Bittensor EVM Smart Contracts
How Bittensor supports Ethereum Virtual Machine-compatible smart contracts on Subtensor.
-
Block
How a block groups Bittensor transactions into an ordered blockchain record.
-
Chain Reads
How chain reads describe looking at public Bittensor chain state without asking Subtensor to record a new action.
-
Existential Deposit
How existential deposit names the minimum TAO balance threshold for retaining a Bittensor account.
-
Extrinsics
Extrinsics are Bittensor chain actions that ask the Subtensor runtime to process a state-changing operation.
-
Mempool
How the Bittensor mempool holds pending transactions before block inclusion.
-
Rate Limits
How Bittensor rate limits use block-based cooldowns to pace repeated chain actions.
-
Subnet Stake Burn
How subnet stake burn adds TAO to a subnet reserve while permanently removing alpha from circulation.
-
Subtensor Constants
How Subtensor runtime constants expose named reference values grouped by runtime area.
-
Subtensor Error Codes
How Subtensor error-code families help Bittensor readers interpret failed chain actions.
-
Subtensor Events
How Subtensor runtime events provide named records of Bittensor chain activity.
-
Subtensor Storage
How Subtensor runtime storage entries organize Bittensor chain state by runtime area.
-
Token Bridging
How token bridging connects TAO between Substrate (SS58) and EVM (H160) account contexts on the Bittensor chain, and how vTAO represents staked TAO inside the EVM layer.
-
Transaction Fees
How Bittensor distinguishes base chain transaction fees from swap fees tied to stake-related actions.
