For friends who haven't dropped out of school, this episode feels like there's meat to eat On July 2nd, BN Alpha launched Echo Protocol with the token ECHO. I was in a daze because 10 minutes ago someone asked me if I wanted to buy ECHO KYC. I quickly clicked on it and checked, and it turned out ⬇️ This is @ EchoProtocol_ from Aptos ecosystem, not that fundraising platform. On Defillma, as the largest source of BTC liquidity in the Aptos ecosystem, 270M of the Echo Protocol 878M TVL is aBTC (BTC on Aptos). It has to be said that recently, public blockchains have been fiercely competing for BTC, with Sui, Sei, and even Solana all competing. LSTs such as Lombard and Lorenzo have also started to do Bitcoin liquidity on multiple chains. But at present, other ecosystems have not seen mature protocols that can be played. Echo has TGE, indicating that BTCFi on Aptos has been implemented. I searched the history and on May 27th, @ Aptos official Twitter posted a special message: Aptos is for BTCfi, and now there are BTC worth over $400m in the ecosystem. Echo brought in 30 million bitcoins in just one event, xBTC, in collaboration with OKX... It's terrifying. In addition, there are partners such as Thala, Hyperion, Echelon, and even expanded to multiple chains such as Morph, Movement, Hemi. What exactly is Echo? Its own definition is BTC liquidity and aggregation infrastructure. The infrastructure referred to here includes a three-layer product architecture consisting of liquidity layer, revenue amplification layer, and LST infrastructure layer. Please find time to study it in detail. Aptos strongly promotes BTCFi and Echo Protocol's robust products and data, coupled with this being the first Aptos project to go alpha, overall: Hope that those who repeat can see hope 🤪。
