Key requirements:
• Experience with Solana smart contracts (Rust / Anchor)
• Knowledge of token launch mechanics and bonding curves
• Experience with Solana Web3 integrations
• Ability to work with an existing codebase and extend it
If this sounds interesting, please reply with:
• Your Solana development experience
• Links to relevant projects or GitHub
• Your availability for a quick discussion
Looking forward to connecting.
Best regards,
Valiant Solution LLC
