Echelon

Echelon receives a B- risk grade (29/100) from Hindenrank, where lower scores indicate lower risk. Moderate risk — dominant Aptos lending protocol, but the four-BTC-bridge dependency is a unique vulnerability that multiplies custody risk The leading lending protocol on Aptos where you deposit crypto to earn interest or borrow against your holdings. It manages $400M in deposits across Aptos, Movement, and Initia. Its B- grade reflects the unusual risk of accepting four different wrapped Bitcoin tokens as collateral, each backed by a different bridge that could fail.

The key risks identified for Echelon are: (1) The protocol accepts four different Bitcoin tokens (sBTC, xBTC, WBTC, aBTC), each from a different bridge. If any one bridge gets hacked, the fake BTC becomes worthless but the loans against it remain, creating bad debt for everyone (2) Much of the current deposits came from people farming the ELON token airdrop. After the airdrop, this mercenary capital will leave, potentially spiking interest rates and trapping remaining depositors (3) The same code runs on three chains. A bug found on Aptos can be exploited on Movement and Initia before a fix is deployed, tripling potential losses
