What this does
One threshold, held in your own token, decides two things: who may reply to you, and who may read the casts you mark holders-only. The number lives onchain, so nobody running ponsocial can raise or lower it. It is checked against each reader's custody wallet, never a delegated key.
Worth knowing before you rely on it: this is access control, not encryption. A holders-only cast is stored on ponsocial's own server, which refuses to serve it to people who do not hold — but the operator can read it, and anyone who held the token while it was posted has already seen it.
