Cómo obtener el último número de bloque en segundos (TEST_URL = prueba RPC BSC):
const provider = new ethers.providers.JsonRpcProvider(Process.env.TEST_URL); let timestamp = 0; // Block Number provider.getBlockNumber().then(function(blockNumber) { timestamp = blockNumber; });Creo que esto es lo que estás buscando
// Get the block number provider.getBlockNumber().then(function(blockNumber) { // getBlock returns a block object and it has a timestamp property. provider.getBlock(blockNumber).then(function(block) { // Assign block.timestamp to timestamp variable timestamp = block.timestamp; } });
