debug_traceBlockByNumber

It accepts a block number and will replay the block that is already present in the database.

Parameters:

QUANTITY|TAG - integer block number, or the string "latest", "pending"

Due to the high block speed of Optimism, this method with "latest" parameter will probably get error code 32000 with message “block #-1 not found”

Object - tracer

• tracer: string - the type of tracer. Currently supports callTracer and prestateTracer

Returns:

Array - Block traces

Example:

// Request
curl https://optimism.blockpi.network/v1/rpc/your-rpc-key -X POST -H "Content-Type: application/json" --data '{"method":"debug_traceBlockByNumber","params":["latest", {"tracer": "callTracer"}],"id":1,"jsonrpc":"2.0"}'

// Result
{
    "jsonrpc": "2.0",
    "id": 1,
    "result": {as described above}
}
