Note

Arweave is built so stored data stays available permanently, so never upload personal information or wallet files you may later want removed. Individual miners and gateways can refuse to store or serve content, but no single party controls the network.

How to check an Arweave address

  1. Get the public addressAsk your counterparty for the address they will send from — or copy it from the incoming transaction.
  2. Pick a service that covers ArweaveChoose one marked “Supported” in the list above. Copy and paste Arweave addresses instead of typing them. They are case-sensitive, so one wrong capital letter means a different address.
  3. Run the check and read itTreat your wallet's JSON keyfile like a password: keep a secure offline backup, and never share it or upload it anywhere.
A real AML check needs only a public address. Never share a seed phrase or private key.

Arweave specifics

  • Arweave describes its model as 'pay once, store forever': you pay a single upfront fee and the network is designed so stored information cannot be lost, censored, or controlled by any single entity.[1]
  • Fees are paid in AR, and amounts are often shown in winston, the smallest unit: 1 AR equals 1,000,000,000,000 winston.[2]
  • Many uploads are 'bundled' under the ANS-104 standard: lots of separate data items are packed into one transaction whose fee can be paid by a third party, and these data items cannot transfer AR tokens.[3]
  • Arweave addresses are always 43 characters: the ecosystem converts Ethereum- and Solana-style signer keys into this same format, so an address that looks like Arweave's may come from another chain's key.[4]
  • There is no central moderator: each miner can apply its own 'content policy' to refuse storing data that may be illegal in its country, and Arweave's team offers a ready-made filter.[5]
  • On the AR.IO gateway network, which serves Arweave data to users, each gateway can voluntarily blocklist any content, name, or address that breaks its policies or local regulations.[6]

Common risks on Arweave

FAQ

What does an Arweave address look like?

A 43-character string of letters, numbers, '-' and '_', with no fixed prefix. It is derived from the wallet's public key, and upper and lower case matter.

Can data stored on Arweave be deleted?

Arweave is designed for permanent storage ('pay once, store forever'), with no central operator. Individual miners and gateways can choose not to store or serve specific content, but you should assume anything uploaded stays available.

Is there native USDT or USDC on Arweave?

No. As of 4 October 2026, neither Tether's nor Circle's official lists include Arweave, so any token on Arweave calling itself USDT or USDC is not issued directly by Tether or Circle.

How do I check a Arweave address for AML risk?

Copy the public address, open one of the services listed above that supports Arweave, and run the check. You never need a seed phrase or private key.

What does “Not verified” mean?

The service claims support somewhere — in marketing copy or a third-party page — but its own docs, pricing or FAQ do not list the network. Treat it as unknown.
