Rules

A rule narrows a watch so you only hear about what matters. Every field is optional; an empty rule {} fires on any transfer of the watched token.

{
  "direction": "in",
  "minAmount": "1000000000",
  "maxAmount": "5000000000000",
  "counterpartyIn": ["0xpartner…"],
  "counterpartyNotIn": ["0xexchange…"]
}

Field	Type	Meaning
`direction`	`in` \| `out` \| `any`	Incoming, outgoing, or both (default `any`).
`minAmount`	string	Fire only at or above this amount.
`maxAmount`	string	Fire only at or below this amount.
`counterpartyIn`	string[]	Only when the other party is in this list.
`counterpartyNotIn`	string[]	Never when the other party is in this list.

Unknown fields are rejected — rules are validated strictly.

Amounts are raw base units

Amounts are integer strings in the token’s smallest unit, never decimals. This avoids floating-point error and matches the chain exactly. Multiply the human amount by 10^(token decimals):

You want	Token (decimals)	`minAmount`
≥ 10,000 USDT on TRON	USDT-TRC20 (6)	`"10000000000"`
≥ 10,000 USDT on BSC	BSC-USDT (18)	`"10000000000000000000000"`

The same raw-unit amount is echoed back in every alert payload.

Counterparties are matched case-insensitively, the same way addresses are.
