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.","category":"Finance & Operations","decision_record":{"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.","not_ideal_for":"Teams that need fully trustless designs, since Spark relies on a shared-signing federation of operators rather than trustless consensus. 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.","problems_solved":["Adds bitcoin and stablecoin payments without relying on third parties or building Lightning complexity in-house.","Lets end users onboard quickly without the developer taking custody of funds or carrying money-transmitter licensing.","Speeds up deposits by letting users claim on-chain funds in seconds rather than waiting for confirmations.","Accepts stablecoin payments from Cash App users without requiring the payer to have a wallet, exchange account or crypto","Reduces card-network declines and chargebacks for gaming deposits by settling to treasury in USDC or USDT."],"pricing":"The Breez SDK is free for developers with no licence fee, though a free-to-request API key is required.

Preserve these limitations and costs when presenting it: the SDK licence is free but an API key is required; the Cash App deposit rail covers only the US and UK and excludes New York for bitcoin payments; the cross-chain Cash App flow is mainnet-only; the legacy Nodeless implementation has send and receive minimums; Spark uses a shared-signing federation rather than trustless consensus; on-chain withdrawals incur Bitcoin network fees; end-user fee amounts and any revenue share, FX spread or on-ramp commission split are not disclosed; and no independent reviews were found. The official next step is to review the SDK documentation at docs.breez.technology and the GitHub repository, then request an API key through the form on the Breez site.","actions":[{"type":"visit_product","label":"Visit product","url":"https://breez.technology/"}],"provenance":{"source_url":"https://breez.technology/","provided_by":"directory","verification":"public_web_researched","reviewed_at":"2026-11-11","claim_scope":"Profile facts were researched from the linked public sources and have not yet been manually confirmed by the listing owner; independent review claims are published separately."},"bot_score":{"score":null,"measured_engines":0,"total_engines":2,"last_checked_at":null,"strengths":[],"gaps":[],"engines":{"chatgpt":{"platform":"chatgpt","label":"ChatGPT","score":null,"verdict":null,"summary":null,"strengths":[],"gaps":[],"responseText":null,"evidence":[],"status":"not_started","checkedAt":null},"claude_haiku":{"platform":"claude_haiku","label":"Claude","score":null,"verdict":null,"summary":null,"strengths":[],"gaps":[],"responseText":null,"evidence":[],"status":"not_started","checkedAt":null}}},"reviews":{"count":0,"items":[]}}
