Reuse verification

When someone already holds a proof that meets your rule, Proofable accepts it and skips the check.

How reuse is decided

Find existing proofs

Proofable looks for proofs the person or agent already holds for each required check.

Confirm they are current

Expired and revoked proofs never count. Point-in-time checks, such as a token balance or wallet risk, must be recent enough for your rule.

Confirm they fit this rule

A stricter rule can need a new check. A basic proof of human does not satisfy a gate that also requires a minimum age.

Pass, or verify only what's missing

If every requirement is covered, the person continues. If not, they complete only the missing checks.

Reuse in your product

Where	How
React	`VerifyGate` reuses a saved proof by default (`strategy="reuse-or-create"`).
Your server	`gateCheck` returns `allRequiredSatisfied` and which checks were satisfied or missing.
An AI assistant	`proofable_proofs_check` answers yes or no without creating anything.
New proofs	Pass `reusedVerifierProofs` from the gate check so satisfied checks are not run again.

const { data } = await client.gateCheck({
  gateId: 'gate_your-app-name',
  address: user.accountAddress,
  includeQHashes: true,
});

if (data?.gate?.allRequiredSatisfied !== true) {
  // Ask the person to verify data.gate.missingVerifierIds
}

Signed-in owners checking their own proofs through MCP pay nothing.

Private proofs

Gate checks read public and unlisted proofs by default. A private proof counts when its owner is signed in, or when you pass a signed payload from createGatePrivateAuth. Gates in the SDK
