- Between 5K and 8K affected wallets were affected based on preliminary reports.
- SOL remained above $39, no network outage.
- Solana NFT minting peaked in June and July.
The exploit may be related to a wallet’s function for automated approval. This has allowed exploiters to target wallets previously used for NFT mints or other purchases. In the past, Solana wallets have been targeted through malicious links that called to empty out any NFT and tokens.
Currently, Solana users may be at risk, making the hack especially salient. The Solana ecosystem grew in 2022, adding more NFT and games. Messari reported significant growth and a trend for more collections to use Solana in the past seven months.
It was precisely this boom in NFT usage that left some of the wallets vulnerable. After interacting with minting smart contracts, the wallets had an option to automatically allow the transfer of funds. The hack may be affecting older wallets which have participated in mints in the past. Solana also had a more significant boost in new wallets in the second quarter of 2022.
Move Funds to New Wallets to Protect Tokens, NFT
There is still no detailed report on which NFT have been affected or if the hack targeted those items. NFT are harder to resell compared to fungible tokens, which can be dumped on crypto exchanges.
Despite the hack, the SOL market price remained relatively stable, sliding only about 2.5% in the past day, to a net level of $39.51. SOL has remained at this level for weeks, still unable to rally to a higher valuation. This, however, has not prevented new users from joining in, even getting a benefit from the lowered price.
Solana wallets remain reliable, as are most crypto asset wallets that are made not to reveal private keys. The current exploit, however, uses the interaction where wallets have pre-approval to unlock their contents for the purposes of interacting with a smart contract. The best approach is to use more than one wallet and move most assets into cold storage in a new wallet or a hardware device.
