Polygon (formerly Matic Network) is a leading Ethereum scaling ecosystem, providing a suite of Layer 2 solutions, sidechains, and zero-knowledge (ZK) technologies designed to make Ethereum faster, cheaper, and more accessible. Co-founded in 2017 by Jaynti Kanani, Sandeep Nailwal, and Anurag Arjun, with Mihailo Bjelic joining as a co-founder soon after, Polygon initially launched as a Plasma based sidechain with proof of stake consensus (Polygon PoS), a commit chain that periodically checkpoints to Ethereum for security.
This original Polygon PoS chain became enormously popular due to extremely low fees, typically a fraction of a cent per transaction, and full EVM compatibility, attracting major DeFi protocols (Aave, Uniswap, Curve), NFT projects, gaming platforms, and partnerships with global brands including Starbucks, Nike, Reddit, and Disney. Polygon has since evolved into a broader scaling platform built around several products: Polygon PoS, still the most widely used chain in the ecosystem, Polygon CDK (Chain Development Kit, for building custom ZK powered L2 chains), and Polygon AggLayer (an aggregation layer connecting Polygon chains, and increasingly outside chains too, into a more unified network). The standalone Polygon zkEVM product, once positioned as the company’s flagship ZK rollup, has since been folded into this broader strategy and is being sunset as an independent chain, with its sequencer winding down around mid-2026 as the company consolidates its ZK efforts around CDK and AggLayer instead.
The “Polygon 2.0” vision reimagines the ecosystem as a network of interconnected chains unified by AggLayer, with the native token having fully transitioned from MATIC to POL as a multi-chain staking and gas token. Polygon has raised several hundred million dollars over its history, acquired ZK technology teams including Hermez and Mir Protocol, and maintains one of the largest rosters of corporate and institutional partnerships of any Ethereum scaling ecosystem.
How Did Polygon Originate and Evolve?
2017: Matic Network is founded by Kanani, Nailwal, and Arjun in India.
2019: The MATIC token launches via a Binance Launchpad IEO, and testnet development continues.
February 2021: The project rebrands to “Polygon,” and its vision expands from a single sidechain to a broader multi-chain scaling ecosystem.
2021: Explosive growth follows. Aave, Uniswap, and Curve deploy on Polygon PoS, and Reddit, Disney, and Starbucks announce partnerships. Polygon acquires Hermez, a ZK rollup team, in August, and Mir Protocol, a ZK proving team, in December.
March 2023: Polygon zkEVM launches on mainnet as a fully EVM equivalent ZK rollup, at the time positioned as Polygon’s flagship long term scaling technology.
2023: The Polygon 2.0 vision is announced, along with plans for the MATIC to POL token migration.
2024: Polygon CDK launches, giving developers a toolkit to build custom ZK powered chains, and AggLayer development advances significantly.
September 2024 to September 2025: The MATIC to POL migration rolls out in phases. POL becomes the native gas and staking token for Polygon PoS starting in September 2024, and by September 2025 the migration reaches roughly 99% completion, with native POL staking on Ethereum going live alongside it.
2025 to 2026: Polygon shifts its ZK strategy. Rather than continuing to develop the standalone Polygon zkEVM chain as its primary ZK product, the company focuses on Polygon CDK as the toolkit for new chains and AggLayer as the unifying settlement and interoperability layer connecting them. Polygon zkEVM’s sunset is announced, with its sequencer scheduled to stop around July 2026, while Polygon PoS itself is unaffected and continues operating normally.
Early to mid-2026: AggLayer goes live and connects over 190 Polygon CDK built appchains, with an AggLayer Breakout Program offering token incentives to projects, including Katana, Billions, and Miden, that connect their chains to it. Polygon PoS sets a new quarterly record of roughly 743 million transactions in the second quarter of 2026, up about 160% year over year, and cumulative stablecoin transfer volume across the network passes $2.4 trillion. In April 2026, Visa adds Polygon to its global stablecoin settlement program, a significant real world payments milestone for the network.
“Polygon’s mission is to bring the next billion users to Ethereum. We do this by making it fast, cheap, and easy, while keeping Ethereum’s security and decentralization.”
How Can You Explain Polygon in Simple Terms?
Ethereum’s biggest helper: Polygon makes Ethereum usable for everyday transactions by processing them on its own chain at a fraction of the cost, same dApps, same tokens, just far cheaper to use.
