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
Bitcoin is the largest crypto asset by market cap but mostly idle. Multiple BTC standards (native, wrapped, LSTs) fragment liquidity across chains — and the fast-growing Move ecosystem (Aptos, Movement) had no native BTC liquidity layer.
The Solution
Echo unifies fragmented BTC variants into a single chain-specific receipt token (aBTC, mBTC) backed 1:1 by locked reserves, then exposes that liquidity to a money market, yield strategies and leveraged BTC products entirely on-chain.
Why it Matters
First BTCfi infrastructure built natively on Move; ~65% of all BTC bridged to Aptos is aBTC. Combines a custodial BTC bridge, an oracle-secured Compound-style money market, and convertible-note leverage (eMSTR) under a single vetwECHO gauge-voting governance.
