createSpendingPolicy(params): SpendingPolicy

Defined in: src/policy/spending-policy.ts:188

Validate + normalize a SpendingPolicy. Checksums all addresses (getAddress), de-dupes the recipient allowlist (shared normalizeRecipientAllowlist; [] stays deny-all), rejects an empty perToken (deny-closed), a non-positive maxPerSign/cumulativeCap, a cumulativeCap < maxPerSign, and duplicate tokens. Throws SpendingPolicyConfigError on violation.
