APT Systems, Inc. announced that it has continued diligent preparations for release of its stablecoin, Spera?including adoption of the new symbol SPRA for the Ethereum-based digital coin. The company is developing Spera to work seamlessly with its application for US Dollar conversion to Spera inside the Verifundr escrow application, which uses smart contracts in part to serve as a neutral third-party to ensure funds are duly released upon both parties fulfilling their contractual obligations. The blockchain-supported architecture of Verifundr makes it ideally suited for escrow and similar payment functions needed, and Spera, a true fiat backed stablecoin, provides users liquidity and protection from volatility.