Started as a sidechain: Polygon PoS is a separate chain with its own validators that periodically “checkpoints” to Ethereum. It’s not a pure rollup, since it has its own security model, but it’s extremely fast and cheap, and it remains Polygon’s most widely used product.
Betting on ZK, but through a different path than expected: Polygon has spent years investing heavily in zero knowledge technology. Its original approach was a single flagship ZK rollup, Polygon zkEVM, but by 2026 the company shifted that bet toward a broader strategy: Polygon CDK lets other teams spin up their own ZK powered chains, and AggLayer stitches all of those chains together into something that feels more like one unified network. The standalone zkEVM chain itself is being wound down as part of this shift.
Brand and payments partnerships: Polygon has one of the largest rosters of partnerships with traditional brands and payment companies of any blockchain, including Starbucks, Nike, Reddit, Disney, and, as of April 2026, Visa’s global stablecoin settlement program. This makes it a significant gateway for mainstream, real world adoption.
Polygon 2.0 vision: the ecosystem is increasingly a network of interconnected chains, each potentially customized for specific use cases, connected through AggLayer and unified by the POL token, rather than a single monolithic chain trying to do everything itself.
How Does Polygon’s Product Suite Work?
| Product | Type | Typical Transaction Cost | Security Model | Status in 2026 |
|---|---|---|---|---|
| Polygon PoS | PoS sidechain | Roughly $0.01 or less | Own validators plus Ethereum checkpoints | Live, and still the most used Polygon chain |
| Polygon zkEVM | ZK rollup | Roughly $0.05 to $0.20 | Ethereum L1 (validity proofs) | Being sunset, with the sequencer scheduled to stop around July 2026 |
| Polygon CDK | Chain builder kit | Configurable per chain | Customizable ZK security | Live, and now the primary path for new ZK powered Polygon chains |
| AggLayer | Aggregation layer | Not applicable directly | Unified ZK verification across connected chains | Live, connecting over 190 CDK built appchains |
What Are Some Real World Examples of Polygon in Use?
Reddit Collectible Avatars
Scenario: Reddit wanted to bring millions of mainstream users into NFT ownership without requiring them to understand blockchain mechanics.
Implementation: Reddit launched NFT avatars on Polygon PoS, integrated directly into the existing Reddit user experience.
Outcome: Millions of Reddit users were onboarded to blockchain based ownership largely without realizing it, becoming one of the most cited examples of low friction, mainstream Web3 adoption.
Starbucks Odyssey
Scenario: Starbucks wanted to extend its loyalty program with a Web3 layer without alienating its mainstream customer base.
Implementation: Starbucks built its Odyssey loyalty experience on Polygon, issuing coffee related rewards as NFTs.
Outcome: The program became a widely referenced example of a major consumer brand integrating crypto infrastructure directly into an existing loyalty program, even as the standalone Odyssey program was later wound down as Starbucks shifted its broader loyalty strategy.
Visa’s Stablecoin Settlement Program
Scenario: Visa wanted to expand its stablecoin settlement capabilities across additional blockchain networks to support faster, cheaper cross-border settlement for partner banks and merchants.
Implementation: In April 2026, Visa added Polygon to its global stablecoin settlement program, connecting Polygon’s low cost, high throughput infrastructure to Visa’s existing payments network.
Outcome: The partnership gave Polygon one of its most significant traditional finance validation points to date, reinforcing the network’s positioning around real world payments and stablecoin infrastructure alongside its existing DeFi and consumer brand use cases.
Aave on Polygon
Scenario: DeFi users wanted access to Aave’s lending and borrowing markets without paying Ethereum mainnet gas fees for every transaction.
Implementation: Aave deployed lending markets directly on Polygon PoS, alongside its Ethereum mainnet deployment.
Outcome: Polygon’s Aave deployment has processed billions of dollars in cumulative activity, with lending and borrowing available at a small fraction of the cost of doing the same activity on Ethereum mainnet.
What Are the Advantages of Polygon?
Polygon PoS offers ultra low transaction fees, typically a fraction of a cent, making it practical for high frequency, everyday use cases in a way Ethereum mainnet often isn’t. Full EVM compatibility means Polygon works seamlessly with the existing tools, wallets, and smart contracts developers already use on Ethereum. The ecosystem is genuinely massive, with hundreds of active dApps and more corporate and payments partnerships than most competing scaling ecosystems. Polygon has also built real ZK technology depth over the years, acquiring strong teams and now channeling that expertise into CDK and AggLayer rather than a single product. And mainstream brand and payments adoption, from Starbucks and Reddit to Visa’s 2026 stablecoin settlement partnership, continues to validate the technology well beyond crypto native use cases.
