Messages
Messages and token value by route and product.
Token value moved
USDToken value carried by Token Bridge and NTT transfers in the period, valued at the publish block.
Guardians in the current set
countKeys in the guardian set currently stored in the core contracts, shown with the set's index.
Median delivery time
minutesThe median time from a transfer's publish block to its redemption block in the period.
Messages by day and source chain
countMessages published each day, split by the emitting chain.
Busiest routes
Each route's messages, token value, product mix and median delivery time over the period.
Tokens
Wrapped supply, NTT tokens and their rate limits.
Wrapped tokens outstanding
USDSupply of Token Bridge wrapped assets on covered chains at the latest day's end, valued at oracle prices.
NTT tokens tracked
countTokens deployed with Native Token Transfers on covered chains.
Value by product

About
What it answers, and for whom.
Wormhole is a messaging protocol watched by nineteen guardians. A contract on one chain publishes a message through the Wormhole core contract; once at least thirteen guardians have signed it, the signed message, called a VAA, can be submitted on any other chain Wormhole supports, where it is checked against the current guardian set. Token transfers ride on these messages.
Two products carry most of the token value. The Token Bridge locks a token on its home chain and mints a wrapped copy elsewhere. Native Token Transfers, or NTT, let a token's issuer move it in its own form, by burning and minting or by locking and minting, with rate limits the issuer sets. This dashboard counts both from the contracts, with every message keyed the way the guardians sign it.
The 2022 exploit, in which a flaw in the Solana contracts let an attacker mint wrapped ETH that nothing backed, is why the dashboard also tracks wrapped supply beside what is locked.
Method
How it will be measured.
Every figure will be read at a block, kept with its source and its exact read, and open a receipt anyone can re-check.
How receipts work →- Messages are LogMessagePublished events from the Wormhole core contract on each chain, keyed by emitter chain, emitter address and sequence, the same key the guardians sign, so each message counts once.
- Deliveries are the destination transactions that verify a message's VAA, such as a Token Bridge redemption or an NTT receive, and the delivery time is the gap between the two blocks.
- Token value comes from decoded Token Bridge and NTT transfer payloads, valued at oracle prices at the publish block; wrapped tokens outstanding are each wrapped asset's totalSupply at the day's last block.
- NTT rate limits are read from each NTT Manager's inbound and outbound limits at the latest block, and the guardian set in force is read from the core contract.

Questions
Questions people ask.
How does Wormhole work?
A contract publishes a message through the core contract on its chain. Wormhole's nineteen guardians observe it, and once at least thirteen have signed, the signed message can be delivered to any chain Wormhole supports, where the core contract there verifies the signatures before the receiving app acts.
Who are the Wormhole guardians?
Nineteen validator operators that each run nodes for the chains Wormhole connects and sign the messages they observe. A message needs a supermajority of their signatures, and the set can be changed only through a message the guardians themselves sign.
What is the difference between the Wormhole Token Bridge and NTT?
The Token Bridge locks a token on its home chain and mints a wrapped copy, controlled by the bridge, on other chains. NTT lets the issuer deploy its own token on each chain and move it by burning and minting or by locking and minting, with its own rate limits and settings.
What is the Wormhole Governor?
A safety feature in the guardians' software that limits how much value can leave each chain in a day through the Token Bridge and delays very large transfers. It caps what a single flaw could take before people notice.
Was Wormhole hacked?
Yes. In February 2022 an attacker bypassed signature verification in Wormhole's Solana contracts and minted wrapped ETH with no ETH locked behind it. Jump Crypto replaced the missing ETH and the flaw was fixed. The bridge hacks table ranks this incident among the others.
- VAA
- A verified action approval: a Wormhole message carrying the guardians' signatures, which any chain's core contract can check.
- Guardian set
- The list of guardian keys whose signatures are valid at a given time, stored in the core contract on each chain.
- NTT
- Native Token Transfers, Wormhole's framework for moving an issuer's own token between chains without a wrapped copy.
