defipipe 0.1.1

Per-block, point-in-time DeFi contract state as pandas DataFrames: Aave rates, Uniswap prices, Lido supply, aligned onto one time axis.

defipipe: per-block DeFi state as pandas DataFrames

What read functions actually returned at every Ethereum block: Aave borrow rates, Uniswap slot0 prices, Lido total staked ETH. Reconstructed historically, indexed live, and aligned onto one clean time axis.

Most DeFi data is built from events. defipipe serves state: the result of calling a contract's read functions at a specific block. If you need to know what the Aave WETH borrow rate actually was at block 19,000,000, not an hourly average from a dashboard, this is the API for it.

Install

pip install defipipe

Five lines to an aligned DataFrame

from defipipe import Client

df = Client().aligned([
    "eth:aave:v3:0x87870bca3f3fd6335c3f4ce8392d69350b4fa4e2/weth:call:getreservedata[currentvariableborrowrate]",

No API key needed for recent data at hourly bars. Full history and per-block granularity: get a key at https://defipipe.io/pricing and set DEFIPIPE_API_KEY (or pass api_key=).

Why quants use this

• Point-in-time correctness. Every value is the last observation at or before each interval boundary, resolved through the block↔timestamp map. No interpolation, no lookahead bias: safe for backtests.
• Exact raw values. client.series(id) returns value_raw as the exact on-chain string (uint256-safe) alongside the unit-scaled float.
• One key for everything. Canonical series IDs ({chain}:{protocol}:{version}:{instance}[/{scope}]:{kind}:{metric}) name every series across protocols; browse them at https://defipipe.io/datasets.
• Per-block granularity back to each pool's deployment, from our own archive node, not sampled snapshots.

Raw per-block rows

raw = Client(api_key="dp_...").series(
    "eth:uniswap:v3:0x88e6a0c2ddd26feeb64f039a2c41296fcb3f5640:call:slot0[sqrtpricex96]",
    since="2026-06-01",
)
raw.head()  # block_number → ts, value_raw, value
