How SWELL Works

Two ecosystems

What each side brings

Bittensor has a fast-growing market of AI subnets, but reaching it takes a TAO wallet, Bittensor tooling and subnet research. Robinhood Chain has users and dollar liquidity looking for assets with real activity behind them. SWELL connects the two.

Robinhood Chain brings

Users and liquidity. Traders who already hold dollars on chain and know how to use a pool.
A simple market. SWELL trades against USDG like any other token on the chain.
Demand from outside crypto-native AI circles. People who want AI-sector exposure without a new wallet or a new chain.

Bittensor brings

Productive assets. Subnet alpha tied to networks doing real AI work, with staking rewards.
Transparent state. Pool prices, stake and validator data are all on chain.
Breadth. More than a hundred subnets, from compute to inference to training.

Who benefits

Four sides, one token

TAO holders

Subnet exposure in one mint

Deposit TAO once for exposure across many subnets instead of buying and tracking each one.
Staking rewards stay in Harbor and raise backing per SWELL.
No ongoing fees. Only mint and redeem fees.
Redeem back to TAO through Portal.

Robinhood Chain users

The flywheel

How demand turns into Bittensor capital

Trading SWELL on Robinhood Chain does not add TAO to Bittensor by itself. Primary minting does. The loop links the two through a simple price incentive.

1
DemandPeople on Robinhood Chain buy SWELL in the SWELL / USDG pool.
2
PremiumWhen the pool price rises above the cost of a primary mint, minting becomes the cheaper way to get SWELL.
3
MintArbitrageurs deposit TAO through Portal, mint new SWELL and sell into the pool. That pulls the price back toward backing.
4
HarborThe deposited TAO lands in Harbor as new backing.
5
DeployCurrent stakes it across the subnet basket, delegated to validators.
6
BackingStaking rewards stay in Harbor. A bigger, visible basket draws more demand, and the loop repeats.

Runs alongside: transfer burn

Every normal SWELL transfer pays a 0.50% fee that is burned in full. Supply shrinks while Harbor stays the same, so backing per SWELL rises for everyone still holding.

Arbitrage

What keeps the price near NAV

SWELL trades freely in the pool, so its price can drift away from NAV per SWELL. When the gap gets bigger than the cost of closing it, anyone can profit by minting or redeeming through Portal. Both trades push the price back toward NAV. Neither one lowers NAV per SWELL for people who are just holding.

Premium

Pool price above NAV

Deposit TAO in Portal
Mint new SWELL at backing
Sell SWELL in the pool

Pool price: Falls toward NAV as new SWELL is sold.
NAV per SWELL: Unchanged by the mint. The minter pays the mint fee and the cost of deploying their TAO. The 0.50% burn on the pool sale nudges it up.
Harbor: Grows. New TAO is staked into subnets.
Supply: Grows by the SWELL minted.

Discount

Pool price below NAV

Buy SWELL in the pool
Burn it through Portal
Receive TAO at NAV

Pool price: Rises toward NAV as SWELL is bought.
NAV per SWELL: Unchanged by the redemption. The redeemer pays the redemption fee and the cost of selling their share of alpha. The 0.50% burn on the pool buy nudges it up.
Harbor: Shrinks. Alpha is sold to pay out TAO.
Supply: Shrinks by the SWELL burned.

Why there is a band, not a peg

Each trade has costs: the 0.50% mint fee or 0.75% redemption fee, the 0.50% transfer burn on the pool side, pool fees, slippage when Current deploys or sells alpha, and settlement time. Small gaps are not worth closing, so the price can sit a little above or below NAV. Larger gaps attract arbitrage until they shrink back inside the band.

Across two chains

What happens on each chain

A mint starts on Bittensor and finishes on Robinhood Chain. A redemption runs the other way. Wake links both halves of every request under one ID.

Where value goes

Value ledger

Who	What they get	Where it comes from
SWELL holders	Higher backing per SWELL	Staking rewards kept in Harbor, transfer burns, and basket performance, which can be negative.
Bittensor	New TAO staked into subnets	Primary mints only. Secondary trading moves existing SWELL between holders.
Robinhood Chain	A new asset and trading volume	SWELL / USDG trading and arbitrage around backing.
Operator	0.50% of mints, 0.75% of redemptions	Processing fees only. Nothing from staking rewards or transfer fees, and no ongoing fees.

Worked example

What one transfer burn does

Harbor holds 100 TAO backing 1,000,000 SWELL. Someone transfers 100,000 SWELL.

Before0.00010000TAO backing per SWELL

Burned500 SWELL0.50% of the transfer. Supply falls to 999,500.

After0.00010005TAO backing per SWELL. Harbor is unchanged.

Shared vocabulary

Terms from both sides

New to Bittensor

TAO: The native token of Bittensor. SWELL is minted and redeemed in TAO.
Subnet: A network inside Bittensor focused on one kind of AI work.
Alpha: A subnet's own token, bought by staking TAO into that subnet's pool.
Validator: The operator that stake is delegated to. Validators earn rewards and share them with stakers.
Root: Staking TAO itself rather than a subnet's alpha. Harbor keeps a reserve here to pay redemptions.

New to Robinhood Chain

Robinhood Chain: The network where SWELL lives and trades.
USDG: The dollar stablecoin SWELL trades against at launch.
Pool: The SWELL / USDG market. Its price can sit above or below backing.
Transfer burn: The 0.50% fee on normal transfers, destroyed rather than paid to anyone.
Backing per SWELL: Everything Harbor holds, valued in TAO, divided by SWELL supply.

Limits

What the flywheel does not do

It has no peg. SWELL can trade above or below backing. Fees, settlement time and liquidity create a band, not a fixed price.
A premium compresses. Each mint adds supply, so the gap that drives minting tends to close.
It can run in reverse. Below backing, holders redeem, and Current sells alpha to pay them in TAO.
Subnet prices move. Backing falls when the basket falls. Staking rewards do not cover every drawdown.
Only mints add TAO. Trading volume alone does not grow Harbor.
No guarantees. There is no principal guarantee, founder backstop or make-whole obligation.
