Latest Block Number on an EVM Chain

evmrpc/block-number

The newest block number of an EVM chain right now, as a decimal number and as the node's hex. Read from public nodes that offer no SLA and can be slow, throttled or a block behind; a failing node is replaced by another operator's automatically. Served by Eden Engine; not an official product of any chain or node operator.
