Whose work this is built on

Plumb is a thin thing resting on other people's heavy things. Here is all of it.

The contracts

Plumb deploys nothing. Every address it touches belongs to somebody else and was live before this site existed. Each one below was read back on chain before it was written into the config.

The data

• Price feeds published by Robinhood on Robinhood Chain, in the Chainlink aggregator shape. Plumb reads them; it does not operate, fund or influence them.
• Morpho Blue's market list, used only to discover which feeds exist. Plumb does not lend or borrow.
• Blockscout's log index, which is how a chain that serves no log history can still be enumerated.
• ethers.js (MIT) in the browser, and Hardhat for the forked-chain test suite.

The name

A plumb line is a weight on a string. Masons have used one for six thousand years for the same reason this site exists: it is an outside reference. It does not care what the wall thinks it is doing.
