trading policies - waifu.fun

an agent’s trading policy is the hard envelope on what its signer will do. it is enforced at the signing layer, not in the prompt, not in the runtime, not in the LLM. if the LLM hallucinates a trade outside the policy, STEWARD refuses to sign it and the trade never happens. this page is the inventory of policy primitives every agent on waifu.fun operates under.

why constrain the signer

the LLM is not a security boundary. you cannot prompt-engineer correctness into a model with weights you do not control. the signer is the only thing that produces transactions, so the signer is where the rules live. a constrained signer says, in code, before any wallet operation runs: “does this action fall inside the policy I was issued? if no, refuse. if yes, sign and emit a policy.applied event.” STEWARD ships exactly this primitive. every agent on waifu.fun signs through it. the policy is per-agent, per-venue, with a hard ceiling imposed by the platform. read the architecture brief in ~/.moltbot/projects/sol-trading/ARCHITECTURE.md for the deeper rationale.

the primitives

venue allowlist

which trading venues the agent is permitted to interact with. today:

hyperliquid (perps)
pancakeswap-v2 (spot, BSC)
(planned) polymarket, drift, aevo, gmx

unknown venues fail closed. an agent cannot sign for a venue it has not been opted into.

asset allowlist

within a venue, which markets the agent can touch. example for Hyperliquid:

{
  "venue": "hyperliquid",
  "assets": ["BTC", "ETH", "BNB"],
  "deny": ["MEME", "PEPE"]
}

assets not in the allowlist (and any explicit deny entry) revert at the signer. the allowlist is the source of truth; deny is belt-and-suspenders.

side allowlist

long, short, or both. the constrained launch policy for Sol is long-only for the MVP. shorts are added per-agent on request, with auditing.

leverage cap

maximum leverage per position. the platform ceiling is 5x for any non-stable perp. you can set lower; you cannot set higher without a platform-side override.

{ "maxLeverage": 5 }

if the LLM tries to open a 10x BTC long, STEWARD rejects the sign.

position size cap

maximum USD notional per open position. enforced at signing time using the venue’s mark price oracle.

{ "maxPositionUsd": 100 }

open positions cap

maximum number of concurrent open positions across all venues.

{ "maxOpenPositions": 3 }

reduces the blast radius if the agent enters a feedback loop.

daily open budget

maximum new notional opened per UTC day. closing existing positions does not count against this. only opens.

{ "dailyOpenBudgetUsd": 300 }

if the agent opens

250 of BTC at 06:00 UTC and then tries to open

100 of ETH at 14:00 UTC, the second open reverts (would exceed $300 cap). the budget resets at the next UTC midnight.

loss cooldown

if realized PnL across the agent’s trading day drops below a configured floor, all new opens are blocked until UTC rollover. closes are always allowed.

{
  "lossCooldownUsd": -50,
  "lossCooldownWindowSec": 86400
}

prevents the LLM from doubling down after a bad trade.

address allowlist (for spot)

for venues that use approvals or arbitrary third-party calls (PCS swaps, bridges, ERC-20 transfers), the policy carries an address allowlist of permitted counterparties.

{
  "approveAllowlist": [
    "0x10ED43C718714eb63d5aA57B78B54704E256024E",
    "0xbb4CdB9CBd36B01bD1cBaEBF2De08d9173bc095c"
  ]
}

addresses not on the list cannot receive an approve or a transfer from the agent’s wallet.

time windows (optional)

restrict signing to specific UTC hour ranges. useful if the agent strategy only operates during, say, US market hours.

{ "allowedUtcHours": [13, 14, 15, 16, 17, 18, 19, 20] }

an attempt to open outside the window reverts at the signer.

how policy lives, in code

STEWARD policy engine
   ├── venue-allowlist evaluator
   ├── asset-allowlist evaluator
   ├── leverage-cap evaluator
   ├── position-size-cap evaluator
   ├── open-positions-cap evaluator
   ├── daily-budget evaluator
   ├── loss-cooldown evaluator
   ├── address-allowlist evaluator
   └── time-window evaluator

every signing call runs through the evaluator chain. one rejection short- circuits the whole call. acceptance emits policy.applied. rejection emits policy.denied. both flow into agent_events. read the activity feed with eventType=policy.applied or policy.denied to see exactly what the policy let through (or didn’t).

setting policy

today, policies are set on the agent’s settings page on waifu.fun. each field has a UI control. the page validates against the platform ceiling before persisting. once saved:

waifu.fun PUTs the policy to STEWARD
STEWARD versions the policy (each save mints a new policy id)
the runtime container picks up the new policy on its next signing call
previously open positions are not affected (close is always allowed regardless of policy version)

policies cannot be edited in flight on a single signing call; the signer takes the version it was issued when the request started.

reading policy

on the dashboard:

the trading panel shows the active policy in plain language
the activity feed with category=trading filter shows every sign decision

via API:

GET /v2/agents/:id includes the active policy snapshot
GET /v2/agents/:id/events?eventType=policy.applied for the full audit trail

platform ceilings

primitive	platform max
`maxLeverage`	5
`maxPositionUsd`	$5,000 (MVP cohort; higher tiers TBD)
`maxOpenPositions`	10
`dailyOpenBudgetUsd`	$10,000 (MVP cohort)
venues	`hyperliquid`, `pancakeswap-v2`

these will lift as the platform matures, the audit ships, and venue adapters extend. set yours below the ceiling; you can revise upward on the settings page.

auditing your policy

every six hours, the platform’s auditor sweeps policy.applied events against the policy snapshot. discrepancies (signed actions that violate the snapshot) are flagged in the dashboard’s anomaly panel. there have been zero anomalies since launch; the auditor exists to prove the bound.
