Polygon CDK enables institutional migration to Ethereum-aligned ecosystems

The Polygon Chain Development Kit (CDK) provides a necessary path for institutions to move from isolated private chains to an Ethereum-aligned ecosystem. The Polygon CDK includes Hyperledger Besu support to connect institutional chains to the AggLayer. This configuration allows banks to run private networks using QBFT consensus. Institutions maintain transaction data within their own infrastructure. The integration of the Hyperledger Besu client into the Chain Development Kit ecosystem aims to address the structural technical limitation of private networks through a native connection to the AggLayer network infrastructure. The configuration embeds bridge contracts directly into the network’s genesis block. This allows cross-chain interoperability from the first block. The setup uses zero-knowledge proofs and Succinct prover network technology to provide mathematical validity proofs. These "pessimistic proofs" restrict withdrawal operations so that no connected chain withdraws more funds than it originally deposited into the shared bridge. This mechanism removes the need for centralized trust in human validation committees. Institutions adopt five configurable privacy layers as requirements evolve. Permissioned Access provides role-based RPC endpoints and enterprise SSO integration like Okta or Azure AD. Confidential Chain keeps transaction data private within institutional infrastructure. Confidential Compute provides an execution environment for workloads like dark-pool matching and encrypted RFQs. Confidential Tokens uses completely homomorphic encryption on permissioned token rails. Confidential User Transactions uses client-side zero-knowledge proofs for shielded pools at the wallet level.

AggLayer interoperability and throughput

The AggLayer provides a unified interoperability protocol to reduce blockchain fragmentation and enable users to pay from any chain to any chain. This protocol addresses the issue where users, merchants, and wallets sit on different chains and must bridge manually. Polygon increased its block gas limit from 120 million to 140 million gas to support high-volume decentralized applications and payments. This upgrade raises the theoretical maximum throughput to more than 3,800 transactions per second. You should know that this increased capacity aims to enable more on-chain payments at scale. AggLayer functions via open-source components like aggkit. The network uses a permissioned sequencer that the developer controls. CDK Enterprise provides 200 MGas/sec throughput and 30,000 RPS capacity with 99.99% uptime. The CDK also processes over 1.2 billion transactions across 20+ production chains.

The Open Money Stack and stablecoin payments

Polygon builds the "Open Money Stack" to manage on-ramps, wallets, settlement, and regulated fiat access. The network supports over $3.4 billion in on-chain stablecoin supply with average fees near $0.002 and finality under five seconds. In 2025, Revolut moved $810 million on the network. Tazapay processed $687 million in January 2026 alone, while Stripe processed more than $75 million in payments. The network captured 61% of monthly DEX volume for non-USD stablecoins across APAC, LATAM, and Africa in December 2025. The system uses native USDC; Circle says this asset is redeemable 1:1 for U.S. dollars. The network also uses ERC-4337 account abstraction; this enables apps to sponsor fees through paymasters and relayers. More than $14 billion in stablecoin payment volume has settled across 41 entities. DeCard says it can enable stablecoin payments at 150 million plus merchants using Polygon for settlement. The network supports more than 30 non-USD stablecoins across APAC, LATAM, and EMEA regions. However, stablecoin payments still depend on compliant local partners for on-ramps, off-ramps, KYC, KYB, and local currency delivery. Can the network overcome these edge-case dependencies?
