Freeze Events by Year
Stablecoin freeze activity has grown substantially each year since issuers first began using their blacklist capabilities. The table below shows approximate enforcement event counts by year across all monitored tokens.
| Year | Blacklist Events | Unblacklist Events | Fund Destructions | Trend |
|---|---|---|---|---|
| 2020 | ~150 | ~10 | ~5 | Baseline year |
| 2021 | ~400 | ~20 | ~15 | +167% YoY |
| 2022 | ~800 | ~40 | ~30 | +100% YoY |
| 2023 | ~1,500 | ~60 | ~50 | +88% YoY |
| 2024 | ~2,500 | ~80 | ~70 | +67% YoY |
| 2025 | ~3,000 | ~100 | ~80 | +20% YoY |
All figures are approximate and rounded. Includes blacklist, freeze, pause, and access-control events across all monitored tokens. 2025 data is partial (through Q4).
Freeze Events by Token
USDT accounts for the majority of blacklist events, reflecting both its market dominance and Tether's willingness to act on a broader range of requests. USDC represents the second-largest share, with other token issuers contributing smaller volumes.
| Token | Issuer | Total Events (All Time) | Share of Total |
|---|---|---|---|
| USDT | Tether | ~5,500 | ~65% |
| USDC | Circle | ~1,200 | ~14% |
| BUSD | Paxos | ~400 | ~5% |
| TUSD | Techteryx | ~200 | ~2% |
| Other tokens | Various (35+ issuers) | ~1,200 | ~14% |
Totals are approximate. "Other tokens" includes RWA tokens, wrapped assets, and smaller stablecoins with enforcement capabilities.
Freeze Events by Chain
Ethereum and Tron dominate freeze activity, reflecting the concentration of stablecoin circulation on these two networks. L2 chains and newer deployments account for a growing but still smaller share.
| Chain | Total Events | Primary Tokens |
|---|---|---|
| Ethereum | ~3,500 | USDT, USDC, BUSD, TUSD |
| Tron | ~2,800 | USDT |
| BNB Chain | ~800 | USDT, BUSD |
| Polygon | ~400 | USDT, USDC |
| Arbitrum | ~250 | USDT, USDC |
| Avalanche | ~150 | USDT, USDC |
| Optimism | ~120 | USDT, USDC |
| Base | ~80 | USDC |
All figures are approximate. Chain totals include events across all tokens on that chain.
Key Observations
Enforcement Is Accelerating
The year-over-year growth in blacklist events shows no signs of slowing. As stablecoin adoption increases and regulatory frameworks mature, issuers are receiving and acting on more enforcement requests. The average number of monthly blacklist events has increased roughly 20x since 2020.
Multi-Chain Coordination Is Standard
Issuers now routinely coordinate blacklists across multiple chains for the same target. A single entity may be blacklisted on Ethereum, Tron, and one or more L2 chains simultaneously. This makes cross-chain monitoring essential for compliance teams.
Tron Is Growing Fastest
While Ethereum remains the chain with the most total blacklist events, Tron-based freezes have grown at the fastest rate. This reflects Tron's increasing role in global P2P stablecoin transfers, particularly in regions with limited banking infrastructure.
Unblacklisting Is Rare
Fewer than 4% of blacklist events are subsequently reversed. Once an address is frozen, it typically remains frozen permanently. This underscores the importance of pre-transaction screening: once funds are sent to a blacklisted address, recovery is extremely unlikely.
Methodology
All statistics on this page are derived from on-chain event data indexed by Eagle Virtual. We monitor smart contract events including AddedBlackList, Blacklisted, Frozen, Paused, and related enforcement events across 41+ token contracts across supported chains. That coverage includes dollar stablecoins, euro-denominated assets such as EURC, EURe, and agEUR, and Brazil-focused activity such as BRZ where applicable. Figures are rounded to the nearest approximate value and are updated periodically. These are not real-time counts.
Dollar values for frozen assets are estimates based on token quantities at the time of freeze, using stablecoin 1:1 USD peg. We do not estimate dollar values for non-stablecoin tokens without verified price data.

Regulatory Context
MiCA (EU): For MiCA-focused teams, stablecoin monitoring and evidence retention are part of a broader compliance program. Eagle Virtual tracks freeze, blacklist, and seizure events in real time across supported chains for EURC, EURe, agEUR, and related stablecoin flows.
Brazil (BCB): Brazilian SPSAVs must monitor stablecoin transactions under BCB Resolution 521. With 90% of Brazil's crypto activity involving stablecoins, enforcement tracking is essential for BRZ, USDT, and USDC flows.
