Bitcoin payments processor BitPay has announced that Copay, its multisig bitcoin wallet, is set to leave beta today.

Copay, originally known as Cosign, aims to combat bitcoin wallet thefts by offering customisable security for businesses and individuals.

Like other multisig products, a predetermined number of parties must ‘sign off’ each Copay transaction before it is broadcast to the bitcoin network.

The app, which has been in development for over a year, is fully open-source and able to be “forked, changed, and developed by the community,” the company said.

The launch comes as multisig security is gaining ground among bitcoin companies. Just last month, UK-based digital assets service provider Elliptic partnered with Gem to offer a custodian service for the private keys of multisig wallets.

The californian bitcoin API developer, which has raised $3.3m to date, launched its multisig wallet API back in April.
