### Helios
Helios is also a brand new language. One notable implementation difference
is that it's compiler is written in a [single javascript file](https://github.com/Hyperion-BT/Helios/blob/main/helios.js). According to the creator, the intention of that was to make the compiler implementation easier to audit.
is that it's compiler is written in a [single javascript file without dependencies](https://github.com/Hyperion-BT/Helios/blob/main/helios.js).
According to the creator, the intention of that was to make the compiler implementation easier to audit.
As a language, Helios is also purely functional but **does not** have type inference. According to the creator, this is to make contracts easier to audit. It also supports custom types similar to records and enums.

Another interesting thing is that because the compiler is a single javascript file it's pretty easy to use Helios from within a javascript project.

### plu-ts
plu-ts is **not** a new language. You can consider it an embedded DSL for creating smart contracts with Typescript. Because of this it's a bit closer to Plutarch conceptually than Aiken or Helios.
plu-ts is **not** a new language. You can consider it an embedded DSL for creating smart contracts with Typescript.
Because of this it's a bit closer to Plutarch conceptually than Aiken or Helios.
It implements it's own type system and at compile time (js runtime) checks the types to be correct.
### Scalus
A Scala implementation of Plutus.
Scalus is a set of libraries to work with Cardano Untyped Plutus Core that works on both JVM and JavaScript. This includes:
- Untyped Plutus Core (UPLC) data types and functions
- Flat, CBOR, JSON serialization
- CEK UPLC evaluation machine including execution cost calculation
- UPLC parser and pretty printer
- Type safe UPLC expression builder, think of Plutarch
- Macros to generate UPLC code from Scala code, think of PlutusTx but simpler
