 The default provider for above mainnet chains is `0x52DeaA1c84233F7bb8C8A45baeDE41091c616506`. The Fortuna URL for the default provider is `https://fortuna.dourolabs.app/v1/chains/<chain>`,
 where `<chain>` is the chain id from the leftmost column.
 
+The default provider on mainnet has a reveal delay to avoid changes on the outcome of the Entropy request because of block reorgs.
+The reveal delay can be a number of blocks (measured from the `latest` block) or `safe` which means the reveal will be delayed until the request transaction is included in a block with `safe` tag.
