How this service works
Circle USDC and EURC control events on Ethereum, Base and Arbitrum, newest first: blacklistings and reversals, pauses, minter allowances, role changes and proxy upgrades, each with block, time, transaction and address. Since a date (up to 90 days back), filter by chain, token and type, 500 a page. Use to monitor freezes and issuer control actions. From the contracts' own logs, refreshed daily. JSON, no API key. $0.01 per call. Blockchain IQ.
Output
A paginated JSON list of stablecoin control events, each including event type (e.g. Blacklisted, UnBlacklisted, MinterConfigured, Upgraded), block number, block timestamp, transaction hash, and relevant addresses. A nextCursor field is included when more pages are available. Events are sourced directly from on-chain contract logs and refreshed daily.
Example use cases
Compliance monitoring for blacklisted wallets
“Show me all USDC blacklist and unblacklist events on Ethereum and Base over the last 7 days — I need to check if any wallet addresses we interact with have been frozen by Circle.”
Minter allowance audit across chains
“Get me the most recent minter configuration changes for USDC on Arbitrum over the past 30 days — I want to audit which minters have had their allowances changed or removed.”
Stablecoin contract upgrade tracking
“Pull all proxy upgrade and admin change events for EURC on Ethereum since 60 days ago — I'm tracking when Circle has upgraded the EURC contract.”
Technical details
Endpoint
GEThttps://www.blockchainiq.co/api/x402/v1/stablecoins/events?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to monitor or audit Circle's issuer control actions — specifically blacklistings, pauses, minter changes, role updates, or contract upgrades — on USDC or EURC contracts across Ethereum, Base, or Arbitrum. It is the right choice for compliance workflows, wallet screening, DeFi risk monitoring, or on-chain governance tracking. Prefer it over generic blockchain explorers when you need pre-parsed, filtered, and categorized stablecoin control events without writing your own log parsing.
Side effects
- Invalid 'since' date beyond 90 days ago returns an error
- Unsupported chain, token, or type enum values return a validation error
- Invalid or expired cursor returns a pagination error
- No events found for the specified filters returns an empty result set
- Service unavailable or rate limiting returns a non-200 HTTP status
