3/ ❗️All staked assets on @ankrstaking are secure, and all infrastructure services were unaffected.
4/ A hacker was able to compromise a deployer’s private key after the Ankr team carried out an upgrade (pending law enforcement investigation).
The attacker used the deployer keys to modify the smart contract that allowed for unlimited minting of aBNBc.
5/ They immediately began using DEXs to trade through LPs. Ultimately draining ~$5m USD.
We promptly responded with the help of many DEXs that halted the trading of the aBNB tokens immediately upon discovering the breach.
6/ The only users at risk were liquidity providers. We have started creating a list of the ones affected to make sure that we fully compensate them.
7/ We understand diluted aBNBc was speculatively traded after the exploit occurred, but we are only able to compensate LP’s caught off guard by the event.
8/ Dozens of protocols, customers, and community members offered to help and support. Thank you! 🙏🫡 #wagmi

The team at Ankr has assessed the damage and it is max 5M USD worth of BNB from the liquidity pools.
We are currently working hard to resolve this issue efficiently and we would like to propose the following to address the current situation:
2/ We will take a snapshot and reissue ankrBNB to all valid aBNBc holders before the exploit.
The ankrBNB token will continue to be redeemable, while aBNBc and aBNBb will no longer be redeemable.
3/ Additionally, Ankr will purchase 5m worth of BNB and use this to compensate in totality the liquidity providers that have been affected by the exploit due to the drainage of the liquidity pool.
Our aBNB token has been exploited, and we are currently working with exchanges to immediately halt trading.
All underlying assets on Ankr Staking are safe at this time, and all infrastructure services are unaffected.
Further instructions from the Ankr team: 1. Do not trade 2. Remove liquidity from DEXes if you are a liquidity provider (and keep the aBNBc) 3. Snapshot will be done and wait for additional news 4. Will do a reissuance of aBNBc
2/ Today we are announcing a new nomenclature for our token model that will see the names of reward-bearing tokens change and the complete removal of our reward-earning tokens.
3/ What are the current Liquid Staking tokens offered by @ankrstaking? 🤔
• Reward Bearing Tokens (c-tokens), e.g. aETHc formerly aETH
• Reward Earning Tokens (b-tokens), e.g. aAVAXb and aETHb (formerly fETH.)
