DarkPool. Prediction Markets on DeepBook V3

`create-v3-pools`

Creates Pool<YES, DUSDC> + Pool<NO, DUSDC> on DeepBook V3 via create_permissionless_pool (500 DEEP fee each). Writes pool ids back into registry.json. Skips legs whose pool already exists.

pnpm tsx scripts/create-v3-pools.ts --slug btc_80k_eoy --execute

Flags

Flag	Required	Description
`--slug`	yes	Market slug from registry
`--tick-size`	no	V3 tick size (default: 1_000)
`--lot-size`	no	V3 lot size (default: 100_000)
`--execute`	no	Sign + submit

The script auto-buys DEEP with SUI when the book can fill, else exits with the exact ask.

Testnet DEEP had been blocked until 2026-06-11. The DeepBook team granted 1000 DEEP + 200 DUSDC and pool creation worked exactly as designed. The full 1000 DEEP was consumed as the 2×500 creation fees (tx 3Bq5VDoacnmgdHU6WfHaMVxkwC7LD5U86MUYFxetYm6W).

`seed-v3-liquidity`

Bootstraps a two-sided book on both pools in one PTB:

Mint YES + NO pairs from wallet DUSDC (5% fee headroom).
Deposit tokens + bid funds into a BalanceManager (created + shared in-PTB, or reused via --bm).
POST_ONLY bid/ask per pool with pay_with_deep=false (input-token fees).

pnpm tsx scripts/seed-v3-liquidity.ts \
  --slug btc_80k_eoy \
  --qty 50 \
  --bid 0.45 \
  --ask 0.55 \
  --execute

Flags

Flag	Required	Description
`--slug`	yes	Market slug from registry
`--qty`	no	Per-side quantity (default: 50)
`--bid`	no	Bid price (default: 0.45)
`--ask`	no	Ask price (default: 0.55)
`--bm`	no	Reuse an existing seeder BalanceManager id
`--execute`	no	Sign + submit

Exits 3 with DEEP guidance until create-v3-pools has run. The seeder BalanceManager id (printed at first run) gets reused via --bm to top up or re-quote without re-creating.
