Rainlang: DeFi's Native Language

Project Background

Rainlang is the native language of DeFi. It is designed to make smart contracts accessible to a wider audience. If you know your way around a spreadsheet, you can learn Rain. Rainlang is parsed and interpreted onchain, permissionlessly extensible, and completely immutable - with no admin keys or upgradeable contracts.

The Challenge

• A very small group of people can actually read and write smart contracts
• Current solutions rely heavily on third-party verification
• Upgradeability introduces centralization risks
• Complex syntax and compilation processes create barriers to entry

Key Features

Innovative Design

• Interpreted Onchain: No compilation necessary
• Extensible: Add your own words permissionlessly
• Immutable: No admin keys or upgrades
• Gas Efficient: Comparable to optimized Solidity

Security Model

• Based on Lindy effect and user choice
• No reliance on third-party verification
• Community-driven security through transparency
• Self-auditable expressions

Impact

• Makes smart contracts accessible to spreadsheet-level users
• Enables true decentralization through readable code
• Creates new possibilities for DeFi applications
• Reduces reliance on centralized verification systems
