NewsCrypto Plans to Integrate Chainlink Proof of Reserve for Their Polygon Token Bridge

NewsCrypto is announcing their plan to integrate Chainlink — the world’s leading decentralized oracle network — into the token bridge that they announced this month. When it comes to blockchain interoperability and bringing cross-chain liquidity to DeFi, security is absolutely crucial, and there’s no better way to ensure it than by implementing the best and most trustworthy data sources out there.

Recently, the NewsCrypto team announced that they’re working on a token bridge for Polygon, the largest full-stack Ethereum scaling solution in the crypto space. The bridge will enable billions of dollars worth of liquidity on one of the oldest and most popular chains in crypto (the name of which will be revealed when the testnet implementation is live) to access everything that the Polygon ecosystem has to offer. That way, token holders will be able to securely transfer their funds over to Polygon, where they can put them to work in the ever expanding DeFi ecosystem by trading or providing liquidity on DEXes, lending, borrowing and more.

The team is aware that, when it comes to cross-chain bridges, security is the number one concern, and that’s why they’re working on implementing multiple layers of redundancy to make the protocol as safe as possible. A vital part of this is obtaining reliable data from a trustworthy source about the balances and transactions on the wallets which are used for the swap, and that’s where Chainlink Proof of Reserve comes in. By running an independent node, Chainlink will enable the smart contract that will be used for the swap to continuously keep track of relevant token balances and prevent illegitimate transactions.

This, however, is not all when it comes to the integration. The token bridge is only the first stage, and further down the line, NewsCrypto will also deploy a lending and borrowing protocol on Polygon, which will feature innovative ways of incentivizing both liquidity suppliers and borrowers. For this purpose, the team will use Chainlink Price Feeds, which are without a doubt the most established and trustworthy DeFi data source in the industry. And, for generating provably random and fair extra rewards, the team also intends to implement Chainlink VRF. More details on the various stages will be announced in the near future, so be sure to keep an eye out on the official NewsCrypto Twitter page.
