Why are address poisoning attacker able to send fake token out of my account?

I am used to address poisoning. Whenever I send/receive token, I will then receive some random tokens from addresses that has the same starting and ending sequence as the address I interacted with.

But I see something I can't explain. Whenever I send X amount of USDT, My address also send the exact same amount of fake USDT to an address mimicing the receiving address.

How can the attacker use my account to send a token I don't even know I have?

On Etherscan, the sender address is clearly my address, but if they already control my accout, poisoning the receiving address is pointless. They can just steal my funds. If they don't control my accout, how did they send fake token from my account?

What is the biggest thing preventing Ethereum from becoming an everyday payment network?

Ethereum has fast L2s, stablecoins and a much better user experience than it did a few years ago, yet most people still don't use it for everyday payments.

What's the biggest thing holding it back?

I'm curious to hear what everyone thinks. Thanks

A job for Ethereum: StubHub sold ‘ghost tickets’ for World Cup months before real ones were issued

One day the world will wake up and see Ethereum as fraud prevention instead of fraud. When I read this article about World Cup fans being sold $10,000 tickets that don't exist, I immediately realized this would never happen on Ethereum. Tickets could be NFTs locked into smart contracts. It's such a perfect fit. Hope it happens some day!

Ethereum has just closed its strongest quarter in history.

During Q2 2026, the network processed 203,851,942 transactions, setting a new all-time high for quarterly onchain activity.

This milestone is significant because transaction count remains one of the most reliable indicators of real network utilization.

What's particularly noteworthy is that this record comes more than a decade after Ethereum launched. As blockchain ecosystems mature, sustaining growth becomes increasingly difficult. Yet Ethereum continues to expand its activity despite an already massive user base and one of the largest application ecosystems in crypto.

The result also reflects years of continuous protocol improvements. Upgrades focused on scalability and data availability, combined with the rapid growth of Layer 2 networks, have allowed Ethereum to support significantly higher throughput while maintaining its role as the ecosystem's settlement layer.

A huge thank you to the developers, validators, builders, researchers, and millions of users who continue contributing to the network every day. Milestones like this are only possible because of the strength of the broader Ethereum community.

Has anyone dealt with verifying the source of funds before depositing crypto to Bitpanda?

Here's my situation:

I bought most of my BTC, ETH, and other cryptocurrencies back in 2016/2017. At that time, I purchased them on several different exchanges, many of which no longer exist (some have shut down or gone bankrupt). Over the years, the coins were moved between multiple exchanges and wallets.

Since around 2022, all of my coins have been stored on my Ledger hardware wallet.

Now I'd like to transfer some of them to Bitpanda, but I'm concerned that the deposit could be flagged due to source-of-funds requirements.

My questions are:

  • Is there a way to verify or pre-approve the origin of my coins before sending them to Bitpanda?
  • Does Bitpanda have a process or contact for this?
  • Has anyone successfully deposited "old" coins from 2016/2017 with a similar history?
  • What kind of documentation did you provide if the original exchanges no longer exist?

I'd rather clarify everything beforehand than send the coins and risk having the deposit delayed or frozen while trying to provide documents that may no longer be available.

I'd really appreciate hearing about your experiences. Thanks!

Does anyone else hold crypto but rarely spend it?

I've noticed something funny. A lot of people talk about crypto adoption, but most crypto holders I know barely spend any of it.

Recently, I started exploring ways people use crypto outside of exchanges.

It made me realize that most of us probably don't spend crypto simply because we don't think about it. Not because there aren't options.
I'm just curious where people stand on this.

Do you actively spend crypto or is it mostly something you hold long-term?

PoolTogether is looking for more community members

Hello, r/ethereum!

I'm a member of the PoolTogether community. PoolTogether is a DeFi protocol that's been around for a long time; Ethereum oldheads might remember the name from as far back as 2019. The protocol works by users depositing their yield-bearing tokens, then their pool of yield being randomly awarded as prizes among the depositors. It incentivizes responsible saving by giving it some of the excitement of gambling, but without any of the degen risktaking--users never lose what they deposited and can withdraw at any time.

Right now we're gearing up to have a giveaway of free chances to win on Base, where the total prize pool is currently 3.9 WETH. All you have to do to be eligible is join our Discord server and subscribe to our notification bot, Tooly. The winner of this giveaway will be selected this Thursday, July 2nd.

