ABSTRACT
Vettor (VTT) is a purpose-built Layer 1 blockchain that serves as the DLT infrastructure for the distribution, trading and governance of regulated financial instruments backed by real world assets. Vettor does not replace the regulated vehicles that legally hold the underlying assets, nor the authorized registrars that maintain the legal ledger. It provides the technical rail that makes issuance, secondary trading and holder governance efficient, transparent and programmable, while the regulated layer preserves legal effect and supervisory oversight.
The network uses Delegated Proof of Stake (DPoS) consensus with up to 21 validators producing 3-second blocks with BFT finality. Smart contracts are written in Rust and compiled to WebAssembly (WASM), providing near-native execution speed with deterministic gas metering. A built-in decentralized exchange (DEX), an Ethereum bridge for cross-chain liquidity, and on-chain governance for both protocol parameters and individual assets complete the platform.
The VTT token is used for gas fees, staking rewards, governance voting, and trading. A deflationary mechanism burns 70% of all gas fees, while block rewards maintain network security through a 5% annual inflation rate split 80/20 between block producers and the community treasury.
THE PROBLEM
Real world asset tokenization has been a persistent promise of blockchain technology, yet adoption remains limited. Current approaches suffer from fundamental structural issues that prevent meaningful scale.
- //Fragmented infrastructure: asset issuers must assemble a patchwork of smart contracts, oracles, custodians, and compliance providers across multiple protocols, each with its own trust assumptions and failure modes.
- //No native compliance layer: existing blockchains treat identity and compliance as an afterthought. KYC/AML enforcement relies on off-chain wrappers that can be bypassed, creating regulatory risk for issuers and investors.
- //High costs and slow settlement: deploying and operating tokenized assets on Ethereum mainnet requires significant gas expenditure. Layer 2 solutions reduce costs but introduce bridging complexity and fragmented liquidity.
- //Illiquid secondary markets: tokenized assets often lack trading venues. Without a built-in exchange, holders are trapped in positions with no price discovery or exit mechanism.
- //No on-chain governance for asset holders: token holders of real world assets have no native mechanism to vote on revenue distribution, management changes, or operational decisions affecting their investment.
THE SOLUTION
Vettor addresses these limitations with a three-layer model that separates legal ownership, economic rights and DLT registry. The underlying assets are held by regulated vehicles (SPV under Italian Law 130/1999, closed-end AIFs, SICAF). The financial instruments issued by these vehicles are recorded on a DLT registry maintained by an authorized registrar. Vettor provides the blockchain infrastructure — wallet, secondary trading, governance and cross-chain interoperability — that sits on top of this regulated layer.
- //DLT infrastructure: a purpose-built chain that optimizes distribution, trading and governance of regulated financial instruments. Not a substitute for the regulated vehicle or the legal registry.
- //Regulated partnership model: Vettor operates in partnership with entities authorized by the competent authority (Consob in Italy) as registrars for the digital circulation of financial instruments. Legal effect of transfers is preserved through the registrar; Vettor provides the technical layer.
- //Integrated compliance: KYC/AML, investor eligibility and jurisdictional restrictions are enforced at the protocol level for regulated actions, consistent with the registrar's legal obligations.
- //Built-in secondary market: a constant product AMM provides continuous liquidity for security tokens, subject to the transfer restrictions encoded at the compliance layer.
- //Cross-chain distribution: the Ethereum bridge enables capital from the broader ecosystem to reach regulated Vettor issuances, while settlement and registry remain with the authorized registrar.
- //Holder governance: on-chain votes mirror the governance provisions of the underlying vehicle, giving token holders a programmable mechanism to exercise the rights granted to them by the vehicle's statute, fund regulation or indenture.
ARCHITECTURE
Vettor is designed as a relay chain that coordinates consensus, staking and — in a future release — cross-chain messaging to application-specific sub-chains. Today the relay chain operates as a single chain: the multichain registry, cross-chain message types and shared-security primitives are implemented and visible via vtt_listRegisteredChains, but routing between chains requires a relayer that has not yet shipped. CrossChainTransfer transactions are rejected explicitly until the relayer is active, to prevent funds from being locked in undeliverable messages.
CONSENSUS
VTT uses Delegated Proof of Stake (DPoS) with a maximum of 21 active validators selected by stake weight. Validators produce blocks in round-robin order with 3-second block times. Byzantine Fault Tolerant (BFT) finality ensures that once a block is confirmed by 2/3+1 of validators, it cannot be reverted.
