aelf's blockchain halted block production for roughly seven days after malicious smart-contract activity forced a controlled recovery, with 155 flagged transactions tied to the incident (127 on AELF, 28 on tDVV). The Sept. 14 update restored public node access and several core services, including the aelfscan explorer, FairyVault transfers, Awaken trading, Forest NFT browsing and the TMRW DAO staking interface. The reopening does not undo the cost: aelf confirmed no network staking rewards were generated during the halt, so there is nothing from the paused period left to claim.
Why it matters
A week-long outage on a live mainnet is structural, not cosmetic. The five .NET assemblies aelf identified are capable of interacting with host systems and node-related keys and configuration, meaning the attack surface extends past the smart contracts themselves. aelf cautioned that those capabilities do not prove every payload executed or every credential was obtained, but unresolved node and infrastructure credential exposure is what keeps risk live after block production resumes. The post-incident review, technical appendix and independent root-cause assessment remain unpublished.
Market impact
The exchange footprint is uneven. Bithumb scheduled ELF deposits and withdrawals for Sept. 14 at 14:00 KST, MEXC scheduled its resumption earlier and required new deposit addresses, while INDODAX's Sept. 2 notice still described ELF wallet services as closed. For stakers, the loss is already locked: no rewards accrued during the halt, and the restored TMRW DAO interface does not backfill them. For the broader ELF market, a week of zero block production on a chain that sells itself on staking yield is a credibility hit that no restoration timeline can immediately offset. MainChain and tDVV status endpoints were reachable as of Sept. 15 with advancing block heights, but aelf's own checks did not test end-to-end transfers, trades or reward claims, leaving functional recovery partially unverified at the application layer.
Frequently asked questions
-
How long was the aelf blockchain halted?
Block production was paused for approximately seven days following malicious smart-contract activity, with public node access and several core services gradually restored starting Sept. 14.
-
Did aelf stakers lose their rewards during the outage?
Yes. aelf confirmed no network staking rewards were generated during the halt, and restoring the TMRW DAO staking interface does not backfill the missed period.
-
How many malicious transactions were linked to the aelf incident?
aelf's Aug. 26 update identified 155 transactions associated with the malicious activity, 127 on AELF and 28 on tDVV.
-
Were ordinary aelf users' assets stolen during the outage?
As of aelf's Aug. 26 evidence review, no unauthorized transfers of ordinary users' assets or exposure of ordinary-user wallet keys had been confirmed, though node and infrastructure credential exposure remained unresolved.
-
When can users withdraw $ELF from exchanges?
Resumption varies by venue. Bithumb scheduled ELF deposits and withdrawals for Sept. 14 at 14:00 KST, MEXC restarted earlier with new deposit addresses, and INDODAX's Sept. 2 notice still listed ELF wallet services as closed.
