Do NIST post-quantum signature standards automatically work for Bitcoin wallets today?

No. NIST has standardised schemes such as ML-DSA and SLH-DSA, but their existence does not make Bitcoin consensus accept them for ordinary outputs. Adoption would require appropriate protocol support and wallet implementations.

What to do next

Differentiate a product’s local cryptography from the signature algorithms actually verified by Bitcoin nodes.

Frequently asked questions

Could wallet firmware alone add ML-DSA spending to Bitcoin?

Not as a universally valid new transaction type unless the chain’s verification rules support the required signatures.
