Keekr

Alternative way to browse transaction list of the account on NEAR protocol.

What exact problem does Keekr solve?

Default NEAR explorer is cool, but for people that are not familiar with the blockchain / NEAR technology it may be hard to understand what's going on. I'm talking about that bunch of "Called method" headings, like:

Called method: 'ft_transfer_call' in contract: token.v2.ref-finance.near
Called method: 'near_deposit' in contract: wrap.near
Called method: 'deposit_and_stake' in contract: aurora.pool.near

Keekr will show you this information in more human friendly way:

Send 1073.5427346276563 REF (Ref Finance Token) to v2.ref-finance.near
Wrap 1,000 NEAR using wrap.near contract
Deposit and stake 2,548 NEAR to the validator aurora.pool.near

Yes, it couldn't "humanize" each function call, but it still better than nothing.

What kind of function calls can Keekr recognize?

Most important infrastructure actions:

• wNEAR transfers to Aurora
• Stake / Unstake / Withdraw actions on validators
• Account creating via near contract
• NEAR wrap / unwrap actions
• Fungible tokens transfers / storage deposit
• Interactions with NFT contracts
• Some method calls of another familiar contracts (such as Ref.finance)

And off course it can handle other action types that are not related to function calls:

• CreateAccount
• DeployContract
• Transfer
• Stake
• AddKey
• DeleteKey
• DeleteAccount

Filter transaction list

Another fancy thing: Keekr allows you to filter transaction list. I.e. you can browse only transactions related for specific token or NFT contract.

Known issues

• Keekr uses super cool near-contract-parser to recognize possible interface of the contract. This procedure takes few seconds and may freeze browser's tab. Obvious solution is to move this execution on the server side and cache it.
• Batched transaction displays as separated transactions

Future plans

• Huge code refactoring (probably will use React)
• Deeper function call recognition for NFT contracts
• Support of the function call recognition for more popular contracts
• Server-side caching
• UI/UX improvements

Please, keep in mind that this is the first app that I've been developing by myself. I don't have much experience in building applications. So be prepared to face some strange (awful?) coding solutions inside.
