SF does not encourage, induce or sanction the deployment, integration or use of any such applications (including the code comprising the Solana blockchain protocol) in violation of applicable laws or regulations and hereby prohibits any such deployment, integration or use. This includes use of any such applications by the reader (a) in violation of export control or sanctions laws of the United States or any other applicable jurisdiction, (b) if the reader is located in or ordinarily resident in a country or territory subject to comprehensive sanctions administered by the U.S. Office of Foreign Assets Control (OFAC), or (c) if the reader is or is working on behalf of a Specially Designated National (SDN) or a person subject to similar blocking or denied party prohibitions.

The reader should be aware that U.S. export control and sanctions laws prohibit U.S. persons (and other persons that are subject to such laws) from transacting with persons in certain countries and territories or that are on the SDN list. As a project based primarily on open-source software, it is possible that such sanctioned persons may nevertheless bypass prohibitions, obtain the code comprising the Solana blockchain protocol (or other project code or applications) and deploy, integrate, or otherwise use it. Accordingly, there is a risk to individuals that other persons using the Solana blockchain protocol may be sanctioned persons and that transactions with such persons would be a violation of U.S. export controls and sanctions law. This risk applies to individuals, organizations, and other ecosystem participants that deploy, integrate, or use the Solana blockchain protocol code directly (e.g., as a node operator), and individuals that transact on the Solana blockchain through light clients, third party interfaces, and/or wallet software.

explorer's Issues

Block queries not supported

Not showing signature confirmations

Blocked on solana-labs/solana#9138 being released

Problem

The explorer needs to know which slot a particular transaction was added to and how many confirmations that slot has.

Proposed Solution

Wait for RPC update to get necessary information

Display user friendly names for account owners

UX: Linkify addresses in transaction details

The link should go to the account page so that a user can see an account's balance and other details

Blockhash is ambiguous on transaction details page

On transaction details:
Because it comes immediately after the "Block" number, the "Blockhash" reads as though it is the blockhash for that block, even though it is actually the recent blockhash submitted with the transaction.

Change the label to be more clear. "Recent blockhash" or "Transaction recent blockhash" might be enough?

Add live transaction feed

UI uses innacurate network names

Mainnet Beta (mainnet-beta.solana.com)
Testnet (tds.solana.com)
Devnet (devnet.solana.com)

Display dummy data for blocktimes of transactions too old to query

Problem

Currently the blocktime field is omitted on transactions that are too old to be queried from the cluster due to solana-labs/solana#10089. This can lead to community confusion, both innocent and malicious

Suggested solution

Display "Before LAST_QUERYABLE_DATE" or similar when we can't give a more precise date

Retry transaction status fetch a few times if not confirmed

• Batch transaction queries
• Setup status poller

Circulating supply is not displayed

sum of all accounts that aren’t the community/foundation/grant wallets and aren’t stake accounts with lockups

Break.solana.com transaction details are ugly

This is a subset of #57 but one that we should fix first. A break transaction in the explorer should look great, to give users more confidence that break is actually doing something

Rewrite to https

Explorer does not remember user's cluster selection

Cluster selection should be sticky and not reset when a user refreshes the screen. Should store this in local storage

Sync chosen cluster with browser url

Problem

Clicking on the "Accounts" or "Transactions" tab clears the url params. It's important to keep the cluster or clusterUrl param so that if a user shares the current url, the explorer will connect to the correct cluster

Transaction erroneously shows Not Found

Most of the time when I click the "View on Explorer" link in Break for a Pending transaction, the explorer page shows the transaction is not found, even though it is found on refresh.
Sometimes the webpage seems to flash the correct transaction details, but then reverts to Not Found.
Sometimes this also happens when inputting the url manually. Url is in this format:
https://explorer.solana.com/tx/SQAaeoU5Ba9Ga38cpLTcTcqnUYjERsEJNyHgnjoXWMXgBbzfPSaA9ojfwfeBX71d853teDuQJ146scEfvqLiXgf?cluster=testnet

It doesn't seem to matter how many confirmations the transaction has, although it seems somewhat less frequent for finalized transactions.

Firefox, MacOS

After clicking "Try Again":

Show toast error message when url parsing fails

We need errors for:

• url contains invalid transaction signature
• url contains invalid account address

The transaction details for a non-transfer is ugly

STR:

1. Create a stake account, like solana create-stake-account ~/stake16WnfUdP4uYZTuBr3ezc6MxS4GUd74jK6tkdDC.json 0.1 (or perform other non-system transfer transaction)
2. Check the details in the explorer:
   

Display historical transactions for an address

We recently added these two RPC APIs to serve this purpose:

• getConfirmedSignaturesForAddres - https://docs.solana.com/apps/jsonrpc-api#getconfirmedsignaturesforaddress
• getConfirmedTransaction - https://docs.solana.com/apps/jsonrpc-api#getconfirmedtransaction

No top 20 list for total supply

Problem

Top 20 list is for the circulating supply. Some, such as CoinMarketCap, are more interested in a top 20 list of the total supply, where we can label those accounts as Team, Foundation, Private Investor, etc.

Proposed Solution

Default the top 20 list to total supply, and instead offer a filter for the circulating supply.

Display payer account in transaction details

transaction history doesn't have a url, just a popup

http://explorer.solana.com/accounts/GsZxWiAkUFoLpfUcYP1fL7cFEgPDxN9MfbgN4R1XmRJh

would be better if the account page also displayed the history, or if the history had its own uri

http://explorer.solana.com/accounts/GsZxWiAkUFoLpfUcYP1fL7cFEgPDxN9MfbgN4R1XmRJh?history or something that makes sense

Not able to query account transaction history

Problem

When looking up a particular account, the explorer should show a history of transactions that involve this account

Blocked on RPC functionality

Confusing title in Top 20 list

Problem

The title "Active accounts" is causing confusion. Particularly, those HODLing, but in the circulating supply are surprised to see themselves labeled "most active".

