Card signs
The chip verifies the fleet permit, then signs a payment intent with its non-exportable P-256 key.
The card that signs money.
Ethereum and Solana, on the same physical card. One tap signs the payment inside the chip, with instant on-chain settlement and no wallet interaction at checkout.
POS submits
The terminal handles any compatible card, without prior registration or card-specific prewarming.
Network settles
Funds settle as a verifiable transaction on EVM or SVM rails.
What we built
One physical card. One tap. Ethereum or Solana. The key stays inside the chip, whichever network carries the payment.
For acquirers and sub-acquirers
A new payment method your terminal fleet can understand.
Venturus Card is not an intermediary for moving numbers in a private database. Every tap is an instantly verifiable blockchain transaction.
The partner opportunity is simple: integrate the rail once, distribute through the machines you already operate, and give merchants access to card-present on-chain payments without changing the checkout ritual.
System
Three pieces. One checkout.
Physical card
The same Java Card applet signs payment intents for EVM and SVM. The private key stays inside the chip, and larger payments require PIN confirmation.
Smart POS
An enrolled terminal obtains a fleet permit and reads the card in one NFC session. No card-specific preparation or second tap is needed.
Smart account rail
Safe accounts and payment modules on EVM, or program-controlled vaults on Solana, verify the signed intent and execute the transfer.
Fleet control
Your terminals. Your rules. Verified by the card.
A hosted controller connects terminal operations to the chip's authorization checks, without taking custody of customer funds.
-
Enroll and identify
Each terminal authenticates with its own cryptographic identity. Installing the app alone does not grant access to card payments.
-
Authorize and revoke
Operators control allowed networks, tokens and merchants, and can revoke a terminal's access to new payment permits.
-
Verify inside the chip
The card checks a fleet-signed permit bound to its fresh challenge and the exact payment. No valid permit, no payment signature.
-
Follow the operation
Authenticated terminal activity, permits, denials and reported payment outcomes give operators a view of their fleet.
Why it matters
It feels like a card payment because it is one.
No private key leaves the card.
The card is the signer, not a prop for a cloud wallet.
No wallet training at the counter.
The merchant enters amount, the customer taps, the terminal handles the rails.
The same card, Ethereum and Solana.
One chip authorizes payments on EVM and SVM, with independent balances on each network.
Pilot
We are looking for payment partners who move real volume.
If you operate terminals, merchants, acquiring relationships, or a payment lab, this is the moment to see it live. Venturus can bring the working prototype, physical cards, POS flow, and technical roadmap.
