Guardian Multichain Scan

Paste-first token scanner for Solana, Ethereum, Base, Arbitrum, Robinhood Chain, and XRPL.

Guardian reports grades and patterns, not verdicts. A high grade is not an endorsement. A low grade is not a finding of fraud.

How it works

Paste an address. There is no chain dropdown first — that is a brand promise.

• Base58 (32–44 chars) → SolanaAdapter
• 0x + 40 hex → EvmAdapter, which probes every configured EVM chain and scans where bytecode exists
• Classic r… (checksummed, 25–35 chars) → XRPLAdapter. Longer r… strings that fail the XRPL checksum can still be Solana.

The chain row under the paste box is a billboard. Tapping a chain shows example chips and an address-format hint. It never filters or gates the paste box.

XRPL issued tokens are a currency + issuer pair. Paste an issuer: multiple currencies → pick one; one currency → report immediately; nothing issued → account report (blackhole, freeze flags). XRPL is not EVM — signals are protocol-level flags from public nodes (https://xrplcluster.com, no API keys). Honeypot simulation is omitted.
