According to Bitcoin Magazine, Bitcoin software provider Breez announced that applications built on its Breez SDK now support users receiving stablecoin payments from over 30 networks using their Bitcoin balance.Breez stated that after the recipient selects the network and amount of the payer, the SDK generates a deposit address and displays the amount received, while the payer pays from their wallet as usual; Flashnet completes the exchange in the background, and the funds ultimately enter the recipient's non-custodial wallet in the form of Bitcoin, or in the form of USD if the stable balance feature is used.In June of this year, Breez launched the ability to send USDT/USDC, allowing a single Breez-powered balance to transfer stablecoins bi-directionally across almost all networks. This update is the latest in a series of usability upgrades, following the rollout of features such as Passkey login, Cash App instant account opening, and stable balance. Breez also launched a reference application called Glow in August to showcase the capabilities of the SDK.The Breez SDK is a developer toolkit that allows applications to add Bitcoin payments without having to build their own payment infrastructure, covering wallet creation, sending and receiving, and Lightning Network payments. Developers can provide Bitcoin functionality with minimal code, without needing to run nodes or manage liquidity.In July of this year, Breez announced a partnership with Turnkey, allowing developers to add non-custodial Bitcoin support to wallet applications running on their own servers.
