The use case

Hold the reserve
in a regulated EMT.

You hold a stablecoin reserve against day-to-day obligations: settlement, payouts, working capital. The reserve asset itself matters.

EURSM and USDSM are issued under MiCA Title IV by an EU-authorised EMI. Hold them as a reserve, with a statutory right to redeem at par.

Reserve assets are safeguarded across three regulated EU credit institutions, with no single-counterparty concentration. Both EURSM and USDSM are pausable and support compliance-driven address freezing at the contract level, operationally relevant for any regulated platform operator with downstream compliance, licensing, or counterparty obligations.

The challenge

Why this matters now.

A non-compliant reserve counterparty

If your operating reserve sits in USDT, its issuer is not authorised in the EU as a credit institution or EMI. That makes it a counterparty problem, not a treasury one.

No transitional period for EMT issuers

The rule for EMT issuers has applied since 30 June 2024, with no transitional period. The transitional period for crypto-asset service providers ended on 1 July 2026 at the latest. An EMT from an unauthorised issuer cannot be offered in the EU, and ESMA's Opinion of 8 October 2026 says crypto-asset service providers should not provide services on it to EU clients.

A compliance question, not a treasury one

If you have a regulated counterparty, partner, or merchant in scope, the reserve asset stops being a yield-and-ops decision and becomes a compliance decision.

Why Stable Mint

Four capabilities
decided the reserve.

An EU-authorised EMT issuer

EURSM and USDSM are issued under MiCA Title IV by Stable Mint as an EU-authorised EMI. The reserve counterparty is a regulated financial institution, not a third-party issuer.

Statutory 1:1 par redemption

A statutory right to redeem at par under MiCA. We process redemption once onboarding and AML checks are complete.

Three-bank safeguarding

Reserve assets sit across three regulated EU credit institutions, ring-fenced from the issuer's own funds. No single-counterparty concentration.

Multi-chain, no migration

EURSM and USDSM are live on Etherlink, Ethereum, Base and Arbitrum via LayerZero V2 OFT. Same wallet, same liquidity routing, same reporting. No retraining cycle.

The verdict

Your wallet infrastructure, on-chain liquidity, and operations carry straight over from a USDT reserve. What changes is the regulatory counterparty, and everything that follows from it.

The migration

From USDT to USDSM,
in three steps.

Step 01

Confirm the USDSM contract address and approve

USDSM on Etherlink: 0x6bDE51212203aE5d592Cc5180DA2ABBd41c922dE. ERC-20 upgradeable, pausable, audited. Approve the spend on Curve v3.

Step 02

Swap USDT for USDSM via Curve v3

Execute the swap. ~$1M pool depth on Curve v3 for Day 1 migrations; Kraken added as an alternative conversion venue at scale. Instant settlement on-chain.

Step 03

Hold USDSM as your operating reserve

Use as a regulated reserve asset on your balance sheet. Redeem at par via Stable Mint when fiat is required: SEPA, SWIFT, FPS, or domestic SEK via Multitude.

Q&A

For your treasury team.

The questions your CFO, audit team, and regulated counterparties are asking, and the answers when the reserve sits in USDSM.

USDSM: full EU EMI authorisation by the MFSA, MiCA Title IV EMT issuance. The issuer is a regulated financial institution.

USDSM: a statutory right to redeem 1:1 at par under MiCA Title IV. Stable Mint processes redemption once it has accepted you as a client and AML, sanctions and screening checks are complete.

USDSM: reserve assets safeguarded across three regulated EU credit institutions, with no single-counterparty concentration.

USDSM: a regulated EMI subject to MFSA prudential supervision, with reserve assets ring-fenced from the issuer's own funds under MiCA.

USDSM: on the issuer's own authorisation. Stable Mint issues it as an EU-authorised EMI under MiCA Title IV, with no transitional period involved.

USDSM: holders have a claim against the issuer, a regulated EMI, redeemable at par. The treatment depends on your accounting policy, which your auditor reviews.

Results

What changes when you switch.

01 Audit

An issuer supervised in the EU for your audit

Your reserve becomes a claim against a regulated EMI, redeemable at par. You hand your auditor an issuer supervised in the EU and a statutory redemption right.

02 Compliance

An authorised issuer, in its own right

EURSM and USDSM are issued under MiCA Title IV by an EU-authorised EMI. Your reserve is a claim against that issuer.

03 Liquidity

Same-day redemption, six currencies

A statutory 1:1 par redemption settles same-day across six major currencies via SEPA Instant, SWIFT, FPS or domestic rails. Operating liquidity stays liquid, not locked in the reserve asset.

04 Continuity

No migration, no retraining

EURSM and USDSM are live on Etherlink, Ethereum, Base and Arbitrum. Same wallet, same liquidity routing, same reporting: the switch from USDT is a ten-minute on-chain swap, not a treasury re-platforming.

“
We had USDT, not USDC, on our balance sheet and we couldn't tell our auditors why a non-compliant issuer was the right counterparty. Moving to USDSM was a 10-minute on-chain swap. The audit conversation got simpler immediately.
