}Robinhood Chain API method that returns a human-readable representation of a block. Unlike
eth_getBlockByNumber which returns structured JSON, this method returns a verbose text dump of the entire block structure including all header fields, transactions, and uncles. The output format uses Go’s spew.Sdump formatting.
Learn how to deploy a node with the debug and trace API methods enabled.
This method is available for post-Nitro blocks only (block 22,207,815 and later). For pre-Nitro blocks, use the
arbtrace_* methods instead.Get your own node endpoint todayStart for free and get your app to production levels immediately. No credit card required.You can sign up with your GitHub, X, Google, or Microsoft account.
Parameters
number— the block number as a decimal integer.
Response
result— a human-readable string representation of the block, including all internal fields and nested structures.
