Polygon Labs' Marc Boiron on Unifying Blockchains

Marc Boiron, CEO of Polygon Labs, speaks with a practiced clarity that reflects his background as a lawyer. Over the course of our conversation, he outlines Polygon's strategy to position itself as the connective tissue in an increasingly crowded blockchain ecosystem. As competition intensifies and market conditions fluctuate, Polygon is betting on a new product called AggLayer to unify the fragmented world of blockchain – a vision that's ambitious, though not without its challenges.
Boiron's path to blockchain leadership followed an unconventional route through legal corridors. A former law firm partner, he served as Chief Legal Officer at dYdX before joining Polygon Labs in a similar capacity, eventually ascending to CEO. He talked about blockchain infrastructure, as the industry confronts questions of interoperability, scalability, and practical utility.
Boiron is a speaker at this year's Consensus festival in Toronto May 14-16.
CoinDesk: Your background is primarily in law rather than technology. Tell me about it?
Boiron: I'm the CEO at Polygon Labs. I've been the CEO for about two years now. Before that, I was the Chief Legal Officer at Polygon Labs for about a year. I joined Polygon after having been the Chief Legal Officer at dYdX for a while. I was frankly just really excited about joining a team that was looking to scale Web3 in the way that Polygon is.
Before being on the Polygon legal team, I was a partner at various big law firms in the U.S., advising on crypto since 2017.
CoinDesk: Polygon describes itself as building an 'Internet of Value.' That's a compelling phrase, but what does it actually mean in concrete terms?
Boiron: From Polygon's perspective, we're trying to build a trustless internet that makes it easily accessible to anyone to do whatever they want whenever they want with their assets. The way that shows up is through a product that we are developing called the AggLayer. The AggLayer is intended to be a form of settlement for every chain across crypto in general.
The Internet of Value contrasts with today's internet, which is primarily the Internet of Information. Web3's fundamental innovation is bringing actual value on-chain. The challenge we face is how to scale this capability across the entire digital ecosystem
Right now the answer is many different blockchains that exist. But if you actually want to have something that feels like the internet of information becoming the internet of value, you need something that brings together all of those chains so that you can get a massive amount of transactions happening across all of these chains, but in a seamless way that feels just like the current internet. So the Internet of Value really gets brought to life through AggLayer.
CoinDesk: Interoperability has been promised by many projects over the years. What technical approach is Polygon taking with AggLayer that you believe will succeed where others have struggled?
Boiron: AggLayer is a product designed to unite all of Web3 on a single settlement layer. Currently, what's missing in the ecosystem is a secure way to move between different chains.
The only effective solution for secure and rapid cross-chain movement is to use a settlement layer like AggLayer. In practice, this means the ability to finalize transactions between two different chains in less than two seconds.
Our model differs from other cross-chain infrastructure in how it handles asset transfers. We monitor all assets moving in and out of chains. When someone initiates an asset transfer out of a chain, we use pessimistic proof to verify and confirm the assets' existence on that chain before allowing the transfer.
Currently, this system works exclusively with Polygon CDK chains. However, we're launching an update soon that will allow any EVM chain to connect to AggLayer. This expansion brings us closer to our vision of unifying all of Web3 through AggLayer.
CoinDesk: Real-World Assets on blockchain have been discussed for years with limited practical implementation. What's your perspective on RWAs, and how do they fit into Polygon's overall approach to the market?
Boiron: One of Polygon's core strengths has always been our relationships with financial institutions, which is crucial for both real-world assets (RWA) and payments.
When it comes to payments, Polygon POS hosts nearly 50 stablecoins. Every major fintech player that operates on other chains is also on Polygon, though many Polygon-based companies operate exclusively on our platform.
For instance, Lemon Cash in Argentina operates exclusively on our platform. Other major payment companies like Stripe process most of their volume through Polygon POS, while companies like Grab in Singapore use Polygon POS alongside other chains.
We've established 18 tokenized funds on Polygon POS, and our strategy focuses on making these assets truly functional. Currently, most tokenized assets across chains remain dormant after creation, offering little advantage over their traditional counterparts.
Our focus is integrating these assets into DeFi, starting with enabling them as collateral in lending pools for borrowing purposes.
CoinDesk: How is Polygon responding to recent market volatility and regulatory developments?
Boiron: From our perspective, we just keep building regardless of what the environment is. We know what it is that we want to build, and we just keep building away at it.
The market reactions obviously impact adoption. Ultimately, the economy ends up impacting the adoption for everything in the world, and it's no different for crypto. The only thing that we can do is keep building away, and as the market turns, being very well-positioned with great products that users want to use.
CoinDesk: Several new blockchains have launched with claims of superior performance metrics. How does Polygon position its original POS chain in this increasingly competitive landscape?
Boiron: I think Polygon POS is already very well-positioned for that. There's a reason why we see payments being adopted on POS — it is because it is actually already fast and low-cost.
The thing with everything that we build, including Polygon POS, is that we're continuing to adapt it. One of the things that's exciting is that we get to see innovations across the space. People get to see how Polygon POS is innovated and adopt some of those things. We get to look at what others are doing and adopt some of their ideas as well as continuing to research and bring in new ideas ourselves.
So I think what you'll end up seeing on POS is a chain that's just as fast or faster than all of the new chains that we're talking about here. The nice thing is that comes along with years of very good security and still maintaining the low costs that currently exist on-chain.

