LayerZero vs Wormhole: how the two messaging networks differ
LayerZero and Wormhole are not bridges you use directly. They carry messages between chains, and apps like Stargate, USDT0, Portal and Mayan are built on top of them. The main difference is who checks those messages.
What they actually are
Both are cross-chain messaging protocols. A message says, for example, that tokens were locked on one chain so they can be released or minted on another. Users rarely touch them directly: they use an app built on top.
Apps on LayerZero include Stargate and USDT0. Apps on Wormhole include Portal, Mayan and many Native Token Transfers deployments.
Who verifies messages
Wormhole uses a fixed set of 19 Guardians, well-known validator companies. A message is valid when at least 13 of them sign it. The same set protects every app on Wormhole.
LayerZero lets each app choose its own verifiers, called DVNs (decentralized verifier networks), and how many must agree. Security therefore depends on the settings of the specific app, not on LayerZero as a whole.
Token standards
LayerZero's OFT standard lets a token exist natively on many chains: it is burned on one chain and minted on the other, without a wrapped copy. USDT0 is a well-known example.
Wormhole's NTT framework (Native Token Transfers) does the same job for tokens that choose it. Wormhole's older Token Bridge, used by Portal, instead creates wrapped tokens on the destination chain.
Chain coverage
Both connect the major EVM networks and many others. Wormhole has long been strong on Solana, Sui and Aptos. LayerZero covers a very wide list of EVM networks and also supports Solana and other non-EVM chains. Always check the specific app, because an app may not use every chain its protocol supports.
Security history
In February 2022 an attacker exploited a bug in Wormhole's Solana contract and minted about 120,000 wrapped ETH. Jump Crypto replaced the funds, so users were made whole. LayerZero has had no comparable core exploit, but individual apps can still be misconfigured, for example by relying on a single verifier.
What this means for you
Compare the app, not just the protocol underneath:
- Check whether you receive a native token (OFT, NTT, CCTP) or a wrapped copy.
- Prefer apps that are well known and audited, and whose token issuer supports them.
- For Solana transfers, Wormhole-based apps such as Mayan are common; for stablecoins across EVM networks, LayerZero-based Stargate and USDT0 are common.
- Compare the amount you receive across several apps before sending.

Best bridge to Solana: how to choose
There is no single best bridge to Solana. The right choice depends on what you send and where it starts. Solana uses a different wallet and address format, so you need a Solana wallet such as Phantom, Solflare or Backpack before you start.

Both swap native assets such as BTC, ETH and SOL across chains without wrapped tokens and without an account. THORChain has the longer track record and more chains, Chainflip often gives tighter prices on BTC, ETH and SOL thanks to its just-in-time liquidity. Compare quotes on the day.

Both let you swap crypto across networks without an account: you send to a deposit address and receive the other coin. ChangeNOW supports more coins and networks, SideShift is known for a clean interface and clear quotes. Both hold your funds during the swap and may ask for checks on flagged transfers.
