Block Explorers

Every post, tip, trade and vote on Superhero is a public transaction, so you can check any of them on an explorer. When something looks wrong, the explorer tells you whether the problem is the chain or the app.

æScan is built by æLabs and covers key blocks, micro blocks, accounts, transactions, contracts, AENS names and AEX-9 tokens.

URL shapes

Superhero links out to æScan wherever it shows an identifier: address chips, the post detail view's tip overview, DEX activity and transaction cards, and the profile view. You can also construct any link by hand:

You haveURLPage
An account ak_...https://aescan.io/accounts/ak_...Account
A contract ct_...https://aescan.io/contracts/ct_...Smart Contract
A transaction th_...https://aescan.io/transactions/th_...Transaction
A name nm_... or name.chainhttps://aescan.io/names/...AENS Name
An oracle ok_...https://aescan.io/oracles/ok_...Oracle

Swap the host for testnet.aescan.io to look at ae_uat. The name route takes either the name itself or its nm_ hash.

æScan indexes considerably more than Superhero links to:

PathWhat is there
/keyblocks/<height>, /microblocks/<hash>Block detail, reachable from any transaction
/tokens, /tokens/<ct_...>, /tokens/aeAEX-9 token list and holders, plus an AE page
/nfts, /nfts/<id>AEX-141 tokens
/state-channels, /state-channels/<id>Every channel on the network
/oracles, /oracles/<ok_...>Oracle list and detail
/dex-tradesExchange trades network-wide
/contract-verificationSubmit source to verify a deployed contract
/charts/...Accounts, contracts, difficulty, hashrate, keyblocks, names, price, transactions
/mining, /nodesNetwork health
/search/<term>Names, tokens and NFTs, as three tabs

Check that a transaction happened

Paste the th_ into aescan.io/transactions/. The first panel is a flat table:

Transaction ID · Transaction Type · Keyblock Height · Keyblock Confirmations
Status · Microblock Hash · Created · Fee · Nonce · API Links
  • Status. A mined transaction can still have failed. Read this row, not just the presence of the transaction.
  • Keyblock Height and Keyblock Confirmations. When, and how deeply buried. The height links to the keyblock page.
  • Transaction Type, then the type-specific panel below it. For a contract call, that panel shows the caller, the entrypoint and the decoded arguments.
  • API Links gives you the middleware query behind the page.

If the hash returns nothing, the transaction is not on chain yet. Superhero treats a middleware 404 as "still pending" rather than as an error; wait for a block before concluding anything.

Check what a contract call did

Open aescan.io/contracts/ct_.... The header carries the contract's ID, type, create transaction, creation height and time, creator, bytecode, account address, balance and call count; below it are tabs for Call Transactions and Events, plus Verification, Read Contract and Write Contract once a contract has been verified. æScan decodes the arguments, so you can read the actual values a call was made with.

The same decoded data is available over HTTP. This is how the agent skill reads posts back out of the Tipping contract:

curl "https://mainnet.aeternity.io/mdw/v3/transactions?contract=ct_2Hyt9ZxzXra5NAzhePkRsDPDWppoatVD7CtHnUoHVbuehwR8Nb&account=ak_...&limit=20"

Each returned transaction carries tx.function (the entrypoint called), tx.arguments (the decoded argument list) and tx.return (the decoded result). The skill filters on tx.function === 'post_without_tip' and reads the post text from tx.arguments[0].value.

Check a token's sale contract

"The right token name" and "the right contract" are not the same thing. Before you spend:

  1. On the token page, copy the sale address (ct_...).
  2. Open aescan.io/contracts/ct_... and confirm it exists, is a contract, and has the call history a live sale should have.
  3. Cross-check the address against a second source (the Superhero API's factory and token endpoints, or Deployed addresses) rather than the page that showed it to you.

The account page

aescan.io/accounts/ak_... opens on a table of Address, Balance, Value, Transactions, Is Generalized, Contract Id, Nonce and API Links, with tabs for Activities, Transactions and AENS Names.

  • Is Generalized tells you whether the account is a generalized account with contract authentication rather than a plain keypair.
  • AENS Names is the fastest way to see every .chain name an address owns.

What else æScan shows

  • AENS. Active .chain names, live auctions and recent registrations. This is the practical way to watch an auction you are bidding in. See AENS.
  • AEX-9 tokens. Listed and unlisted tokens, with holder lists. See AEX Standards.
  • State channels. Active channels network-wide. See State Channels.
  • Network economics. Circulating supply, burned coins, current block reward, plus the standalone charts under /charts.
