Fe - the syntax is inspired by Python and Rust. It is easy to learn, even for those who have never dealt with the ethereum virtual machine (evm) before; designed to be safe and equipped with the tooling needed to validate contracts; uses the same intermediate language as Solidity (YUL), making it a great choice not only for the ethereum mainnet, but also for (upcoming) layer two chains.

Vyper - a more recently developed language, similar to Serpent and again with Python-like syntax. Intended to get closer to a pure-functional Python-like language than Serpent, but not to replace Serpent.

Serpent - a procedural (imperative) programming language with a syntax similar to Python. Can also be used to write functional (declarative) code, though it is not entirely free of side effects.

Bamboo - a language influenced by Erlang, with explicit state transitions and without iterative flows (loops). Intended to reduce side effects and increase auditability.

YUL - official "intermediate" assembly language for the ethereum virtual machine (evm)

Yul (previously also called JULIA or IULIA) is an intermediate language that can be compiled to bytecode for different backends.

It can be used in stand-alone mode and for "inline assembly" inside Solidity. The compiler uses Yul as an intermediate language in the IR-based code generator ("new codegen" or "IR-based codegen"). Yul is a good target for high-level optimisation stages that can benefit all target platforms equally.

Low-level Lisp-like Language / Lisp Like Language (LLL) - a functional (declarative) programming language, with Lisp-like syntax. It was the first "intermediate" assembly language for ethereum contracts.
