Intent vs Non‑Intent Bridges: L2 Market Context and Liquidity (Arbitrum, Base, Optimism)

Public

Build a thesis-support dashboard with daily (UTC) metrics for Arbitrum, Base, and Optimism over the last 180 and 365 days. Provide PNG charts (300 dpi) and CSV downloads for every widget. No private timestamps. Include: 1) L2 Market Context (per chain) TVL (USD) DEX spot volume (USD) Fees and revenue (USD) Transactions and active addresses (counts) Median/average gas price (Gwei) if available Format: daily lines; clean labels; consistent colors per chain. CSV columns: date, chain, metric, value. 2) USDC Liquidity Context (per chain) USDC circulating supply (USD or units) USDC netflows (mint/burn or cross-chain net) DEX liquidity for USDC pairs (e.g., Uniswap/Curve): top pools TVL (USD) and, if possible, depth around ±50 bps Optional: USDC peg deviation (% from $1) Format: daily lines/bars; CSV as above. 3) Bridge Activity (by protocol and chain pair) Daily bridge volume (USD) by protocol: Across, Squid/Axelar, Circle CCTP, Stargate/LayerZero (or closest mappings). Stacked area (total) + individual lines. Inbound/outbound bridge volume (USD) by chain pair (Arbitrum↔Base, Arbitrum↔Optimism, Base↔Optimism). Heatmap + CSV if available. 4) Comparative Insights Correlation heatmaps per chain (TVL, DEX volume, fees, transactions, active addresses, USDC supply, USDC DEX liquidity). PNG + matrix CSV. Scatter plots (PNG + joined CSV): Fees (x) vs DEX volume (y), colored by chain USDC supply (x) vs DEX volume (y), colored by chain USDC DEX liquidity (x) vs DEX volume (y), colored by chain Weekly aggregates for all above to match weekly TVL visuals. Quality and deliverables Alignment: daily date index across all metrics; NA for missing; no forward fill Units: USD or Gwei labeled in axes and CSV headers Data dictionary: data_dictionary.csv (metric, units, definition, DeFiLlama source) Notes: notes.md explaining bps (0.01%; 100 bps = 1%) and that “spread” in the thesis refers to execution-layer pricing/fees/slippage, distinct from gas/native fees Tags

L2 Comparative Thesis Dashboard: Arbitrum, Base, and Optimism

This dashboard provides a comprehensive, daily-granularity analysis of key metrics for Arbitrum, Base, and Optimism over the last 365 days. It aims to support a thesis by examining L2 market context, USDC liquidity, and bridge activity. All charts are configured for daily data, and where possible, metrics are compared across the specified chains/protocols.

Note on Deliverables: The request for PNG charts, CSV downloads, specific CSV column formats, data dictionaries, and notes.md are frontend rendering and export features, which are not part of this JSON configuration. This JSON defines the data and chart types; the DefiLlama frontend will handle the visualization and export capabilities.

1. L2 Market Context

This section provides an overview of the core economic and activity metrics for Arbitrum, Base, and Optimism.

Note on Optimism DEX Volume: Optimism's chain-level DEX volume metric is not available in the provided entity list. The optimism-bridge protocol's volume metric is also not available. Therefore, it is excluded from this comparison.

Note on Optimism Fees & Revenue: Optimism's chain-level fees and revenue metrics are not available in the provided entity list. The optimism-bridge protocol's fees and revenue metrics are also not available. Therefore, it is excluded from this comparison.

Note on Gas Price and Optimism Metrics: Median/average gas price is not a directly available chart type in the current schema. Additionally, Optimism's chain-level transaction and active address metrics are not available in the provided entity list. The optimism-bridge protocol also does not have these metrics. Therefore, these metrics are excluded from this comparison.

2. USDC Liquidity Context

This section examines the circulating supply and liquidity dynamics of USDC across Arbitrum, Base, and relevant DEXs.

Note on Optimism USDC Supply: Optimism's chain-level stablecoin supply metric is not available in the provided entity list. The optimism-bridge protocol's stablecoin supply metric is also not available. Therefore, it is excluded from this comparison.

Note on Optimism USDC Netflows: Optimism's chain-level stablecoin inflow metric is not available in the provided entity list. The optimism-bridge protocol's stablecoin inflow metric is also not available. Therefore, it is excluded from this comparison.

Note on USDC Peg Deviation and Liquidity Depth: The current dashboard schema does not support direct charting of USDC peg deviation (% from $1) or liquidity depth around specific basis points (e.g., ±50 bps). These advanced metrics would require custom data processing and visualization beyond the scope of this builder.

3. Bridge Activity

This section analyzes the daily bridge volume by key protocols facilitating transfers to and from Arbitrum, Base, and Optimism.

Note on Bridge Protocols: Bridge volume metrics for Circle CCTP and Squid/Axelar are not directly available as chart types in the provided entity list. Stargate's primary available metric is TVL, which is used as a proxy for its activity in this context. Across's volume metric is used. For optimism-bridge, TVL is used as the available metric. The request for stacked area (total) + individual lines is handled by the multi-chart configuration.

Note on Inbound/Outbound Bridge Volume by Chain Pair (Heatmap): The current dashboard schema does not support direct visualization of inbound/outbound bridge volume by specific chain pairs (e.g., Arbitrum↔Base) as a heatmap or individual lines. This would require custom data aggregation and a specialized chart type beyond the scope of this builder.

4. Comparative Insights

This section addresses the request for comparative analysis, noting current visualization limitations within the dashboard builder.

Note on Correlation Heatmaps and Scatter Plots: The current dashboard schema does not support the generation of correlation heatmaps or scatter plots directly. These advanced analytical visualizations require specific statistical processing and chart types that are not available. However, the raw data for all metrics presented in this dashboard can be exported via CSV (a frontend feature) and used in external tools (e.g., Python, R, Excel) to perform such comparative analyses.

Weekly Aggregates: While the primary request was for daily, all charts can be re-configured to 'weekly' grouping if desired for a broader trend view, matching weekly TVL visuals.
