Bittensor has two layers of tokens. TAO is the root currency of the whole network. dTAO tokens are subnet-specific assets that let markets signal which subnets are actually delivering value.
TAO is the native currency of Bittensor. It is minted on a fixed schedule as block rewards and distributed to miners and validators based on their performance within each subnet. Holding TAO gives you a claim on the overall economic output of the network.
TAO is also the staking token. To participate as a validator or to delegate stake to one, you lock TAO. This creates a direct link between economic skin-in-the-game and voting power over which miners receive emissions — the more TAO staked with a validator, the more influence that validator’s weights carry.
With the dTAO upgrade, every subnet has its own token — its “alpha” token — that trades against TAO in an automated market maker (AMM) pool. Staking TAO into a subnet means buying that subnet’s alpha token, which represents your proportional stake in that subnet’s validator set.
The price of each subnet’s alpha token reflects the market’s collective judgment of that subnet’s value. A subnet producing high-quality AI work attracts stakers, which drives its token price up, which in turn increases its share of the global TAO emission. This market signal replaces the older system of fixed emission allocations voted on by root network validators.

Insight: Staking is a value signal
When you stake TAO into a subnet, you’re not just earning rewards — you’re voting with capital. The collective stake across all subnets determines how the network allocates its total emissions. High-stake subnets attract more miners, which can improve AI output quality, which should attract more stake. The system is designed so that capital and quality reinforce each other.
Each block mints new TAO. That block reward is split across subnets in proportion to what is staked in each alpha pool, and then split again inside the subnet between the miners who did the work and the validators who scored it. Two competitions, both settled by market and consensus rather than by a committee — which is why an alpha price is a claim on a share of an emission stream, not just a ticker.
dTAO tokens (also called alpha tokens) represent your stake in a specific Bittensor subnet. Each subnet has its own dTAO token with a price set by an on-chain automated market maker (AMM). When you stake TAO into a subnet, you receive dTAO tokens in return, giving you exposure to that subnet’s emissions and performance.
How does trading dTAO work?
Trading happens through an on-chain AMM. You swap TAO for dTAO to stake into a subnet, or swap dTAO back to TAO to unstake. Prices adjust algorithmically from the TAO/dTAO reserve ratio — there are no order books, no counterparties, and no centralized custody.
What is the difference between staking and trading dTAO?
They are the same on-chain action. Buying dTAO for a subnet stakes TAO into that subnet’s pool; selling dTAO unstakes it. The “trading” framing emphasizes price discovery and short-term position management; “staking” emphasizes long-term exposure to a subnet’s emissions and validator rewards.
How is dTAO price determined?
Each subnet has a TAO and dTAO reserve held by the Subtensor pallet on-chain. Price is the ratio of those two reserves, adjusted by the constant-product AMM curve on every swap. Larger trades move price more — slippage is a function of trade size relative to TAO reserve depth.
Are there fees for trading dTAO on Bittensor?
dTAO swaps execute through the on-chain AMM, so you pay only the standard network transaction fee in TAO. There are no platform trading fees, spreads, or maker/taker charges levied by Bittensor.ai.
What is the minimum amount of TAO needed to trade dTAO?
There is no protocol-enforced minimum, but every swap pays a small TAO transaction fee, and very small trades can move price by less than one rao. Practically, sizing a trade in line with the subnet’s pool depth (visible in the trade workspace) gives the best execution.
How do I buy a specific subnet token (e.g. SN8 or SN21)?
Open the trade workspace, search the watchlist or use ⌘K to find the subnet by netuid, name, or symbol, then enter a TAO amount in the trade panel. The AMM quote previews the dTAO you will receive before you sign the on-chain transaction with your wallet.
Can I withdraw dTAO back to TAO?
Yes — selling dTAO unstakes the underlying TAO from the subnet pool back to your wallet at the current AMM price. There is no lockup. Settlement is immediate on the next block.
Is trading dTAO safe?
dTAO swaps run on the Bittensor (Subtensor) chain itself — there is no third-party exchange, custodian, or bridge. The risks are smart-contract / runtime risk on the Bittensor protocol and market risk on the subnet you are buying. Self-custody of your wallet keys is required.
How is this different from buying TAO on a centralized exchange?
A CEX gives you exposure only to TAO, the network’s base asset. dTAO trading lets you allocate TAO across specific Bittensor subnets — concentrating exposure on the AI workloads (LLMs, image generation, agents, finance) you believe in, with rewards flowing from those subnets’ emissions rather than just TAO price.
