How to Create Your First Onchain Basket

We have watched hundreds of baskets get created on the platform. Some attract holders within days. Others sit empty. The difference usually comes down to a few decisions made before the deploy button gets clicked.

This is how we would build a simple thematic basket today, walking through the same interface you will use, and calling out the decisions that actually matter. If you have built a traditional ETF before (or tried to), the contrast will be obvious. If you haven't, that is sort of the point.

One thing to know upfront: on Ethereum, every BSKT must currently include an allocation to the ALVA token as part of its composition. This requirement is expected to change with the Base deployment, but for now, factor it into your allocation planning.

What Is an Onchain Basket?

An onchain basket is a basket token (BSKT) built on the ERC-7621 standard that bundles multiple ERC-20 tokens into a basket where investors receive ERC-20 LP shares representing their proportional stake. ERC-7621 extends ERC-721 (the NFT standard), meaning each BSKT is a unique, non-fungible token that holds a portfolio of ERC-20 assets inside it. It works similarly to a traditional ETF: investors get diversified exposure through one asset, and the underlying holdings are transparent and verifiable.

The key differences are what make it interesting. BSKTs are fully decentralized, meaning no custodian holds the underlying assets on your behalf. They are permissionless, so anyone can create one or invest in one. And as ERC-7621 tokens, they are composable with the rest of DeFi, so your basket token can be traded on DEXs, used as collateral, or integrated into other protocols.

Before You Start

You need three things:

• An Ethereum wallet. MetaMask, Rabby, or any wallet that supports Ethereum. Make sure it is connected to the right network.
• Some ETH for gas. Deploying a basket is an onchain transaction, so you will need ETH to cover gas fees.
• A clear strategy. Know which tokens you want to include and why. The best baskets have a coherent thesis, not just a random collection of tokens. The app's creation interface makes it easy to get started, but having a plan before you open it makes the process much smoother.

Step 1: Choose Your Assets

Start by deciding which tokens belong in your basket. The best approach is to pick a theme and stick with it. Some examples:

• DeFi blue chips: AAVE, UNI, MKR, LINK
• AI tokens: FET, RNDR, OCEAN, AGIX
• Layer 2 ecosystem: OP, ARB, MATIC, METIS
• Stablecoin yield: A basket of yield-bearing stablecoins

When choosing assets, consider diversification (don't put everything in one sub-sector), liquidity (tokens with thin trading volume will make your basket harder to mint and redeem), and correlation (assets that all move in lockstep don't provide much diversification benefit).

For this walkthrough, we will build a "DeFi Core" basket containing AAVE, UNI, MKR, and LINK. This is a real allocation we have seen work well on the platform, not a hypothetical.

Step 2: Set Your Weights

Next, decide how much of each token should make up your basket. Weights are expressed as percentages and must add up to 100%. There are a few common approaches:

• Equal weight: Give every asset the same allocation. Simple and avoids concentration risk. For four assets, that's 25% each.
• Market-cap weighted: Allocate more to larger assets. This mirrors how most traditional index funds work.
• Conviction weighted: Put more weight on the assets you're most bullish on. Higher potential returns, but more concentrated risk.

For our DeFi Core basket, we will go with a conviction-weighted approach:

• AAVE: 35% - largest lending protocol by TVL, consistent fee revenue
• LINK: 30% - oracle infrastructure, hard to replace
• UNI: 20% - dominant DEX, but governance token value is less clear
• MKR: 15% - proven track record, but smaller position because of its higher token price and concentrated governance

Notice we are not equally weighting everything. The reasoning behind each weight matters more than the exact number. Holders want to see that you have a thesis, not just a coin flip. You can always rebalance later if your view changes.

Step 3: Configure Your Basket

Now give your basket an identity. You'll need to set a few things:

• Name: Something descriptive that tells potential holders what the basket is about. Example: "DeFi Core Index"
• Ticker symbol: A short symbol, like a stock ticker. Example: "DEFI4"
• Description: A brief explanation of your strategy and what the basket aims to achieve.
• Management fee: The annual fee you'll charge holders, expressed as a percentage. This is how you earn revenue as a basket creator.