CRYPTOGRAPHIC PRIMITIVES
| COMPONENT | CHOICE |
|---|---|
| Signatures | Ed25519 (Curve25519) |
| Hashing | BLAKE3 |
| Serialization | Borsh (Binary Object Representation Serializer for Hashing) |
| Smart contracts | WebAssembly (WASM) via Wasmer 5 runtime (Cranelift backend) |
| Address format | 20 bytes from BLAKE3(public_key), displayed as 0x + 40 hex chars |
SLASHING
Validators are held accountable through an evidence-based slashing mechanism that penalizes misbehavior while requiring cryptographic proof before any stake is forfeited.
- //Double-sign slashing: validators who sign two different blocks at the same height lose 5% of their total stake. Evidence requires two conflicting signed block headers from the same validator at the same height.
- //Downtime slashing: validators missing more than 50% of their assigned block slots in an epoch lose 0.1% of their stake.
- //Evidence-based: slashing requires cryptographic proof before execution. For double-sign, this means two conflicting signed block headers; for downtime, the chain tracks missed slots automatically.
- //Audit trail: all slashing events are recorded on-chain with full details (validator, amount, evidence hash, block height) for transparency and auditability.
WASM VIRTUAL MACHINE
Smart contracts are written in Rust and compiled to WebAssembly. The WASM VM provides deterministic execution with full gas metering. Contracts interact with the chain through native host functions for persistent storage, event emission, balance transfers, and access to block context (height, timestamp, caller address). This architecture delivers near-native performance while maintaining sandboxed security.
TOKEN ECONOMICS
VTT is the native token of the Vettor blockchain. It serves four primary functions: gas fees for transaction execution, staking for network security, governance voting power, and medium of exchange within the ecosystem.
ALLOCATION
| ALLOCATION | % | DESCRIPTION |
|---|---|---|
| Validator Rewards | 30% | Distributed via block rewards over 10 years |
| Ecosystem | 20% | Grants, partnerships, and liquidity mining programs to grow adoption |
| Team | 15% | 4-year vesting, 1-year cliff |
| Public Sale | 15% | Initial distribution via launchpad |
| Foundation | 10% | Reserved for long-term protocol development and maintenance |
| Treasury | 10% | Governance-controlled fund for community proposals and spending |
UTILITY
- //Gas: every transaction requires VTT for execution. 70% of gas fees are permanently burned, creating sustained deflationary pressure as network usage grows.
- //Staking: validators and delegators stake VTT to secure the network and earn block rewards. Minimum self-stake for validators is 100,000 VTT with a 21-day unbonding period.
- //Governance: VTT holders vote on protocol parameter changes, treasury spending, and chain registration proposals. Voting weight is proportional to staked amount.
- //Medium of exchange: VTT is the base trading pair on the built-in DEX and the primary token for launchpad participation and asset purchases.
DEFLATIONARY MECHANISM
70% of all gas fees collected by validators are permanently burned (removed from circulation). The remaining 30% is retained by the block producer. As network activity increases, the burn rate accelerates, creating a supply reduction that counteracts inflationary block rewards.
BLOCK REWARDS
New VTT is minted each block at a target rate of 5% annual inflation (adjusted dynamically based on the staking ratio). Block rewards are split 80% to the block producer and their delegators, and 20% to the community treasury, which is controlled by on-chain governance.
DEX & LIQUIDITY
VTT includes a native decentralized exchange (DEX) at the protocol level, eliminating the need for external AMM deployments. Every tokenized asset on VTT chain has immediate access to on-chain trading infrastructure.
CONSTANT PRODUCT AMM
The DEX uses the constant product formula (x * y = k) for price discovery and trade execution. Liquidity providers deposit equal-value amounts of two tokens into a pool and receive LP tokens representing their share. Swap fees are distributed proportionally to all LPs in the pool.
AUTO-LIQUIDITY FROM LAUNCHPAD
Every token sale conducted through the VTT launchpad automatically allocates a portion of proceeds to seed the VTT/vUSDT liquidity pool. This ensures that newly launched tokens have immediate trading liquidity from day one, without requiring manual market making.
MULTI-POOL SUPPORT
Any token pair can have a liquidity pool. This enables direct trading between any two assets on the chain without routing through a single base pair. Liquidity providers earn a share of all swap fees generated by their pool, proportional to their LP token holdings.
