BitGo and Stable Sea have announced a partnership to expand B2B stablecoin payments and onchain treasury services for businesses. BitGo’s Crypto-as-a-Service (CaaS) infrastructure will be used to give Stable Sea customers regulated custody and the ability to buy, sell, and hold bitcoin and stablecoins in a controlled environment.
The deal is aimed at companies that want stablecoin workflows, but don’t want to build crypto custody and trading infrastructure from scratch.
A custody-and-trading layer for Stable Sea customers
Stable Sea will use BitGo’s CaaS stack to offer customers access to custodial wallet solutions, including the ability to hold and trade supported digital assets such as bitcoin and stablecoins. BitGo said it maintains insurance coverage on assets held in qualified custody.
In simple terms: Stable Sea is building the treasury product; BitGo is providing the regulated crypto “plumbing” underneath it.
Built for modern treasury workflows, not just trading
The companies positioned the partnership around treasury use cases—especially B2B stablecoin payments—and also flagged potential access to tokenized real-world assets, including tokenized money market funds and fixed-income products, where available and permitted.
That combination (payments + treasury + tokenized instruments) is basically the “CFO angle” of stablecoins: move value faster, keep better visibility over cash, and reduce cross-border friction.
Why BitGo is leaning into Crypto-as-a-Service
BitGo said its CaaS is an API-driven framework designed to help platforms offer secure, scalable digital asset services—covering custody wallet infrastructure and trading capabilities that can support treasury and transaction workflows.
Stable Sea described its platform as a way for businesses to move and manage stablecoins globally, orchestrate international payments, and convert between digital and local currencies with enterprise-grade controls.
Why it matters for crypto
- This is another signal that stablecoins are becoming treasury infrastructure, not just exchange settlement collateral.
- “Crypto-as-a-Service” models let fintechs ship stablecoin features faster, while outsourcing the hardest parts: custody, controls, and compliance.
- Tokenized money-market and fixed-income access hints at where onchain treasuries are going next: cash management plus yield-bearing instruments (where permitted).
- Regulated custody + insurance coverage is a key checkbox for enterprise adoption, especially for larger balances.
What to watch next
- When Stable Sea rolls out BitGo-powered custody and trading to customers, and in which regions first.
- Which stablecoins and assets are supported at launch (the release does not list them).
- Whether Stable Sea actually launches tokenized money market fund / fixed-income access, and under what eligibility rules.
- Any disclosure on fees, limits, or integration partners for on/off-ramps and cross-border settlement.
