Stablecoin blacklist activity reached unprecedented levels in 2025, and early 2026 data suggests the trend is accelerating. This report provides an overview of aggregate blacklist statistics across major stablecoin issuers and chains, year-over-year trends, and the key takeaways for compliance teams, researchers, and individual users. All figures are approximate and based on on-chain event analysis across Eagle Virtual's supported chains.
A stablecoin blacklist is a mechanism built into token smart contracts that allows issuers to freeze specific wallet addresses, preventing them from sending or receiving tokens. When an address is blacklisted, its funds become immovable on-chain. This report examines the scale and patterns of these enforcement actions across major issuers. For a detailed explanation of how blacklists work at the contract level, see our guide on how stablecoin blacklists work.
Executive Summary
This report summarizes Eagle Virtual's indexed on-chain blacklist dataset as of March 2026. Three themes stand out: higher freeze volume, broader multi-chain coverage, and more visible coordination between token issuers and law enforcement or incident response. The figures below are rounded public summaries of our own indexed counts, not universal industry totals.
Key findings at a glance:
- In Eagle Virtual's indexed dataset, blacklist, freeze, and sanctions enforcement events across tracked issuers and chains surpass 7K+ cumulatively through March 2026 on Ethereum alone.
- Year-over-year event counts indicate continued growth in new blacklist actions, with the rate varying by issuer and chain.
- Ethereum and Tron remain the dominant chains for freeze activity, but L2 chains (Arbitrum, Optimism, Base) are growing rapidly as stablecoin usage migrates.
- Issuer response windows during incidents can be narrow, making continuous monitoring more important than periodic checks.
Aggregate Blacklist Statistics by Token
The following table summarizes approximate blacklist, freeze, and sanctions event counts by stablecoin token on Ethereum (chain 1). These figures represent cumulative distinct risk events recorded on-chain through Q1 2026.
| Token | Approx. Events | Category | Primary Chains |
|---|---|---|---|
| USD0 | ~3,000 | Blacklist | Ethereum |
| USDT | ~1,500 | Blacklist | Ethereum |
| bCSPX / bIB01 / bCOIN | ~600 | Sanctions | Ethereum |
| XSGD | ~595 | Blacklist | Ethereum |
| WLFI / cbBTC / cbETH | ~570 | Blacklist | Ethereum |
| PAXG / PYUSD / USDP / BUSD | ~325 | Freeze | Ethereum |
| USDC | ~230 | Blacklist | Ethereum |

Year-over-Year Trends
Blacklist activity has followed a clear upward trajectory since stablecoins first deployed freeze capabilities. The growth pattern reflects both the expanding use of stablecoins and the increasing maturity of issuer compliance programs.
2020–2022: Foundation Phase
In the early years, blacklist events were relatively rare. Tether, the first major issuer to use its blacklist capability at scale, accounted for most of the early activity. The August 2022 Tornado Cash OFAC designation marked a turning point, prompting a step-change in how issuers, exchanges, and compliance teams treated sanctions-linked exposure.
2023–2024: Acceleration Phase
Freeze activity roughly doubled year over year during this period. Several factors drove the acceleration: increased law enforcement cooperation, growing regulatory clarity (the EU's MiCA framework, proposed US stablecoin legislation), and a series of high-profile hacks that prompted rapid freeze responses. The number of chains where blacklist events occurred also expanded as issuers deployed on L2 networks and additional L1 chains.
2025–2026: Maturity Phase
The current period is characterized by institutionalized compliance. Issuers have dedicated compliance teams, established processes for handling law enforcement requests, and automated systems for detecting and responding to on-chain threats. The growth rate remains high in absolute terms, though percentage growth has begun to moderate as the base grows larger.
A notable development in this period is the emergence of coordinated multi-issuer freezes, where Tether and Circle both act on addresses linked to the same incident within a short time window. This pattern is consistent with tighter coordination among issuers, exchanges, and law enforcement. Our stablecoin freeze case studies examine several of these coordinated responses in detail.
Chain-by-Chain Breakdown
Blacklist event distribution across chains reflects where stablecoin activity is concentrated. For a live view of Eagle Virtual's chain coverage, see our supported chains page.
- Ethereum: The highest event volume overall, reflecting its position as the primary chain for institutional stablecoin activity. Both USDT and USDC blacklist events are most concentrated here.
- Tron: The second-largest chain for freeze events, driven primarily by USDT. Tron carries a significant share of USDT's total supply, particularly in regions where it is used for peer-to-peer payments and remittances.
- BNB Chain (BSC): Moderate blacklist activity, primarily USDT and BUSD. BUSD events are declining as Paxos winds down the token.
- Polygon: Growing blacklist activity, particularly for USDC, as the chain gains DeFi and payment usage.
- Arbitrum, Optimism, Base: Rapidly growing from a small base. As more stablecoin volume migrates to L2 networks, blacklist events are increasing proportionally. These are the fastest-growing chains for new enforcement events.
- Avalanche: Moderate activity, with events tracked across USDT and USDC deployments.
L2 enforcement is the emerging frontier
As stablecoin activity shifts to Layer 2 networks, compliance monitoring must follow. Organizations that only screen on Ethereum and Tron risk missing significant blacklist events on Arbitrum, Optimism, and Base.

Frequently Asked Questions
What is a stablecoin blacklist?
A stablecoin blacklist is a list of wallet addresses that a token issuer has frozen at the smart contract level. When an address appears on this list, it cannot send or receive that token. Major issuers including Tether (USDT), Circle (USDC), and Usual Protocol (USD0) maintain active blacklists. See our full explanation of stablecoin blacklists for more detail.
Which stablecoin has the most blacklisted addresses?
As of Q1 2026 on Ethereum, USD0 leads with approximately 3,000 blacklist events, followed by USDT with approximately 1,500 events. However, USDT has a larger total count when including Tron and other chains where it is also widely deployed. See the aggregate statistics table above for the full breakdown.
How quickly can stablecoin issuers freeze funds?
Issuer response times vary, but recent incidents show freezes can occur within hours of a security event or law enforcement request. This speed makes continuous, real-time monitoring essential rather than periodic batch screening. Our freeze case studies document several rapid-response examples.
Do stablecoin blacklists work across all blockchains?
Each blockchain deployment has its own independent blacklist contract. An address blacklisted on Ethereum is not automatically blacklisted on Tron or Arbitrum, though issuers increasingly coordinate cross-chain enforcement. Monitoring across all chains where a stablecoin is deployed is necessary for complete coverage. Eagle Virtual tracks blacklist events across multiple chains to address this gap.
Methodology and Data Access
This report is based on on-chain event data indexed by Eagle Virtual on Ethereum
(chain 1). Risk events are identified by monitoring known
issuer contract addresses for
specific event signatures (e.g., AddedBlackList, Blacklisted,
Frozen, AddedToSanctionsList). Events are deduplicated by
contract and target address.
All figures are approximate and should be treated as estimates. Exact counts may vary depending on how events are counted (per-address vs. per-transaction), which contracts are included, and the time window applied. Eagle Virtual provides programmatic access to this data through its API for organizations that need exact figures for their own research or compliance programs.