Proposed Solution

A title like, "largest accounts on the circulating supply".

Account balance queries not supported

Add Transaction detail page

Problem

Transaction details are not easily shareable if you input a signature in the UI

Proposed Change

1. Update the url when a tx is clicked: /tx/signature_hash
2. Keep list view on /transactions route
3. Show transaction detail on /tx/signature_hash (also applies to /transaction, /txn
4. Instead of showing tx details in a modal, show them in a full page

Transaction history for deleted accounts is not accessible

STR:

1. Transact with an account
2. Drain the account of all lamports

Now you can't see any of the account transactions in the explorer.

eg:

even though:

$ solana transaction-history 7bEc4uCz4mECXwynU5iR5Xr5A8tbWJ5Nyx7YWfvUmaZE

Explorer hits "Instruction type incorrect; not a SystemInstruction" on multi-sig txn

The following transaction splits a stake account, sets new stake and withdraw authorities, and performs a system transfer. All instructions went through on the network without issue, but when I try to view the transaction details on the explorer, I land at a blank page, which @mvines states is due to the explorer hitting: https://github.com/solana-labs/solana-web3.js/blob/57a37920d19ba6b629aed4aaf99d1b600dee1ceb/src/system-program.js#L181

Not able to query transactions older than a few minutes

Waiting on solana-labs/solana#8823

Changes

• Update web3 to >= v0.43.0
• Specify searchTransactionHistory config when querying getSignatureStatus

Test for browser support

Add top level search bar

Problem

The input textbox is really small on mobile because it's part of the transaction/account table. Searching is a very common operation and should be front and center

Proposed Design

• Pull the input textbox out and turn it into search bar

Inspiration: http://localhost:3000/profile-projects.html (DashKit)

Make transactions in an account transaction history clickable

I looked up an account and found a transaction,

but now I need to copy-n-paste that 5pWRMSRP2vBkWo238B557VujNqcGM4A122dHqvVCM77QeAx3e7b9DVhbZuFdq7fqEMK4MNFD5RQX8qpXAaTVFXgA into a different part of the explorer to view it. Ideally there'd be an inline button or link that takes me to the transaction details

Can't see that locked up stake accounts aren't part of circulating supply

Problem

When viewing an account, there's no indication that it is locked up and therefore not part of the circulating supply.

Proposed Solution

Add an indicator, perhaps in an "Account Details" dialog. Something that mimics the information currently available in the output of solana stake-account <ACCOUNT_ADDRESS>.

Explorer does not show overall status of the network

Proposed Solution

• Add an icon displaying the health of the network

Health could indicate consensus, root progress, ...

Truncate base64 data in tx details view

Display transaction recent blockhash in details

Nonce instructions aren't nicely displayed

Instruction #2 is a InitializeNonceAccount:

Instruction #1 is a AdvanceNonceAccount:

Save inputted transactions to local storage

Cache supply adjustment transactions in explorer codebase

Problem

Currently, explorer transaction data persists for ~30 days. We would like to persist transactions related to the recent supply adjustment.

Proposed Solution

Cache the following six transactions in explorer codebase for persistent retrieval.

UX: Add an easy copy to clipboard feature for all addresses and signatures in the UI

Wherever there's a transaction signature or account address it'd be nice to have a "copy to clipboard" feature so I don't need to manually highlight the text.

Add disclaimer about history limits

Problem

Users get really concerned when their past transactions are not queryable. This is due to our nodes only storing a few days of transaction history

Proposed Solution

Add a disclaimer when transactions are not found stating that this may be due to incomplete history

Empty account balance should show as 0 instead of "Error"

but

$ solana balance vines1vzrYbzLMRdu58ou5XTby4qAqVRLmqo36NKPTg

Polish mobile UI

UI doesn't use Solana branding

Problem

The explorer is using the default theme from DashKit and doesn't match Solana's brand

Account lookup: getSignatureStatuses can fail on "too many inputs"

STR:
I searched for a random validator identity on mainnet-beta: FopTvQaGp6K5FadWKZtsLJmrX7gnNGFS2fQ7rv5KHyE1
Account lookup failed.

Looks like getConfirmedSignaturesForAddress queried the max slots (10k) and passed all those signatures (~9500) into a getSignatureStatuses query, which failed on "too many inputs". getSignatureStatuses is capped at 256 inputs, so this request needs to be split into batches.
That said, do we need to load so many confirmed signatures at once? Wondering about lazy-loading. Would we need an rpc for the most recent confirmed signatures for address, limited by number of signatures instead of number of slots?

Manifest information is still using placeholders

Problem

Manifest information isn't Solana specific (logos, name, description)

Explorer missing an "Executable" account detail

Explorer doesn't show details for transfer instructions

Problem

Explorer does not show from and to addresses and amount transferred for system transfer instructions

Proposed Changes

• Query getConfirmedBlock RPC endpoint to get the transaction details for a rooted block
• Search for system instructions
• Decode system instruction type and filter for transfers
• Decode transfer instruction

Copy tooltips cutoff, not copying

There are lots of things in the Account and Transaction details screens that pop up a "Copy" tooltip on hover.

1. The copy-on-click doesn't actually seem to copy anything to clipboard; Firefox 76 and Chrome 81, macOS
2. The tooltip gets cutoff by some content frames:
   

Display block timestamp in tx details

Display fees for transactions
