Cardano Foundation ships CIP-0113, letting token issuers freeze and seize holdings

The Cardano Foundation said Wednesday that a token standard it files as a Cardano improvement proposal, CIP-0113, is live on the network following independent security audits. The standard lets issuers of stablecoins, funds and bonds decide who can receive their assets and gives them the power to freeze or seize holdings when the rules require it, CoinDesk reported. The foundation is a Swiss nonprofit that supports Cardano's development.

Most crypto tokens can be sent by anyone who holds them to any wallet, which suits a bearer asset and rules it out for regulated issuance. Banks and fund managers moving assets onchain have to keep tokens away from buyers who have not passed identity checks and from sanctioned addresses, and they have to be able to freeze a position when a regulator or a court orders it.

CIP-0113 builds those controls into the token instead of asking every venue to apply them at the door. Tokens sit in a shared smart contract, a program on Cardano that governs how they can be moved, and the computers checking transactions enforce the issuer's chosen rules before accepting a transfer. A fund sold only to verified investors could reject a transfer to someone who has not completed identity checks; a stablecoin issuer could stop its tokens from reaching a sanctioned address. The restrictions apply whenever the tokens move, including between holders using different wallets or services.

The design shifts where the screening burden sits. With an ordinary token, the issuer records who subscribed and each venue screens onward transfers as they arrive; with the tokens CIP-0113 governs, the balance sits in a contract that can be told to refuse one, so the rule travels with the asset and the refusal happens in the transfer logic itself. For an issuer selling through several wallets and services at once, the appeal is that the same rule applies in each of them, an argument about consistency rather than about any single venue's controls.

The foundation says the approach uses capabilities Cardano already had and required no hard fork, a change to the network's underlying rules. That distinction suggests application-layer standards can ship on an issuer's calendar while rail-level changes wait on the network's own governance, an inference from the architecture rather than a claim the foundation made.

Rule sets are the operative unit. Issuers can select from existing sets or write their own, and can revise them as regulations change. "The rules have to travel with the asset and be enforced every time it moves," Frederik Gregaard, the foundation's chief executive, said in a statement to CoinDesk.

Cardano did not reach permissioned tokens ahead of the market. Ethereum has permissioned token standards including ERC-3643, Solana added transfer controls through its token extensions, and the XRP Ledger supports tokens whose issuers can restrict holders and claw back balances, according to CoinDesk's account. Against that record the launch roster carries as much weight as the mechanism: the foundation named wallets Eternl and GeroWallet, blockchain explorer CardanoScan and developer-tool provider BloxBean among the tools supporting the release.

Because the restrictions are meant to hold wherever the tokens move, the wallets and services that carry them become part of the compliance perimeter, which is a likely reason the announcement leans on tooling rather than on named issuers. No fund, bond or stablecoin issuer using the standard appears in the coverage of the launch.

Blocking a payment is the most visible of the powers these tokens carry, and it is not the only one. Depending on its rules, an authorized party could move tokens without the holder's consent, and the technical specification tells lending services to examine those powers before accepting a token as collateral. A desk weighing such a token as security is taking a claim on an asset whose issuer may, under the chosen rules, be able to move it — a diligence question before it is a pricing question.

For an allocator, the trade-off sits in the rule set. A permissioned token hands the issuer an allow-list and a power of seizure, and asks the buyer to accept that the asset's rule set, rather than the buyer's custody arrangement, governs what can happen to the position. Issuers can update that rule set as regulations change, which suggests the terms in force at purchase are not necessarily the terms in force a year later.

The same controls have a commercial reading on the stablecoin side, where an issuer able to stop its tokens reaching a sanctioned address at the token level has one fewer control to build into its own transfer path. The foundation frames the standard as a compliance tool; the distribution argument is an inference from the architecture.

What the launch establishes is that Cardano's issuers can write enforceable rules into a token without the network changing its own rules. What it does not establish is demand. No issuer is named, and the test is whether a fund, stablecoin or bond issuer writes a rule set into a Cardano contract, and whether a lending desk reads that rule set before accepting the token as collateral.