What Are the Disadvantages and Risks of Polygon?
Polygon PoS centralization is a real consideration, since the chain runs with roughly 100 validators, a much smaller and less decentralized set than Ethereum’s own validator base. Sidechain security follows from this: Polygon PoS does not inherit Ethereum’s full security guarantees the way a true rollup does, since it relies on its own validator set rather than Ethereum consensus directly. The zkEVM sunset itself is a risk worth naming: any application or user still relying on the standalone Polygon zkEVM chain needs to plan a migration path well before the sequencer stops, since the earlier framing of zkEVM as Polygon’s permanent flagship product turned out not to hold. Competition remains intense, with Arbitrum, Optimism, Base, and other scaling ecosystems all competing for the same developers and users. And complexity persists across the product suite, since understanding the differences between PoS, CDK built chains, and AggLayer still requires more context than a single, simple chain would.
How Do You Manage Risk When Using Polygon?
Understand the security difference between Polygon PoS, which is a sidechain with its own validator set, and any ZK powered chain built on Polygon CDK, which can inherit stronger, Ethereum anchored security guarantees depending on its specific configuration. If you have funds or an application still on the standalone Polygon zkEVM chain, plan your migration well ahead of the scheduled sequencer sunset rather than waiting until the last moment. Monitor how the POL token’s staking and AggLayer related utility continues to evolve, since Polygon’s tokenomics have changed substantially since the MATIC to POL migration completed. Don’t confuse Polygon’s low fees with lower overall risk; ordinary smart contract and protocol risks still apply regardless of how cheap a given transaction is. Bridge funds through Polygon’s official bridge tooling where possible, and be cautious with third party bridges, which have historically been a common target for exploits across the broader multi-chain ecosystem.
Frequently Asked Questions About Polygon
Is Polygon a Layer 2 or a sidechain? Both, depending on which product you mean. Polygon PoS, the original and still most used chain, is technically a sidechain or commit chain with its own validators that periodically checkpoints to Ethereum. Chains built with Polygon CDK and connected through AggLayer can offer stronger, more rollup like security guarantees depending on their configuration. Polygon as a company now offers a broader product suite spanning both categories rather than a single chain.
What happened to Polygon zkEVM? Polygon zkEVM launched in March 2023 as a fully EVM equivalent ZK rollup and was originally positioned as Polygon’s flagship long term scaling product. By 2025 to 2026, Polygon shifted its ZK strategy toward Polygon CDK, which lets other teams build their own ZK powered chains, and AggLayer, which connects those chains together. As part of that shift, the standalone Polygon zkEVM chain is being sunset, with its sequencer scheduled to stop around July 2026. Polygon PoS is unaffected by this change and continues operating normally.
What is the MATIC to POL migration, and is it complete? Polygon upgraded its native token from MATIC to POL as part of the Polygon 2.0 vision, with POL designed as a multi-chain staking and utility token that can eventually support staking, proof generation, and other roles across the wider Polygon and AggLayer ecosystem. The migration rolled out starting in September 2024 and reached roughly 99% completion by September 2025, with native POL staking on Ethereum live since that point. A migration tool remains available for any holders who have not yet swapped.
Why do brands and payment companies choose Polygon over other blockchains? Polygon offers a combination of low fees, Ethereum compatibility, years of proven infrastructure, and an active partnerships strategy that has attracted both consumer brands and, more recently, payments infrastructure players. Brands generally want a chain cheap enough for mass consumer use but still connected to Ethereum’s broader ecosystem and credibility, while payment companies like Visa have valued Polygon’s throughput and cost profile for stablecoin settlement specifically.
Is Polygon still relevant in 2026? Yes, though its story has shifted from a single flagship ZK rollup to a broader ecosystem strategy. Polygon PoS continues setting new transaction records, AggLayer has gone live connecting well over 100 CDK built appchains, and the network landed a notable real world validation with Visa’s 2026 stablecoin settlement partnership, even as the POL token itself has traded well below its earlier highs alongside a broader crypto market downturn in 2026.