GOVERNANCE-CONTROLLED PAUSE
The DEX can be paused via a governance proposal, halting all swaps and liquidity operations. This provides a safety mechanism in case of oracle manipulation or critical bugs, allowing the community to freeze trading activity until the issue is resolved and a subsequent governance proposal re-enables operations.
BRIDGE
The VTT bridge enables bidirectional asset transfers between VTT chain and Ethereum (including Base L2). This connects the VTT ecosystem to the broader DeFi landscape, enabling capital inflows and providing VTT holders with access to Ethereum-based liquidity venues.
MECHANISM
- //Withdraw (VTT to Ethereum): tokens are burned on VTT chain, and a relayer releases equivalent wVTT (ERC-20) or USDT on Ethereum/Base.
- //Deposit (Ethereum to VTT): users send wVTT or USDC/USDT to the bridge contract on Ethereum. After confirmation, equivalent tokens are minted on VTT chain.
- //On-chain verification: every bridge operation is recorded on both chains with matching transaction hashes for full auditability.
WRAPPED VTT (wVTT)
wVTT is an ERC-20 token on Ethereum representing VTT locked in the bridge. It is fully backed 1:1 by VTT on the native chain. wVTT can be traded on Uniswap and other Ethereum DEXes, providing an on-ramp for Ethereum-native users and additional price discovery venues.
CURRENT MODEL: CUSTODIAL RELAYER
BRIDGE SECURITY
- //Emergency pause: the bridge can be paused by the contract owner to halt all deposits and withdrawals in case of security incidents.
- //Timelock on admin changes: relayer address changes require a 2-day timelock, giving users time to exit before any administrative change takes effect.
- //Replay protection: each cross-chain withdrawal is tracked by transaction hash to prevent double-spending.
- //Fee cap: protocol fees are capped at 5% maximum, enforced at the smart contract level.
FUTURE: DECENTRALIZED BRIDGE
The roadmap includes transitioning to a fully decentralized bridge secured by a multi-signature validator set. Bridge validators will stake VTT as collateral, with slashing conditions for malicious or incorrect attestations. Until that transition is complete, the bridge operates under the custodial model described above.
ASSET TOKENIZATION
Vettor is a DLT infrastructure layer for the distribution, trading and governance of regulated financial instruments that represent economic rights over real world assets. The platform is explicitly not a substitute for the regulated vehicles that legally hold the underlying assets, nor for the authorized registrars that maintain the legal ledger of ownership. It is the technical rail that makes distribution, secondary trading and holder governance efficient, transparent and programmable.
THREE-LAYER ARCHITECTURE
The Vettor model separates three distinct layers that must each be built on the right foundations. Blurring them is the primary source of regulatory and operational risk in existing tokenization projects.
- //Layer 1 — Legal ownership: the underlying asset is held by a regulated vehicle (e.g. SPV under Italian Law 130/1999, closed-end real estate AIF, SICAF). The vehicle is the only entity with real rights over the asset and is supervised by the competent authority (Consob / Banca d'Italia in Italy, equivalents abroad).
- //Layer 2 — Economic rights: the vehicle issues financial instruments (notes, units, shares) that give investors defined economic rights — typically a share of rental income, capital gains on disposal, and limited voting rights on extraordinary decisions. The rights are defined in the vehicle's statute, offering documents and subscription agreements.
- //Layer 3 — DLT registry: the financial instruments are registered on a DLT registry maintained by an authorized registrar ("responsabile del registro per la circolazione digitale" in Italy, an entity enrolled with Consob under Law 52/2023 that implemented the EU DLT Pilot Regime). Vettor provides the DLT infrastructure; the registrar provides the legal effect of transfers.
VEHICLE OPTIONS
The first production deployment of Vettor targets Italian jurisdiction and the SPV framework introduced by art. 7.1 of Law 130/1999 (added by the 2019 Decreto Crescita), which specifically enables securitization of proceeds from real estate. This framework is mature, widely used by institutional players, and produces financial instruments (notes) that are natively eligible for DLT registration under Italian Law 52/2023. Alternative vehicles considered for future deployments include closed-end real estate AIFs managed by authorized SGRs and, for smaller operations, Simple Investment Companies (SIS).
