Today: SDA Token Completes Its Four-Authority Renouncement
Today, 18 May 2026, SDA Token will complete something few token issuers ever do — voluntarily destroying every administrative power the issuer holds over the token after issuance.
What burns today
Two issuer authorities still exist over SDA as of this morning. They are revoked permanently on-chain today:
- Freeze authority — until today, we could technically lock any SDA wallet. After today, that ability is gone forever.
- Transfer-hook authority — until today, we could attach programmable rules that run between sender and receiver. No hook is currently attached, but the option still existed. After today, even the option is gone.
What was already burned
Two more authorities were burned at the mint and have been gone the entire time:
- Mint authority — supply is permanently fixed at 100,000,000 SDA. We cannot mint more. Ever.
- Metadata authority — the token's name, symbol, image and URI are immutable.
Why this matters
Most Solana token issuers keep these authorities indefinitely — "just in case." The polite framing is flexibility. The honest framing is that the team retains the ability to change the rules after holders are already exposed.
We are taking the opposite approach. 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 itself.
Verify on-chain
Don't take our word for any of this. The state of these authorities is public, queryable in one command:
spl-token display SDAmxfpgaGmtxTqcTcvr4yi2kBwEFxTLF2XU4oLFw4b --url mainnet-beta
You will see mintAuthority: null and tokenMetadata.updateAuthority: null already, and freezeAuthority and transferHook.authority flipping to null today. The burn transaction signatures will be posted publicly the same day.
