When Anchorage Digital receives a crypto deposit that can’t be automatically attributed to a known sender, one or more authorized users are notified by email to identify the sending party. Adding addresses to your trusted sources speeds up future attribution, but it’s optional — you can always attribute a deposit after it arrives. A pending attribution holds only that deposit. It doesn’t block your other funds, and the address can continue receiving deposits as usual.
Trusted sources and deposit attribution apply to crypto deposits only. USD (fiat) deposits arrive as wire transfers and are identified by the sender’s bank information — no attribution step is required.

​
Trusted sources

Trusted sources allow future deposits from known addresses to be automatically attributed without manual review. Once you add an address as a trusted source, deposits from that address are attributed automatically.

​
Adding a trusted source

1

Navigate to trusted sources

Go to Settings and select Trusted sources, then select Add trusted source.
2

Enter address details

Enter the address details when prompted and confirm the information is accurate.
3

Confirm

Select Add trusted source. Future deposits from this address are attributed automatically.

​
Editing or removing a trusted source

Select the three-dot menu to the right of any trusted source address to edit or remove it.

​
When to use trusted sources

  • Frequent counterparties — Add addresses from your regular transaction partners
  • Internal transfers — Add your own deposit addresses to skip attribution prompts
  • Institutional relationships — Pre-add addresses from banks or other institutions you receive funds from regularly

Deposit attribution

​
Viewing and attributing pending deposits

1

Access pending attributions

After logging in, select Attribute deposits from the homepage, or navigate to the Operations tab.
2

Select a deposit

Select the deposit you want to attribute and select Attribute deposit. You may attribute multiple deposits simultaneously if they share the same originator(s).
3

Add originator details

Enter the name and country of the originator. You may add multiple originators. To automatically attribute future deposits from the same address, check Add to your trusted sources.
4

Confirm

Confirm the information is accurate and select Attribute deposit. Once attribution is complete, the associated amount becomes available for withdrawal.
If you don’t recognize a deposit, you have the option to flag it as spam.
Until you attribute the originator and screening clears, an unattributed deposit appears in your total balance but isn’t available to withdraw. A received or “complete” deposit isn’t the same as available funds — attribution is what releases them.
Prompt action on deposit attribution requests helps avoid withdrawal delays for deposits that can’t be automatically attributed.

​
Spam and dust deposits

Unsolicited deposits — spam tokens, dust amounts, or transfers from spoofed counterparties — still enter the attribution queue and are reviewed by our compliance team like any other deposit. They don’t put your genuine funds at risk. If you receive a deposit you don’t recognize, leave it unattributed and don’t interact with it. Flag it as spam so our team can review it. For deposits designed to imitate addresses you already use, see address poisoning protection.

​
Best practices

  • Verify sender information — Confirm the originator name and country match your expected counterparties
  • Use trusted sources — Add frequently-used addresses to trusted sources to streamline future deposits
  • Review regularly — Check for pending attributions regularly to avoid delays in withdrawal availability
