A place for developers to talk about building on Farcaster.

If anyone is building a multichain app but doesn’t wanna have to deal with remembering which block explorer a particular tx hash is on, you can use txha.sh just throw in the hash at the end of the url and it will automatically check all the popular/big chains and redirect you.

would default to this forever if it supported testnets and let me preselect/whitelist explorers. I want all traffic to go to OSS explorers

It's real good and has a great API for stuff like user token balances.

As in not etherscan explorers? Which testnet would you be looking for?

Ethereum

Releasing ESPLR - a local ETH block explorer.

Big problem of ecosystem is reliance on 3rd party RPCs (infura, alchemy, quicknode). Also reliance on 3rd party explorers (etherscan). They track users: it makes system one big panopticon.

Local nodes can make the situation better!

PC with an archive node only costs $40/mo or $500 one-time. Esplr only needs RPC URL of an archive node. It can view transactions, account balances and token transfer history (unique feature). https://github.com/paulmillr/esplr

This looks like a potentially interesting stripped back explorer

I don’t have a preference for explorers I just use whatever is the default in Viem/chains.
