I did some research on how to get transaction history of NUM token by address

• Numbers wallets API list all crypto-transactions ( https://api.numbersprotocol.io/api/v3/redoc/#operation/wallets_crypto-transactions_list )

  • It doesn’t seem to work??? I didn’t get any transaction
  • Is pk_pk the public key?

• EtherScan/BscScan

  • https://docs.etherscan.io/api-endpoints/accounts#get-a-list-of-erc20-token-transfer-events-by-address ( https://docs.etherscan.io/api-endpoints/accounts#get-a-list-of-erc20-token-transfer-events-by-address )
  • https://docs.bscscan.com/api-endpoints/accounts#get-a-list-of-bep-20-token-transfer-events-by-address ( https://docs.bscscan.com/api-endpoints/accounts#get-a-list-of-bep-20-token-transfer-events-by-address )
  • Cons: max 30 calls/second even if we have a professional account. Also we need one subscription for etherscan and another for bscscan

• Tatum

  • https://tatum.io/apidoc.php#operation/Erc20GetTransactionByAddress ( https://tatum.io/apidoc.php#operation/Erc20GetTransactionByAddress )

    • There’s a chain parameter. Can we use this to get bep20 transactions?

  • Not sure if it supports getting bep20 transactions by address

  • No rate limit for enterprise plan

• Ethplorer API

  • https://github.com/EverexIO/Ethplorer/wiki/Ethplorer-API#get-address-info ( https://github.com/EverexIO/Ethplorer/wiki/Ethplorer-API#get-address-info )
  • Limit 10 req/sec

• Or maybe try https://bitquery.io ( https://bitquery.io )?

  • No rate limit starting with growth plan

• Using web3.js ( https://stackoverflow.com/questions/48924905/how-to-get-token-transaction-list-by-address-using-web3-js )?

In terms of work around, I already have a prototype for launching an browser to bscscan. But not sure how to make the browser launch within the app (like launching CaptureClub)

Update: Based on what we discussed during the demo today, we'll go with the simple workaround and just use hyperlink point to etherscan/bscscan. We'll prioritize enabling user to see network application order history perhaps in the next sprint.

Create a task for Show network application order history ( https://app.asana.com/0/1201016280880500/1201834966185809/f )

Echo the future plan, here is the priority I suggested:

1. Workaround for showing transactions
2. Implement network-action order history (spring 0303)
3. Implement custody-wallet transaction history (can schedule this in April)

I think whether we could show custody-wallet transaction history in app depends on whether we can find an api to retrieve "transaction history of NUM token by address". Some 3rd party api I'm aware of:

• EtherScan/BscScan

  • https://docs.etherscan.io/api-endpoints/accounts#get-a-list-of-erc20-token-transfer-events-by-address ( https://docs.etherscan.io/api-endpoints/accounts#get-a-list-of-erc20-token-transfer-events-by-address )
  • https://docs.bscscan.com/api-endpoints/accounts#get-a-list-of-bep-20-token-transfer-events-by-address ( https://docs.bscscan.com/api-endpoints/accounts#get-a-list-of-bep-20-token-transfer-events-by-address )
  • Cons: max 30 calls/second even if we have a professional account. Also we need one subscription ($399/month) for using etherscan and another one for using bscscan

• Tatum

  • https://tatum.io/apidoc.php#operation/Erc20GetTransactionByAddress ( https://tatum.io/apidoc.php#operation/Erc20GetTransactionByAddress )

    • There’s a chain parameter. Can we use this to get bep20 transactions?

  • $49/month for 200 req/sec

  • Not sure if it supports getting bep20 transactions by address

  • No rate limit for enterprise plan

Close this task since the workaround PR has been merged. Create a new task View custody-wallet transaction history within Capture app ( https://app.asana.com/0/1201016280880500/1201854254172802/f ) to track the non-workaround implementation
