A deposit to a wormhole address is spent when its nullifier, poseidon2(poseidon2(salt || secret || transfer_count)), is in Wormhole::UsedNullifiers. Working out a wormhole balance means computing one for each deposit. That needs the address's secret, which never leaves WASM. wormholeNullifiers(mnemonic, password, account, branch, start, addresses, first, count) returns them for a run of addresses and a run of transfer counts. The BIP39 seed is stretched once per call; 40 addresses x 256 counts takes 194 ms in node. A call is capped at 100,000 nullifiers. This is ported onto qp-poseidon-core, not qp-wormhole-circuit, which would bring plonky2 into the WASM. The circuit crate is a dev-dependency only, as the reference: a known-answer test compares the port with Nullifier::from_preimage across secrets at and above the Goldilocks-prime limb edge and transfer counts across both 32-bit limbs, and asserts that enough cases were actually compared rather than skipped. The doc comments say to check nullifiers against a local copy of the spent set, never by key: exits publish nullifiers, so a lookup names the exit.
