Tokenization Engine
Tokenization infrastructure for regulated digital assets
Reusable token lifecycle capabilities — issuance, administrative controls, transfer restrictions and on-chain enforcement — designed to run inside your product environment.
Institutions repeatedly implement the same on-chain controls: mint and burn paths, freeze/unfreeze, forced transfer, whitelisting, role permissions and upgradeable administration. Doing this once per product as bespoke greenfield work recreates the same risk surface — and produces a token that only its authors understand, when the standards for this already exist.
The Tokenistry Tokenization Engine is the modular layer for those responsibilities. It is meant to sit under your investor portal, issuer workflows and business logic — not replace them.
What this module covers
- issuance and mint flows
- burn and supply controls
- freeze / unfreeze
- forced transfer / recovery
- transfer restrictions
- whitelisting & permissions
- administrative roles
- upgradeability patterns
What the contracts actually are
The token is an ERC-20 that also implements ERC-7943, the uRWA interface for real-world assets: the standardised form of the administrative operations a regulated instrument needs — forced transfer, forced burn and an absolute frozen amount — with the errors and events an integrator can rely on rather than a bespoke set invented per issuer.
Being an ERC-20 underneath is the point: custody, wallets, accounting and analytics already understand it. ERC-7943 adds the parts a security needs on top, and the interface is discoverable through ERC-165, so a counterparty can ask a token what it supports instead of taking a datasheet's word for it.
| Contract | What it is | Standards |
|---|---|---|
RWAToken |
The instrument. Mint, burn, freeze an exact amount, forced transfer for seizure or recovery, roles for each of those. | ERC-20 · ERC-7943 · ERC-2771 · ERC-165 |
ComplianceRegistry |
Permission lists the token checks on every transfer, with separate send and receive flags. Fail-closed: a registry that reverts, or a token with no list attached, denies everything. | ERC-165 · ERC-2771 |
RWATokenFactory |
Deploys each token as a beacon proxy with CREATE2, so the address is known before the transaction is mined and can be referenced in documents drafted in advance. | CREATE2 · beacon proxy |
RWATokenBeacon |
Where every token reads its logic from. One upgrade migrates an issuer's whole book; upgrade authority lives here alone, so no token role can change the code a token runs. | ERC-1967 beacon |
Two decisions worth stating plainly, because they are the ones a reviewer asks about. There is no pause function. The equivalent — and a stronger one, since it stops minting too — is detaching every compliance list, which makes the token's own send and receive checks fail closed. And the meta-transaction forwarder cannot reach the beacon, so the path that lets an investor transfer without holding native currency is not a path to the code behind their token.
Contract source can be published and verified on-chain, and the administrative and upgrade authorities are held by you rather than by Tokenistry. See eligibility and compliance for what the registry enforces, and technology for how the contracts are tested.
Tokenistry does not replace legal structuring, prospectus work or regulatory advice. The module provides technical infrastructure that must operate under those constraints.
How it fits the stack
Technical surface
The Tokenization Engine does not hold private key material. For token lifecycle operations it requests signatures through the customer's configured signing backend — AWS KMS, an HSM or a custody provider. Keys remain customer-controlled and non-exportable, with signing permissions governed by the customer's IAM and key policies. Operations are asynchronous: each returns an operation id that reaches a terminal state.
- POST /v1/tokens
- POST /v1/tokens/{token}/mint
- POST /v1/tokens/{token}/burn
- POST /v1/tokens/{token}/lists
- POST /v1/tokens/{token}/roles
- GET /v1/operations/{id}
Every mutating call carries an Idempotency-Key and returns an operation that is polled to a terminal state, so a retry returns the original operation instead of issuing a second one. Rejections before signing, conflicts and reverted executions are distinct failures rather than one generic error. The full schema is served as OpenAPI by the deployment itself.
Deployed as a container image with a Helm chart and Terraform modules, single-tenant in your own cloud account, against a PostgreSQL database you hold — see the deployment model.

Is this a full tokenization platform for issuers?
No. Tokenistry currently prioritizes the blockchain infrastructure layer used by tokenization companies. Issuer portals and product UX remain customer-owned. A Tokenistry-owned application platform is a possible future direction only if the market validates it.
Do we get the smart-contract source?
On-chain contracts can be visible and verified. Administrative keys should be customer-controlled. The proprietary IP is primarily the surrounding reusable backend infrastructure and operational architecture.
Where does this run?
Default deployment is customer-hosted single tenant inside your cloud environment, alongside your database, custody credentials and RPC access.
