The main issue with monolithic blockchain systems is the requirement to unify execution, settlement and data availability in a single block. The modular blockchain trend was initiated by Layer 2 (L2) rollups, which enabled execution to be handled on a separate chain with blocks devoted only to execution. By separating data availability as well as enabling a chain with blocks specifically for data availability, Polygon Avail advances modular architecture.
NFT marketplace OpenSea now supports MATIC as payment option
In June, NFT marketplace OpenSea introduced Seaport, an open-source Web3 marketplace protocol for buying and selling NFTs. Seaport, which was first introduced on Ethereum, has contributed to making Web3 marketplaces like OpenSea more affordable.

OpenSea reports that it has now added Polygon support to Seaport after studying the effects of Seaport for several months and gathering insightful comments. It promises to extend support for Klaytn and other EVM-compatible chains in the upcoming months.

Previously, the 0x protocol was used to power Polygon on OpenSea. Polygon is now moving to Seaport. OpenSea claims that the action will enable the release of new features to all EVM-compatible chains more quickly.
Due to this shift, OpenSea now supports the use of MATIC, Polygon’s native token, as a payment option. Users transacting on Polygon will now be required to pay gas fees to transact on OpenSea using MATIC.
MATIC is also available for purchase using MoonPay or on any exchange where MATIC is offered.
