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.

If you are a MiCA-authorised firm, you can only hold stablecoins issued by EU-authorised EMIs. EURSM and USDSM are exactly that: hold them against any payment obligation, redeem at par to fiat in any major currency, or send directly to third-party stablecoin wallets on any supported chain.

Reserves

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

Your operating reserve most likely sits in a stablecoin from an issuer with no EU EMI authorisation under MiCA Title IV. For a MiCA-authorised firm, that is now a counterparty problem, not a treasury one.

No grandfathering from July 2026

Transitional grandfathering closes at the end of June 2026. From July 2026 there is no exemption: a stablecoin from any issuer without EU EMI authorisation under MiCA Title IV is an unregulated counterparty, and can no longer be held as a reserve by a MiCA-authorised firm.

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 redemption right at par under MiCA, a counterparty obligation rather than discretion. The prior non-compliant stablecoin gave you neither.

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

USDSM is 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: 1:1 par redemption right under MiCA Title IV. A counterparty obligation, not counterparty discretion.

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: out of scope of grandfathering. It already meets the post-cliff requirement.

USDSM: treated as a claim against a regulated EMI, redeemable at par. A cleaner audit position than a claim against a non-compliant stablecoin issuer.

Results

What changes when you switch.

01 Audit

A cleaner audit and balance-sheet position

Your reserve becomes a claim against a regulated EMI, redeemable at par, rather than against a non-compliant stablecoin issuer. The audit conversation gets simpler and the balance-sheet treatment cleaner.

02 Compliance

MiCA-authorised, not grandfathered

EURSM and USDSM are issued under MiCA Title IV by an EU-authorised EMI, never reliant on transitional grandfathering. The reserve meets the requirement in its own right, not on a temporary exemption.

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

USDSM is 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.
