Now that SUP is transferable and yield is actively accumulating, I think it’s worth revisiting the buyback discussion that was deferred in SIP-9.
The original projection was ~$90K/year across all assets. Looking at on-chain data today, the Base deployment alone is generating around $29/day (~$10,500/year) with ~419K USDC in Aave at ~2.5% APY — still below the original estimate, but real and growing.
The case for starting now is actually stronger at current SUP prices: each dollar of buyback captures more tokens, making this arguably the most efficient time to begin. A small, consistent buyback doesn’t need to move markets — it establishes a rhythm and starts the flywheel SIP-9 originally envisioned.
Could the DAO consider allocating a modest portion of yield — say 25–50% — to an ongoing SUP buyback, and reassess after a few months? Starting small keeps risk low while giving us real data to build on.
