Smoothy Review 2026: Single-Pool Stablecoin DEX

Smoothy is a decentralized exchange protocol that holds same-backed assets, such as stablecoins, in a single liquidity pool. DefiLlama describes it as offering low-cost, zero-slippage swapping and maximized interest earning. It lists the project on Ethereum and BNB Chain under the Dexs category.

The project has a governance token, SMTY, and DefiLlama lists two audits. Public reporting shows documentation pages on swaps, gas optimization, token flexibility and LP incentives, mostly dated from early 2021.

Current scale is small. DefiLlama shows about $180,000 in TVL with a 32.8% drop over seven days, and SMTY has a market cap in the tens of thousands of dollars according to a price tracker. Its homepage in the data is nearly empty, so we cannot confirm recent development.

Most DEXs use many separate pools, each holding a pair of tokens. Smoothy instead puts several assets that track the same value, such as dollar stablecoins, into one pool. Because the tokens are meant to be worth the same, the pool can price swaps between them with very little slippage.

Liquidity providers deposit tokens into the pool and receive LP tokens. They earn from swap fees and, according to the project description, from interest generated on pooled assets. The docs also describe incentives paid on LP tokens, which in the past were paid in SMTY.

The tradeoff is concentration of risk. All assets share one pool, so if one stablecoin loses its peg, the pool can be drained of the healthy assets and LPs bear the loss.

Swap fees, withdrawal fees and LP yield figures are not published. The project describes its swaps as low-cost, but gives no percentage.

Users would see the actual fee in the swap interface before confirming and in the project documentation. Network gas fees on Ethereum or BNB Chain are separate and depend on congestion.

DefiLlama lists two audits, but the auditors and findings are not given publicly. Smoothy is a non-custodial smart-contract protocol, so users keep their tokens in their wallets until they deposit. Deposits are exposed to smart-contract bugs and to depeg risk of any asset in the shared pool.

Low and falling TVL suggests limited usage, and the project does not show recent updates, so maintenance status is unclear. No hacks or incidents are mentioned, but absence from public sources are not proof none occurred. Check the project's official channels before depositing.

Smoothy is for experienced DeFi users who understand stablecoin pools, LP tokens and depeg risk, and who want to examine a single-pool design. It is a poor fit for beginners or anyone needing deep liquidity for large swaps.
