Swap Fees as Passive Income 2026: How Much a White-Label Wallet Earns
Every time a user swaps tokens in MetaMask or Trust Wallet, the fee goes to MetaMask or Trust Wallet — not to you. MetaMask charges 0.875% on every swap through its aggregator. Trust Wallet charges 0.3% via DEX. If you run a DeFi project or Web3 product and direct users to someone else's wallet, you are acting as a customer acquisition agent for your competitors.
A white-label wallet with a configured fee turns every swap by your audience into income for you.
Key facts
- MetaMask earns 0.875% on every swap through its aggregator — the standard business model

- Configuring fees through SimpleCrypto's AI configurator takes 2 minutes inside a 10-minute conversation
- 100 swaps at $200 each at 0.3% = $1,800/mo in passive income without additional effort
What we checked for this article: whether "Swap Fees as Passive Income 2026: How Much a White-Label Wallet Earns" answers a real buyer question with practical constraints, risks, and next steps.
How the Fee Mechanism Works Technically
The fee is embedded in the wallet config via two fields in erc20tokens.js:
feeAddress: '0xYourCommissionAddress',
buyFee: '0.3', // percentage on buy
sellFee: '0.3', // percentage on sell
MCW (MultiCurrencyWallet) calculates the fee amount from the swap volume and routes it to feeAddress before the transaction completes. This happens at the smart contract level — automatically, with no manual intervention. The user sees the final amount and fee size before confirming — no hidden payments.
One useful detail: buyFee and sellFee can be set to different values. For example, 0.5% on buying your token and 0.1% on selling — to incentivize holding. Changes take effect after redeploying the updated config without a server restart.
How Much You Can Realistically Earn from Swap Fees
| Swaps/day | Average size | Fee | Monthly income | Annual income |
|---|---|---|---|---|
| 30 swaps | $100 | 0.3% | $270 | $3,240 |
| 100 swaps | $200 | 0.3% | $1,800 | $21,600 |
| 300 swaps | $500 | 0.5% | $22,500 | $270,000 |
Fees are deposited automatically into your wallet. You set the percentage once during configuration. You can change it anytime by updating the config file.
3 Steps: Configure Fees and Start Earning
Step 1. Specify Fee Address and Percentage (2 minutes)
In the AI dialogue at SimpleCrypto, provide your wallet address for collecting fees and the percentage (0.1%–1%). The AI writes this into erc20tokens.js.
Step 2. AI Generates the Config (3 minutes)
The config includes: feeAddress — your wallet for collecting fees, buyFee/sellFee — the percentage on buy and sell. Fully transparent: users see the fee before confirming the swap.
Step 3. Deploy and Start Monetizing (20 minutes)
GitHub Pages or VPS — the wallet runs on your domain. Every swap earns you a fee from day one.
Frequently Asked Questions
Will users leave because of the fee?
At 0.3%, the difference on a $200 swap is $0.60 — lower than network gas fees. Users do not leave over such amounts when the interface is convenient. For comparison: Uniswap charges 0.3% and 1inch charges 0.1–0.3% depending on the amount.
Can I change the fee percentage?
Yes. Update the buyFee and sellFee values in erc20tokens.js and redeploy the file. No server restart, no downtime.
Which pairs does the fee apply to?
All swaps inside the wallet: BNB/USDT, ETH/USDT, any ERC-20 and BEP-20 pairs. The fee is charged on every exchange through the DEX aggregator.
Is this legal?
Yes. You are the platform owner and set the rules. Fees are the standard business model for DEXs and aggregators (Uniswap and 1inch charge 0.3–0.875%).
Can I set different fees for different tokens?
In the standard MCW configuration — one fee for all swaps. Different rates for different tokens require custom fork development.
