Self-custody. On your server.

VP3 Coin wallet at bank.vp3.me. Deposits, transfers, tips, gifts, sub-wallets for family members. Solana bridge for stablecoin in/out. Keys live on your hardware — never on a third-party exchange.

bank.vp3.me — not your keys, not your coins. Yours.
What's Inside

A wallet that runs on your home server.

Crypto Bank is a non-custodial wallet that lives in your Cauldron install. Private keys are encrypted at rest with the same per-host master key as the rest of the data. Transfers, tips, and on-chain bridges are signed locally; nothing leaves the box without your explicit action.

VP3 Coin wallet
Native VP3 Coin balance, transfer history, send-to-username flow. Per-member sub-wallets so kids and partners get their own balance without a separate account.
Self-custody by default
Private keys generated locally, encrypted at rest with AES-GCM, never transmitted. Backup phrase shown once; you write it down.
Solana bridge (USDC in/out)
On-chain bridge to Solana for stablecoin deposits and withdrawals. VP3 Coin pegged 1:1 with USDC inside the platform; bridge is read-only by default.
Tips, gifts, transfers
Send VP3 Coin to any member or any *.vp3.me handle. Pre-built micro-gift catalog (coffee, lunch, etc.) for casual transfers. Transaction history searchable.
Sub-wallets per member
Each Family Brain member gets a sub-wallet with operator-set spending limits. Kids get an allowance; teens get a debit-style sub-wallet; you stay the operator.
Treasury contributions
Optional: contribute compute or storage to the VP3 Network Treasury. Earn VP3 Coin payouts proportional to contribution. Opt-in, kill-switchable, fully transparent.

Hold your own keys.
