How secure is Wormhole?

Wormhole is a cross-chain bridge service that allows you to transfer tokens and NFTs between different blockchains, such as Ethereum, Solana, Terra, and Binance Smart Chain. Wormhole claims to have one of the best security programs in all of web3, with several features that make it secure, fast, and compatible. Some of these features are:

  • Wormhole is trustless and decentralized. It does not rely on any central entity or federation to run the bridge. Instead, it uses a network of 19 validators that run the Wormhole Core Layer, which is a protocol that verifies and relays cross-chain messages. The validators use a consensus algorithm called Proof of Authority (PoA) to agree on the state of the bridge and the validity of the transfers.

  • Wormhole is fast and cheap. It can transfer tokens and NFTs between chains in a matter of seconds, with minimal fees. This is because Wormhole uses a smart contract on each chain that acts as a gateway for the tokens and NFTs. The smart contract issues wrapped tokens or NFTs that represent the original assets on the other chain.

  • Wormhole is compatible and flexible. It supports any ERC-20 token, ERC-721 NFT, SPL token, CW20 token, and BEP-20 token. It also supports metadata and royalty information for NFTs. You can use Wormhole through various interfaces, such as Portal, Sollet, or Terra Station. You can also use it programmatically through the Wormhole SDK.

Wormhole also has a rigorous auditing process, where it performs internal audits and hires external audit firms to review its code and contracts. It has published several audit reports on its website¹. Additionally, Wormhole has a bug bounty program that rewards white-hat hackers for finding and reporting vulnerabilities in the protocol. The bug bounty program has a record-breaking $10 million USDC reward pool and has paid out more than Google did for Chrome and Android in 2021.

Based on these information, it seems that Wormhole is very secure and reliable. However, as with any crypto project, there are always risks involved when using it. You should always do your own research and due diligence before transferring your tokens or NFTs across chains. You should also be aware of the terms and conditions of using Wormhole, such as the fees, the risks of losing your assets, and the legal implications of cross-chain transfers.
