How to perceive Aptos entry into the Echo Protocol

How to view the latest Pre-seed round financing of BTCFi track @EchoProtocol_? In addition to Arthur Hayes’ participation, the biggest highlight is that @Aptos public chain has entered the game, directly providing a 10% APY income bottom support. Why? Let me briefly explain my understanding:
1) It must be emphasized that the continuous attention to the BTCFi track is not only because a large number of infrastructures built by the BTC ecosystem need DeFi Moment, but more importantly, it is the main channel connecting a large number of EVM-Compatible chains, Move-based chains, Solana-based chains, RWA application scenarios, and other native BTC asset pools.
Although other chains also have various Wrapped versions of BTC for DeFi, the BTCFi that can achieve asset cross-chain in a native way and aggregate diverse income possibilities clearly attracts the attention of every BTC miner, institution behind ETF, and BTC Holder. This is the fundamental reason why Echo Protocol, a project in the Aptos ecosystem, enters the BTCFi.
2) Echo Protocol has chosen @BSquaredNetwork’s cross-chain bridge solution. Users’ BTC will be cross-chained to B² Network through B² Bridge, and then it will be converted into uBTC through the pre-deployed UniRouter and further synchronized into aBTC in the Aptos ecosystem, generating income by depositing aBTC into the Lending platform.
This technical logic is not complicated and originates from the fact that BSquare is a relatively hard-core modular BTC layer2 solution: B² Hub provides a modular DA layer, and zkBridge provides a secure cross-chain method.
Specifically: B² has opened a MPC+TSS trusted secure multi-signature address for depositing BTC assets. When the zkOracle node monitors and records the inflow of the deposited assets, it will generate a ZK Proof to prove the deposit status. This proof will be passed to the AA smart contract deployed on B². After verifying the ZK proof information, the contract will release the assets to the user’s address on the B² chain. In addition, with the constraints of the BitVM challenge mechanism, users can initiate challenges to the B² Hub if they doubt the change in the cross-chain asset status, thereby ensuring the security of asset cross-chain.
Since zkBridge is specially customized for B² by @PolyhedraZK, it can support the cross-chain interoperability of Move-based public chains and BTC chains. This is also the key technology for Echo Protocol to quickly enter the BTCFi with the help of B² Network.
3) It is well known that the Move language has natural commonality with the object-based account structure and Bitcoin UTXO structure. Move-based public chains have performed well in the market and ecology during this period, especially Aptos and SUI, which, thanks to the security and financial preference characteristics of the Move language, have always been regarded as the main battlefield of “new DeFi”.
In fact, after Aptos achieved a TPS of tens of thousands per second in public chain performance, it has spared no effort to expand the DeFi application ecology.
In the past six months, Aptos has cooperated with Tether to introduce the stablecoin USDT, and has also partnered with Ondo to access real-world assets (RWA). In addition, it has entered the gaming field and cooperated with NBCUniversal, a gaming and entertainment giant. It also has close cooperation with io in distributed AI models and more. With the outstanding performance of popular applications such as tapos cat, the user scale and transaction volume have reached top-level.
Based on this background, the strategic intention of #Aptos embracing the #BTCFi ecosystem is self-evident, and the positioning of Echo Protocol is an important bridge connecting these two ecosystems.
Moreover, after the achievement of this combination of strategic cooperation, Bsquare points, Echo points, and even Babylon points will be collected. Behind these expectations, there is also the real APT token reward from Aptos to provide bottom support.
(I have to say that the development support of the Move-based public chains, Sui, and Aptos foundations in the DeFi ecology is really extraordinary).
