SDA Token — the last two issuer authorities burn todayToday,
18 May 2026, we revoke the last two administrative authorities on SDA Token (Solana SPL Token-2022):
- Freeze authority — losing the ability to lock any SDA wallet
- Transfer-hook authority — losing the ability to insert programmable rules between sender and receiver
The mint authority and metadata authority were already burned at launch — supply is permanently fixed at 100,000,000 SDA and the token's identity (name, symbol, image, URI) is immutable.
After today, every SDA in self-custody answers only to its holder. Where regulatory enforcement applies, it sits at the exchange or custodian layer — not inside the token contract.
