APT Systems, Inc. is announcing it has launched Spera (SPRA) on the Mainnet in preparation for making the Spera stablecoin available for purchase. A Mainnet is a blockchain that transfers digital currency from senders to recipients which are then recorded on a distributed ledger. This differs from a Testnet, which is essentially the testing of such a transaction.

Mainnets are the actual “end product”, which makes a stablecoin available for the public to buy and use. Spera is a stablecoin, meaning it is backed by collateral assets so that the value of Spera will always be $1. Earlier this year, in preparation for going live with Spera, APT Systems created a pre-sale form where investors were invited to provide information and an indication of the number of stablecoins they plan to purchase. APT Systems is developing Spera to work seamlessly with its Verifundr digital 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 portion of Verifundr makes it ideally suited for escrow and payment functions, while Spera provides for payments and the simple transfer of escrow funds both domestically and internationally.
