Deployments

Contract addresses for every supported test network, including the Latheon test chain, generated from deployments.json, the registry the demo uses. Addresses are network-specific: the same address on another network is a different contract.

Circuits and parameters

Groth16 proofs. Proving keys come from a single-operator development setup and are suitable for testnets only.

withdraw_v5

Used by the current V7 pools. Public inputs: root, nullifierHash, recipient, relayer, fee. Every step of the Merkle path is constrained to 0 or 1 (the fix for the pre-V7 flaw). Older pools used withdraw_v3 (V5) and withdraw_v4 (V6).

disclose

Public inputs: commitment, disclosureTag, auditorNonce. Checked by a read-only call to the disclosure verifier.

Pools

Sizes 100 / 50 / 10 / 1. V7: Merkle tree depth 20, up to 1,048,576 deposits per pool, root history 100. Old V5 pools: depth 8, 256 deposits, root history 30.

The JavaScript SDK in sdk/ still targets the V3 pool; updating it for V7 is on the roadmap. The demo is the current reference for V7.
