Tools
Utilities under core.app/tools that developers end up using more than anyone else.
Testnet faucet
Funds accounts on test networks — Fuji AVAX for the C/X/P-Chains among them — so integration work never depends on real funds. Pair it with testnet mode and the whole surface of these docs is exercisable end to end.
Signing tools
Inspect and produce signatures outside a dapp flow: useful when debugging
what a personal_sign or typed-data payload
actually hashes to, or verifying a signature a contract rejected.
Transaction export
Exports an account's transaction history — the same data as the activity view — as a file suitable for accounting and analysis.
Revoke access
Lists the ERC-20 allowances an account has granted and lets the user revoke
them. Every allowance your dapp requests via approve shows up here with
your spender address attached — a reason to request bounded allowances
rather than type(uint256).max: users reviewing this list are deciding
whether to keep trusting your contract.