What is the Ethereum Glamsterdam Upgrade? Everything You Need to Know

Key Takeaways

  • Glamsterdam is Ethereum's next major hard fork, combining the Amsterdam (execution layer) and Gloas (consensus layer) upgrades. It is planned for Q3 2026, though the exact timeline remains subject to devnet testing progress.
  • Parallel transaction processing arrives via EIP-7928 (Block-Level Access Lists). Nodes can now see which transactions do not conflict and process them simultaneously, laying the groundwork for significantly higher gas limits.
  • Third-party relays are no longer required. EIP-7732 enshrines proposer-builder separation directly into the protocol, reducing centralisation risk and expanding the block propagation window from 2 seconds to roughly 9 seconds.
  • State creation and access get repriced. EIP-8037 introduces a cost-per-state-byte model targeting 120 GiB/year growth, while EIP-8038 updates state-access opcode costs to reflect modern hardware. Both changes affect contract deployment and storage-heavy applications.
  • ETH transfers now emit a standard log. EIP-7708 closes a long-standing blind spot: every non-zero ETH transfer or burn will produce a trackable event, removing the need for custom tracing in bridges, exchanges, and wallets.
  • Cross-chain address consistency is solved. EIP-7997 mandates a universal CREATE2 factory across all participating EVM chains, giving developers deterministic addresses without chain-specific deployment scripts.
  • No action required for ETH holders. Balances and existing contracts are completely unaffected. Node operators and stakers must update client software before mainnet activation.

When your home bank card continues getting denied, what is the simplest way to pay for hotels or Uber overseas?

I frequently experience this when traveling. The transaction is rejected, the card is flagged, and the bank must be contacted from a different time zone. truly draining.

began storing cryptocurrency as a backup just for this purpose. discovered a crypto platform, which offers travel and mobility gift cards that can be purchased using cryptocurrency and sent instantaneously to Hotels.com, Uber, and airline platforms.

Thus, in the event that my card is blocked, I can obtain a Bitcoin or Ethereum gift card and complete the reservation without having to deal with the bank.

Does anyone else use this as a backup plan when traveling? I want to know if this is a frequent workaround or if there are better choices.

Is WBTC safe?

Im considering converting a few BTC to WBTC to stake. Theorically WBTC is better because I can also earn passive income while "holding my keys" which is what i'm trying to understand:

Is this custodial? more risky or same as USDT? Was there any freeze or issue on it by past?

I built a zero-knowledge (ZK) and blockchain-based customs clearance prototype using SP1 zkVM + BLS threshold signatures — looking for feedback on the architecture.

Built a prototype for cryptographically securing customs document clearance.
The core idea: make document manipulation mathematically impossible after ministry approval, without exposing document contents or holder identity.

How the ZK layer works:

The ZK proof is generated inside SP1 zkVM — a RISC-V zkVM that compiles Rust circuits to Groth16/PLONK proofs. The circuit takes the ministry's ECDSA signature and the document hash as inputs, and mathematically proves three things simultaneously:

  1. The document was signed by a legitimate ministry key
  2. The document content has not been altered since signing
  3. The person presenting the document is its rightful holder

All of this is proven without revealing the document contents, the holder's identity, or the ministry's raw signature to any external party. The committee that attests to the proof never sees the underlying data — only the mathematical statement "this is valid."

Domain separation is applied to the document hash: `SHA256("ublp-doc-v1:" + canonicalJson(document))` — preventing cross-protocol hash collisions.

Architecture:

- Ministry signs document (EC P-256 ECDSA) → issues Verifiable Credential
- Agent generates ZK proof via SP1 zkVM (Groth16/PLONK)
- `document_hash` and ministry sig as public inputs
- holder identity as private input → only `holderPubKeyHash` exits the circuit
- Independent committee verifies ZK proof, then BLS12-381 threshold signs (2/3)
- L2 smart contract verifies both ZK proof + BLS signature → immutable settlement

ZK Circuit inputs:

Private (never leaves the circuit):

- ministry_pub_key_raw — uncompressed SEC1, 65 byte
- document_hash — SHA256("ublp-doc-v1:" + canonicalJson), 32 byte
- holder_signature — P-256 ECDSA, 64 byte
- holder_pub_key_raw — uncompressed SEC1, 65 byte
- holder_did — UTF-8 bytesPrivate (never leaves the circuit):
- ministry_signature — P-256 ECDSA, 64 byte

Public outputs (verified by L2):

- document_hash — document fingerprint
- ministry_pub_key_hash — SHA256(ministry raw key)
- document_id_hash — replay protection
- holder_pub_key_hash — holder identity proof; hash only, not raw key

Key design decisions I'd love feedback on:

  1. Agent-first flow: committee never sees raw document, only the proof
  2. Holder privacy: holder sig stays inside circuit, only hash is public
  3. BLS threshold before L2 settlement — is 2/3 the right threshold model?
  4. Domain-separated document hash — is `SHA256("ublp-doc-v1:" + canonicalJson)` the right approach for SP1 use cases?

This is a prototype — mock ZK in dev mode, real SP1 in prod mode.
