The Polygon Network brings massive scale to Ethereum using an adapted version of Plasma with PoS based side chains that provides a solution for faster and extremely low-cost transactions with finality on the main chain. The Polygon network ensures liveliness using PoS checkpoints which are pushed to the Ethereum mainchain. This enables a single Polygon sidechain to theoretically achieve
2^16 transactions per block, and possibly millions of transactions on multiple chains in the future.

Quickstart overview video
address, return current token balances along with their spot prices. This endpoint supports a variety of token standards like ERC20, ERC721 and ERC1155. As a special case, network native tokens like ETH on Ethereum are also returned even though it’s not a token contract.
address, return all transactions along with their decoded log events. This endpoint does a deep-crawl of the blockchain to retrieve all kinds of transactions that references the
addressincluding indexed topics within the event logs.
Matic Gas token
MATIC token is the native token of the Matic network. This is similar to Ether in Ethereum. To interact with the Matic network, MATIC tokens are required to pay as gas fees. Covalent’s responses automatically returns
gas_* fields in the MATIC units.
Covalent maintains an on-chain real-time mapping of token addresses between Ethereum mainnet and the Matic chain. These addresses are used to reverse-lookup prices on Matic and also to return the right token logo urls.
Some example of mapped tokens:
|Token||Ethereum mainnet||Matic mainnet|
For tokens that have a mapping back to Ethereum mainnet, Covalent is able to return the mapped prices.
The following provide infrastructure for this blockchain network:
