eUTxO In the Wild
From DEXes to governance, eUTxO powers real applications across multiple chains.
Decentralized Exchanges
Order-book and AMM DEXes leverage UTxO parallelism for batched order processing. Swap outcomes are deterministic before submission — though batcher-mediated ordering shifts MEV concerns rather than removing them.
Governance & Voting
Cardano governance (CIP-1694) tracks votes as on-chain certificates from registered DReps. Off-chain frameworks like Agora model proposals as eUTxO state machines: the proposal lives in a UTxO with datum tracking vote tallies, advanced by transactions that carry the voter's signature as a redeemer.
Native Tokens & NFTs
Custom tokens are native in eUTxO, not smart contracts. They live directly in UTXOs, making them cheaper and more efficient.
State Machines
eUTxO naturally models state machines: datum = state, redeemer = input, validator = transition function.
Chains Using Extended UTxO
Cardano: the flagship with Plutus/Aiken. Ergo: UTxO + Sigma protocols. Nervos CKB: the Cell Model. The paradigm is growing beyond a single chain.
