# 3.7 Full cross-chain transaction aggregation

Global top centralized exchanges are continually troubled by security issues, making decentralized trading an unstoppable trend. DeFi Mall, relying on its underlying infrastructure development, is committed to becoming the best partner in global distributed finance and aggregated trading. DeFi Mall's cross-chain aggregation trading achieves true decentralization of asset trading and management through cross-chain protocols:

* **Cross-Chain Multi-Currency Wallet** DeFi Mall's cross-chain aggregated trading digital wallet is a multi-asset exchange wallet based on cross-chain technology, achieving complete decentralization of services. The wallet's contracts include remittance and lending contracts, where the former handles multi-faceted financial services like cross-chain transfers and remittances, and the latter ensures the security of third-party profitable services such as savings appreciation, quantitative services, lending, OTC, etc. DeFi Mall's digital wallet is a wealth management gateway for users, integrating news, app downloads, and decentralized wallet functions. Users can safely use all integrated features on the wallet through contracts.
* **Blockchain Financial System** Inspired by the internet's spirit of "openness, equality, sharing, and collaboration," its core essence is to allow everyone to freely trade digital assets. Currently, DeFi Mall's cross-chain aggregated trading supports cross-chain transfer services for mainstream currencies like BTC, ETH, LTC, XRP, USDT, etc. As more digital currencies are launched on DeFi Mall's platform, advertisement services will follow suit, reaching more people and communities and realizing the inclusiveness and convenience of financial assets. Additionally, based on the open, autonomous, and inclusive nature of blockchain finance, DeFi Mall creates various blockchain financial application scenarios, maximizing the advantages of blockchain technology in asset freedom.
* **DeFi Mall Smart Trading** Using blockchain for asset trading is faster and cheaper. The decentralized, transparent distributed ledger eliminates intermediaries, trading permissions, and regulation, and also eradicates cumbersome paperwork that slows down processes.
* **DeFi Mall Smart Cross-Border Payments** Cross-border remittances can be slow and expensive, with a high probability of errors due to numerous banks and intermediaries involved. Companies including Abra, AlignCommerce, and Bitspark already offer fast and cheap remittance services powered by blockchain, and blockchain developers are collaborating with banks to provide same-day international remittance services.
* **A Free and Autonomous Financial Community** Traditional centralized social platforms store all user information on their operational servers, with operators holding all user data. DeFi Mall reforms this centralized model using blockchain's irreversible distributed ledger technology, creating a new peer-to-peer communication mode. Users can decide their personal data on the blockchain network, with no server records saved upon deletion. In traditional finance, customers choose services based on trust and expectations, often rooted in centralized endorsements, collateral, or tangible experiences. When unendorsed services are offered, users often feel lost and find it hard to shift their mindset. Blockchain resolves trust issues through decentralized encryption systems and smart contracts, further achieving community autonomy. On the path to freedom, Defimall aims to establish a completely autonomous and efficient community through cross-chain aggregated trading technology. Using lending contracts, traditional service providers can offer services to more users via DeFi Mall's platform, ensuring data and financial security for users utilizing these services.
