Simple Summary

Standard API Routes for Blockchain explorers


This proposal brings standardization between block explorers API routes when linking transactions, blocks, accounts and tokens.


Currently wallets will link transactions and accounts to block explorers web pages but as chain diversity and layer two solutions grow it becomes harder to maintain a consistent user experience. Adding new chains or layer two solutions becomes harder given these endpoints are inconsistent. Standardizing the API routes to these links improves interoperability between wallets and block explorers. This EIP makes RPC endpoints like EIP-2015 more feasible.


Block explorers will route their webpages accordingly for the following data:







ERC-20 Tokens


Backward Compatibility

This EIP was designed with existing API routes in mind to reduce disruption. Incompatible block explorers should include either 301 redirects to their existing API routes to match this EIP.
