GrowThePie
Track TVL, transaction count, revenue, and profit for any Ethereum L2 directly from your iPhone home screen.
Monitor Any Ethereum L2 in Real Time
GrowThePie aggregates on-chain data across Ethereum's Layer 2 ecosystem, and this integration brings those numbers to your iOS home screen. Select a chain, add a widget, and see live metrics without opening a browser or navigating dashboards. The Chain module supports any available L2 and surfaces twelve distinct metrics covering both activity and chain economics.
Twelve Metrics Covering Activity and Economics
The metrics split into two useful categories. Activity metrics, including daily transaction count, active wallets, and throughput in transactions per second, show whether a chain is being used. Economic metrics, including TVL, user revenue, rent paid to L1, onchain profit, stablecoin market cap, FDV, and market cap, show whether it is financially sustainable.
Rent paid to L1 for data availability and onchain profit (fees minus rent) are particularly useful for comparing rollup economics. A chain with high revenue but higher rent costs may be less profitable than one with lower fees but more efficient data availability usage. App revenue adds a third lens, showing how much value applications deployed on the chain are generating independently of base layer fees.
Thirty Days of Historical Context
Every metric includes a chart backed by 30 days of indexed history, so you can see direction rather than just a point-in-time number. Whether TVL is recovering after a drawdown or transaction costs are falling as the chain scales, the chart surfaces the trend. Data is indexed on a schedule, keeping battery and mobile data usage low while keeping your widgets current.

Who uses this
- DeFi researchers
GrowThePie exposes the economic layer of each rollup, including revenue, rent paid to L1, and onchain profit. Researchers comparing chain sustainability can glance at profit margins from the home screen rather than cross-referencing multiple dashboards mid-analysis.
- L2 investors
Token-level metrics, including FDV and market cap, sit alongside on-chain activity data like daily active wallets and transaction count. Investors can watch whether token valuations are tracking real usage or diverging, without opening a browser each time.
- Protocol teams
Teams building on or competing with specific L2s can track throughput, app revenue, and stablecoin market cap for any chain. A widget per chain makes it easy to spot shifts in competitor activity before they surface in weekly reports.
- Crypto traders
Transaction costs and TVL signal whether a chain is getting expensive or losing liquidity. Traders deploying capital across L2s can check median transaction costs and current TVL from the home screen before committing to a bridge.
FAQs
Which L2 chains can I track with GrowThePie in PulseKit?
The integration supports any chain available in GrowThePie's dataset, selected via a dropdown when configuring the Chain module. GrowThePie covers the major Ethereum L2s including Arbitrum, Optimism, Base, zkSync, and Starknet, among others. Select the chain once during setup and all twelve metrics populate automatically.
How often does GrowThePie data update in PulseKit?
GrowThePie data in PulseKit is indexed, meaning it refreshes on a scheduled basis rather than being pulled live on demand. This keeps battery and mobile data usage low. On-chain metrics like transaction count and TVL typically reflect the most recently indexed daily snapshot from GrowThePie.
What does 'rent paid' mean in the GrowThePie metrics?
Rent paid is the fee an L2 pays to Ethereum's base layer for data availability, covering the cost of posting transaction data to L1 so it can be verified. Subtracting rent paid from user revenue gives onchain profit, which shows how much a chain retains after covering its L1 costs. Chains with high throughput and efficient DA usage tend to show better profit margins.
Can I track multiple L2 chains at once in PulseKit?
Yes. You can add multiple Chain module widgets, each configured to a different L2. Each widget displays the twelve available metrics for its selected chain independently. Use separate home screen widgets or stack them in the Today View to compare chains side by side without switching apps.
What is onchain profit in GrowThePie?
Onchain profit is the difference between fees collected from users (revenue) and the rent paid to L1 for data availability. A positive and growing profit figure indicates the chain is covering its operational costs and retaining value. A negative figure means the chain is currently subsidizing activity or its DA costs exceed what it collects in fees.
Does the GrowThePie integration show historical chart data?
Every metric includes a chart with up to 30 days of historical data. The charts let you assess trends, such as whether TVL is rising after a drawdown or transaction costs are declining as the chain scales, rather than relying on a single current value. Historical data is retained for 30 days per the integration's storage policy.
What is app revenue and how is it different from chain revenue?
App revenue is income generated by applications deployed on the chain, such as DEXs, lending protocols, and other dApps. Chain revenue (labeled Revenue) represents fees paid by users directly to the chain itself. Tracking both together shows whether an ecosystem is generating economic activity beyond basic transaction fees, which can indicate a more durable and composable network.
