Solanium

Solanium is a crypto launchpad on Solana, where new projects sell tokens to the public before they list. It is not the Solanium plant resource from the game No Man's Sky. You lock the SLIM token to get xSLIM, a staking score that sets how much you can buy in each sale. Sales are paid in USDC and usually need an identity check.

Solanium held its own public sale in May 2021 and now calls itself a multichain launchpad, with sales for projects on Arbitrum, BNB Chain, Polygon and HyperEVM. Activity has slowed. The most recent sale on its blog was Harmonix Finance in December 2025, and on 7 October 2026 the homepage showed "Project coming soon".

How the Solanium launchpad works: SLIM staking and xSLIM

You take part in Solanium sales by locking SLIM, and the lock gives you xSLIM. xSLIM is a score, not a coin: the staking docs say it cannot be transferred. The more SLIM you lock and the longer you lock it, the more xSLIM you hold.

The longest lock is one year. Solanium's original tiers post gives the ratio: one SLIM locked for a full year gives one xSLIM, and half a year gives half that. The balance then falls in a straight line each day until the lock ends. The model is borrowed from Curve's vote-locking design, according to the same post.

Here is the worked example Solanium uses. Lock 1,000 SLIM for three months and you start with 250 xSLIM. That score shrinks a little every day. To keep it up, you extend the lock or add more SLIM. Both are allowed.

You cannot leave early. The docs state that locked SLIM "can not be withdrawn before the timelock has expired". Plan for that before you pick a lock length.

When staking opened, Solanium also let you stake liquidity pool tokens from Raydium RAY$1.88+4.5% for a 2.5 times xSLIM bonus, per its staking launch post.

That option was not on the staking page when we checked on 7 October 2026. The page offered plain SLIM staking only.

Solanium tiers and lottery tickets were removed in December 2024

Solanium no longer uses tiers. Many guides still describe five tiers from 100 to 50,000 xSLIM, with a lottery for the lower three. That was the 2021 design. Solanium's platform update of 13 December 2024 removed both the tiers and the lottery tickets.

The rule since then is simpler: more xSLIM means a bigger allocation. Each sale sets its own minimum xSLIM to join. The update gave 100 xSLIM as an example. The Harmonix Finance sale in December 2025 asked for 500.

The same update changed two other things you should know about:

• One large stake beats several small ones. Solanium says 200 xSLIM in one account earns more allocation than two accounts with 100 each.
• "Social pools", which gave access through social media tasks, were dropped.

A snapshot of xSLIM balances is taken when a sale starts. You can add to your stake up to that point.

Solanium Shield: refunds when a token falls below its IDO price

Solanium Shield is a refund scheme for sales that carry the Shield badge. If the new token trades below its sale price soon after launch, buyers who have not moved their tokens can send them back for most of their money.

The terms change from sale to sale. The general Shield page describes a refund of up to 90% for fully unlocked tokens that fall below the sale price within a week. For Harmonix Finance, the window was 12 hours after the token launched and the refund was 90% of the USDC paid, per the sale announcement.

Two limits matter. You lose the right to a refund the moment you move or sell any of the tokens, even if you buy them back. And Shield covers only a short window. It does nothing for a token that holds up at first and slides a month later.

KYC, restricted countries and wallets for multichain sales

Most Solanium sales ask you to prove who you are, and many countries are shut out. The Harmonix sale used a two-step check: a selfie and a photo of your ID. You only had to pass it if you won a share of the sale and had not been checked before.

The list of blocked places is long. Solanium's terms bar every European Union member state, along with places under sanctions. The Harmonix sale also shut out all EU and EEA countries, China, and dozens of others. The terms forbid using a VPN to get around this. Read the list on each sale page before you stake.

Your stake always lives on Solana, and Harmonix was paid for in USDC on Solana. The tokens you buy may arrive on another chain. For those sales you give a second wallet address when you sign up. Solanium's Arbitrum guide from March 2024 walks through the steps.

Recent IDOs and node sales on the Solanium launchpad

Solanium's sale calendar has thinned out. Its blog records seven sales in 2024 and 2025, and none since December 2025:

Harmonix Finance was the first HyperEVM project to sell on Solanium. Its hard cap was $120,000 in USDC, according to the announcement. That is a small raise, and it tells you roughly how much allocation there is to share among stakers.

