Bathymark takes its name from the old way of measuring the sea: a weighted line dropped over the side to read the depth of the water. Sailors did not bet on whether the water would get deeper. They measured it, so they knew where they could safely go.
Crypto is usually shown as a casino: green and red numbers, racing tickers, everything tuned to make you act. We think that is exactly backwards. The honest thing on a public ledger is depth, how much liquidity an asset, a protocol, or a chain actually holds, and how that depth is moving. Deep water is safe water. Shallow water is where things lurch.
What you get
A live stream of readings in plain language, every chain and protocol shown as depth, the stablecoin cash layer read for stress, and a glossary that explains the water the way you would actually want it explained. All of it built on open data, with the limits stated out loud.
Why time is in blocks
You will notice the clock here is measured in blocks, not minutes. A blockchain has its own pulse, a new block roughly every twelve seconds on Ethereum, and that pulse is the honest unit of on-chain time. When the block height ticks up in the header, the chain is breathing.
This is an early instrument and it will get sharper. If something reads wrong, it is a bug, not a feature. See the methodology for exactly how it works.
