Polygon Expands CDK Privacy Stack for Banks, Stablecoins, and Tokenized Funds

• Polygon has expanded CDK Privacy Stacks to allow institutions to keep private transactions on the public blockchain.

• The solution offers privacy and compliance without compromising on decentralization.

Polygon has unveiled a new upgrade that could encourage financial institutions to build on the blockchain. In an X post, the team unveiled a new privacy upgrade on their Polygon CDK framework, an open-source framework designed to launch custom, ZK-powered L2 blockchains on Ethereum.

Blockchain is decentralized by design, which means transactions are visible and verifiable by everyone. But the world is increasingly calling for more privacy, and Polygon is now giving a private solution to financial institutions. The upgrade will allow institutions to build private blockchains with transactions hidden, but with public confirmation on Ethereum, powered by Succinct.

The team explains that raw transaction data remains in the institution-operated data availability environment, never in the public network. Ethereum can confirm everything is running correctly after receiving a cryptographic commitment and a zero-knowledge proof.

Polygon Builds Institutional Privacy

It further notes that this privacy will be available on 5 levels. At one of the levels, which is the Confidential user transactions, all transactions will be kept on the private infrastructure. This means the sender, receiver, and transaction amount are all hidden, and only approved auditors can check records when needed.

Another level is confidential tokens, where balances and transfer amounts stay hidden so that nobody can publicly see who holds what or how much is being moved. With Confidential Compute, all transactions are within a secure environment where not even the blockchain operator can see what’s happening. Permissioned access will only allow approved people to view, with data only visible to those with access. With Confidential Chain, details stay completely inside the institution’s private systems, with proof that everything is valid sent to Ethereum.

Polygon adds that the private systems will still enjoy the liquidity benefits offered by the ecosystem, because all CDK chains are connected to Agglayer, its cross-chain settlement layer.

The post notes:

“A private CDK chain is built for institutions that are already past the question of whether to come onchain and are now asking how to do it without compromising on privacy, compliance, or ownership.”

The team invited various kinds of institutions, singling out banks launching tokenized deposit products, payments companies with stablecoin corridors, asset managers issuing tokenized funds, regional banks offering stablecoin rails to corporate clients, and crypto-native teams that need high throughput with enterprise SLAs.

Polygon has been on an impressive run in institutional adoption. As ETHNews reported, earlier this month, Visa announced that it is adding Polygon to its global stablecoin settlement program. Meta, formerly Facebook, also launched its USDC creator payout program on the Polygon network.

At the time of writing, Polygon’s POL coin is trading at $0.1006 after a** 1% **drop in the last 24 hours. Like most altcoins, the coin is facing massive selling pressure at key breakout positions, preventing it from retesting higher resistance levels.
