Why set it up
Why people watch it
Whale moves only
1M USYC or more per transfer: the moves of funds and treasuries, not the noise.
Straight from the contract
Each alert is the USYC token's own Transfer event, with the transaction.
Within seconds
You see the move when the block is confirmed, not in a weekly report.
Explained
Why large transfers, not mints and burns?
Circle publishes the USYC addresses but not its contract source, so we can't confirm what a USYC mint or burn logs beyond the standard Transfer event. The ready-made rule uses that event: every transfer of 1M USYC or more, whatever its direction. New USYC issued in size and USYC redeemed in size show up too, as transfers from or to the zero address.
Explained
Who moves USYC?
USYC is held by institutions outside the US. A large move can be a holder rebalancing, a move between its own wallets, or USYC on its way to redemption. The alert shows the amount, the sender and the recipient; the reason is not on-chain.

FAQ
Frequently asked questions
Where does the data come from?
Every alert comes from the token contract's own event on Ethereum mainnet, read within seconds of confirmation, with a link to the transaction on Etherscan.
Can I change the 1M minimum?
Yes. The rule opens with 1,000,000 USYC as the minimum; change it in the form before you click Create.
Can I set this alert for free?
Yes. The free Beta plan covers one contract and needs no card, so any one of these rules fits in it.
Do the alerts show prices or USD values?
No. Amounts are in token units, as the contract records them. Alerts carry no USD value and no price.
Is Alerts on Chain affiliated with Circle?
No. Alerts on Chain is not affiliated with Circle. The rules read public on-chain data from the contract Circle publishes.
Does it cover other chains?
Ethereum mainnet only. Some of these tokens also live on other chains, each with its own contract; the rules here cover the Ethereum contract.
