Solana Devnet · Phantom

Intelligenttransactions.Verified intent.

A Solana-native workspace for wallet activity, transaction review, and evidence-driven security intelligence.

Launch app

Solana transaction lifecycle

One transfer, five handoffs, nothing hidden.

Each step says who is acting. QEVRA reviews and reports; Phantom signs; Devnet decides whether it happened.

  1. You

    Draft

    Enter a recipient and an amount in SOL. Amounts are exact lamports, with up to nine decimal places.

  2. QEVRA

    Review

    QEVRA checks the cluster, your balance, the fee and the blockhash, then shows the whole transfer with a fingerprint of the exact message. Change anything and the review is discarded.

  3. Phantom

    Approve

    Phantom is asked to sign the same message. Decline, and nothing is sent.

  4. QEVRA

    Submit

    The signed message is compared with the review and simulated on Devnet, then submitted once. Its signature is tracked from that moment.

  5. Devnet RPC

    Confirm

    Confirmed, failed, expired or still unknown: the app reports whichever one RPC returns, and links the signature to the explorer.

Transaction Intent Review

Know exactly what you are about to sign.

Before Phantom opens, QEVRA writes the transfer out in plain terms. You see who pays, who receives, how much leaves your wallet and on which network.

  • Every field, in full. Addresses are never shortened in the review.
  • Fee included. The estimated network fee and the total debit sit next to the amount.
  • One message. The fingerprint identifies the exact message Phantom is asked to sign.

Security Swarm

Evidence-driven research, behind your wallet.

Security Swarm turns a question into a source-backed finding. Research gathers approved sources, Analysis interprets them, Verification checks the claims, and you review the result. It is owner-only with wallet sign-in, and the Security workspace shows exactly what is configured. Nothing it produces is an audit.

Open the Security workspace

  1. Stage 01

    Research

    Collect the sources and context behind a contract, address or transaction.

  2. Stage 02

    Analysis

    Reason over that evidence and propose findings, each tied to what supports it.

  3. Stage 03

    Verification

    Keep only what can be reproduced. Everything else is marked as unverified.

Evidence-driven research

A finding without evidence is not a finding.

  • SourceWhere the information came from.
  • MethodHow the conclusion was reached.
  • ReproductionHow anyone can check it again.
  • StatusVerified, or honestly unverified.

Product transparency

A clear boundary for every capability.

Works today

  • Phantom discovery and connection through Wallet Standard
  • Devnet identity check by genesis hash before any read
  • SOL balance in exact lamports
  • SPL Token and Token-2022 account discovery, and the mint inspector
  • Recent address activity decoded from RPC
  • Network monitor: health, identity and slot

Built, awaiting live verification

  • Reviewed native SOL transfers: the flow is implemented and unit-tested, but a live Phantom signing run has not been completed end to end
  • Security Swarm: wallet sign-in, research queue, worker, database and owner review are implemented and tested, but they need private configuration, and provider-backed research and Human Review have not been verified live

Not built

  • Token swaps and any price or quote data
  • Token transfers
  • Mainnet; QEVRA is pinned to Devnet
  • Verified, live Security Swarm research output
  • Token names and symbols from a trusted metadata source

Open the workspace.

Connect Phantom on Solana Devnet, read your wallet, and review a transfer before you sign it.
