i use stargaze route to click union testnet 9

claim stargaze faucet 
testnet.ping.pub/stargaze/faucet

then i make transfer here to union testnet 9
app.union.build/transfer

while making transfers, make sure to put the right receipient/receiver address if you want to push txns

also, you must make sure the sender wallet has some gas in the native token on the network, or you won't be able to approve transaction

takes about 30 minutes on this route, but doesn't stop you from processing another

pretty sure @union_build devs are working on increasing the transaction speed over time
