Stablecoins and Tokens

For issuers, treasuries, and anyone exposed to stablecoins, these rules track the events that matter most: supply changes (mint / burn), issuer freezes, over-exposure to a single issuer, and a stablecoin drifting off its peg.

Rules

🟢 Stablecoin Supply Change

Detects. A supported stablecoin is minted or burned.


Trigger	A `mintTo` / mint or burn of a supported stablecoin whose USD value exceeds a configurable threshold. Coverage spans a set of supported stablecoin mints / contracts.
Account types	Token / mint (stablecoins) + holder addresses
Status	Active

🟢 Stablecoin Issuer Freeze and Blacklist

Detects. A stablecoin issuer freezes (or blacklists) an address, or unfreezes it.


Trigger	A `freezeAccount` on a token account, or an address being added to / removed from a stablecoin blacklist, above a configurable threshold where applicable.
Account types	Token / mint (stablecoins) + token accounts / blacklisted address
Status	Active

🟢 Asset Price Deviation

Detects. A stablecoin’s price drifts off its peg.


Trigger	Cross-checks aggregated pricing against an oracle for supported stablecoins; alerts escalate with the size of the deviation, and emit recovery events when the peg is restored. (Scheduled.)
Account types	Token / mint (stablecoins)
Status	Active

🟢 Stablecoin Issuer Concentration

Detects. Too large a share of a treasury’s stablecoin holdings sits with one issuer.


Trigger	The percentage of stablecoin holdings from a single issuer (e.g. Circle / USDC, Tether / USDT) across monitored treasury wallets exceeds a configurable threshold. (Scheduled.)
Account types	Treasury wallets; token / mint (stablecoins)
Status	Active

⚪ Deprecated rules (migration context)

Retired from a previous runner, kept for completeness:

SPL Token Mint / Burn / New / Freeze: individual SPL token supply and freeze events (superseded by the stablecoin rules above).
Large Memecoin Swap: large memecoin swaps.
HUGE Whale Dump: a whale dumps a large amount of an asset.
Total Asset Holders Change / Limit Crossed: holder count changes by, or crosses, a threshold.
Total Asset Marketcap Change / Limit Crossed: marketcap changes by, or crosses, a threshold.
Risky Total Asset Marketcap Limit Crossed: a risky asset’s marketcap crosses a threshold.
