One-Click Crypto Investing: How Embedded Wallets Make Indices Accessible
Token Metrics Team • October 2025 • ~5 min read
The Onboarding Problem in Crypto
You want to invest in a crypto index. But first, you need to:
Choose a wallet (MetaMask? Phantom? Ledger?)
Fund the wallet (buy crypto on an exchange, withdraw to the wallet)
Navigate gas fees (which chain? What's a reasonable gwei?)
Approve smart contracts (what does "unlimited allowance" mean?)
Execute the purchase (slippage settings? minimum received?)
By step 3, half of new users have given up. By step 5, even experienced users are annoyed. The friction isn't the investment decision—it's the operational complexity.
What is an Embedded Wallet?
An embedded wallet is a self-custodial wallet built directly into the platform. You don't download a browser extension or manage a separate app. You interact with the wallet through the same interface where you view indices and make purchases.
Key features:
Self-custodial: You control the keys, not the platform.
Seamless: No switching between apps or browser tabs.
Smart routing: The wallet optimizes gas, selects chains, and handles approvals automatically.
Transparent: You see fees, slippage, and expected value before confirming.
Think of it as the difference between booking a flight through 10 separate websites (airline, payment processor, insurance) vs. one integrated platform that handles everything.
How TM Global 100 Uses Embedded Wallets
First-time setup (30 seconds):
Click "Buy Index"
Create or connect a wallet
Secure your recovery phrase
Every purchase after (90 seconds):
Click "Buy Index"
Review holdings, fees, and slippage
Confirm
The wallet handles:
Chain selection (Ethereum, Polygon, Arbitrum, etc.)
Gas estimation and optimization
Token swaps if you're funding with non-USDC assets
Smart contract approvals
You see:
Estimated gas cost
Platform fee
Maximum slippage
Minimum expected tokens
You confirm once. The wallet does the rest.
Why This Matters for Index Adoption
Indices should be simple. You're delegating complexity—picking 100 tokens, rebalancing weekly, switching regimes—to an automated system. The purchase experience should match that simplicity.
Traditional crypto index flow:
Research index (10 minutes)
Set up wallet (15 minutes)
Buy crypto on exchange (20 minutes)
Transfer to wallet (10 minutes, plus anxiety about losing funds)
Approve contracts (5 minutes of confusion)
Execute purchase (5 minutes)
Total time: 65 minutes, most of it friction.
TM Global 100 with embedded wallet:
Research index (10 minutes)
Buy index (90 seconds)
Total time: 12 minutes, mostly learning.
Funding Options
The embedded wallet supports multiple funding paths, depending on your chain and wallet setup:
USDC (most common): If you have USDC on a supported chain, the purchase is direct.
Other crypto: The wallet can swap your existing crypto (ETH, BTC-wrapped, USDT, etc.) to the required assets before buying the index.
Fiat (chain-dependent): Some chains and regions support fiat on-ramps directly in the wallet.
All options appear at checkout based on what's available for your wallet and location.
Security: Self-Custodial Doesn't Mean Risky
Embedded wallets get confused with custodial wallets, but they're fundamentally different:
Custodial wallet: Platform holds your keys. You trust them not to lose funds, get hacked, or freeze your account.
Embedded self-custodial wallet: You hold the keys. The platform provides the interface, but you own the assets. If the platform vanishes, your funds remain in your wallet.
What you're responsible for:
Securing your recovery phrase (write it down, store it safely)
Signing transactions (every purchase/sale requires your approval)
Understanding that lost recovery phrases = lost funds
What Token Metrics cannot do:
Access your funds without your signature
Recover your wallet if you lose your recovery phrase
Freeze or restrict your withdrawals
Who Benefits from Embedded Wallets?
New crypto users: You want exposure without learning the entire Web3 stack first.
Time-constrained investors: You don't want to spend an hour on operational setup.
Multi-account holders: You prefer keeping index holdings separate from your main trading wallet.
Mobile-first users: Embedded wallets work seamlessly on mobile, unlike some browser-extension wallets.
What Happens After Purchase?
Your index position appears under My Indices with:
Real-time value and P&L
Holdings breakdown (treemap + table)
Transactions history (every rebalance and regime switch)
When you want to sell, the flow is identical: click "Sell Index," review details, confirm. Funds go directly to your embedded wallet, and you can move them wherever you want.
