Decentralized OTC & Secondary Market for Tokenized RWAs
Decentralized OTC (dOTC) is a permissioned, peer-to-peer secondary market for tokenized RWAs where holders can exit positions on-chain with wallet-to-wallet settlement and no central asset pool to attack. It is the compliant secondary venue large RWA flows cannot find on public DEXes.
Protofire builds decentralized OTC and secondary-market infrastructure for tokenized real-world assets, productized as dOTC, our decentralized OTC venue, live on Polygon and BNB Chain. A secondary market for tokenized RWAs is where holders of tokenized stocks, bonds, commodities, ETF shares, and private credit exit and trade their positions: they buy and sell directly with each other, on-chain, instead of routing through a public DEX or an off-chain broker desk.
dOTC is that RWA secondary-liquidity layer, the place where a tokenized asset meets the capital that wants to trade it, with on-chain settlement and permissioning enforced at the venue. It is a production product Protofire built and runs: it operates today as the secondary market for Swarm Markets' tokenized RWAs, and we deploy the same infrastructure for EVM chains, RWA tokenizers, and RWA issuers who need a compliant venue where their assets can be exited and priced. It ships with an embeddable, AI-discoverable widget and an optional yield toolset that pays liquidity providers to keep the market open.
The problem it solves is specific: RWA trading volume on-chain stays low when there is no transparent, compliant place to sell. Listing on a CEX or running your own DEX is expensive, and a public DEX exposes large RWA flows to slippage, signaling, and MEV. dOTC is the inexpensive alternative: a venue where the asset meets liquidity, holders can see real bid/ask depth, and LPs earn a predictable reward for providing it.

What we deploy
A dOTC is a permissioned, peer-to-peer trading venue with on-chain settlement. It is not a centralized order book that custodies everyone's assets, and not a fully discretionary off-chain broker desk. Participants make and take offers directly; the contracts handle matching and settlement; permissioning and KYC gating are enforced at the access layer.
Because trades settle wallet-to-wallet, the venue never aggregates user RWAs into a single pool, so there's no honeypot of deposited assets for an attacker to target, which is one of the reasons large holders and institutions prefer controlled private execution to a public AMM. The point is controlled, on-chain, permissioned execution for trades that are too large, too sensitive, or too regulated for a public venue, with the transparency and self-custody that a phone-and-email OTC desk can't offer. Benefits: on-chain settlement with no central asset pool to attack · permissioned, KYC-gated access · private execution without giving up self-custody.
The mechanics are designed to keep a live, two-sided market open. A holder buys a selected RWA by taking an existing offer or posting their own bid; to sell, they create an active offer priced within ±0-20% of a dynamic market reference price, and offers must stay live for a minimum duration per epoch so the book doesn't evaporate.
The optional yield toolset is what attracts liquidity: holders and market makers who keep active bid/ask offers on the dOTC earn weekly rewards, paid in the Swarm Markets deployment in the SMT reward token, sized to stay competitive with on-chain yield depending on the RWA. Holders can also capture dividends the underlying RWA distributes during the holding window, plus spread and price movement.
Minimum starting amount is 100,000 USDC and an offer takes about five minutes to create. Benefits: a predictable, competitive reward that pulls LPs and market makers in · a continuously quoted, two-sided market instead of a dead order book · visible bid/ask depth and trade history per RWA for real decision-making.
dOTC is delivered as a customizable UI plus an embeddable widget that drops into an issuer's or tokenizer's own web page, so the secondary market lives where investors already are, not behind a separate app. The widget is built to be discoverable by AI: its market data (the live bid/ask, volumes, and trade counts per RWA) is structured so that AI search engines and agents can surface a tokenized asset's real secondary market when a prospective buyer asks where and at what price they can trade it.
For an issuer competing for crypto-native capital, being the answer an AI assistant returns, with a live, quotable market attached, is a distribution channel that a closed CEX listing or an off-chain desk simply doesn't have. Benefits: the market embeds where your investors already are · AI-discoverable so your RWA surfaces in AI search and agent flows · a quotable, public price and depth signal instead of an opaque desk.
We didn't theorize this venue. We built the permissionless decentralized OTC inside Swarm Markets, the world's first BaFin-licensed DEX for crypto and tokenized real-world assets. There we delivered the dOTC for institutional block trades, with private offers and configurable order parameters, alongside KYC, multi-tier permissioning, and 50+ pairs including tokenized Apple and Tesla stock, as part of an engagement that cut fees 98%, onboarded 7,000+ verified users, and lifted monthly volume from under $1M to over $15M in six months.
That production system is now the RWA dOTC: live across Polygon and BNB Chain, with 50+ tokenized RWAs available, payable rewards in SMT, and the same compliant rails ready to deploy on a new chain or issuer's stack. Benefits: shipped in a BaFin-licensed venue, not a prototype · the exact stack is redeployable for your chain or assets · a real reference an allocator can diligence.
dOTC fits three buyers. EVM chains building for RWAs (tokenized stocks, bonds, commodities, ETFs, private credit) that have RWA TVL on-chain but few transactions, and need a secondary venue plus a yield program to grow trades and attract LPs without building the stack from scratch. RWA tokenizers (such as Swarm Markets) that issue tokens representing real assets and need a compliant place for holders to exit. RWA issuers (ETFs, tokenized funds, private credit, non-publicly-traded equity) that want to attract crypto-native investors and need a visible secondary market before those investors will commit. The common pattern is significant RWA TVL but no OTC venue, no P2P secondary market, and no yield to reward the holders who would make one. Benefits: a secondary venue without a from-scratch internal build · a yield program that converts idle RWA TVL into traded volume · a compliant exit path that makes the primary offering easier to sell.
dOTC runs in production today on Polygon and BNB Chain, EVM networks where RWA tokenizers already issue assets. In the Swarm Markets deployment it covers 50+ tokenized RWAs, including AAPL, TSLA, NVDA, and tokenized T-Bonds, with rewards paid in the SMT token. To trade RWAs on the dOTC itself, no KYC/KYB is required at the venue; KYC/KYB applies when a holder wants to directly redeem the underlying real asset on the primary Swarm Markets platform, which triggers the broker to sell the actual security.
Deploying for a new client needs only an EVM-compatible chain, an RWA token issued on it, a web page for the embeddable widget, and a KYC provider integration where redemption requires one. Benefits: live on two production EVM networks, not a testnet · 50+ tradable tokenized RWAs as a working reference · a thin integration surface: your chain, your token, your page.

The team that ships RWA secondary infrastructure
Protofire is a blockchain engineering company with 250+ shipped projects across 60+ networks and 95+ protocols since 2016. dOTC is part of an RWA finance stack we built and run, alongside RWArmor (parametric protection for tokenized RWAs), VaultOS (client-owned vault infrastructure), and Arenas (white-label credit), so the secondary market we deploy is one we operate, not a reference design. We built the permissionless dOTC inside Swarm Markets, the first BaFin-licensed DEX for tokenized RWAs, and we maintain Solhint, the Solidity linter used by 1M+ developers.
We're also an official Safe Guardian, with Safe securing $2B+ across 120+ EVM networks, the kind of permissioned, institution-grade rails dOTC is built on. Our Swarm Markets engagement is the proof point: building that dOTC cut fees 98%, onboarded 7,000+ verified users, and lifted monthly volume from under $1M to over $15M in six months.
“A compliant, AI-discoverable RWA secondary market that pays LPs to provide liquidity, not a public DEX, not an off-chain broker desk.”
