Testnet wallet

A wallet built to be thrown away.

Create a NEAR testnet account, collect 100 test mUSDC from the MEND faucet and watch the balance update. This is test infrastructure: the keys, token and every transaction have no real value.

LIVE TESTNET is not selected

The demo starts in REPLAY / SIMULATION. Wallet creation and the faucet are disabled until you explicitly select LIVE TESTNET and the configured API passes a health check.

Open mode controls

Step 1 · account

Create or load a testnet wallet

The API creates a real .testnet account. The secret key is returned once, kept in this tab's memory and never written to browser storage.

Test value

No wallet in this tab

Create a fresh testnet account, or load an existing account ID to read its mUSDC balance and storage. Replay never creates a wallet.

Tip: keep the downloaded JSON key out of the repository and out of shared drives.

Step 2 · test funds

Get 100 test mUSDC

The faucet sends a fixed test amount to the loaded account. A transaction hash is shown only when the API returns one; the explorer link is built for testnet only.

100 mUSDC

One request per wallet within the API cooldown. Test tokens cannot be swapped, sold or withdrawn.

Create or load a wallet first, then request test mUSDC.

Rate-limit guidance

The testnet faucet is shared infrastructure. If the API returns 429, wait for the cooldown shown above before retrying. Do not open parallel requests. Test value only — no refunds, no value, no mainnet path.

REPLAY / SIMULATION. The live API did not return usable data, so frozen protocol fixtures are shown. This is a replay fallback, not live data.
