They're the baseline you compare individual vaults against, and the input you'd hand to an agent making a "should I rotate?" decision. ## What's benchmarked A benchmark represents the TVL-weighted average APY across the five largest vaults in a given denomination and network, each with at least $1M in TVL. Vaults.fyi publishes separate **USD** and **ETH** benchmarks for Ethereum mainnet and every supported L2: - **USD benchmark:** a weighted-average yield across the largest stablecoin yield markets on a given network. - **ETH benchmark:** the equivalent for ETH yield, spanning the largest LSTs and lending markets. - Both are computed daily, with 1-day, 7-day, and 30-day rolling averages Fine more detail on our methodology [here](https://docs.vaults.fyi/methodology/benchmark-rates?ref=blog.vaults.fyi). Coverage spans Ethereum mainnet, Base, Arbitrum, Optimism, Polygon, and other [supported networks](https://docs.vaults.fyi/concepts/supported-protocols?ref=blog.vaults.fyi#supported-networks). ## Where to get benchmark data - If you just want to see benchmark rates, the analytics page at [app.vaults.fyi/analytics](https://app.vaults.fyi/analytics?ref=blog.vaults.fyi) has them charted out for every supported network. - If you want to do further analysis, build benchmark rates into your own product, or feed them into an agent, the API and MCP server expose the same data programmatically. Here's how to pull them. ### Using the API Let's run through an example, showing how to get USD benchmark data on Ethereum (mainnet). First, we can get the current benchmark values: ```bash curl -H "x-api-key: $VAULTS_API_KEY" \ "https://api.vaults.fyi/v2/benchmarks/mainnet?code=usd" ``` Response: ```json { "apy": { "1day": { "base": 0.0346, "reward": 0, "total": 0.0346 }, "7day": { "base": 0.0354, "reward": 0, "total": 0.0354 }, "30day": { "base": 0.0396, "reward": 0, "total": 0.0396 } }, "timestamp": 1778198400 } ``` If we want to show historical rates, we can get benchmarks with a date range: ```bash curl -H "x-api-key: $VAULTS_API_KEY" \ "https://api.vaults.fyi/v2/historical-benchmarks/mainnet?code=usd&fromTimestamp=1771142400&toTimestamp=1778630400&perPage=500" ``` Example: Get USD benchmark rates on mainnet ![USD 30-day benchmark APY, last 90 days, mainnet vs base](https://storage.ghost.io/c/80/1e/801e59ba-aea3-41d2-aff6-47dda0ee853e/content/images/2026/05/usd-benchmark-90d.png) USD benchmark, 30-day APY, mainnet vs base, last 90 days. One curl call and ten lines of matplotlib. The response is a `data` array of the same per-day shape. Use `fromTimestamp` and `toTimestamp` (Unix seconds) to scope the window; `perPage` goes up to 500. Swap `mainnet` for `base`, `arbitrum`, `optimism`, etc. to get other networks. Swap **`usd`** for **`eth`** to get the ETH benchmark. ## Using the MCP server If you'd rather query benchmarks from a chat interface (Claude Desktop, Cursor, your own agent), the same data is available via vaults.fyi's MCP server. We do one quick configuration, then ask in natural language. Follow the our quickstart guide, outlined below.

Try "Pull 30d ETH benchmark rates for Arbitrum, covering the last 180 days." The MCP returns the same `apy.{1day, 7day, 30day}` structure as the API, so agents can read it directly without any field translation. ## What to do with it A few practical applications: - **Rebalance threshold:** only move funds when your candidate vault beats the network benchmark by N basis points (after gas) - **Honest performance tracking:** "up 4.0% APY" is meaningless if the benchmark is 4.0%. Track your portfolio's effective yield against the benchmark and surface underperformance. - **Agent decision input:** pass the current and 30-day benchmark into a yield-rotation agent's context so it has a sense of what counts as "above average" today - **Strategy backtesting:** combine `historical-benchmarks` with `vault_apy_history` to compute alpha vs. the benchmark for a given vault over time Have fun building.
