The missing layer
A screenshot says what was visible.
A receipt proves what was signed.
DealSeal binds the authenticated X account in the deal room to a Solana wallet over the same canonical bytes. Neither side can quietly change the purpose, wallet, counterparty, or expiry.
Sign identical bytes
Your authenticated X message and wallet signature cover a deterministic tuple: parties, purpose, wallet, origin, nonce and expiry.
Keep portable evidence
The receipt is signed by DealSeal and includes event hashes, wallet signatures, key fingerprints and continuity evidence.
The observatory
Time is evidence.
Opted-in accounts build an append-only history of X Chat key versions and wallet bindings. Daily Merkle roots make the record difficult to rewrite after the fact.

DealSeal proves authenticated X messages and matching wallet signatures were observed.
DealSeal does not prove legal identity, asset quality, authority, delivery, or that an account was uncompromised.
