What’s actually slowing this PC down?

Before sending USDC, USDT, or another stablecoin, verify the complete recipient address using a trusted source, confirm the exact token and network the recipient accepts, and review the wallet’s final transaction summary. A correct-looking address or familiar ticker alone is not enough. Once a blockchain transfer is confirmed, it generally cannot be reversed by the wallet or issuer.
Verify the recipient address in full
Get the destination from the intended recipient or an address-book entry you previously verified. Do not rely only on a destination copied from recent transaction history: address-poisoning attacks can place a lookalike address in that history, sometimes after sending a tiny unsolicited transfer.
Compare every character of the destination with the trusted original. Matching only the first and last characters is not sufficient because an attacker can make the beginning and ending look familiar while changing the middle. If your wallet truncates the address, open its full-address view before approving. The FBI advises: “To protect yourself, check the entire cryptocurrency address to ensure it fully matches the address where you want to send funds.” (FBI Denver Field Office, April 26, 2024.)
An unexpected small transfer or token is not evidence that its sender is your intended recipient. If an address or token looks suspicious, the FBI recommends checking it in a public blockchain explorer; an explorer can help you inspect public records, but it does not establish that an address belongs to the person you intend to pay.

Confirm the stablecoin and network with the recipient
Ask the recipient which exact stablecoin and network they accept. Check both in your wallet’s send flow. “USDC” or “USDT” in the ticker field does not, by itself, prove that the chosen token representation is compatible with the recipient’s wallet or service.
Stablecoins with the same name may exist on different networks. Avalanche Support, for example, distinguishes stablecoin versions on Avalanche and Ethereum and warns that an incompatible transfer may be permanently lost. Confirm the receiving service’s supported asset and network rather than assuming that a matching ticker or a valid-looking address is enough. (Avalanche Support.)

Check the token contract or mint when relevant
Token names and symbols can be imitated. On Solana, verify a token’s mint address against an authoritative issuer or network source; Solana’s production-readiness guidance warns that a spoofed token can use the same name and symbol as a legitimate one while having a different mint. (Solana documentation.)
The mint check is specific to Solana. On other networks, use the authoritative contract-address source for that chain or the token issuer. Do not treat a wallet’s displayed name or ticker as proof of authenticity.

Review the final send screen before approval
Immediately before signing or confirming, check the wallet’s final summary against the intended payment. Wallets use different labels and layouts, but look for:
- Recipient: the complete address matches the trusted destination.
- Asset and network: the exact stablecoin representation and network match what the recipient accepts.
- Amount: the amount the recipient is expected to receive is correct.
- Fee and total: the network fee and total debit are acceptable.
Tether Wallet documents a pre-approval summary showing the amount sent and network fee, and states: “Once confirmed, transactions cannot be reversed.” (Tether Wallet.) Other wallets may show different details, so check the fields available in the wallet you are using. If anything differs from your instructions, cancel rather than trying to correct it after sending.

When to send a test transaction
For a substantial payment to a new destination, a small test transfer can be useful after the address, token, and network have all passed the checks above. Wait for it to confirm, then verify with the recipient through a trusted channel that it arrived as expected before sending the remaining amount. Avalanche Support suggests a test transfer when in doubt, while also warning that an incompatible transfer can be permanently lost. A test is not a remedy for an unsupported network, and it does not make the larger transfer reversible.

Two-step verification can protect an account action, but it does not independently verify the recipient address or token. Coinbase says two-step verification is required for each stablecoin send in its EU/EEA context; that platform- and region-specific rule should not be assumed to apply to every wallet. (Coinbase Help.)

A hardware wallet with an on-device display can provide another place to review the address while signing, but it cannot eliminate every transfer risk. Manually checking long addresses is difficult, so compare the full string with the trusted source rather than assuming that a device or wallet will catch a lookalike.
If you are unsure, stop and verify separately
Do not approve a transfer while the address, token, network, amount, or fee remains uncertain. Contact the recipient using a separate channel you already trust—for example, a known phone number or established conversation—not contact details supplied only alongside a suspicious payment request. Resume only when the details match. If a transfer is already confirmed, contact the recipient or the relevant platform promptly, but do not assume the wallet issuer can reverse it.
Why these checks matter
In an April 26, 2024 advisory, the FBI Denver Field Office described one Colorado victim who lost $2.1 million in a stablecoin investment scam involving impersonation tokens. That is a single reported incident, not a measure of how often address poisoning occurs. The practical lesson is to verify the destination and the asset independently rather than trusting a familiar-looking history entry or token label.
