Overview

Smart Invoice is an open-source, non-custodial escrow protocol designed to address payment insecurity in the Web3 ecosystem. Developed initially for RaidGuild, Smart Invoice emerged from countless stories of freelancers left unpaid, despite completed work. By combining a smart contract-powered escrow with optional arbitration, we enable secure payments for freelancers, DAOs, and Web3-native organizations.

How It Works

Unlike traditional escrow services, Smart Invoice leverages blockchain technology to provide a transparent, automated, and decentralized payment solution. Funds are held in smart contracts, accessible only when predefined project milestones are met. Clients and freelancers enjoy a familiar payment flow, yet with Web3's enhanced speed and security. We integrate dispute resolution through three arbitration providers:

1. In-house arbitration as cost-effective option for low value transactions
2. Kleros for multi-network production grade and specialised arbitration support
3. LexDAO as battle tested legacy arbitration option.

Taken together, we are offering a comprehensive framework for risk management without the need for custodial accounts.

## Use Cases

Smart Invoice addresses payment pain points for freelancers, project teams, and grant-based contracts across multiple blockchains. The protocol supports Polygon, Ethereum Mainnet, Gnosis Chain, Arbitrum. Optimism, and Base. Our core features are:

• Milestone-based payments
• Dispute resolution and arbitration
• Safety valve for fund recovery
• Seamless invoicing and payment tracking

Latest Updates and Future Plans

After onboarding Kleros earlier this year and extending our network support, we are now finalising an integration with the Nouns Builder DAO's Proposal Builder.
