Minting new dollars onchain is now a post-quantum decision.

If you mint on legacy signatures, you are not minting an asset. You are minting a liability with embedded cryptographic debt. Because once that dollar is widely distributed across exchanges, wallets, custody, and DeFi, there is no clean “exit” from a forced, ecosystem-wide migration later.

This is not a theory shift. It is a posture shift.
In the last 6 months:

The G7 published a coordinated post-quantum cryptography roadmap for the financial sector.

The internet is already migrating at scale. Cloudflare reports 52% of human web traffic is post-quantum encrypted.

Stablecoins are already monetary rails at global scale: $33T in transaction volume in 2025 (Artemis, reported).

Tokenized U.S. Treasuries are already a real onchain category at around $10B.

The trap most teams miss:
Post-quantum signatures impose two taxes.

Throughput tax: larger signatures and heavier verification reduce bandwidth and throughput.

Coordination tax: upgrading a live ecosystem is multi-year, fragmented, and failure-prone.

Issuer nightmare in one sentence:
Imagine a $5B stablecoin across 12 chains and 40+ venues, then a forced signature migration under stress. That is a depeg event waiting to happen.

The rule:
Mint right once. Mint PQ-native.
