Conservative · Min capital $500-$10K · 5% annual return
Starter tier, open-term access
Built for smaller first investments. Minimum capital range $500-$10K, with a 5% target annual return and flexible withdrawal access.
Disciplined returns, at institutional scale
The returns platform trusted by long-term investors, treasuries, and digital-asset funds. Conservative, Balanced, and Growth strategies, qualified custody, audited platforms, transparent annual return ranges.
Custody, audit & strategy partners
Most digital-asset return products promise a fixed daily payout and pool your assets into an opaque book. The rates fall apart the moment a market wobbles, and you find out after.
springb2 is built differently.
A different returns architecture.
Choose a strategy
Conservative, Balanced, or Growth. Each one publishes a target annual return range and a lock-in term. No fixed daily promises.
Fund your account
Deposit BTC, ETH, USDC, USDT, or SOL. Funds move into segregated accounts at a qualified custodian, never into a springb2 operating account.
Earn returns, withdraw on schedule
Returns accrue from network rewards and audited lending platforms. Withdraw at term end, or anytime on open-term strategies.
Conservative. Balanced. Growth. Yours.
Four strategies, one account. Invest in any tier independently. They all share the same custody, audit log, and withdrawal mechanics. Returns fluctuate with market conditions; past performance doesn't predict future returns.
[02]
Balanced · Monthly capital $20K-$50K · 9% annual return
Monthly investing tier
Designed for recurring monthly contributions in the $20K-$50K range, targeting a 9% annual return with diversified, risk-aware management.
[03]
Growth · Capital $50K-$100K · 14% annual return
Higher-capital growth tier
For larger investments between $50K-$100K with a 14% target annual return, using higher-return strategies that are still fully disclosed.
[04]
Institutional · 1-year term · Capital $100K+
Long-horizon institutional tier
Built for larger mandates starting at $100K with no upper cap. One-year fixed term with reporting and controls for treasury and fund workflows.
For institutions & treasuries01020304
The returns platform built like an institution.
Treasury-ready custody, a portfolio across three strategy tiers, a named source behind every percentage point of return, and the controls your auditor expects.
Qualified custody
Assets held in segregated accounts at BitGo Trust and Anchorage Digital. Regulated qualified custodians, never a springb2 operating account.
Multi-asset investments
Invest BTC, ETH, USDC, USDT, and SOL across Conservative, Balanced, and Growth strategies, independently or as a blended portfolio.
Transparent return sources
Network rewards, audited lending platforms, and risk-managed trades. Every percentage point of return is attributable to a named source on your statement.
Audit-grade controls
Multi-party withdrawal approvals, role-based access, downloadable transaction logs, and read-only seats for accountants.
