You can paste a full Cardano address or an ADA handle (e.g. $mato).
How it works
① You write a short message (up to 256 characters).
② Your wallet signs a transaction that mints a tiny NFT containing your message as text plus a small on-chain SVG bubble image.
③ Optionally, the message text can be encrypted on-chain using a passphrase. In that case, explorers like pool.pm will only see encrypted data and the message can be read only on matotam.io with the correct passphrase.
④ The NFT is sent to the recipient’s Cardano address (or ADA Handle) and appears in their wallet or on pool.pm.
⑤ This message NFT can later be burned by the original sender, the original recipient, or the matotam service address to reclaim most of the ADA locked inside.
Disclaimer
Total cost of ~2.5 ADA includes dev, network & minting fees.
Around 1.5 ADA is bound to the minting UTXO — it can be reclaimed by burning the NFT.
Messages are stored permanently on-chain.
Encrypted messages require the correct passphrase to be read. The passphrase is never stored by matotam or on-chain — if it is lost, the encrypted message cannot be recovered.
