We will be publishing more write ups, benchmarks and technical deep dives on Jai to UPLC, APLC and our optimisation strategies. If you care about performance and accessibility in Cardano smart contracts, this is just the beginning Watch the full video 👇 https://t.co/4rneXH2nsC

Today this Jai → UPLC toolchain powers VyFi’s V3 DEX and products like SafeSwap, giving us high performance Plutus v3 contracts and a much better dev loop: hot reloading, super fast builds and unified on-chain/off-chain development

We consciously skipped Plutus IR for this work. Part of the goal was to deeply understand the platform itself and eliminate tooling layers that hide what is really happening. Fewer moving parts, more clarity, faster iteration

APLC also lets us decompile UPLC into a readable form, so we can inspect contracts on chain, understand others’ approaches and validate our own output. It becomes a practical lens on Plutus rather than a black box

Loop sharing lets us emit a single shared unrolled loop for multiple logical loops, parameterised via tagged data. The CEK machine only has to evaluate that structure once, while we still pack in a lot of logic inside a single validator

We also use smart data representation with const and case, minimising repeated packing/unpacking of large structures like values, inputs and outputs. The result in practice: roughly 5x–10x CPU reduction and about 2x memory reduction on many validators

Key insight: the main bottleneck is often structure, not just built in costs. Y combinator style recursion can be very expensive on the CEK machine. Bounded loop unrolling and smarter structure drastically reduce CPU and memory usage

Our pipeline: Jai → CFG → SSA → three address code → APLC (Advanced Plutus Core, a sane Plutus-like IR) → UPLC. Along the way we apply optimisations like tail call optimisation, loop unrolling, hoisting and more

By plugging directly into the Jai compiler, we grab the AST and translate it straight to UPLC. This gave us precise control over generated Plutus and showed that mapping an imperative language to lambda calculus can actually work really well

Instead of accepting existing stacks as gospel, we stripped away “accidental complexity”. That led us to Jai, a language Skylar had used professionally for years: fast to compile, powerful type system, rich metaprogramming and a first class compiler API

So Skylar treated the node like a black box and used “experimental archaeology”, pushing raw UPLC into transactions and observing behaviour. What actually works on chain? What does Plutus v3 really support? What is truly allowed and efficient

A big pain point was discoverability. Key details about what Plutus can actually do are scattered across different tools and libraries. To optimise properly, you need to understand the real platform, not just the wrappers around it

The challenge: to deliver a feature-rich V3 DEX with real on-chain decentralisation, we needed far more logic on chain. That quickly exposed the high cost and complexity of Plutus as used through existing toolchains

At UPLC Programming Language Conference 2025, our CIO Skylar-Ray O’Quinn shared “From Jai to UPLC: An Unlikely Toolchain” The story of how necessity pushed VyFi to rethink how we build complex Plutus smart contracts on Cardano 🧵
