What is Salvium?
Salvium is a proof-of-work privacy blockchain launched in 2024 and built on Monero's code. It keeps payments private by default but adds staking, refundable payments and optional view keys, which the project pitches as a way for regulated exchanges to list a privacy coin.
Utility Lens
What Salvium actually does
Offers Monero-style private payments with extra tools, such as refunds and view keys, meant to make a privacy coin workable for regulated services.
- Real-world usage
- speculativeThe chain runs and ships features, but activity is small and trading liquidity is very thin.
- Token necessity
- essentialSAL pays fees, is the coin that is mined and staked, and is the asset moved in private transfers.
- Decentralization
- limitedMining is open to anyone with a CPU, but an anonymous core team controls development and a locked operations fund, and it has pushed several emergency hard forks.
- Track record
- developingLive since 2024; an inflation bug disclosed in January 2025 forced a full supply audit, and a 2026 spam attack needed mandatory hard forks.
What it’s used for
Holders send SAL privately, mine it with ordinary CPUs and lock it for about 30 days to earn a share of block rewards. Since April 2026 users can also mint their own private tokens on the chain. Trading is very thin and limited to a few offshore venues; the project lists MEXC, NonKYC and CoinEx.

- A March 2025 supply audit found that about 9.46 million SAL had been minted without authorization and sold through exchanges. Source (opens in a new tab)
- Version 1.1.3c, released in July 2026, was a mandatory hard fork to repair node database problems caused by a spam attack. Source (opens in a new tab)
Privacy: what’s hidden, what isn’t
- Privacy model
- default (every transaction)
- What it hides
- Sender, receiver and amount of SAL transfers and of tokens created with Salvium Assets.
- What stays visible
- That a transaction happened, when and its fee; anything a holder chooses to reveal through a view-only wallet; and metadata that token creators publish on-chain.
- Reality check
- Senders are hidden within a ring rather than the whole chain, and Salvium's inflation bug showed that hidden amounts can also hide extra coins until an audit is done. The project says SAL can list on MiCA-regulated exchanges, but no regulator has confirmed that, and Coinbase does not offer it.
How Salvium works
Salvium starts from Monero's privacy toolkit. A ring signature hides the real sender among a group of plausible signers, a one-time stealth address shields the recipient, and Ring Confidential Transactions keep the amount hidden. Blocks come every two minutes and are mined with RandomX, the same CPU-friendly algorithm Monero uses. On top of that, holders can stake SAL: staked coins are locked for 21,600 blocks, roughly 30 days, and stakers share 20% of each block reward.
In October 2025 the Salvium One upgrade moved every wallet to Carrot, an address scheme designed for Monero. It also added SPARC, which lets a business send an unwanted deposit back to the sender without learning who that sender is, and T-CLSAG, a modified ring signature that the project submitted to Cypher Stack for a cryptographic audit. View-only wallets can show incoming and outgoing payments to an auditor the owner chooses.
A further upgrade in April 2026 introduced Salvium Assets, which let anyone mint a token on the chain with the same privacy as SAL. The project is clear that Salvium has no smart contracts or EVM yet; token labels follow Ethereum-style metadata standards only so outside tools can read them. The team says its design allows listing on EU exchanges that follow MiCA rules, citing a legal opinion it commissioned, though that is the project's claim and not a regulator's ruling.
Key moments
- 2024Salvium goes live as a proof-of-work privacy chain built on Monero's code, with native staking from the start.
- 2025In January the team discloses a bug that let an attacker mint coins without authorization; a supply audit finishes in March.
- 2025The Salvium One upgrade brings Carrot addresses and SPARC refunds on October 13.
- 2026Salvium Assets go live at block 465,000 in April, and a mandatory release in July repairs damage from a spam attack.
Supply
The main supply is capped at 184.4 million SAL, and once that is reached miners keep earning 3 SAL in every block indefinitely. About 12% was premined, split into a 3.53% build fund and an 8.48% operations fund released over 24 months. The project says the exploit pushed roughly 9.46 million SAL into circulation early but did not raise the 184.4 million cap.
Risks to understand
- Trading is extremely thin and limited to a few offshore exchanges, and Coinbase does not offer SAL.
- A bug disclosed in January 2025 let an attacker mint about 9.46 million SAL without authorization, which only a supply audit could confirm.
- A 2026 spam attack left some coins temporarily unspendable and required mandatory hard forks.
- The core team is anonymous and also controls the premined operations fund.
- The project's compliance features do not guarantee listings: from July 10, 2027 EU-regulated providers may not handle anonymity-enhancing coins, and how that applies to SAL has not been settled by any regulator.
Salvium FAQ
Is Salvium a fork of Monero?
Yes. Salvium is built on Monero's codebase and keeps its ring signatures, stealth addresses and hidden amounts, then adds staking, refunds and view keys.
What happened in Salvium's 2025 supply audit?
A bug let an attacker mint coins without authorization. The project says its March 2025 audit found about 9.46 million SAL had entered circulation early and blacklisted 382,600 coins the attacker tried to pass through.
Can I stake SAL?
Yes. Staked SAL is locked for 21,600 blocks, about 30 days, and stakers share 20% of block rewards.
Is Salvium MiCA-compliant?
The project says an independent legal opinion found SAL eligible for MiCA-authorised exchanges. That is the project's claim; no regulator has ruled on it.
