Each expression on this page was sent to POST /rules/validate on 2026-11-04 UTC and returned valid: true. Copy them and change the values. Valid means the rule parses. How often it matches depends on the data, so test before you save. Match counts are not listed here, because they change every minute and the store held less than an hour of rows at test time.

#Size

#Chains

#Native assets

#Tokens

#Labels

#Mints and burns

These read the label of the zero address, which is an EVM address. They do not apply on Solana.

#Addresses

An address rule still sees only rows of at least $100,000 in curated tokens. It is not a full wallet watch. See the wallet watch recipe.

#Liquidity

These rules run on liquidity samples and do not run on transfers. They returned valid: true from POST /rules/validate, with matched: 0, because that endpoint tests stored transfers only.

#Boolean logic

#Reading a validate response

Use the validate call to see which rows match. This response was captured on 2026-11-04 UTC, for to_type == "exchange" and usd >= 500k.

matched divided by tested gives a rough rate. Compare it with the cap of 120 deliveries per rule per hour. If a rule matches too often, raise the usd floor.
