@odatano/contract-token-factory

Shielded tokens on demand: one deploy serves any number of tokens, each named by its issuer.

• domain = persistentHash(["tokenfactory:domain", issuerKey, name]), token type = tokenType(domain, contractAddress). Another issuer or another name is another type.
• issuerKey = persistentHash(["tokenfactory:issuer", secret]); the secret stays with the issuer as the issuerSecret witness, so nobody else mints more of a token.
• mint(name, amount, recipient) mints to any Zswap coin public key and keeps issuer, name and circulating supply in the public ledger map tokens.
• burn(domain, coin) takes coins out of circulation and lowers the supply.
• No transfer logic: coins move with Zswap itself, so swaps settle without a contract call.

import { Contract, ledger, pureCircuits } from '@odatano/contract-token-factory';
import { tokenTypeOf, prepareMint, prepareBurn, tokenName } from '@odatano/contract-kit';

const { domain, type } = await tokenTypeOf(pureCircuits, { issuerSecret, name: 'CREDIT', contractAddress });

A known deployment on preprod: d96fcca18b3ca748af0c0934d88a47113bb52e586afe334f3d9f5e66e5aea02c (deploy transaction 007fd4723a6f3cd0a442f58869e8f05b8247dee3d28870496b0e14832b8cf01252). Its verifier keys are the ones this package ships; a recompile with another compiler or runtime is a new verifier-key set and a new deployment.

Prover keys are not in the package: keys/manifest.json pins their bytes, contract.json#zkAssetUrl names the release assets.

Peer dependency: @midnight-ntwrk/compact-runtime at the exact version in contract.json#compactRuntime.
