RWA Tokenization Infrastructure
RWA tokenization infrastructure: permissioned tokens, async vaults, compliance, Proof-of-Reserve, and secondary liquidity deployed on your own stack, not a closed platform.
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.
Permissioned Token (ERC-3643)
Async Vault (ERC-4626/7540)
Compliance & KYC
Oracles & Proof-of-Reserve
Secondary Liquidity (dOTC)
Parametric Protection (RWArmor)
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.
Once an asset is tokenized, capital has to flow in and out of it. We build vaults on ERC-4626, and on ERC-7540 for the asynchronous subscription/redemption that funds and credit pools actually need: request, settle, and NAV-gate flows that public vaults and manual scripts can't do at institutional quality.
This is the layer our VaultOS product hardens into client-owned, policy-driven vault infrastructure (separate roles for operator, valuation, risk, and admin); validated in design partnerships with AP3X and other tokenization platforms. For the productized vault, see VaultOS; this page builds the broader category. Benefits: async subscribe/redeem for real funds · standardized, composable vault interface · governance and role separation institutions require.
The blocker for institutional RWAs is rarely the token itself; it's KYC/KYB, eligibility, and the audit trail. We integrate KYC/KYB providers, encode investor eligibility and jurisdiction logic into the transfer layer, and run the contracts through pre-audit hardening. We maintain Solhint, the open-source Solidity linter used by 1M+ developers and built with Ethereum Foundation grants, and our published audit reports are public proof of the bar. Benefits: KYC/transfer enforcement at every transfer · a defensible compliance trail for regulators and allocators · audited contracts before a single asset is minted.
A tokenized asset is only as trustworthy as the proof that the real asset exists and is worth what the token says. This is where a lot of RWA projects quietly break: the token claims it's backed, but nothing on-chain actually attests to it. We're core contributors to Chainlink and have been a Chainlink partner since 2021, and we wire in Chainlink Proof-of-Reserve so the off-chain collateral behind your token (treasuries in custody, fiat reserves, physical assets, loan books) is attested on-chain, continuously and independently, instead of asserted in a quarterly PDF.
Alongside it we integrate price and NAV oracle feeds (from Chainlink or DIA, across 7+ networks) so valuation updates automatically and your redemptions, mint caps, and vault accounting all read from the same trusted source. For an issuer raising institutional capital, that verifiable reserve-and-valuation layer is often the difference between a pilot and a real allocation. Benefits: independent on-chain attestation of backing assets via Chainlink Proof-of-Reserve · live NAV and collateral transparency, not quarterly PDFs · the reserve story that unlocks institutional capital.
Issuance is the easy half; an asset nobody can exit, or that has no safety net, won't attract institutional money. We stand up secondary venues with dOTC, our permissioned, KYC-gated RWA OTC market (live in production on Polygon and BNB Chain) with a yield toolset to attract liquidity providers.
And we close the gap with RWArmor, our live parametric protection layer for tokenized RWAs: automated, oracle-triggered coverage for redemption freezes, custody breaks, and NAV deviation, built on Atomica and live with LandX. Benefits: compliant secondary liquidity on top of primary issuance · a parametric safety net for LP and institutional capital · the risk infrastructure that converts uncertain RWA yield into protected yield.
Some clients don't want to tokenize a single asset; they want to offer tokenization as their own product to their own customers. We assemble the full stack (ERC-3643 issuance, ERC-4626/7540 vaults, compliance, Proof-of-Reserve, and a secondary venue) into a white-label tokenization platform that runs under your brand, on your infrastructure, under your governance.
It's the same approach behind Arenas, our white-label credit infrastructure live as the LandX Credit Gateway on Arbitrum: your product and your customers, our engineering underneath. 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. Benefits: tokenization-as-a-product under your own brand · the full issuance-to-secondary stack, not one rented component · you own the contracts, the data, and the roadmap, with no platform lock-in.

What clients build with us
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.”
