such as Metamask or Rabby Wallet

• Setup or add Gnosis Chain (Mainnet) as your network for wallet. Check out Gnosis Chain docs here.

• Some xDAI token for paying gas fees. Check out Mainnet Faucet

Circles SDK Installation

If you have all prerequisites in place, start by installing the Circles SDK package and ethers v6 in your project using npm.

npm i @circles-sdk/sdk @circles-sdk/data @circles-sdk/utils @circles-sdk/profiles @circles-sdk/adapter-ethers ethers

1. Add imports

Then, import the necessary interfaces from the Circles SDK and Ethers.

import { circlesConfig, Sdk } from '@circles-sdk/sdk';
import {BrowserProviderContractRunner} from "@circles-sdk/adapter-ethers"

• circlesConfig: Contains predefined configurations, such as contract addresses for different environments (production version).

• Sdk: The main Circles SDK class, which provides methods to interact with the protocol, including token transfers, trust relationships, and contract interactions.

Since we are using browser-based wallets like Rabby and MetaMask, we will import the BrowserProviderContractRunner adapter, which connects the Circles SDK with Ethers.js, enabling smart contract interactions through a browser-based Ethereum provider.

2. Add CirclesConfig for SDK

CirclesConfig defines the configuration settings needed to set up the SDK. You provide an object that follows this structure when initializing the SDK.

Circles is available on Gnosis Chain for production and sandbox version. You need to specify the correct contract addresses and service endpoints for each environment.

Property	Description
v2PathfinderUrl	The URL for the V2 Pathfinder service (if using V2).
pathfinderUrl	The URL for the Pathfinder service (used in V1).
circlesRpcUrl	The URL for the Circles RPC service
profileServiceUrl	The URL for the profile service that manages user profiles in Circles.
v1HubAddress	The contract address for the Circles V1 Hub.
v2HubAddress?	The contract address for the Circles V2 Hub.
nameRegistryAddress	The address of the name registry contract.
migrationAddress	The address used for migrating avatars and tokens from V1 to V2.
baseGroupMintPolicy	The address of the minting policy used for group avatars in Circles.
coreMemberGroupDeployer

Gnosis Chain

Circles contracts are deployed on Gnosis Chain mainnet. The below config is for applications that would be built in production environment.

import type {CirclesConfig} from "@circles-sdk/sdk";

export const GnosisChainConfig: CirclesConfig = {
    circlesRpcUrl: "https://rpc.aboutcircles.com/",
    pathfinderUrl: "https://pathfinder.aboutcircles.com",

};

RINGS - sandbox version of Circles

RINGS is a sandbox version of Circles protocol. If you are a builder or developer who is building on Circles for fun and want to see how the overall mechanics work - then this would be your place to begin.

import type {CirclesConfig} from "@circles-sdk/sdk";

export const circlesConfig: CirclesConfig = {
    circlesRpcUrl: "https://static.94.138.251.148.clients.your-server.de/rpc/",
    v1HubAddress: "0x29b9a7fbb8995b2423a71cc17cf9810798f6c543",
    v2HubAddress: "0x3D61f0A272eC69d65F5CFF097212079aaFDe8267",
    migrationAddress: "0x28141b6743c8569Ad8B20Ac09046Ba26F9Fb1c90",
    nameRegistryAddress: "0x8D1BEBbf5b8DFCef0F7E2039e4106A76Cb66f968",
    baseGroupMintPolicy: "0x79Cbc9C7077dF161b92a745345A6Ade3fC626A60",
    profileServiceUrl: "https://static.94.138.251.148.clients.your-server.de/profiles/",
};

3. Using Circles SDK Configuration

Circles contracts are deployed on the Gnosis Chain mainnet. The following configuration is intended for production-ready applications.

If you are building dApps on Circles SDK for hackathon or want to check sandbox deployments, then follow this segment to setup sandbox configuration for using the SDK.

You can seamlessly import the production-ready smart contract addresses directly from the Circles SDK, as they are already hardcoded within the SDK.

import { circlesConfig } from '@circles-sdk/sdk';

The circlesConfig object provides predefined contract addresses and service endpoints required for seamless integration with Circles on Gnosis Chain. It adheres to the CirclesConfig type from the Circles SDK.

Here's the configuration if you use CirclesConfig type from Circles SDK along with deployed contracts:

import type {CirclesConfig} from "@circles-sdk/sdk";

export const GnosisChainConfig: CirclesConfig = {
    circlesRpcUrl: "https://rpc.aboutcircles.com/",
    pathfinderUrl: "https://pathfinder.aboutcircles.com",
    v1HubAddress: "0x29b9a7fbb8995b2423a71cc17cf9810798f6c543",
    v2HubAddress: "0xc12C1E50ABB450d6205Ea2C3Fa861b3B834d13e8",
    nameRegistryAddress: "0xA27566fD89162cC3D40Cb59c87AAaA49B85F3474",
    migrationAddress: "0xD44B8dcFBaDfC78EA64c55B705BFc68199B56376",
    profileServiceUrl: "https://rpc.aboutcircles.com/profiles/",
};

Using the sandbox version of Circles SDK for builders

RINGS is a sandbox version of the Circles protocol designed for testing the Circles SDK without worrying about production requirements. If you are a builder or developer working on Circles for a hackathon and want to understand how the overall mechanics function, this is the place to start.

