RWA tokenization infrastructure is the on-chain stack that turns a real-world asset (a treasury bill, a private-credit note, a building, a fund share) into a compliant, transferable token and then governs it for its whole life: issuance, KYC and transfer rules, valuation and Proof-of-Reserve, distribution, secondary liquidity, and downside protection. Most vendors sell you a closed tokenization platform and ask you to move your assets onto theirs; Protofire doesn't.

We are a blockchain engineering company that has shipped 250+ projects since 2016, and we build tokenization infrastructure as an integrator. Rather than lock you into someone else's platform, we deploy the open standards (ERC-3643 for permissioned tokens, ERC-4626 and ERC-7540 for vaults) on your chain and your stack, then add the compliance, oracle, and protection layers around them.

We've also built the on-chain finance stack ourselves: Arenas (white-label credit), RWArmor (parametric RWA protection), VaultOS (private vault infrastructure), and dOTC (RWA secondary market). The infrastructure we hand you is infrastructure we run in production, not a reference architecture.

RWA tokenization is a six-layer stack

A tokenized asset is not one contract. We build and integrate all six layers.

01

Permissioned Token (ERC-3643)

On-chain identity registry and modular transfer rules that enforce KYC eligibility at every transfer, not just at mint.
02

Async Vault (ERC-4626/7540)

Deposit and redemption infrastructure with NAV-gating and async settlement for funds, credit pools, and institutional flows.
03

Compliance & KYC

KYC/KYB provider integration, jurisdiction logic, accreditation checks, lock-ups, and a full audit trail encoded in the transfer layer.
04

Oracles & Proof-of-Reserve

Chainlink price and NAV feeds plus Proof-of-Reserve attestation so valuation and backing are verified on-chain, not asserted in a PDF.
05

Secondary Liquidity (dOTC)

A permissioned, KYC-gated OTC venue with a yield toolset for liquidity providers, so tokenized assets have an exit market.
06

Parametric Protection (RWArmor)

Automated, oracle-triggered coverage for redemption freezes, custody breaks, and NAV deviation, converting uncertain RWA yield into protected yield.

Where we build

Tokenized securities can't trade like an ERC-20: only eligible, verified wallets may hold them, and that has to be enforced on-chain forever, not at mint alone. We issue permissioned tokens on the ERC-3643 standard, with an on-chain identity registry, modular transfer rules (jurisdiction, accreditation, lock-ups, holder caps), and an agent/issuer role model so your transfer agent keeps control after distribution.

The same approach covers tokenized treasuries, private credit, funds, commodities, and real estate. Benefits: compliant by construction, not bolted on · transfer eligibility enforced at the token level · a standard buyers and exchanges already recognize.

How it works

1

Discovery & Asset Structuring

We map the asset, the jurisdictions, the investor base, and the chain, and pick the standard mix (ERC-3643 token, ERC-4626/7540 vault). Deliverable: a tokenization architecture and standards decision record.
2

Issuance & Compliance Build

We deploy the permissioned token, identity registry, transfer rules, and KYC/KYB integration on your stack, pre-audited. Deliverable: live, audited issuance and compliance contracts.
3

Vaults, Oracles & Proof-of-Reserve

We add the vault layer, NAV/price oracles, and Chainlink Proof-of-Reserve. Deliverable: a deposit/redeem vault with on-chain reserve attestation.
4

Distribution & Secondary

We connect distribution and stand up a secondary venue (dOTC) so holders can enter and exit compliantly. Deliverable: a permissioned secondary market and LP yield toolset.
5

Protection & Ops (Optional)

We add RWArmor parametric coverage and the monitoring/governance rails to run it. Deliverable: live protection coverage plus Safe-governed operational controls.

