Developers can now easily test integrations with ICP and ICRC-1 ledgers directly on mainnet — no need to deploy your own test ledgers or use real tokens!
Why this matters
-
You can experiment with ICP and ICRC-1 ledger integrations out of the box — perfect for app development, wallet integrations, and transaction testing.
-
App developers can now let their users try out applications without needing real tokens or maintaining their own faucets.
-
Tokens are available for free through the new faucet:
