Faucet for EVM chains
I had a lot of problems with existing simple faucets (the ones that do not force you to use some centralized service like twitter) and had the urge to create one that does not suffer from these problems for a while. Then a tweet of pari in context of faucet problems for the kintsugi merge testnet gave the spark to finally code the faucet.
This faucet uses hCaptcha instead of reCaptcha to not feed the google.
You can deeplink to a cain with the url parameter chain
that contains a chain-id.
And you can pass an address with a url parameter address
that will then be pre-filled.
docker run -p 8080:8080 ghcr.io/komputing/fauceth:release
Either download the tar from the release then after untar run:
./bin/fauceth
you can also build the tar via:
./gradlew distTar
or directly run tha app from within the repo via:
./gradlew run
You can set properties of FaucETH via a file called fauceth.properties
, via environment variables or system properties.
You should set app.chains
with a comma separated list of chain-ids and also hcaptcha.secret
and hcaptcha.sitekey
so you are protected by hcaptcha from faucet drainage.
Optional properties you can set are app.title
, app.imageURL
, app.amount
, app.logging
, app.port
or app.ethkey
In app.title
you can use %CHAINNAME
, %CHAINTITLE
, %CHAINSHORTNAME
- this is especially useful if you support multiple chains.
If your chains use infura RPCs please also set infura.projectid
After you started the app you can see the address by accessing locahost:8080/admin
- this way you can initially fund it.
What would be real nice would be a web3 faucet - if anyone has ideas how to realize it please contact me. The problem I cannot overcome is how to validate a captcha without a backend.
Yea you could use a PoH blockchain like idena or a dapp like Proof of Humanity or brightId - but often you need the faucet to get started with crypto - so there is a hen and egg problem here.
