💧 Rainlang 💧

Rainlang is an onchain smart contract language for any EVM, designed to be much easier to read and write.

Rainlang is:

  • parsed onchain (by a smart contract)
  • interpreted onchain (by a smart contract)
  • permissionlessly extensible (add your own words to the language)
  • immutable (none of the contracts are upgradable or have admin keys)

Raindex

Raindex is a new kind of DEX, where all of the orders are smart contracts written in Rainlang. Think perpetual, algorithmic strategies.
