Introduction
INVSBL is a zero-knowledge privacy infrastructure for confidential stablecoin and digital asset transfers.
It enables fully private payments, payment requests, and settlement flows on Solana, Base, and Ethereum without publishing permanent financial records on public blockchains.
INVSBL operates as a transaction-level privacy rail, usable directly by individuals or integrated programmatically by applications, DAOs, and financial operators.
1. Complete Transaction Privacy
1.1 Protected Information
When a transaction is executed through INVSBL, the following data is not exposed:
Wallet identities
Addresses are never exposed or linkable
Account balances
Financial positions remain completely hidden
Transaction counterparties
Sender-receiver relationships are unknowable
Transaction graphs
Relationships between transactions cannot be constructed
Historical activity
Past transaction patterns are undetectable
No transaction metadata is made publicly observable.
1.2 Privacy Guarantees
Block explorers, analytics platforms, and indexers cannot:
Link participants together
Reconstruct behavior
Track activities over time
Identify relationships between parties
Each transaction is cryptographically isolated, making it impossible to connect transactions or identify relationships between participants.
2. Privacy Rail
INVSBL is not a wallet feature, mixer, or optional add-on. Confidentiality is inherent to how transactions are executed.
Native asset compatibility
Assets remain standard SPL tokens on Solana
Assets remain standard ERC-20 tokens on EVM chains
No wrapped, synthetic, or derivative assets are created
Fully compatible with existing wallets and infrastructure
Zero-knowledge enforcement
Privacy is guaranteed through cryptographic proofs
No reliance on asset changes or trusted parties
Base layer settlement
Transactions are settled on the underlying blockchain
Network security and finality are preserved
Transaction validity is publicly verified
Transaction details remain non-observable
Payments achieve both finality and privacy:
✓ Cryptographically verified
✓ Cannot be reversed
✓ Reveal no public information
3. What INVSBL Does Not Do
INVSBL does not attempt to obscure public data after it has already been exposed.
3.1 No Reliance On
Requires careful address management
Automatically enforces address isolation
Needs coordination between users
Operates without participant coordination
Relies on trusted operators
Zero-knowledge proofs replace trust
Depends on anonymity set size
Does not rely on anonymity sets
Uses probabilistic obfuscation
Uses deterministic zero-knowledge execution
3.2 Non-Degrading Privacy
Transaction confidentiality does not weaken over time.
Transaction count
No impact
Network size
No impact
Time
No impact
Analysis techniques
No impact
There is no accumulation of metadata, behavioral graphs, or historical linkage that can be analyzed retroactively.
3.3 Permanent Protection
If a transaction is routed through INVSBL, no system, now or in the future, can determine:
Who was involved
How funds moved
Whether actions are connected
4. System Design and Boundaries
INVSBL provides privacy at the transaction layer, not identity management or asset custody.
4.1 What the Protocol Does
Transaction validation
Uses zero-knowledge proofs to verify correctness
Metadata privacy
Enforces privacy for all transaction metadata
Network compatibility
Maintains compatibility with underlying blockchains
Transaction isolation
Ensures cryptographic isolation between transactions
4.2 What the Protocol Does NOT Do
Asset custody
Does not custody user assets or control private keys
Token modification
Does not modify or wrap underlying tokens
Synthetic assets
Does not introduce synthetic or derivative assets
Trusted parties
Does not require trust in third-party operators
4.3 Cryptographic Trust Model
All confidentiality properties are enforced cryptographically and remain intact even in hostile environments, including against:
Blockchain analytics firms
Infrastructure and node providers
Network observers
Nation-state surveillance
The INVSBL operator itself No party, including INVSBL, has access to private transaction data.
5. Who INVSBL Is For
INVSBL is built for users and organizations operating on stablecoin payment rails who require non-public transaction execution.
5.1 Target Users
Individuals Peer-to-peer transfers without wallet exposure
Freelancers and Contractors Income without public transaction histories
Marketing and Digital Agencies Contributor and partner payments without visible structure
Small Businesses Treasury, payroll, and supplier payments without public records
5.2 Uniform Transaction Treatment
Every transaction is processed identically, regardless of:
Amount
Frequency
Sender type
Use case
Supported workflows include:
Peer-to-peer payments
Treasury operations
Cross-border settlements
Automated payment flows
Operational and enterprise transfers
6. Why INVSBL Exists
No Private Payment Standard for Stablecoins
Stablecoins inherit the transparency of the blockchains they run on.
There is currently no widely available infrastructure that enables non-public stablecoin payments across Solana and EVM chains without altering asset issuance or settlement.
INVSBL enables confidential transactions while keeping assets and settlement fully native to the underlying blockchain.
