We are a Stablecoin-as-a-Service (SCaaS) company, providing stablecoin infrastructure and fiat on/off-ramps for blockchain foundations and Web3 applications. The total stablecoin market is $150B+ now but over 95% of blockchain networks lack native stablecoin presence in their ecosystems. Additionally, most Web3 applications on these blockchains don't have good fiat-to-stablecoin gateways, either, with the average fiat on/off-ramp transaction fee for stablecoins running as high as 20-25% on some platforms. This is why we are here to solve those problems! At Stably, we provide you with the cheapest and easiest methods to buy/sell stablecoins across many different blockchains. Not only do we support USDT and USDC on developed blockchains like Ethereum, Solana, Avalanche, and Stellar, we also have our own USDS stablecoin that has been expanded across 10+ emerging chains, including Harmony, Tezos, VeChain, Chia, DigitalBits, and ICON. USDS is a US Dollar stablecoin backed 1-to-1 by bank deposits held in a trust for the benefit of token holders by our regulated trustee partner Prime Trust, a Nevada state-chartered trust company and SEC-qualified custodian. Stably is a stablecoin technology provider to Prime Trust and we do not have access to the USD collateral. We also publish monthly attestation for USDS from Cohen & Company, an independent auditor who ensures that USDS is always fully collateralized. Currently, we support user onboarding in 200+ countries and we accept a wide range of payment methods, including Fedwire, SWIFT, ACH, credit and debit cards with VISA and MasterCard. We are constantly working to support more countries, payment methods, blockchain networks, stablecoins, and other listed assets in the near future. For more information, please visit: ?