The builder behind the RWA finance stack

Protofire is a blockchain engineering company with 250+ shipped projects across 60+ networks and 95+ protocols since 2016. What sets our tokenization work apart is that we've built the on-chain RWA finance stack ourselves: Arenas (white-label credit, live as the LandX Credit Gateway on Arbitrum), RWArmor (parametric protection for tokenized RWAs), VaultOS (client-owned ERC-4626/7540 vault infrastructure), and dOTC (RWA secondary market, live on Polygon and BNB Chain).

Our credentials include maintaining Solhint (the Solidity linter used by 1M+ developers) and serving as an official Safe Guardian. Clients include Swarm Markets, Chainlink, Aave, MakerDAO, Filecoin, and the Ethereum Foundation. We're also a top-3 indexer in The Graph ecosystem and a Chainlink core contributor, and as a Safe Guardian, Protofire-deployed networks secure $2B+ in assets across 120+ EVM networks. The compliance, oracle, and reserve layers we wrap around a tokenized asset therefore run on infrastructure we operate ourselves.

The proof is in shipped systems, not slideware. For Swarm Markets we helped build the world's first BaFin-licensed DEX for crypto and tokenized real-world assets (KYC, multi-tier permissioning, and 50+ pairs including tokenized Apple and Tesla stock), cutting fees 98%, onboarding 7,000+ verified users, and lifting monthly volume from under $1M to over $15M in six months. When we recommend a tokenization architecture, it's one we already operate.

You own the contracts, the data, and the roadmap, not a third-party platform.