The only change you need to make to your codebase is updating the Circles configuration addresses to the sandbox contract addresses.

import type {CirclesConfig} from "@circles-sdk/sdk";

export const circlesConfig: CirclesConfig = {
    circlesRpcUrl: "https://static.94.138.251.148.clients.your-server.de/rpc/",
    v1HubAddress: "0x29b9a7fbb8995b2423a71cc17cf9810798f6c543",
    v2HubAddress: "0x3D61f0A272eC69d65F5CFF097212079aaFDe8267",
    migrationAddress: "0x28141b6743c8569Ad8B20Ac09046Ba26F9Fb1c90",
    nameRegistryAddress: "0x8D1BEBbf5b8DFCef0F7E2039e4106A76Cb66f968",
    baseGroupMintPolicy: "0x79Cbc9C7077dF161b92a745345A6Ade3fC626A60",
    profileServiceUrl: "https://static.94.138.251.148.clients.your-server.de/profiles/",
};

Once you have configured the sandbox addresses in your config.ts ,you can proceed with setting up the provider and signer as mentioned below.

4. Setup Provider and Signer

To setup provider and signer, we would utilize the Circles Adapter that is built to support transactions via ethers. Once you have already imported the BrowserProviderContractRunner , you would need to initialize it.

const adapter = new BrowserProviderContractRunner();
await adapter.init();

5. Initialize the Circles SDK

To initialize the CirclesSDK, we will pass on the circlesConfig and Adapter to SDK instance.

const sdk = new Sdk (adapter,circlesConfig); 
// or GnosisChainConfig as named in config

Once you have successfully created a SDK instance, you are all set to use Circles in your dApp.

Summary for the setup of Circles SDK

To quickly summarize how the entire setup of Circles SDK would look like if you are writing a script etc.

Installation

npm i @circles-sdk/sdk @circles-sdk/data @circles-sdk/utils @circles-sdk/profiles @circles-sdk/adapter-ethers ethers

Import the packages and setup script

import { circlesConfig, Sdk } from '@circles-sdk/sdk';
// or use the type import and then set up Circles contracts in configurations
// import type {CirclesConfig} from "@circles-sdk/sdk";
import {BrowserProviderContractRunner} from "@circles-sdk/adapter-ethers"

const adapter = new BrowserProviderContractRunner();
await adapter.init();

const sdk = new Sdk (adapter,circlesConfig); 
// or GnosisChainConfig as named in config

Optional : Setup deployed contracts based on production or sandbox version of Circles Protocol

Production version:

import type {CirclesConfig} from "@circles-sdk/sdk";

export const GnosisChainConfig: CirclesConfig = {
circlesRpcUrl: "https://rpc.aboutcircles.com/",
pathfinderUrl: "https://pathfinder.aboutcircles.com",
v1HubAddress: "0x29b9a7fbb8995b2423a71cc17cf9810798f6c543",
v2HubAddress: "0xc12C1E50ABB450d6205Ea2C3Fa861b3B834d13e8",
nameRegistryAddress: "0xA27566fD89162cC3D40Cb59c87AAaA49B85F3474",
migrationAddress: "0xD44B8dcFBaDfC78EA64c55B705BFc68199B56376",
profileServiceUrl: "https://rpc.aboutcircles.com/profiles/",
};

Sandbox version:

// For sandbox version
import type {CirclesConfig} from "@circles-sdk/sdk";

export const circlesConfig: CirclesConfig = {
    circlesRpcUrl: "https://static.94.138.251.148.clients.your-server.de/rpc/",
    v1HubAddress: "0x29b9a7fbb8995b2423a71cc17cf9810798f6c543",
    v2HubAddress: "0x3D61f0A272eC69d65F5CFF097212079aaFDe8267",
    migrationAddress: "0x28141b6743c8569Ad8B20Ac09046Ba26F9Fb1c90",
    nameRegistryAddress: "0x8D1BEBbf5b8DFCef0F7E2039e4106A76Cb66f968",
    baseGroupMintPolicy: "0x79Cbc9C7077dF161b92a745345A6Ade3fC626A60",
    profileServiceUrl: "https://static.94.138.251.148.clients.your-server.de/profiles/",
};

Voila 🎉 you're done with Circles SDK setup. Now, you can support Circles profiles and choose the Avatars that you would like to integrate and support their additional functions.

Choose which Avatar would you like to build on

Personal / Human Avatars

ERC-1155 standard avatars, which allows you to mint your personal Circles token (CRC) every hour, accumulating 24 CRC per day with an applied demurrage of 7%.

Group Avatars

Created by an owner, these avatars allow groups to trust human avatars within the group. Group tokens are utilized by collateralizing personal tokens, following the ERC-1155 standard.

Organization Avatars

As an organization, you are an avatar without any minting of new tokens. With your name and metadata file, which will be used for identification and can trust other avatars to receive Circles, with all owned Circles earned by avatars rather than minted.
