I don't think this is right at all. The attack first created 100,000 wETH ($320 million) on the Solana side, and then bridged 93,750 wETH ($250 million) to ETH on the Ethereum side [1]. So some of the added ETH backs the remaining 6250 "extra" wETH tokens on the Solana side, but almost all of it would have gone to replace the stolen 93,750 ETH, and that's a pure loss. Either way I don't think this would cause any inflation, since the wETH still corresponds 1:1 with locked ETH.

Who is holding the SOL from the created wETH by the hackers at the end?

creating wETH doesn't create any SOL, they are separate things.

In a normal setting when a user deposits his SOL to create the wETH, where does the SOL go at the end when the wETH is settled? Where does the SOL go when it's released from the wETH?

The wETH pairs X amount of SOL with an ETH. When it's settled, it releases both the SOL and the ETH to the corresponding parties. When the wETH is falsely created, it creates the SOL it wraps.

You don’t deposit any SOL to create wETH, you deposit ETH on the ethereum side. That’s what the name means, “wrapped ETH”

wETH wraps ETH, not SOL.

So where does the SOL go in a normal transaction?

SOL is the gas on Solana smart contracts. In a "normal" transaction on Solana, SOL goes towards paying the TX fee itself.

In the case of the Wormhole bridge, there are transactions on both the Ethereum mainnet side (paid for in Ethereum gwei) and the Solana network side (paid for in Solana gwei). The only lossy factor is in the bridging fees themself which are typically a "flat" fee.

This isn't correct. There's no Solana tokens in the equation at all, so I assume you mean wrapped ETH on Solana, and that all got sent through the bridge to Ethereum, so it doesn't exist anymore.

Which wallet does the Solana tokens go when they are released from the wETH tokens?

I think you've gotten confused. Jump did have to fork over $320m worth of tokens to fill the hole from the hack. There's no weird accounting trick here

Who is holding the SOL from the created wETH by the hackers at the end?

No SOL was created, the transfer was sent to a zero address.

txid please

> Jump Trading fixed the problem by depositing $320M ETH tokens

Do you have an etherscan link (ie txid) for this?

At the moment all we've got is a "funds are SAFU" tweet.

$320M is not chump change. I have trouble believing this ends any other way than (a) Wormhole goes kaput, (b) hacker gets doxed and gives back the loot. There might be a lot of fractional-reserve posturing before one of these occurs, of course.

Yes and no. I see your point on one hand. Hackers mint 120k wETH. Bridge guarantees 1 wETH = 1 ETH. Therefore, hacker transfers 120k ETH to their Ethereum account. They can then sell this for approximately $320 M not to Wormhole or Jump Trading, but to the market who will collectively pay $320 M hypothetically (of course, slippage is a thing).

But, on the other hand, since Jump restored 120k wETH (valued at $320 M), they kind of are “out” that money in the sense that they would not have spent that without the hack. They are now forced into an “investment” of 120k wETH. They may profit from their investment if the price of the asset rises, but they may also lose some of their investment if the price decreases. Likely, it won’t fall to 0 so they are not “out” $320 M in the sense that the hackers directly stole that, but they essentially forced to trade $320 M for 120k wETH.

I don’t see how the public is screwed here. There is no “inflation.” They essentially increased the backing assets of the bridge by 120k wETH at current ETH market price.

The public invested in SOL directly or indirectly got their SOL value diluted by $320M. The public here includes Jump.

Although everyone shoulders a loss, it does give one slightly more confidence in the decentralized half of the DeFi equation.

Compare this Wormhole example to what happened with the Ethereum DAO attack that was "reversed".

> It's just the general public got screwed by having $320M of Solana tokens inflated up on them.

The general public didn't get screwed here. Solana ETH is an IOU for ETH. Now it's backed by ETH. It's not like anyone got diluted or anything.

“The SOL token distribution is as follows: 16.23% went towards an initial seed sale, 12.92% of tokens were dedicated to a founding sale, 12.79% of SOL coins were distributed among team members and 10.46% of tokens were given to the Solana Foundation. The remaining tokens were already released for public and private sales or are still to be released to the market.”

So how were the seed Solana tokens backed by ETH based on the distribution? Weren’t they created out of the thin air?

That's SOL, not bridged/"wrapped"-ETH that happens to exist on Solana as an IOU for actual-ETH on Ethereum.

Isn't it Jump Trading that is out $320M? Didn't they put up the money to make sure the maliciously created Solana tokens were backed by [whatever they're supposed to be backed by]? Jump doesn't own the tokens now, do they?

Jump Trading still has the maliciously created Solana tokens at the end, valued at $320M. They might lose some by Solana inflation but it's not like they're really out of $320M.

so can you use this as a loophole to print inordinate amounts of solana? confused how they inflated the supply

They apparently just supplied the backing assets without receiving anything in exchange, presumably to preserve trust in the larger ecosystem/chain. Pretty interesting precedent!

Sure. Ever wonder how Tether work? Ha.

Or central banks, for that matter? They print new money, and use it to buy and hold financial assets (usually government bonds). New money was added to the system, other assets were taken out.

Yea, if the public trades in Solana. But they are out of $320M in ETH which is way more used then Solana.

Yeah, so they accidentally expanded the supply of Solana tokens by $320M. Whether it's a good thing or bad thing, no one is sure.

They didn't expand the supply of SOL, they "expanded" the supply of wormhole bridged ETH, or rather returned the liquidity ratio of bridged ETH to 1:1.

Bridged assets are really just an IOU issued by the bridge, all the assets remain in custody of the bridge on whatever network they came from (in this case, Ethereum mainnet). As long as you can take that "IOU 1 ETH" to the bridge and get back 1 mainnet ETH, everything runs smoothly. If you can't, the market will decide the value of those IOUs accordingly.