REGISTRAR PARTNERSHIP MODEL
In its initial configuration, Vettor operates in partnership with entities already authorized by Consob as registrars for the digital circulation of financial instruments. The partner maintains the legal registry and provides the regulated settlement layer; Vettor provides the chain, the wallet infrastructure, the secondary trading venue, and the on-chain governance tooling. Each legal transfer on the partner's registry is mirrored by a corresponding token transfer on Vettor, preserving 1:1 alignment between on-chain state and legal ownership. This model avoids the multi-year authorization process while delivering regulated transferability from day one.
ON-CHAIN GOVERNANCE
Token holder governance on Vettor mirrors the governance provisions of the underlying legal vehicle. On-chain votes are not the legal source of authority — the vehicle's statute, fund regulation or indenture is — but they are the primary mechanism through which token holders exercise the rights granted to them by those documents. Outcomes are executed off-chain by the vehicle's directors or trustees based on the on-chain result. The protocol supports:
- //Revenue distribution: the vehicle pays out rental income, interest or other proceeds to token holders proportionally. On-chain proposals schedule and authorize distributions consistent with the vehicle's rules.
- //Manager / servicer changes: holders can vote to replace the asset manager or servicer if performance is unsatisfactory. Execution requires supermajority (67%) on-chain and is enforced via the vehicle's governance provisions.
- //Disposition and exit: holders can authorize the sale of the underlying asset or the wind-down of the vehicle. Requires supermajority (67%). On approval, the token is frozen and marked Redeemed; the actual sale is executed by the vehicle's directors following normal legal procedure.
- //Signal proposals: non-binding votes for operational guidance.
COMPLIANCE AND IDENTITY
Vettor integrates identity verification at the application chain level. KYC/AML requirements and any jurisdictional eligibility restrictions (e.g. accredited investor status under applicable securities law) are enforced at the protocol level for regulated actions such as primary subscription, secondary trading of security tokens, and governance participation. Security tokens representing financial instruments are not in scope of MiCA — they fall under the existing financial instruments regime (MiFID II, Prospectus Regulation and the EU DLT Pilot Regime as transposed nationally). The compliance layer is designed to satisfy these requirements together with the regulated registrar partner.
GOVERNANCE
VTT governance operates at two levels: protocol-level governance for the blockchain itself, and asset-level governance for individual tokenized assets.
PROTOCOL GOVERNANCE
VTT stakers can propose and vote on changes to the protocol. Proposal types include parameter changes, treasury spending, protocol upgrades, DEX pause, and chain registration.
PROPOSAL LIFECYCLE
- //Creation: any staker can propose changes (parameter changes, treasury spending, protocol upgrades, DEX pause). Vote weights are captured at the block when the proposal is created (snapshot), preventing vote buying after proposal submission.
- //Voting: 7-day voting period, 33% quorum required, >50% approval threshold.
- //Timelock: passed proposals enter a 24-hour queue before execution, providing a safety window for the community to review outcomes.
- //Execution: after the timelock expires, proposals are executed automatically on-chain.
ASSET GOVERNANCE
Each tokenized asset has independent governance. Holders vote proportionally to their token balance:
- //Revenue distribution proposals: trigger distribution of accumulated revenue to all holders.
- //Issuer change proposals: replace the asset manager/issuer address (67% supermajority).
- //Dispose asset proposals: authorize the SPV to sell the underlying asset, freeze tokens and mark Redeemed (67% supermajority).
- //Signal proposals: non-binding votes for operational guidance.
ROADMAP
The VTT development roadmap follows an iterative approach, with each phase building on the infrastructure delivered in previous phases.
TEAM
The VTT project is led by Alessandro Vettor and a team of blockchain engineers, smart contract developers, and compliance experts. The team brings deep experience in distributed systems, cryptographic protocol design, financial technology, and regulatory frameworks for digital assets.
Development is conducted in the open with regular releases and transparent communication. The codebase is built in Rust for the core protocol and TypeScript for the web platform and SDK.
CONCLUSION
VTT provides a vertically integrated blockchain platform that eliminates the fragmentation, cost, and complexity that have held back real world asset tokenization. By building compliance, trading, bridging, and governance directly into the protocol, VTT enables issuers to tokenize any asset class and gives investors fractional access, instant liquidity, and real governance power over their holdings.
With DPoS consensus delivering 3-second block times with BFT finality, a WASM VM for flexible smart contract logic, a native DEX for immediate trading, and an Ethereum bridge for cross-chain interoperability, Vettor is built to bring real world assets on-chain at scale.
