xExchange

Rejected venues wait the longest for re-review; a rejection has to earn another look before the scheduled date.

xExchange is the automated market maker DEX on MultiversX, built by the same team that built the chain. Its pools pair two tokens and rebalance against traders, so a depositor’s holdings drift toward whichever asset falls. That is impermanent loss, and it cannot be explained to a client in two sentences or defended after it bites. The class rule rejects the whole AMM category on those grounds, whatever the quality of the venue. TVL was about $3.07 million at the 2026-08-15 survey. A product line without impermanent-loss exposure would reopen the file.

The research file

Mechanism applicability

xExchange is a MultiversX automated market maker using the constant-product x*y=k formula. Liquidity providers contribute paired assets, receive LP tokens representing their pool share, and earn part of the 0.3% swap fee. As trades alter the two reserves, an LP continuously sells the outperforming asset for the underperforming one; the return therefore depends on relative prices and directly matches the shared v1 amm-lp dossier.

Current observation and lifecycle

The DefiLlama protocol API read on 2026-08-15 classified xExchange as a DEX and reported approximately $3.07M on the chain it labels Elrond, the former name of MultiversX. Current official documentation and the live app continue to offer swaps, liquidity pools, farms, staking, and governance. The record is active, and the canonical registry perimeter remains MultiversX.

Control and exit applicability

LPs exit by removing their proportional share of the pool after its reserve mix has changed; there is no principal guarantee or mechanism restoring the originally deposited quantities. MEX Energy holders can pass xEIPs through onchain votes, but the documentation says the xExchange team implements approved feasible proposals. Governance, pool depth, contract execution, token price divergence, and farm incentives affect the position without removing its defining inventory-rebalancing exposure.

Why the class rule decides

The proposed exposure is the LP token itself, and the current constant-product mechanism necessarily creates relative-price inventory drift. The shared v1 amm-lp dossier therefore decides regardless of the venue’s current TVL, fee income, governance, or operating history. Reopen only if xExchange ships a materially distinct non-LP product without impermanent-loss exposure; then review that product’s mechanism, controls, incidents, exit depth, legal access, and named alternatives independently.

Inherited controls

The verdict above grades the protocol layer. Every position also inherits the asset it holds and the chain it settles on. The least safe layer sets the position’s grade, and the position table names which one that is.