The full history, with the amount raised and price for each sale, is on Solanium's own projects page.

SLIM token: supply, utility and where the Solanium coin trades

SLIM is Solanium's token on Solana. Its main use is staking for xSLIM, which gives sale access and voting weight. The total supply is fixed at 100 million SLIM, per the tokenomics docs.

SLIM was sold to the public at $0.20 in May 2021, with private rounds priced a little lower. Locked tokens were held in Bonfida vesting contracts, the docs say.

The docs also describe fees. Each sale pool sends a fixed share of the money raised to xSLIM holders and a share of the tokens to a governance treasury. The pools page uses 2% for each as its example. Those docs were written around launch, and we could not confirm what fees recent sales paid out.

Solanium's homepage links to SLIM markets on MEXC, Gate and Jupiter. The price widget on this page shows the live figure.

Who Solanium is for

Solanium suits a narrow group: people who want early token sales from vetted projects, live outside its restricted countries, and will lock SLIM for months to get them.

It is a poor fit in a few common cases:

• You live in the EU or EEA. Recent sales have excluded you.
• You want to stay anonymous. Most sales need a selfie and ID.
• You want to exit quickly. A lock cannot be broken early, and SLIM's price can move a long way during a year.
• You want a steady flow of sales. There was a gap of about a year between Kat Kafe and Harmonix Finance.

The real cost of joining is holding SLIM through the lock. Weigh that against how many sales you expect to get into, and how large the allocations are.

Is Solanium safe? Risks to weigh before you stake SLIM

The main risks with Solanium are the lock on your SLIM, the lack of a published audit, and the small number of recent sales. None of these is a known exploit. We found no report of Solanium's staking or sale contracts being hacked.

Solanium's docs and website do not link to a security audit of its programs. The risks page says only that hackers "may attempt to interfere" with the platform. Solanium does not publish its program addresses in its docs either, so we could not check who is able to upgrade the staking program. Treat both as unknowns.

Your locked SLIM sits in Solanium's staking program until the timer ends. If something went wrong with the platform during that time, you would have no way to pull out early.

Sale tokens carry their own risk. Solanium picks and reviews projects, and stakers can vote on launches, but early-stage tokens often fall after listing. Shield softens that for a few hours or days only.

Governance is partly off-chain. The governance docs call the first phase "a mix between a centralized solution and blockchain voting". The operating company, Solanium Limited, also reserves the right in its terms to change or discontinue the service without notice.

Some early features are gone or were never finished. The docs describe a trading screen built on the Serum exchange. On 7 October 2026 the site menu showed only Stake, Projects and Dashboard.

Solanium alternatives: Pump.fun and MetaDAO

Solanium is a curated, stake-to-access launchpad. The busier Solana launch platforms work on different rules, and neither asks you to lock a platform token.

Pump.fun is open to everyone. Its terms say it "lets anyone create coins, giving everyone equal access to buy and sell from the start". There is no project review and no refund scheme. You get speed and openness, and you do your own vetting.

MetaDAO META$4,588.52+6.7% describes itself in its docs as "a fundraising and governance platform" for founders and their communities. Its sales put key project assets under market-driven governance. That is a different kind of buyer protection from Shield: it aims to limit what a team can do with the money over time, where Shield offers a one-off refund window.

Solanium's edge over both is the mix of project screening, identity checks and Shield. Its weakness is the lock-up and the thin calendar.

Solanium history and the company behind it

Solanium started in 2021 as a launchpad built only for Solana. The public SLIM sale ran that May, per the project FAQ. Staking opened in beta a month later, alongside the five-tier system.

Solanium then grew beyond Solana. By early 2024 it had run sales on BNB Chain, Polygon and Arbitrum, its Arbitrum guide says. Shield was added to protect buyers when markets were weak. The tiers were dropped at the end of 2024. A year later Solanium ran its first HyperEVM sale.

The site's terms name Solanium Limited as the company that runs the service. The docs and website we read do not name the founders.
