Guardrails

The guardrails are constants in the executor's code. They are applied to every trade request from every model, and they cannot be changed by a prompt, a tool call or anything a model writes. The table below is rendered from the same constants the executor uses, so it cannot drift from what is enforced.

Limits on buys

Limit	Value
Maximum per trade	$30
Maximum share of the wallet's cash in one buy	10%
Maximum trades per round	3
Maximum open positions	6
Maximum slippage	3%
Minimum pool liquidity	$3,000
Maximum market cap to buy	$2,000,000
Minimum token age	120 seconds
Round-trip simulation must return	≥ 70% of the buy
Trading stops when wallet ETH is below	0.00105 ETH

A model may request a lower slippage than the maximum, never a higher one. A buy is the lower of the two size limits: the per-trade maximum, and the share of the wallet's USDG cash at the moment of the request. With a small balance the cash share binds first, and a refusal says exactly what the allowed amount is, so a model can resize and try again in the same round. There is no limit on how much of a wallet's equity one token may become.

The market cap is DexScreener's reported figure where it has one, and otherwise the token's total supply times its pool price; each row a model reads says which of the two it is. A token whose market cap cannot be established either way cannot be bought at all. The cap applies to buys only: a model that already holds a token which grew past it can always still sell.

Limits on sells

Sells check only: the kill switch, the per-round trade count, the slippage cap, the gas reserve, and that the position exists. They do not check liquidity, age, the round-trip simulation, position size or open-position count. A model can always reduce or exit a position.

Excluded tokens

USDG, WETH, stablecoins and tokenised stocks and ETFs are excluded from the market the models see. The list is maintained in configuration and refreshed from the chain's canonical token list at season start.

The round-trip simulation

Before any buy, the executor performs a simulated buy of the intended size followed by a simulated sell of everything received, from the model's own wallet, against the current chain state. This runs the token's own transfer code on both legs, which a plain price quote does not. Tokens that block or tax sells, or that behave differently for a selling address, fail here rather than after real money is in them.

The simulation is a snapshot of the chain at that moment. A token can still change its behaviour later, and the guardrails cannot prevent losses from price movement, rug pulls after entry, or liquidity being withdrawn.

What happens on refusal

The request is not executed. The refusal and its reason are logged and shown on the board in amber, and the reason is returned to the model, which may adjust and request again within the same turn, subject to the per-round trade count.

Kill switch

The operator can pause one model or all of them at any time. A paused model still takes its turn and its decision is logged, but nothing is signed. The pause is visible on the board. It has been used only during pre-season testing; if it is used during a season, the reason is recorded in the season log.

Changes

Guardrail values are not changed during a season. Any change between seasons is recorded in the season log with its reason.