Asia Morning Briefing: BTC Reclaims 100K as Markets Shrug off Iran Strike

Welcome to Asia Morning Briefing, a daily summary of top stories during U.S. hours and an overview of market moves and analysis. For a detailed overview of U.S. markets, see CoinDesk's Crypto Daybook Americas. As Asia begins the trading week, BTC is trading above $100,500 as the initial volatility from news over the weekend that the U.S. struck some of Iran's nuclear facilities begins to subside. While prices briefly dipped below six figures on Sunday in a risk-off reaction, markets have since stabilized. Equity futures are flat, and gold is up only marginally, suggesting that traders are not yet pricing in a broader escalation. The lack of follow-through in traditional markets may reflect expectations that Iran's response will be contained or delayed, rather than immediate and destabilizing. Crude oil is holding its gains near $76 per barrel after spiking nearly 4% Sunday evening on fears that Iran could block the Strait of Hormuz, a key chokepoint for global oil shipments. Still, commentary from U.S. officials and muted early-week trading suggest that investors remain in a wait-and-see mode. In crypto markets, altcoins that had mirrored BTC's weekend drop, like ETH, XRP, and SOL, are also clawing back losses. For now, the market appears to be treating the U.S.-Iran clash as a geopolitical flashpoint, not a structural break. Crypto exchange OKX is considering a public listing in the U.S., according to a report from The Information. Earlier this year, the exchange announced a U.S. expansion after settling with the Department of Justice over accusations that it operated in the country without a money transmitter license. Among other crypto-linked companies, Bullish, a competitor to OKX and the parent company of CoinDesk, is also said to be considering an IPO given investors' appetite for companies with exposure to digital assets. OKX told CoinDesk it had no comment on the matter. Polymarket bettors are cooling to the idea that the U.S will hit Iran a second time before the end of the month. The 'yes' side of a contract asking if the U.S. will conduct another military action on Iran by June 30 is now trading at 54%, from 74% in the hours after the initial strike on Iranian nuclear sites. There appears to be a growing market belief that deconfliction – on both sides – is on the agenda, as evidenced by another contract asking bettors about the likelihood of Iran closing the Strait of Hormuz, which is currently trading at 49% down from 52%. BTC: Bitcoin rebounded to $101,419 after a volatile 4.5% intraday swing, finding strong support at $99,000 amid geopolitical tensions and surging institutional buying interest, according to CoinDesk Research's technical analysis data. ETH: Ethereum fell 2.3% to $2,237 amid U.S.-Iran tensions, breaking a six-week consolidation pattern despite over $500 million in institutional accumulation. Gold: Bank of America analysts predict gold could hit $4,000 an ounce within a year, an 18% jump, driven less by geopolitical tensions and more by mounting U.S. fiscal debt and a global shift by central banks away from the dollar toward gold. Nikkei 225: Asia-Pacific markets fell Monday as the U.S. strikes on Iranian nuclear sites fueled oil price spikes and fears of broader Middle East escalation, with Japan's Nikkei 225 down 0.56%.

