ping-pub/faucet

General Faucet for Cosmos SDK testnet.

You can choose either Faucet Service or Self-hosted options:

Faucet Service

Why Faucet Service?

• High Concurrency: Capable of handling high concurrent requests.
• Robot Prevention: Only browser users are allowed to claim.
• No Deployment Needed: Simply requires a REST endpoint and basic configuration.
• Explorer Integration: Native integration with the Ping Dashboard on testnet.ping.pub.
• Customized Claiming Rules: Limited by IP address and wallet address.

Prepare for Faucet Service

• Submit Chain Configuration: You can submit your chain configuration here.
• Fund the Faucet: Find the faucet address on your faucet page and send some tokens to it.

Self-hosted

• Multi-chain: Supports multiple blockchains.
• Cosmos: Supports simple Cosmos-based blockchains.
• Evmos: Supports Evmos-like blockchains.

Does not support high concurrency and robot prevention.

faucet's Issues

Error: Invalid string. Length must be a multiple of 4

Requesting tokens throws Invalid string. Length must be a multiple of 4 although the tokens do get sent to the recipient address.
This is because of some breaking changes in tendermint version as per: cosmos/cosmos-sdk#11997
Updating cosmjs/crypto, cosmjs/proto-signing, cosmjs/stargate dependencies version to ^0.31 solves the problem.

Trying to setup faucet for EVM based chain. All started, faucet balance checked correctly, but at token request I've get following error
