Score history
This rating is re-checked every month. A point is recorded for every check, so a flat line means we looked and nothing moved. Hover anywhere on the chart to see what moved that month, and by how much.
The Problem
Synthetic-asset protocols typically force users into a single collateral type, illiquid debt markets, and slippage on swaps between synthetics.
The Solution
Metronome accepts a broad set of productive collateral (including Vesper yield-bearing receipts) and enables zero-slippage oracle-priced swaps inside its Synth Marketplace, with cross-chain msAssets via LayerZero.
Why it Matters
Productive-collateral CDPs + zero-slip internal synth swaps + LayerZero-OFT cross-chain synthetics in one stack, governed by a 9-year-old crypto team (Bloq / Jeff Garzik).
