The Morpher protocol replaces middlemen, such as brokers, exchanges, and counterparties, with an incorruptible protocol on the Ethereum blockchain. Morpher offers an Ethereum-based token, MPH, that can be staked on price development in a market, such as the Apple stock. The underlying protocol represents how markets are traded on the blockchain, without actually trading the underlying stock, commodity, or currency. Some of the features users can expect: free tokens when registering, zero transaction fees, perfect liquidity, verifiable & transparent execution, leverage support, stop loss and take profit capabilities.
