Before you send. We check the format, the likely chain, common dust-attack patterns, and vanity-prefix warning signs. We do not connect to any blockchain, we do not call any API, and we do not store anything. It runs in your browser.

What this checks
- · Address format and length per chain
- · Bech32 / Base58 checksum validation
- · Vanishing-prefix risk patterns (e.g. addresses ending in many zeros)
- · Chain inference from format alone
What this does not do
- · It does not look up on-chain history or balances
- · It does not contact any third party
- · It does not give a "safe / unsafe" verdict — only signals
- · It is not a substitute for your own due diligence
