# three_burn

Burn a USD-denominated amount of the $THREE your wallet holds. Quotes USD→$THREE via Jupiter, then sends ONE Solana transaction that splits it between the incinerator (burn) and the three.ws treasury, per the live public token config. EXECUTION ACTION — signs and broadcasts on Solana mainnet, IRREVERSIBLE: pass confirm:true. Capped by MAX_BURN_USD. The resolved mint is asserted to be canonical $THREE before signing. Requires a signer (SOLANA_SECRET_KEY env or the secret arg) holding enough $THREE. Returns the tx signature, the burned/treasury breakdown, and a Solscan link.

## Why three_burn is rated Critical

This tool irreversibly destroys (burns) cryptocurrency tokens, which cannot be undone. While it also involves financial value (moving cryptocurrency), the primary and defining characteristic is permanent destruction of assets. Destructive takes precedence over Financial in severity ranking.

From the tool's own definition: "Tool description explicitly states: 'Burn a USD-denominated amount of the $THREE your wallet holds', 'IRREVERSIBLE: pass confirm:true', and 'signs and broadcasts on Solana mainnet'."

Risk signals: Handles credentials or secrets (secret)
