The following review will look at Calyx, the next-generation cross-chain launchpad that wants to make token sales simple, transparent, and accessible across multiple blockchains. We will give a step-by-step on how it works for both participants and founders, as well as look at the fees, safety measures, and its pros and cons.  

What is Calyx?

Calyx is a cross-chain token launchpad powered by NEAR Intents, a system that routes and settles transactions between different blockchains automatically. The platform connects participants and founders within a single ecosystem, enabling token sales that span multiple blockchains in a one transaction. 

For participants, Calyx offers one-click access to curated token sales using assets from any supported blockchain. 

For founders, it provides professional-grade launch infrastructure, including multi-chain fundraising, vesting, compliance tools, and optional liquidity management.

The platform’s key capabilities include:

• Any chain, any token, one transaction: Users can contribute instantly with the assets they already hold, while Calyx handles all bridging and conversion in the background;
• Multi-chain token support: Through OmniBridge, projects can distribute tokens across ecosystems without extra redeployments; 
• Compliance: Founders must complete KYB verification and KYT checks are performed automatically per wallet. KYC for users is optional. 

Calyx currently supports fixed-price and price discovery (pro-rata) sale formats, with more advanced mechanisms like bonding curves planned for the roadmap.

There are no upfront costs at launch, though individual sales may include frontend or performance-based fees disclosed in advance.

How to participate in token sales on Calyx: Step-by-step

Calyx is built to make joining token launches simple, transparent, and accessible from various blockchains. So, instead of manually bridging, swapping, or dealing with incompatible tokens, on Calyx, users can contribute directly from over 20 supported blockchains using the assets they already hold.

This entire process runs through NEAR Intents, which routes payments across chains automatically in the background. Users can see the estimated amount and fees before confirming, and as soon as the route settles, their allocation will appear on the sale page.

Here’s the step-by-step process for participants:

1. Connect your wallet or passkey: Choose from one of the supported wallets use a passkey that has enough funds for your purchase;
2. Choose the project sale page: Select the token sale you want to join from the official listings on Calyx. Each sale page clearly shows project details, tokenomics, vesting terms, and eligibility requirements (like KYC or regional restrictions);
3. Pick your payment asset and chain: You can join from any supported blockchain using the asset of your choice. For example, contributing USDC from Polygon or ETH from Arbitrum. Calyx routes everything cross-chain automatically in the background;
4. Enter the amount and review fees: The interface shows all applicable network and project fees before you confirm. If a fee isn’t listed, it isn’t charged;
5. Confirm and wait for settlement: Transactions usually settle within seconds to a few minutes, depending on the source chain. While it’s pending, the interface shows your route status and a transaction ID;
6. View your allocation: Once confirmed, your purchase appears under My Purchases, along with your vesting and claim schedule.

Sale Types

Calyx supports two main sales formats that determine how allocations are distributed:

• Fixed price sale, in which tokens are sold at a set price until the supply runs out or the time window closes. For example, let’s imagine a project that sells 10 million tokens at $0.01 each for two weeks. In this case, the sale ends when the tokens or time runs out;
• Price discovery (pro-rata) sale, in which participants deposit during a sale window, and final allocations are calculated at close based on total deposits. In this example, if 10 million tokens are offered and $250,000 is deposited, the final price is $0.025, and tokens are distributed proportionally.

Claiming and trading tokens 

Once you’ve joined a sale, your contribution is locked until the sale closes. You’ll then receive your token allocation according to the project’s vesting schedule, which appears under Your Allocation on the project page.

Calyx supports flexible vesting, that is projects can set a cliff period (no tokens released until a certain date) followed by linear unlocks, meaning tokens gradually release over time instead of all at once.

Here’s how to claim:

1. Go to My Participations and connect your wallet;
2. Open the project page and click Claim Now;
3. Approve the claim transaction in your wallet and wait for confirmation;
4. Tokens are credited to your Calyx Balance, which you can withdraw to any supported chain.

Once unlocked, tokens can also be traded instantly through Calyx’s cross-chain trading widget, powered by NEAR Intents. You can swap tokens directly between chains or keep them in your Calyx balance for lower fees.

