Overview
Wormhole is a cross-chain messaging network: it lets blockchains send tokens and information to each other. It was created in 2020, originally to connect Solana and Ethereum, and was developed with strong support from the trading firm Jump Crypto. Today it connects more than 30 blockchains.
Its W token launched in April 2024 with a large airdrop.
How it works
Wormhole relies on a group of 19 well-known validators called Guardians. When something happens on one chain — for example, tokens are locked in a bridge — the Guardians watch it and sign a message confirming it. Once enough Guardians sign, the message can be used on another chain, for example to release matching tokens.
Products built on Wormhole include:
- Portal, a bridge for moving tokens between chains;
- Native Token Transfers (NTT), which lets projects make their token work on many chains without “wrapped” copies;
- tools for sending data and queries across chains.
Many projects use Wormhole to launch their tokens on several chains at once.
The 2022 hack
In February 2022, an attacker exploited a bug in Wormhole’s Solana contract and created 120,000 wrapped ETH out of thin air, worth about $320 million at the time. It was one of the largest hacks in crypto history. Jump Crypto replaced the stolen funds within a day, so users didn’t lose money, but the event showed how dangerous bridge bugs can be.
The W token
| W at a glance | |
|---|---|
| Maximum supply | 10 billion W |
| In circulation (Oct 2026) | about 6.7 billion |
| Price (21 Oct 2026) | about $0.014 |
| All-time high | about $1.66 (April 2024) |
| Market cap | about $90 million (#306) |
W is used for governance and staking. In September 2025, Wormhole announced W 2.0:
- a Wormhole Reserve that collects revenue from the network and its apps and holds it in W;
- a base staking yield of about 4%;
- smaller unlocks every two weeks instead of huge yearly cliffs.
These changes made W more attractive on paper, but some holders were disappointed there was no burn of tokens. Unlocks continue to add supply, and the price has fallen about 99% from its launch high.
Security and reliability
Since 2022, Wormhole has run extensive audits and one of the largest bug-bounty programs in crypto, and it has not suffered another major hack. Still:
- Bridges are prime targets. They hold large amounts of locked tokens, making them attractive to hackers across the industry.
- Guardian trust. Security depends on the 19 Guardians not being compromised or colluding.
Wormhole vs. the competition
| Wormhole | LayerZero | Chainlink CCIP | |
|---|---|---|---|
| Security model | 19 Guardians | Configurable verifiers | Chainlink oracle network |
| Token | W | ZRO | LINK |
| Major hack | Yes (2022, $320M) | No major core hack | No |
| Strength | Solana and multichain token launches | Huge number of apps | Banks and institutions |
Our verdict
Wormhole is a core piece of crypto’s plumbing: many tokens and apps rely on it to work across chains, and the W 2.0 changes finally tie the token to network revenue.
But the market is crowded, bridges carry real security risk, and W has lost almost all of its value since launch. W is a very high-risk investment: invest only what you can afford to lose.
