How we label wallets

Where the names and chips beside an address come from, what each kind of label means, and what a label can never tell you.

The Blitzscan team4 min read

An answer about Robinhood Chain is mostly addresses. A list of holders or traders is hard to read if every row is 0x and forty characters. So Blitzscan puts a name and a kind beside an address when it has evidence for them.

This post explains where those labels come from, how they show in an answer, and what they do not prove.

What a label is

A label says what an address does: it is a DEX pool, a bridge, an exchange wallet, a token contract or a Safe. Some labels also say how an address behaves, for example that it trades often.

A label never says who is behind an address. One person can use many addresses. One address, such as a pool or an exchange, can hold tokens for many people. Labels are our best reading of public evidence. They do not prove who controls an address.

The kinds of label

Each labelled address gets one category:

CategoryWhat it means
ExchangeA wallet of a trading venue
BridgeA contract that moves tokens between chains
DEXA pool, a pool factory or a router that trades go through
ProtocolA contract of a known on-chain application, such as a lending market
TokenA token contract
DeployerAn address that created a large number of contracts
SafeA multi-signature wallet made from the Safe factory
Trader or botA pattern of behaviour, never a name

Where the names come from

No single source names enough of the chain, so Blitzscan combines several. From the most trusted to the least:

  1. Published deployments. Protocols publish the addresses of their own contracts, and Robinhood Chain documents its own system contracts and gateways. These names are taken as written.
  2. The chain itself. Every pool is named after its brand and its pair, for example "Uniswap v3 pool WETH/USDG". Pool factories, routers, Safes and token contracts are found from what they do on chain. A contract that at least 500 different senders call in swapping transactions over a day is a "DEX router". An address that created 100 or more contracts is a deployer.
  3. Data partners. Names that partners record for an address. When the only evidence is from another chain, the name says so, for example "(known on base)", and it counts for less.
  4. Our own research. We looked at the top 50 holders of the 100 tokens with the most DEX volume over 30 days, where no other source named the holder. Each one was labelled from its on-chain evidence: how it was created, who calls it, its events, its counterparties and its trades. A second reviewer then checked each label against the same evidence, and confirmed, changed or rejected it. A researched label never outranks a name from a published deployment.

When two sources disagree about one address, the more trusted one wins. The labels are rebuilt from all sources every day, so a new pool or a newly published contract gets its name without anyone typing it in.

Behaviour is not identity

Trader and bot chips describe what an address did, not what it is. The trader chip follows one rule for everyone: 100 or more DEX trades on 3 or more days. It never carries a name, and it does not say whether the trading made money.

How labels show in an answer

  • In the text, a known name comes first and the short address follows it: "Uniswap v4 Pool Manager (0x8366...0951)". The address links to the explorer, so you can check it.
  • In tables, an address shows its name, a copy button and its chips, such as DEX, EXCHANGE, BRIDGE, SAFE or TRADER.
  • On cards, a wallet or token answer starts with a card. The card shows what kind of entity it is, with its chips beside the name.
  • In charts, the share-of-supply donut hatches contracts such as pools, vaults and bridges, because they hold tokens for other people.
  • In rankings, labels decide what to leave out. Wallet rankings leave out system addresses, such as the zero address used for mints and burns. Profit rankings also leave out bridges and solvers, whose balances turn over with every fill. A footnote says so when it applies. Ask for "individual traders, not protocols or exchanges" and the answer leaves those out too.

Tokens get labels too

Many tokens on Robinhood Chain share a symbol, so a token's name alone does not say which contract it is. Each symbol has at most one recognised contract. Fixed rules choose it from public evidence, such as Robinhood's own list of its stock tokens, and never from trading activity alone. Other contracts with that symbol carry a LOOK-ALIKE chip, which names the recognised one. Where several busy contracts share a symbol and none is recognised, each carries SHARED SYMBOL. Only recognised tokens show a logo.

When a label looks wrong

Open the address on the explorer from the answer and look at what it did. If the label still looks wrong, press thumbs down under the answer and choose "Wrong data". The team reads these reports.
