Welcome to Sigmoid — the decentralized platform where creators turn their work into shareable assets, fans become stakeholders, and royalties flow transparently and automatically. Whether you’re a musician, filmmaker, writer, or artist, Sigmoid enables you to tokenize your creative projects and build a community-powered economy around them.

Imagine MrBeast launches a viral Willy Wonka’s Chocolate Factory video. Instead of only relying on ad revenue, he tokenizes the video by creating 1,000 ownership shares:
- Keeps 600 shares for himself
- Offers 400 shares to fans at $1 per share
As royalties roll in (from YouTube ads, Spotify streams, licensing deals, etc.), shareholders get paid — automatically, transparently, and directly to their wallets.
This is the future of creative monetization.
Creators Artists, musicians, filmmakers, writers — anyone who wants to tokenize their work and create new revenue streams with their fans.
Investors Fans, collectors, and supporters who want to buy into creative projects and earn royalties alongside their favorite creators.
Developers Builders and hackers looking to integrate with our smart contracts, build dApps, or extend the platform in new directions.
Businesses Agencies, labels, and rights-holders curious about how Web3 tokenization can unlock new monetization models.

Track your investments and returns with powerful on-chain insights.
// Get all your asset shares
const myShares = await contract.getAllAssetShares();
// Check specific asset shares
const shares = await contract.getUserShares(yourAddress, assetId);
Key Metrics:
- Total Investment
- Current Valuation
- Total Royalty Earnings
- Return on Investment (ROI)
Recommended Allocation:
- 60% - Established creators (lower risk)
- 30% - Growth opportunities (medium risk)
- 10% - Experimental or high-risk assets
Asset Diversification:
- Spread across asset types (music, video, art)
- Mix of mainstream and niche categories
- Balance short-term trends with long-term value
We integrated Tomo Wallet to provide a seamless and secure web3 login and transaction experience for our users. This integration allowed us to support multiple EVM chains effortlessly, including Ethereum, Polygon, Arbitrum, Optimism, Base, and more.
-
We used the
@tomo-inc/tomo-evm-kitlibrary to add wallet login and EVM chain support to our frontend. -
With the help of TomoEVMKitProvider, we wrapped our app to initialize the wallet context:
import { TomoEVMKitProvider, getDefaultConfig } from '@tomo-inc/tomo-evm-kit'; import { WagmiProvider } from 'wagmi'; const config = getDefaultConfig({ appName: 'YourApp', projectId: '<your-walletconnect-project-id>', chains: [mainnet, polygon, arbitrum, optimism, base], }); <WagmiProvider config={config}> <TomoEVMKitProvider> {/* your app components */} </TomoEVMKitProvider> </WagmiProvider>
-
We added support for social logins (Google, Apple, Twitter, etc.) using Tomo’s prebuilt authentication UI.
-
Tomo handled user wallet creation, signing, and message verification under the hood with a simplified UX.
- Easy Onboarding: Users could log in with just a Google or Apple account — no need to install browser extensions or manage seed phrases.
- Multi-chain Support: Enabled smooth interactions across different EVM-compatible chains.
- Gasless UX (optional): Tomo supports abstracted transactions with paymaster integrations.
- Time-Saving: Reduced integration time drastically compared to building a custom wallet auth system.
- Security: Authenticated and encrypted key management via Tomo's secure backend.
How It Works:
- Revenue is generated from external platforms (YouTube, Spotify, licensing)
- Creator deposits royalties into the smart contract
- Snapshot of shareholders is taken
- Each holder claims their share
Claiming Example:
// Get distributions
const distributions = await contract.getAllDistributions(assetId);
// Claim from the latest distribution
const tx = await contract.claimRoyalties(assetId, 0);
await tx.wait();Active Strategies:
- Vote on asset verification
- Invest early in promising assets
- Engage with creators and communities
Passive Strategies:
- Buy and hold
- Diversify
- Reinvest royalties
Types of Risk:
- Market Risk: Creator popularity and asset value may fluctuate
- Technical Risk: Smart contract bugs, blockchain issues
- Liquidity Risk: Currently no secondary share market
Risk Mitigation Tips:
- Diversify across creators and asset types
- Start with small investments
- Research creator history and community engagement
- Stay updated with platform news
