One vault. Unlimited AI. Pay per compute.

Awaiting network data...
Centrasys creates a single cryptographic vault on Solana. Instead of giving credit card details to every AI platform, you deposit SOL once into your PDA. Authorized providers deduct micro-payments on-chain — per request, per compute, with full auditability. The deployed Anchor program enforces spending caps and owner custody at the smart contract level.

THE FLAW IN
THE SYSTEM.

The current AI ecosystem forces you to trust every platform with your payment data. Credit cards are scattered across databases. You lose visibility and control over what you are actually paying for — with no on-chain audit trail.

1 Vault to replace them all.

Centrasys holds your SOL in one on-chain vault PDA. Your vault key authorizes compute limits per session — providers deduct exactly what is used, per request. Nothing more.

THE PROTOCOL.

01

On-Chain Vault PDA

A deterministic Solana PDA seeded from your public key. Any provider can verify your vault independently — no trusted intermediary required.

02

Per-Request Deduction

SOL is deducted on-chain via the deduct_fee instruction. Transaction caps are enforced at the smart contract level — the provider cannot overcharge you.

03

Full Custody

You always retain withdrawal rights. The withdraw_vault instruction returns all remaining SOL to your wallet. No lock-up. No counterparty risk.

FRICTIONLESS
EXECUTION.

A.

Deposit SOL

Send SOL from your wallet into your vault PDA. Funds remain under your control via the withdraw_vault instruction — full custody, no lock-up.

B.

Generate Vault Key

Create a master vault key or derived AI keys. Set per-transaction deduction caps to protect your balance across every provider you connect to.

C.

Pay Per Compute

Execute AI workflows. Real SOL is deducted on-chain via the Centrasys Anchor program — every transaction is fully auditable on Solana Explorer.
