Shadow

Late in the round, match a percentage of each occupied tile’s current SOL. You pick how many solo and split tiles. Skips a quiet board. Volume-share, not EV. Type 2 mode 9.

What it does

Shadow waits until late, looks at tiles that already have SOL, and deploys a percentage of each occupied tile’s current stake — walking the board until your bankroll cap is spent. Empty tiles are skipped. This is volume-share mirroring, not an EV ranker.

In plain english

Follow occupied tiles at a fraction of their size. Quiet boards → sit out. Busy boards → shadow the crowd up to your cap.

Not the retired Percentage strategy

Older docs described Shadow as retired on-chain type 1 / type 4. The live picker Shadow is Type 2 manual mode 9. Ignore any “Shadow is retired” banner on old copies of this page.

Settings

Bankroll cap

Maximum SOL this miner spends matching occupied tiles in a round. Clamped to your on-chain balance.

Solo tiles / Split tiles

How many of the most-crowded solo (0–10) and split (0–15) tiles to take. Default 10 / 15 (all).

Match occupancy

Deploy this share of each occupied tile’s current SOL. Example: 5% means roughly amount = P × T / (10000 − P) on each occupied tile until the bankroll cap is hit.

Occupied tile stake: 1.0000 SOL
Match occupancy: 5%
Shadow adds about: ~0.0526 SOL
Empty tiles: skipped

Starting recommendation

Start with match occupancy around 5%, defaults 10 / 15, and a bankroll cap you are willing to spend on a busy board.

Gates

Optional skip gates in the strategy picker (off by default). They do not change tiles or amounts — only whether this round fires.

Crowded-round skip gate — sit out when recent network-wide SOL is above your cap. See Crowded-round skip gate.
Motherlode range gate — sit out when the live motherlode pool is below your min or above your max ORE. Leave a side empty to ignore that bound. See Motherlode range gate.

How to set up

Connect your Solana wallet on the Mining page.
Create a miner and choose Shadow in the strategy picker. Set bankroll cap, solo/split counts, and match-occupancy %.
Sign the transaction. This creates your miner accounts on-chain (Manager + Strategy Deployer + ORE Miner). Cost ≈ 0.005 SOL (account setup).
Deposit SOL. Transfer SOL into your miner’s autodeploy balance. Minimum 0.03 SOL; 0.3 SOL or more gives runway for many rounds.
Done. The crank runs this strategy each round. Activity shows deploys and skip reasons.

When it skips a round

Quiet board — not enough occupied tiles to shadow
Bankroll cap too small after fees / minimums
Paused, insufficient balance, or optional crowded-round / motherlode-range skip

Things to know

Volume-share, not EV. Crowded tiles get followed whether or not they look +EV.
Late fire. Shadow shares the late window so it can see occupied stakes.
One-sided boards concentrate your spend where the crowd already is.

Worked example

Late occupancy match: take a % of each occupied tile’s SOL until the bankroll cap is spent.

Activity (C) and Results (D) match what you see in the Mining Activity / Sessions panels. Thinking (B) illustrates what the crank evaluates that round — only EV Gate has a live Strategy Insight table in-app.

Skip variant (same config)

When the late board has no occupied tiles to mirror, Shadow sits out — empty tiles alone never trigger a deploy.
