Our verdict on Mercurial
6.0/10Mercurial suits Solana users who want to swap or provide liquidity in stablecoins and other stable-value assets. Its main strength is a focused design around pools and vaults for assets that should trade near parity, backed by public open-source code. The main caveat is that current information is thin: most coverage dates from 2021, and fees, audits and team details are not published in the sources reviewed. Verify the live app, audits and pool terms before depositing.

What is Mercurial?
Mercurial Finance is a decentralized finance protocol on Solana focused on stable assets. A 2021 news report describes it as a protocol for storing, exchanging and issuing stablecoins. A token listing describes it as a platform of pools and vaults for stable swaps.
The project was reported to have funding from Alameda Research, the Solana Ecosystem Fund, OKEx and Huobi. Its MER governance token was offered through an FTX initial exchange offering in May 2021. In September 2021, it launched a liquidity pool for Wormhole wrapped stablecoins.
The homepage could not be reviewed, and most outside coverage is several years old. Readers should confirm the current status of the product on the live app before relying on any of these details.
How Mercurial works
Mercurial runs automated market-making pools on Solana. A liquidity pool is a smart contract holding several tokens, and users swap against it rather than against another trader. Liquidity providers deposit assets and earn a share of trading fees.
The pools are designed for stable assets, meaning tokens meant to hold the same value, such as different dollar stablecoins. A stable-swap pool uses a curve that keeps prices close to parity, so large swaps move the price less than in a standard pool.
The project also offers vaults and a governance token, MER. Vaults let users place assets into a managed strategy instead of managing positions themselves. MER holders are meant to take part in protocol governance, though the sources reviewed give no detail on voting or token utility.
6 features
Key features
01
Stable-asset swap pools
Pools hold assets meant to trade near the same price, such as different dollar stablecoins. The design aims to reduce slippage compared with general-purpose pools.
02
Multi-asset pools
A pool that held multiple stablecoins at once was demonstrated in a Solana tutorial. This lets users swap between several dollar assets from one pool.
03
Vaults
The platform also offers vaults, which let users store assets in a managed strategy. Details of each strategy are not given in the sources reviewed.
04
Wormhole stablecoin pool
A pool for Wormhole wrapped stablecoin assets launched in September 2021. It targeted liquidity for bridged stablecoins on Solana.
05
MER governance token
MER is the governance token. Its supply and utility details are not covered in the sources reviewed.
06
Open-source code
The GitHub organisation has public repositories including stable-swap pool instructions, a JavaScript SDK and a Merkle distributor contract.
Pros and cons
What we like
- Focused niche: swaps between assets meant to hold the same value, which suits stablecoin traders
- Runs on Solana, so transaction costs are typically low
- Public GitHub code covers pool instructions, an SDK and token distribution contracts
- Early backing from established crypto investors was reported at launch
- Added support for Wormhole wrapped stablecoins, useful for users moving assets across chains
Watch out for
- Most available coverage dates from 2021, so the current state of the product is unclear
- Fee levels, audit reports and team details are not published in the sources reviewed
- Stablecoin pools carry depeg risk, especially for bridged or wrapped assets
- Smart-contract risk applies to every pool and vault, as with any on-chain protocol
- The MER token's sale was tied to an exchange offering with staking and verification requirements, which shaped its early distribution
Mercurial fees
Mercurial's fee schedule is not published in the sources reviewed. Pool swap fees, vault fees and any performance charges would be shown on the app's pool and vault pages.
On Solana, users also pay network transaction fees, which are paid in SOL and are generally small. Check each pool's displayed fee before swapping or depositing.
Is Mercurial safe?
The sources reviewed do not name any audits, insurance or bug bounty. Users should look for audit reports before depositing. Pools and vaults are smart contracts, so a bug or exploit could cause losses, and depositors keep custody of their own wallets rather than relying on a company.
Stable-asset pools have their own risk: if one token loses its peg, liquidity providers can end up holding mostly the weakened asset. Wrapped or bridged stablecoins add bridge risk on top. No regulatory status or incident history is published in the sources reviewed.
6 steps
How to get started with Mercurial
- 1
Find the official Mercurial site through its GitHub organisation or a trusted listing, and avoid look-alike links.
- 2
Install a Solana wallet and fund it with a small amount of SOL for network fees.
- 3
Review the pool or vault you want to use, including the assets it holds and the stated fees.
- 4
Look for audit reports and check how the pool treats bridged or wrapped assets.
- 5
Start with a small swap or deposit to confirm the process works as expected.
- 6
Monitor pool balances and stablecoin prices, and withdraw if an asset depegs.
Who Mercurial is for
Mercurial is for DeFi users on Solana who are comfortable with wallets and smart-contract risk and want low-slippage swaps or yield on stablecoins. It is less suited to beginners or anyone who needs documented audits and fee schedules before using a protocol.
