Sovryn Dex

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

Sovryn Dex is the trading arm of Sovryn, a non-custodial bitcoin lending, borrowing, and margin trading system on Rootstock. Its pools are AMM liquidity positions: a depositor holds both sides of a pair, and when the pair’s prices diverge the position ends up worth less than simply holding the assets. That impermanent loss cannot be explained to a client in two sentences and is indefensible when it bites, so the class rule rejects every AMM pool regardless of protocol quality. TVL stood near $3.1M at the 2026-08-14 survey. The file reopens only if Sovryn ships a product without impermanent-loss exposure.

The research file

Mechanism applicability

Sovryn describes its exchange liquidity as an automated market maker in which users supply tokens to active pools, receive LP tokens representing their pool share and earn trading fees. Its DAMM documentation explicitly describes multi-asset exposure and impermanent loss when contract balances diverge from staked balances. Those are the defining facts of the shared v1 amm-lp dossier even where a pool permits single-sided entry.

Current observation and perimeter

The DefiLlama protocol API read on 2026-08-15 classified Sovryn Dex as a DEX and reported approximately $7.11M TVL, about $6.83M on Rootstock and $0.29M on BOB. Current Sovryn market-making instructions remain live on Rootstock. The registry perimeter is therefore updated from Rootstock-only to Rootstock and BOB; the classification remains fundamental despite the larger TVL than the prior survey.

Control and exit applicability

LP tokens are the user’s receipt and can be redeemed, and Sovryn says liquidity may generally be withdrawn at any time for transaction cost. That exit returns the pool’s current inventory, not the originally deposited mix, so timing can crystallize impermanent loss. Sovryn documentation says AMM smart contracts are under Bitocracy governance, adding governance and contract-change exposure without curing the inventory risk.

Why the class rule decides

The live product remains market-making: trades move pool inventory, fees compensate LPs, and relative-price moves can reduce value versus holding. Single-sided entry and dynamic weights mitigate implementation details but do not eliminate the loss path documented by Sovryn itself. The shared v1 amm-lp dossier therefore decides. Reopen only for a distinct Sovryn product whose return does not require paired or synthetic market-making inventory, with independently verified contracts, cash flows and proposed-size exits.

The claims above trace to these. Where a number could not be independently verified, the thesis says so.

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.