Solana's SOL Falls 8% as Traders Brace for Fallout From a Spike in Oil Price

Solana (SOL) SOL is trading at $128.82, down 8.33% in the past 24 hours, after a steep intraday correction linked to rising geopolitical tensions. The token dropped from $140.39 to $127.25, with the sharpest hourly decline occurring at 13:00, when sell pressure spiked and trading volume exceeded 4 million, according to CoinDesk Research's technical analysis model. The market reaction followed confirmed reports of U.S. military strikes targeting Iranian nuclear sites, triggering widespread risk aversion across crypto markets. Some traders now worry that a closure of the Strait of Hormuz, even if temporary, could send oil prices soaring. That would likely stoke inflation, reduce the odds of near-term Fed rate cuts, and prolong the risk-off environment hurting crypto markets. A direct attack on the waterway could intensify the sell-off in altcoins, as bitcoin dominance historically rises during periods of geopolitical turmoil. SOL's decline also marked a break below key technical levels, including the 200-day simple moving average near $149.54. Throughout the session, SOL printed lower highs and struggled to sustain rebounds, pointing to weakening market structure. With elevated volume on red candles and technical indicators flashing bearish, traders are now watching the $120–$125 zone as a potential support area. Technical Analysis Highlights SOL dropped 8.1% from $140.39 to $129.02 during the analysis period, forming an $11.37 decline. The session's widest price range stretched from $141.14 to $126.85, a 10.2% intraday swing. The largest hourly drop occurred at 13:00, with price falling from $133.58 to $128.82 on 4.03M volume. A descending channel developed across the session, with lower highs and lower lows confirming bearish structure. Key resistance formed at $133.80, which capped multiple rebound attempts. Initial support emerged at $127.43, while a new intraday floor formed at $128.90. From 15:25 to 15:27, a volume spike pushed price below $129.30 during a continuation sell-off. Late-session movement showed SOL trading between $130.42 and $128.85 under consistent sell pressure. Several recovery attempts near $130.05 failed as volume increased on each rejection. Significant supply concentration appeared near $130.20, reinforcing short-term bearish momentum.

Bitcoin Rallies Above $102K After Panic Sellers Dump Into War Fears

Bitcoin (BTC) BTC rallied above $102,000 after briefly falling below $101,000 in a volatile session marked by unusually heavy trading, according to CoinDesk Research's technical analysis model. Market participants reacted swiftly to the dip, which pushed BTC near the bottom of its month-long trading range. The reversal gained momentum as volume accelerated, leading to a strong rebound. The move coincided with a sharply worded post from James Lavish, a Managing Partner of the Bitcoin Opportunity Fund, who wrote on X: 'If you are selling Bitcoin because of the possibility of the world going to war, you have absolutely no idea what you own.' The $100K–$110K range has contained price movement for nearly a month. On-chain metrics suggest a balanced market with neither excessive profit-taking nor aggressive accumulation, while derivatives data indicates cautious sentiment with continued demand for downside protection. Technical Analysis Highlights A midnight push lifted BTC above $102,800 with trading volume peaking at 17,906 BTC. Between 05:57 and 06:00, BTC climbed from $102,767 to $102,912, supported by volume spikes over 150 BTC per minute. Peak recovery-period volume hit 184.24 BTC, helping drive price toward $102,990. Minute-level consolidation around $102,680–$102,720 preceded the breakout. A higher support level began forming near $102,870 as volatility decreased.