FAQ

What is RWA tokenization?
RWA (real-world asset) tokenization is the process of issuing a blockchain token that represents a real asset (a treasury bill, private-credit note, building, commodity, or fund share) and enforcing ownership, eligibility, and transfer rules for it on-chain. Done properly, it covers far more than minting a token; it is a full lifecycle: compliant issuance, KYC and transfer restrictions, valuation and Proof-of-Reserve, distribution, secondary liquidity, and downside protection. A tokenized security can't trade like an ERC-20, because only eligible, verified wallets may hold it, and that has to be enforced on-chain forever, not at mint alone. Protofire builds that whole stack on open standards (ERC-3643 for permissioned tokens, ERC-4626 and ERC-7540 for vaults) on your own infrastructure rather than a closed platform, then wraps the compliance, oracle, Proof-of-Reserve, secondary-liquidity, and protection layers around it.
What's the difference between tokenization and securitization?
Securitization is a financial and legal process: pooling assets (mortgages, loans, receivables) into a new security with its own cash-flow structure and legal wrapper. Tokenization is the on-chain representation step: issuing a blockchain token that stands for ownership of an asset (which might be a security, a fund share, a treasury bill, or a building) and enforcing eligibility and transfer rules for it on-chain, for the whole life of the token. They're complementary, not competing: you can tokenize an instrument that's already been securitized, or tokenize a single asset that was never securitized at all. Protofire builds the tokenization and lifecycle infrastructure (permissioned issuance, vaults, compliance, Proof-of-Reserve, and secondary liquidity), while the securitization and legal structuring is handled by your counsel and structuring partners, and we integrate our contracts with it rather than replacing it.
Which token standard should I use: ERC-3643 vs. others?
For tokenized securities that only eligible, verified holders may own, ERC-3643 (the permissioned-token standard) is the usual choice. It enforces identity and transfer rules at the token level through an on-chain identity registry, modular transfer rules (jurisdiction, accreditation, lock-ups, holder caps), and an agent/issuer role model, so your transfer agent keeps control after distribution. ERC-20 suits freely transferable utility tokens. For the vault that takes deposits against the asset, ERC-4626 is the standard, and ERC-7540 adds the asynchronous subscribe/redeem (request, settle, and NAV-gate flows) that funds and credit pools actually need and that public vaults can't do at institutional quality. Most real deployments combine an ERC-3643 token with an ERC-4626/7540 vault. We pick the mix with you during structuring, mapping the asset, jurisdictions, and investor base, not after the contracts are written.
How are custody and compliance handled?
We don't take custody. We deploy on your stack and integrate your custodian or MPC arrangement, your KYC/KYB provider, and your transfer-agent logic, so eligibility and jurisdiction rules are enforced at every transfer (not at mint alone) and the audit trail lives on-chain. Investor eligibility and jurisdiction logic are encoded directly into the ERC-3643 transfer layer, with modular rules for accreditation, lock-ups, and holder caps. Reserves and NAV are attested via Chainlink Proof-of-Reserve and price oracles, so the backing assets behind the token are verified on-chain continuously and independently rather than asserted in a quarterly PDF. Contracts are hardened through pre-audit and run against Solhint (the Solidity linter we maintain, used by 1M+ developers) before any asset is minted, and our published audit reports are public proof of the bar we hold contracts to.
Do you build a closed platform, or on our own stack?
On your own stack. The wedge against closed tokenization platforms (Tokeny, Securitize, Zoniqx) is that we're a builder/integrator, not a platform you rent: you own the contracts, the chain, the data, and the roadmap. We deploy the open standards (ERC-3643 permissioned tokens, ERC-4626/7540 vaults) and wrap our own production components around them: VaultOS for client-owned vault infrastructure, dOTC for a permissioned secondary venue, RWArmor for parametric protection, and Arenas for white-label credit. There's no revenue share to a third-party platform, no dependence on someone else's roadmap, and no migration the day you want to change something. It's the same approach behind Arenas, live as the LandX Credit Gateway on Arbitrum: your product and your customers, our engineering underneath. The result is tokenization infrastructure you fully own (the contracts, the data, and the roadmap) rather than a rented component on someone else's platform.
We're an asset manager or fund. Can you tokenize a fund share class for us?
Yes. That's a core use case: an ERC-3643 permissioned share token with investor eligibility, jurisdiction logic, and lock-ups; an ERC-7540 vault for the asynchronous subscriptions and redemptions that funds and credit pools actually need (request, settle, and NAV-gate flows); NAV and price oracle feeds plus Chainlink Proof-of-Reserve so valuation and backing are attested on-chain continuously; and Safe-governed operational controls with separate roles for operator, valuation, risk, and admin. Because we deploy on your own stack rather than a closed platform, you keep the contracts, the data, and the transfer-agent control after distribution, and there's no migration if you change managers or chains later. We validated this vault approach in design partnerships with AP3X and other tokenization platforms. For the productized vault layer specifically, this routes to our VaultOS product, while this page builds the broader category.
How long does an RWA tokenization project take?
It depends on how much of the lifecycle you need. A focused ERC-3643 issuance build (permissioned token, on-chain identity registry, modular transfer rules, and KYC/KYB integration) typically runs about 6-10 weeks. A full stack (issuance plus an ERC-4626/7540 vault plus a secondary venue and Chainlink Proof-of-Reserve) typically runs about 16-24 weeks. These are typical ranges, not quotes: the real timeline depends on your asset class, the jurisdictions involved, how many KYC, custody, and oracle integrations are required, and whether the parametric-protection and white-label layers are also in scope. Because we deploy on your own stack as an integrator rather than migrating you onto a closed platform, the work scales to exactly the lifecycle stages you need. We scope it precisely on the first call, once we've mapped the asset, the jurisdictions, the investor base, and the chain.
How much does an engagement cost?
It's scoped to the asset class, the compliance surface, and how much of the lifecycle you need. A focused issuance-and-compliance build is sized very differently from a full issuance-plus-vault-plus-secondary-plus-protection stack. Rather than publish a rate card, we map the asset, the jurisdictions, the investor base, and the chain on the first call, then give you a fixed scope and a written estimate before any work starts. Because we deploy on your own stack as an integrator and assemble open standards plus our own production components (VaultOS, dOTC, RWArmor, Arenas), you only pay to build the lifecycle stages you actually need, with no revenue share to a third-party platform and no lock-in. You own the contracts, the data, and the roadmap, so there's no recurring platform fee or migration cost down the line. We size the work to the decisions you need to get right.
