The key features of SFX

Simultaneous document exchange

SFX Exchanges orchestrates simultaneous disclosure of documents between two parties. The platform allows a user to upload their documents and begin an exchange simply by sending it to their counterparty's email address. The document will remain inaccessible, until the counterparty uploads their respective document, upon which both are released simultaneously. It is also possible to send exchanges to unregistered users what makes SFX viral as leveraging SFX for new users is easy and simple.

Securely transfer documents

SFX Transfers offers a simple, but highly secure mechanism for sending documents to other parties. Each document can be tracked and managed to ensure both parties acknowledge receipt and email notifications alert users when a new Transfer has been received. Both parties can keep in touch via an integrated chat messenger. It is a simple but highly effective way to ease inefficiencies in business processes that require sending documents to counterparties such as banks, insurances and suppliers.

Smarter management

SFX helps you to seamlessly manage your organisation - create new teams, invite and delete members. The team management section has a dynamic and immersive look to easily navigate and perform smarter management. The built-in-chat functionality also eliminates the need for separate E-mail communications.

Security meets a modern design

A well-designed interface is optimized for the intuitive experience that powers the entire platform. Everything, from the registration to orchestrating an exchange, has been designed to provide the best experience of digitally exchanging assay certificates and/or transferring confidential information in a safe way. The intuitive navigation eliminates the need for training and the built-in Help Center section provides assistance if necessary.

How our customers leverage SFX

Exchange in Commodities Trading

Metal and soft commodities trading often involve processes whereby documents need to be simultaneously exchanged. For example, inspector quality reports or contracts between two trading counterparties. Traders can easily upload their respective documents to SFX without a need for courier services. The documents will stay locked in the system, until both parties have uploaded their respective documents.

Transfer in Trade & Finance

SFX Transfers enables the secure sending of the common documents needed to facilitate the financing and insurance processes within trade. SFX Transfers has been applied to manage the sending and receipt of trade finance documents to support the processes such as the management of credit and insurances. The advantage here is that the traders can ensure all information is received by trade finance departments quickly, thus reducing lead time that can cause them costly delays.

Invoice management

With an increase of fraud has grown in, a number of our customers are leveraging SFX transfers for securely sending invoices directly to their suppliers to help eliminate significant fraud. Phishing scams or email spying techniques often intercept payment instructions to fraudulent accounts. This process is secure, and the files sent via SFX can only be decrypted by the respective receivers and with no threat of external parties intercepting the content for the purposes of tampering by fraud.

Smart Contracts

Smart contracts are a means of making business processes automated and transparent by Blockchain. Smart Contracts became very popular by the notion that they audit and track all activity, hence facilitating a tamperproof ledger. SFX uses smart contracts to ensure all business logic is made transparent and all activity is audited. They also use approaches like escrow to support our SFX Exchanges feature.
