Security & Features

Built like a vault, not a casino

Every layer of Vaultline is designed around one question: is this how a private bank would treat your assets?

🔐

MPC key custody

Keys are split across multiple secure parties — no single point of failure, no seed phrase taped to a monitor.

🧊

Cold storage by default

Long-term holdings live offline in geographically distributed vaults, moved only with multi-party approval.

📡

24/7 risk monitoring

Continuous anomaly detection watches withdrawals, logins, and market exposure around the clock.

⚙️

Automated staking

Idle assets earn on-chain yield with rewards auto-compounded and shown transparently, net of fees.

🧾

Tax-ready reporting

Every trade, transfer, and reward exports cleanly to your accountant — no spreadsheet archaeology.

🛡️

Independent audits

Proof-of-reserves attestations and third-party security reviews, published on a fixed schedule.

Pricing

Simple plans, no hidden spread

Flat, honest pricing for the fictional investor. Three tiers, nothing buried in the fine print.
