Bittensor debugger
Paste a hotkey, a transaction or a netuid. Preflight reads the chain at one block, names the cause, hands you the command that fixes it, and lets you test the next transaction before you spend a single rao
Routes to the Doctor, the tx debugger, the error explainer or a subnet
UID 0 on SN64 earns nothing because no validator has scored it
No validator has scored this UID
Next step Check that the axon is reachable and that the miner answers the subnet's queries in the format validators expect
Four modules, one engine
Each card below is a recorded read from block 9,376,730. The same engine answers the CLI, the HTTP API and the MCP server
Why does my miner earn zero?
This hotkey on SN64 is not registered
Why did this extrinsic fail, and what do I run instead?
SubtensorModule.remove_stake
InsufficientLiquidity
The unstake amount was too small to swap
$ btcli stake remove --netuid 64 --hotkey 5DU1dvXbvjVRs5omKrbZzLNB6ZL9uNnzQrS1H8MFcSdFS7ww --amount 1 --network finney
Will this work, before I pay for it?
burned_register on SN64, coldkey with 0 TAO
Would fail: The coldkey cannot pay the fee
What does each subnet do, and what does launching one cost?
Subnet lock cost now

They show, Preflight explains
Taostats, tao.app, bittensor.ai and Metagraphed are good at showing chain data. None of them explains a zero incentive, turns an error into a command, or lets you try an extrinsic before you pay for it
