TrustedCoin helps make Bitcoin wallets safer.

TrustedCoin is a non-custodial Bitcoin transaction cosigning service. Multisignature wallet architectures that incorporate non-custodial 3rd party cosigners can provide an additional layer of security for user funds. TrustedCoin's APIs allow wallet developers to easily add such layers to their products. TrustedCoin's most visible API deployment is its integration with the Electrum wallet's 2FA plugin.
