EIP-3091: Block Explorer API Routes

[pedrouid]

Providing wallet with a blockExporerUrl could be valuable given that applications can permissionessly interface with each other given that standards are followed and become interoperable.

Hence I've explored existing block explorers and identified existing patterns where these endpoints are in consensus and could be specified under a standard which this EIP describes

L1 Blockchain Explorers

Blocks

Blockscout (chainId=100) -> https://blockscout.com/poa/xdai/blocks/<BLOCK_HASH_OR_HEIGHT>
Etherscan (chainId=1) -> https://etherscan.io/block/<BLOCK_HASH_OR_HEIGHT>
Etherchain (chainId=1) -> https://etherchain.org/block/<BLOCK_HASH_OR_HEIGHT>
Ethplorer (chainId=1) -> unsupported

Etherscan and Etherchain are in consensus for blocks endpoint but Blockscout uses /blocks endpoint instead and Ethplorer doesn't have a page for blocks so returns 404 not found.

Transactions

Blockscout (chainId=100) -> https://blockscout.com/poa/xdai/tx/<TX_HASH>
Etherscan (chainId=1) -> https://etherscan.io/tx/<TX_HASH>
Etherchain (chainId=1) -> https://etherchain.org/tx/<TX_HASH>
Ethplorer (chainId=1) -> https://ethplorer.io/tx/<TX_HASH>

All block explorers are in consensus for transactions endpoint.

Accounts

Blockscout (chainId=100) -> https://blockscout.com/poa/xdai/address/<ACCOUNT_ADDRESS>
Etherscan (chainId=1) -> https://etherscan.io/address/<ACCOUNT_ADDRESS>
Etherchain (chainId=1) -> https://etherchain.org/account/<ACCOUNT_ADDRESS>
Ethplorer (chainId=1) -> https://ethplorer.io/address/<ACCOUNT_ADDRESS>

All block explorers are in consensus for accounts endpoint except Etherchain which uses /account endpoint instead

ERC-20 Tokens

Blockscout (chainId=100) -> https://blockscout.com/poa/xdai/tokens/<TOKEN_ADDRESS>
Etherscan (chainId=1) -> https://etherscan.io/token/<TOKEN_ADDRESS>
Etherchain (chainId=1) -> https://etherchain.org/token/<TOKEN_ADDRESS>
Ethplorer (chainId=1) -> https://ethplorer.io/address/<TOKEN_ADDRESS>

Etherscan and Etherchain are in consensus but Blockscout uses /tokens endpoint instead and Ethplorer doesn't have a page for tokens so redirects to accounts page (/address).

L2 Explorers

Blocks

Matic -> https://explorer.matic.network/blocks/<BLOCK_HEIGHT_OR_HASH>
zkScan -> https://zkscan.io/blocks/<BLOCK_NUMBER>
Fuel -> https://rinkeby.fuel.sh/block/<BLOCK_NUMBER>

Transactions

Matic -> https://explorer.matic.network/tx/<TX_HASH>
zkScan -> https://zkscan.io/transactions/<TX_HASH>
Fuel -> https://rinkeby.fuel.sh/tx/<TX_HASH>

Accounts

Matic -> https://explorer.matic.network/address/<ACCOUNT_ADDRESS>
zkScan -> https://zkscan.io/accounts/<ACCOUNT_ADDRESS>
Fuel -> https://rinkeby.fuel.sh/address/<ACCOUNT_ADDRESS>

ERC-20 Tokens

Matic -> https://explorer.matic.network/tokens/<TOKEN_ADDRESS>
zkScan -> unsupported (/tokens displays a list of tokens pointing to L1 explorer)
Fuel -> unsupported

EIP-3091

Thanks for the review @MicahZoltu 👍 updated PR

Thanks Guys i dont k ke what i was thinking. Nice work.

A couple minor things to get the bot to let this through, but otherwise looks good as a Draft EIP to me!
