Testnet deployments

Do not hardcode addresses in your app; read them from the SDK. All bundled addresses come from one generated package, @opaquecash/deployments, which the chain repos emit from their canonical deployment records:

Source of truth	Generator	Output
`ethereum/infra/deployments/*.json` + hardhat artifacts	`npm run generate` in `ethereum/infra`	EVM addresses + contract ABIs
`solana/Anchor.toml` program tables	`npm run generate` in `solana`	Program ids + Wormhole core per cluster
`starknet/deployments/*.json`	`node scripts/generate-deployments.mjs` in `starknet`	Starknet addresses + class hashes per network

A redeploy is therefore a regenerate + rebuild, never a code change. Higher SDK packages (@opaquecash/opaque, uab, stealth-chain-solana, stealth-chain-starknet, psr-chain, psr-chain-starknet) and the reference app all source their addresses from it.

Reading addresses

Most apps use the convenience getters re-exported from @opaquecash/opaque:

import { getChainDeployment, getSolanaDeployment } from "@opaquecash/opaque";

const evm = getChainDeployment(11155111);   // registry, announcer, verifier, tokens
const sol = getSolanaDeployment("devnet");  // program ids as PublicKey

Or read the registry directly (string ids, zero dependencies):

import {
  requireEvmDeployment,
  requireSolanaProgramIds,
  stealthAddressAnnouncerAbi,   // generated ABIs ship here too
} from "@opaquecash/deployments";

const evm = requireEvmDeployment(11155111);
// evm.contracts.{stealthMetaAddressRegistry, uabSender, ...}, evm.wormhole, evm.tokens

const sol = requireSolanaProgramIds("devnet");
// sol.{stealthRegistry, stealthAnnouncer, uabReceiver, wormholeCore, ...}

Override any address per client via OpaqueClient.create({ contracts: { ... } }).

Supported chain IDs

OpaqueClient.supportedChainIds();  // [11155111] in the current SDK version

This enumerates EVM chain ids only. The non-EVM chains are read through their own getters — getSolanaDeployment("devnet") and getStarknetDeployment("sepolia") — and do not appear in this list. Mainnet addresses will land in the same registry when they deploy: the chain repos run npm run generate against the mainnet records, and every consumer picks them up on rebuild.
