Sling Money

Sling Money — now operating as Morse, built by Avian Labs — is a consumer stablecoin-based global money-transfer app that lets people receive, hold, move, spend, send, and invest across 150+ countries and 40+ currencies from a single mobile app. Transfers settle on the Solana blockchain using regulated stablecoins (Paxos USDP, Circle EURC/USDC), and users can spend anywhere with a Visa card issued via Lead Bank. Avian Labs is MiCAR CASP-authorized by the AFM in the Netherlands (registration 41000005), a FinCEN-registered US Money Services Business (31000327638265), NMLS-registered (ID 2639252), and ISO/IEC 27001:2022 certified. Morse is a consumer fintech product and does not currently publish a public developer API, SDKs, or API documentation; this profile captures its identity, legal, security, and compliance surface.
