Paste any Solana SPL token mint address and see its on-chain facts in seconds — total supply, mint authority status, freeze authority status, and decimal precision. No wallet connection. No fees. No sign-up.
Default is the TrustTails (TAIL) mint. Paste any Solana SPL mint address to check it.
The checker reads the raw 82-byte SPL mint account directly from the Solana blockchain. Here is what each field tells you about a token's trustworthiness.
The human-readable total number of tokens that exist on-chain. This is calculated from the raw 64-bit integer stored in the mint account, divided by 10 raised to the power of the token's decimals. A fixed supply that matches the project's stated figure is a positive transparency signal. Any discrepancy between the on-chain supply and a project's claims deserves scrutiny.
This determines whether new tokens can be created. When the mint authority is Revoked, no one — not the team, not the deployer, not anyone — can ever mint additional tokens. The supply is mathematically fixed. When it is Active, the controlling wallet can inflate the supply at any time, diluting all holders. Revoked is the gold standard for supply integrity.
This determines whether individual token accounts (wallets holding the token) can be frozen, preventing transfers. When Revoked, no one can freeze your tokens — your ability to transfer is fully sovereign. When Active, a central party can lock anyone's balance. Many stablecoins intentionally keep this for compliance. For community tokens, revoked is the expected state.
The number of decimal places the token supports. Most fungible Solana tokens use 6 or 9 decimals. This value is used to convert the raw integer supply stored on-chain into the human-readable figure you see. It is set at token creation and cannot be changed. For reference, SOL itself uses 9 decimals (lamports).
When a Solana token's mint authority and freeze authority are revoked, specific promises become mathematically enforceable on-chain — no trust in the team required.
Context matters. Active authorities are not automatically fraudulent — many legitimate stablecoins and institutional tokens keep them for regulatory or operational reasons. The checker's job is to surface facts so you can make informed decisions. Always read a project's documentation and understand why a given state exists before drawing conclusions. This is not financial advice.
No magic, no middlemen. The tool reads the raw account data directly from a public Solana RPC node and decodes the 82-byte SPL mint layout.
Your browser sends a getAccountInfo request to a public Solana RPC endpoint (no API key required). The request asks for the account data at the mint address you provided, encoded as base64.
The RPC returns a base64-encoded string. This is decoded into an 82-byte Uint8Array — the exact binary layout of an SPL Mint account as defined in the Solana Program Library source code.
The 82-byte buffer is parsed at known offsets using the SPL Token mint layout:
mintAuthorityOption (uint32 LE — 0 means revoked)supply (uint64 LE — raw token units)decimals (uint8)isInitialized (bool)freezeAuthorityOption (uint32 LE — 0 means revoked)Supply is divided by 10 ** decimals and formatted with locale-aware commas. Authorities are shown as Revoked or Active based on the option flag. A direct Solscan link is generated so you can cross-verify independently.
The tool tries solana-rpc.publicnode.com first, then falls back to api.mainnet-beta.solana.com if the first request fails. Both are public endpoints requiring no authentication. Rate limits apply — if you see errors, wait a moment and try again.
These are the verifiable on-chain facts for the TrustTails token. Run the checker above with the TAIL mint to confirm them yourself — no claims, only code.

TrustTails is a pre-launch community token. These on-chain facts are verifiable by anyone. They are not a guarantee of future value, adoption, or returns. Cryptocurrency is high-risk. Only interact with what you can afford to lose entirely.
The on-chain checker helps you verify a token's technical facts. But understanding common scam patterns is equally important before interacting with any project.
No legitimate crypto project will DM you with "exclusive presale" access. Be extremely sceptical of any unsolicited messages offering early token access, whitelist spots, or "insider" prices. Verify all official links only through the project's public social profiles and website.
Many scam tokens use similar names, tickers, or logos to impersonate real projects. Always verify the exact mint address against the official contract published on the project's official website. A matching name and logo is not enough — only the mint address is authoritative.
Never connect your wallet to an unfamiliar site because someone told you to. Wallet connection prompts that request broad permissions ("Approve all transactions") are a major red flag. This checker requires no wallet connection whatsoever — always prefer tools that work without one where possible.
Scam projects frequently claim to be "audited," "KYC verified," or partnered with major companies without evidence. Always ask for verifiable proof — published audit reports with a reputable firm's name, not just a badge on a website. Check if the audit firm can confirm the report exists.
Promises of guaranteed returns, fixed APY percentages, or "100x" price projections are hallmarks of high-risk or outright fraudulent schemes. No one can guarantee cryptocurrency returns. Be especially sceptical of projects that lean on price predictions as their primary selling point.
Pressure phrases like "only 2 hours left," "last chance," or "buy before it lists" are designed to prevent you from doing due diligence. Legitimate projects give you time to research. If you feel rushed, that is a signal to slow down, not speed up.