How to launch a token on Calyx: Step-by-step

Calyx provides founders with an end-to-end launch infrastructure that removes much of the technical and logistical friction of going to market. Projects gain cross-chain reach, automatic token distribution, and built-in liquidity options, all powered by NEAR Intents and OmniBridge.

Instead of building your own launch platform, Calyx lets you manage fundraising, compliance, and post-sale liquidity through one interface, while participants can join with the tokens they already hold from more than 20 blockchains.

Here’s how the process works:

Before the sale

Founders start by completing KYB verification, a requirement for all projects. Once verified, you configure your sale settings, including:

• Choosing a sale type (fixed price or price discovery);
• Defining caps, timelines, and vesting terms (typically a cliff followed by linear unlocks);
• Preparing your token and tokenomics, ensuring the asset is available or bridged to NEAR, since all sales and claims are processed there;
• Uploading key launch materials such as whitepapers, tokenomics tables, and GTM plans.
  

During the sale

Once the sale goes live, contributors can participate from any supported blockchain using the assets they already hold — no manual bridging or swapping needed.

• NEAR Intents automatically routes and settles payments across chains.
• Each project’s sale page lists the price, caps, vesting schedule, and risk disclosures.
  
• Founders can monitor real-time contributions, transaction status, and remaining caps directly from the Calyx console.

After the sale

When the sale ends:

• Tokens are distributed automatically according to the project’s vesting schedule, viewable on the sale page;
• Founders can allocate a portion of the raise to seed liquidity pools, making the token tradable via NEAR Intents;
• The Calyx team continues to support post-sale efforts, such as credibility signals, milestone updates, and marketing amplification.

Calyx Fees

Calyx is designed with transparent, success-based fees for founders and minimal, clearly disclosed costs for participants. Every charge is displayed before confirmation, so users and projects know exactly what they’re paying for.

Participant fees

Participants see all applicable fees directly in the sale interface before confirming a transaction. These include:

• Network fees: Vary by chain and route; Calyx automatically calculates and displays them during checkout;
• Platform or project fees: A project can apply its own fee, which will appear in the summary before confirmation. 

If a fee isn’t shown in the UI, you won’t be charged.

Transactions that fail or time out return funds to the participant’s wallet, and successful routes are recorded on-chain. 

Founder fees

Calyx follows a success-based fee model, meaning projects only pay if their raise succeeds.

• No upfront cost: Listing and setup are free;
• Success fee: A small percentage of the total raise and/or token allocation, agreed before launch;
• No minimum-raise penalty: If the soft cap isn’t met, there’s no fee;
• Full transparency: Final terms are confirmed with the Calyx team before launch, with no hidden or retroactive charges.

Is Calyx safe? 

In October 2025, AuditOne, a blockchain security firm, conducted an audit of Calyx’s smart contracts. The review evaluated security, code quality, and documentation standards, yielding high performance across all three categories, specifically:

• 98% in security;
• 95% in code quality and; 
• 94% in documentation quality. 

All high-severity issues found during the audit were fully resolved, and the report confirmed that no critical vulnerabilities remained. AuditOne highlighted Calyx’s strong access control structure, accurate fund-handling logic, and robust vesting configuration checks.

Additionally, the platform includes built-in checks to verify project legitimacy and maintain transaction integrity across every sale:

• KYB (Know Your Business): Mandatory for all project teams before listing, ensuring legitimate and verifiable entities.
• KYC (Know Your Customer): Optional and project-configurable, depending on the sale’s requirements or regional restrictions.
• KYT (Know Your Transaction): Continuous monitoring applied to all transactions for suspicious activity or sanctions compliance.
• Regional filters: Founders can set geographic restrictions when needed to comply with local laws.

Calyx never holds user funds directly. All transactions occur on-chain through NEAR smart contracts. Participants always interact via verified sale pages, with visible token addresses and on-chain receipts. Vesting schedules and unlocks are publicly viewable, reducing the risk of hidden token releases or insider manipulation.

Finally, the platform provides clear disclaimers, sale-specific risk summaries, and built-in verification steps to prevent phishing or manual transfer errors. It also includes project due diligence, requiring every listed sale to present documentation on team identity, tokenomics, audits, and vesting terms before going live.
