opBNB
Infura provides open beta access to the layer 2 opBNB and its layer 1 BNB Smart Chain (BSC). During this period, there might be feature limitations. Performance issues are not expected, but they are possible as we optimize and stabilize the service.
Archive requests are not currently supported for opBNB: only near head requests (the last 128 blocks) are supported. Be aware of this limitation when making calls
to API calls to methods such as eth_getStorageAt,
eth_getTransactionReceipt, and
eth_getTransactionByHash.
opBNB is an EVM-compatible, layer 2, rollup scaling solution that operates on top of BSC. All transactions that occur on opBNB are posted and validated on BSC using Optimistic Rollups.
For more information, refer to the official opBNB documentation.
