Blockchain Tools command and transaction guide

Read-only commands

Blockchain Core and a compatible provider supply the active ecosystem and chain. Common Tools commands include gas, rpc test, address ADDRESS, tx HASH, block latest, token TOKEN, token balance TOKEN [WALLET], allowance, approvals, ens, logs, contract, nft, program, risk, activity, and history. Run help COMMAND for the current syntax, access level, supported networks, and examples.

Read operations never authorize a transaction. Verify addresses and chain context independently before treating a result as financial evidence.

Preview and guarded sending

Pro write tools are disabled by default. Enable Guarded sending tools only after testnet certification. A send begins with a normalized intent and facts-only simulation. The interface shows exact chain, action, destination, amount/method, risk, and warnings. The visitor must confirm the immutable preview before a provider prompt can open. Any relevant change invalidates confirmation.

Use preview native …, preview token transfer …, or an approved trusted-contract integration before send. High-risk actions may require an exact typed phrase. Trusted contract writes additionally require Core 0.17+, an exact write allowlist entry, typed callable schema, Pro access, a compatible EVM provider, and zero native value in this release.

After submission, keep the page open for receipt monitoring. A mined EVM receipt needs two stable block confirmations. Closing the page stops page-local monitoring; cross-session browser-assisted resumption requires the optional Core journal and user consent.

Journal operations

Use journal status, journal consent ENABLE, journal list, journal inspect INDEX, journal inspect pending [LIMIT], journal retry, journal clear CLEAR, and journal revoke REVOKE. Inspection never switches networks automatically and skips entries for another context.

Troubleshooting

• Command unsupported: check current ecosystem, network, provider capability, and Free/Pro boundary.
• Preview expires: create a fresh preview; unconfirmed previews expire after 90 seconds.
• Simulation or chain check times out: do not bypass it; verify provider/network health and retry.
• Send blocked: confirm guarded tools, capability, wallet account, exact network, simulation, and confirmation.
• Receipt stays pending: keep the page open or reconnect to the exact saved chain and inspect the journal entry.

Never paste seed phrases, private keys, API secrets, or unsigned raw calldata into a terminal command.
