Sergey Nazarov does not usually appear on lists of RWA founders. He is not issuing tokenized bonds. He is not running a tokenized fund. He does not have $2 billion in assets under management on-chain. He is building something underneath all of that — and the RWA sector cannot function without it.
Nazarov is the co-founder of Chainlink, the decentralized oracle network that feeds real-world data into blockchain smart contracts. If you want to understand why every major RWA protocol works, understanding what Chainlink does is mandatory. And understanding what Nazarov has built toward — the vision he calls the "Internet of Contracts" — is the most useful framework for understanding where institutional tokenization is headed.
The Problem He Solved
A smart contract can automate payments, enforce rules, and transfer ownership without intermediaries. But it cannot, on its own, know anything about the world outside the blockchain. It cannot check whether the S&P 500 closed above 5,000. It cannot verify that a shipment arrived at its destination. It cannot confirm the current price of gold. It is a closed system.
RWA tokenization requires constant data from the outside world. A tokenized Treasury bill needs to know the current interest rate to calculate yield. A tokenized real estate fund needs a property valuation oracle. A tokenized agricultural commodity needs commodity price feeds. A DeFi protocol using RWA as collateral needs to know the current market value of that collateral to manage liquidation risk. Every one of these data requirements is a problem Chainlink exists to solve.
Chainlink's oracle network aggregates data from multiple independent node operators, uses cryptographic proofs to verify its integrity, and delivers it on-chain in a tamper-resistant format. The key word is decentralized: a centralized price feed is a single point of failure and manipulation. Chainlink's architecture makes manipulation economically impractical at scale.
CCIP: The Cross-Chain Layer That RWA Requires
The oracle problem was Phase 1 of what Nazarov is building. Phase 2 is the Cross-Chain Interoperability Protocol (CCIP) — Chainlink's infrastructure for moving tokenized assets and data across different blockchains.
This matters enormously for RWA. The tokenized asset market is fragmented across dozens of blockchains. BlackRock's BUIDL is on Ethereum, Solana, Polygon, Avalanche, Arbitrum, Optimism, Aptos, and BNB Chain simultaneously. Franklin Templeton's BENJI is on nine blockchains. A tokenized Treasury sitting on Polygon cannot natively interact with a DeFi lending protocol on Ethereum without a bridge — and bridges are historically the most hacked category in blockchain infrastructure.
CCIP is Chainlink's answer: a standardized, audited, institutional-grade cross-chain messaging layer that moves assets and data between blockchains with the same security guarantees as Chainlink's oracle network. When Swift — the global interbank messaging network — announced it was testing tokenized asset settlement across multiple blockchains, it chose Chainlink's CCIP as its infrastructure. That is the single most significant institutional validation CCIP has received.
The Proof of Reserve Problem
One of Chainlink's most directly RWA-relevant products is Proof of Reserve — automated, on-chain verification that a tokenized asset is actually backed by what the issuer claims. When PAXG claims each token is backed by one troy ounce of physical gold in a vault, Chainlink's Proof of Reserve service creates an automated, cryptographically verifiable audit of that claim — not a periodic manual attestation, but a continuous on-chain proof.
For the RWA sector, this is the trust layer that institutional investors require. The difference between "we have an audit" and "the chain can verify this continuously" is the difference between TradFi trust infrastructure and on-chain trust infrastructure. Nazarov has consistently framed this as the foundation for institutional adoption: you cannot get large capital allocators to use on-chain assets if the verification of those assets depends on trusting an issuer's word.
What "Internet of Contracts" Actually Means
Nazarov's long-horizon thesis is that all financial contracts will eventually be able to connect to, communicate with, and settle against each other automatically — regardless of what system they live in. A bank's traditional securities system will be able to settle a tokenized bond held in a DeFi protocol. An insurance contract will automatically pay out when an oracle verifies a covered event. A supply chain payment will release automatically when blockchain-verified delivery data confirms receipt.
This is not a distant concept. Chainlink's CCIP is already being used in production by SWIFT, Fidelity, and major European financial institutions. The Swift pilot moved tokenized assets between multiple banks across blockchains using CCIP as the interoperability layer — a proof of concept for exactly the cross-institution, cross-chain settlement that the RWA sector needs to scale beyond siloed products into interconnected financial infrastructure.
Why Nazarov Belongs on This List
The Top Voices in RWA series covers the people shaping how real-world assets move on-chain. Most are asset managers or issuers — they are building the products. Nazarov is building the infrastructure underneath the products. Without reliable price feeds, cross-chain interoperability, and on-chain verification, tokenized assets cannot function in institutional contexts. Chainlink's technology is present in virtually every major RWA protocol operating today.
That quiet ubiquity is precisely why Nazarov deserves more attention in RWA conversations. The people building the visible products get the headlines. The people building the infrastructure they depend on tend to be overlooked until the infrastructure fails. With Chainlink, it hasn't failed. That non-event is the most important thing to understand about Nazarov's contribution to the sector.
