Stablesea

Stable Sea is a financial technology platform providing global cash management and liquidity for companies building in stablecoins. The Stable Sea Terminal lets businesses consolidate on-chain and off-chain accounts, settle money across 40+ countries, run fiat-to-stablecoin on/off-ramps for transactions up to $50M, earn yield through tokenized money-market funds, and hold Bitcoin in insured custody. The Stable Sea Terminal API is a bearer-authenticated REST API (OpenAPI 3.1) for managing organizations, liquidity providers and exchange rates, external payment instruments, offerings, quotes, and payout orders — with idempotent writes on all create operations. Surfaced as a Kindred Ventures portfolio company and enriched into the API Evangelist network.

Stablesea publishes 2 APIs on the APIs.io network: Liquidity Providers API and Organizations API. Tagged areas include Company, Stablecoins, Payments, Cash Management, and Treasury.

Stablesea’s developer surface includes documentation, API reference, signup flow, support, engineering blog, and 6 more developer resources.
