HODL is Bittensor subnet 118 (SN118), a project in the DeFi and Portfolio Management lane. The ETF subnet for Bittensor alpha
HODL rewards miners for holding conviction, not running models. It's Bittensor's portfolio indexing and market-making subnet, turning long-term staking into scoreable, on-chain proof of conviction.

What is HODL (SN118)?
HODL is a Bittensor subnet built around financial participation rather than AI compute. Miners earn emissions by staking into structured portfolio indexes or providing liquidity as market makers on the HODL Exchange. It's financial infrastructure running on Bittensor's incentive layer.
In plain English: It's like a crypto ETF protocol where the "fund managers" are replaced by an on-chain scoring system that rewards long-term conviction and active market making.

How miners and validators work
Like every Bittensor subnet, SN118 is a two-sided market: miners produce work, validators score it, and emissions follow those weights under the network’s dTAO economics.
- Miners either stake their coldkey in TrustedStake portfolio indexes (ETF track) or fill buy/sell orders on the HODL Exchange (market-making track)
- Validators evaluate miner scores using a time-weighted staking formula and fill-volume metrics, then set weights that determine emission distribution
Mechanism and design
The subnet divides emissions between two parallel miner programs, currently at a 75/25 split.
The ETF track rewards miners who stake their coldkey in one of five TrustedStake portfolio indexes: TSBCSI, Top 10, Full Stack, Fintech, and Bittensor Universe. Miner score follows a time-weighted formula: score equals stake amount multiplied by a duration multiplier of (1 + 0.25 times the natural log of (1 + days held divided by 30)). The longer a position is held, the higher the score multiplier. The design is non-custodial: TrustedStake can stake and unstake on behalf of the miner but cannot transfer funds. Notably, TrustedStake explicitly excludes subnet 118 from its own indexes to avoid conflicts of interest.
The IMM track (Incentivized Market Making) rewards miners who fill orders on the HODL Exchange. Score is based on total fill volume over a rolling five-day window. For buy orders, purchased assets must remain in the miner's coldkey during the window, creating a light proof-of-inventory requirement that discourages wash trading.
The roadmap adds derivative products over time: V3, targeted for Q3 2026, introduces futures and options, with transaction fees from V2 and V3 committed to automatic alpha buybacks.
The 7-day net inflow sits at roughly 349 TAO, with a 7-day price gain near 18.8%. Emission share is approximately 0.41%, against an EMA of 0.64%, suggesting the subnet is still building toward its long-run flow baseline. Root proportion is at 33%, indicating a mix of organic staking demand and protocol subsidy in the pool.
Why the project exists
- The problem it solves: Getting diversified exposure to Bittensor's subnet ecosystem is complex. There's no native ETF primitive, no structured portfolio product, and no on-chain incentive for long-term conviction. HODL builds that layer directly.
- The opportunity: As Bittensor scales to more subnets, capital allocation infrastructure becomes foundational. A protocol that rewards informed, long-term positioning creates a counterweight to short-term speculation.
- The Bittensor advantage: The scoring formula is transparent and on-chain. No single manager decides what a good portfolio looks like: the incentive mechanism does.
- Traction signals: GitHub shows 54 commits from 4 contributors with activity through April 20, 2026. TrustedStake integration is live with five supported indexes. The HODL Exchange, originally targeted for Q1 2026, is referenced in active present-tense documentation.
What stakers should check before buying alpha
Subnet storytelling is cheap. On-chain and product checks are not. Use the same framework as our subnet metrics guide:
| Check | Why |
|---|---|
| Real product / docs / repo | Separates shipping teams from narrative-only slots |
| Pool depth (TAO) | Your exit door: thin pools amplify slippage |
| Net flows (7d / 30d) | Under flow-based emissions, capital votes with its feet |
| Emission share | Whether the market is funding this subnet right now |
| Ownership concentration | Large holders can move a small alpha market |
| Immunity / deregistration | Post-immunity weak slots can lose the race (see immunity guide) |

Risk factors
- TrustedStake dependency: The ETF track is built entirely on TrustedStake's indexing infrastructure. Any degradation in TrustedStake's service, trust model, or availability would directly affect miner scoring and ETF participation.
- Thin liquidity pool: With approximately 2,800 TAO in the liquidity pool relative to a market cap of roughly 7,700 TAO, larger positions carry meaningful slippage risk.
- Exchange liquidity bootstrap: The IMM track depends on the HODL Exchange attracting genuine order flow. Without sufficient volume, market makers have limited incentive to participate, and the 25% emission allocation to IMM goes underutilized.
- Small active miner base: A small number of active miners means emission distribution is currently concentrated. The scoring mechanism becomes more robust as more participants join.
How this fits a TAO portfolio
Many holders keep a root vs subnet split: root for calmer TAO exposure, subnets like HODL for thematic upside (and higher variance). If you use TaoScale, you can size SN118 from your wallet without handing over custody. See non-custodial staking.

FAQ
What does HODL do on Bittensor?
It's like a crypto ETF protocol where the "fund managers" are replaced by an on-chain scoring system that rewards long-term conviction and active market making.
What is the SN118 alpha token?
When you stake TAO into subnet 118, you receive that subnet’s alpha. Its price versus TAO moves with the subnet’s pool (see what is dTAO).
How do I research HODL before staking?
Read the mechanism above, open the official repo/docs when available, then verify pool depth, flows, and activity on SN118. Cross-check with the metrics checklist.
Is this financial advice?
No. TaoScale publishes educational explainers and live tools. Decisions to stake are yours alone.
Not financial advice. Educational overview of HODL (SN118) compiled from public project materials and ecosystem documentation. Mechanisms and market structure change, so verify live data and official sources before acting.
