Paste-in tester that highlights suspicious spans and explains each flag.

Paste anything an agent might read. Moat highlights each suspicious span, names the rule that fired and explains in a sentence why it matters for an agent holding a wallet.

Planned

Try a token name

Detectors for instruction phrases, invisible Unicode, address look-alikes and encoded payloads.

Four detectors cover the inputs that reach trading, portfolio and support agents: token metadata, memos, direct messages and public feeds.

Every flagged input is stored with its agent, source, rule and verdict. On Monday morning a short summary lands in your Telegram chat.

Planned

Weekly summary, Monday 08:00

Questions.

Short answers. The docs have the rest.

What is Moat?

An injection filter for onchain AI agents: it scans the text an agent reads, such as token names, memos and messages, for hidden. It is tuned for crypto-native inputs like token metadata, memos and address substitution, not for generic chatbot safety.

What works today?

Moat is in development. Every feature is on the status list with what ships next, and the app opens in a sample workspace so you can see how it will work.

Do I need a wallet?

No. You can explore without one. Connecting a Solana wallet only shares your public address so Moat can read your balances; it never asks you to sign a transaction.

Who is it for?

Developers of trading, portfolio and support agents on Solana, and teams whose agents read public feeds.
