Onchain capital markets access, simplified.
Every function a modern treasury needs — subscribing to regulated funds, moving stablecoins across borders, allocating to bitcoin, reconciling to the general ledger — from a single account.
Put idle operating capital to work without giving up liquidity.
Automatically invest balances into SEC-registered tokenized money market funds. With WTGXX, redeem instantly the moment you need the cash back on the ledger.
Access to tokenized capital markets products from top-tier issuers

Yield accrues daily — including weekends and holidays
Automated cash management rules and thresholds
Why park the whole treasury in one place?
Most treasury teams end up over-exposed to a single bank, issuer, or fund simply because moving cash is slow. Stable Sea lets you spread balances across a diverse set of money market and short duration income funds and rebalance in seconds when exposure drifts.
Invest across multiple SEC-registered mutual funds
Blend money market and short duration income funds by duration and risk
Set allocation limits that mirror your investment policy
Add bitcoin to your balance sheet — from the same account.
Purchase, hold, and report on bitcoin alongside your regulated funds and stablecoins. No separate exchange, no separate custodian, no separate reconciliation.
Buy BTC directly on the terminal
Institutional-grade insured custody up to $250M
Manage BTC alongside your stablecoin and tokenized-fund treasury