On management fees: keep them competitive. High fees discourage holders and make your basket less attractive compared to alternatives. Look at what similar products charge and price accordingly. A fee between 1-3% annually is a reasonable starting range for most strategies.

Step 4: Deploy

With everything configured, it's time to go live.

1. Go to bskt.alvara.xyz and connect your wallet.
2. Navigate to the basket creation interface.
3. Enter your assets, weights, name, ticker, description, and fee.
4. Review everything carefully. Once deployed, fees and core parameters are permanent and cannot be changed.
5. Submit the transaction and confirm it in your wallet.
6. Pay the gas fee and wait for the transaction to be confirmed onchain.

Your basket token is now live on Ethereum. It has its own contract address, and anyone can view the composition, mint new units, or redeem existing ones. It appears on the Explore page and the manager leaderboard, where potential investors can discover it. You will also receive a management NFT that grants you rebalancing control over the basket. Note that a creation fee (a percentage of the initial deposit defined by the protocol) applies when deploying.

Step 5: Share and Grow

A basket with no holders does not earn fees. Once your BSKT is deployed, you need to get it in front of people.

Build credibility through performance and consistent management. Your track record is fully onchain and verifiable, so every rebalance, every fee structure, and every allocation decision is visible to potential holders. Over time, a well-managed basket with transparent history speaks louder than any badge.

Your basket automatically appears on the manager leaderboard, ranked by performance, holder count, and total value locked. The leaderboard is the primary discovery mechanism on the platform, so how your basket performs in the first few weeks matters.

When someone mints your basket, they deposit ETH and the protocol automatically converts it into the basket's constituent tokens according to your allocation weights. They receive LP tokens in return. All deposits include automatic MEV protection. The more holders you attract, the more management fees accrue to you.

Some practical tips for growing your basket:

• Build in public. Share your reasoning when you make changes. Write about your strategy on X.
• Track performance. Monitor your basket's performance using the platform and share updates with your community.
• Be consistent. The best fund managers have a clear strategy. Do not chase trends with every rebalance.

Managing Your Basket Over Time

Creating the basket is just the beginning. Good portfolio management is an ongoing process.

You can rebalance your basket's weights as market conditions change. If one asset has outperformed and now represents a larger share of the basket than intended, adjust the weights to bring it back in line. If your thesis on a particular token changes, update the allocation accordingly.

Management fees accrue automatically based on the total value held in your basket. You do not need to manually collect anything. The protocol handles fee accounting onchain.

Monitor your basket's performance regularly. Pay attention to how the underlying assets are doing individually and as a group. A well-managed basket that adapts to changing conditions will attract and retain more holders than one that gets deployed and forgotten.

Mistakes First-Time Creators Make

We have seen enough baskets launched on the platform to spot the patterns. Here is what trips people up:

• Too many tokens. Fifteen assets in a basket is not diversification, it is dilution. Each token should be there for a specific reason. If you cannot explain why it is in the basket in one sentence, cut it.
• Setting fees too high. A 5% management fee on a basket with no track record will not attract holders. Start competitive — 1-2% is a reasonable range. Holders can see the fee before they mint, and they will compare yours to every other basket on the leaderboard.
• Weak descriptions. Not including enough context in the basket description is a missed opportunity. Potential holders want to understand your thesis, your reasoning for each allocation, and how you plan to manage the basket. A vague description loses investors before they even look at the numbers.
• No thesis. "I like these coins" is not a strategy. The description field exists for a reason. Explain what the basket captures and why these specific weights. Holders read this.
• Ignoring liquidity. Including a token with $50K daily volume in your basket means minting and redeeming will be expensive due to slippage. Check the liquidity of every token before you add it.
