What it does
  • Breez SDK is a developer toolkit that lets apps and services add instant, self-custodial bitcoin and stablecoin payments and transfers.
More detail
  • Developers integrate it with a few lines of code so end users can send and receive bitcoin over Lightning and Spark, plus USDT/USDC, without the developer taking custody of funds.
Best for
  • Crypto wallets, neobanks, swaps and bridges, remittance apps, messengers, social apps and iGaming operators that want to add self-custodial bitcoin and stablecoin payments without holding customer funds or taking on money-transmitter licensing.
Pricing
  • The Breez SDK is free for developers with no licence fee, though a free-to-request API key is required.
More detail
  • End-user fee schedules are referenced on the site but the exact amounts were not captured
  • prior implementations describe static low fees with no end-user setup fees, while on-chain withdrawals in
Main limitation
  • Teams that need fully trustless designs, since Spark relies on a shared-signing federation of operators rather than trustless consensus.
More detail
  • Also a poor fit for buyers who need the Cash App deposit rail outside the US and UK, or bitcoin payments in New York, or a testnet version of the cross-chain Cash App flow, which is mainnet-only.
