Safe sending: ethbox provides a unique solution to a problem in cryptocurrency trading that is as devastating as it is widespread. Accidentally sending funds to a mistyped or mistaken recipient address has already been the cause for hundreds of millions, if not billions, of financial damage. Harnessing the cryptographically unbreakable safety of the underlying Ethereum blockchain, ethbox provides a smart contract based digital escrow service to completely alleviate any risk of loss while sending cryptocurrency. Privacy: Sending funds through ethbox disrupts the chain of transparently trackable blockchain transactions, thereby obfuscating their origin and destination. For situations where discretion is required, users have the option of wrapping ethbox transactions with an additional layer of privacy, for a small increase in service fee. When using this added privacy feature, both sender and recipient addresses are encrypted locally on users’ computers. No clear-text addresses are ever transmitted into the internet or stored on-chain, and users may remain anonymous to each other. Any attempt to reconstruct added-privacy transactions between ethbox users becomes tremendous effort, if not impossible. OTC On top of securing transaction, ethbox offers an easy and convient way of trading Ether and ERC-20 tokens. Funds can be sent & requested a single transaction, which may only be fulfilled once both the sending and receiving party have put in their part. This gives users a safe, reliable environment for OTC trading that is immune to any form of fraud or scam. Safeguarded by the ethbox smart contract, ethbox OTC transactions are guaranteed to take place in the only way that is acceptable, being fair and mutually beneficial for both parties.
