Terra/Luna pioneered the right vision (decentralized stablecoin, permissionless monetary policy, DeFi-native rails) but coupled it to fatal mechanics. STELLA keeps the vision and removes every failure mode that killed Luna, in code, on day one.
| Luna failure | STELLA mitigation |
|---|---|
| Algorithmic-only backing → death spiral | 100% USDC-backed. No volatility-absorbing partner token. |
| Anchor 20% subsidized yield → ponzi | Zero native yield. Yield contracts are separate, opt-in, real-revenue only. |
| 75% of UST in one protocol | Hard supply cap ($100k initial). Raised only by 48h-timelocked vote. |
| No circuit breakers | pokePause() — anyone calls — auto-halts mint if ratio < 110% or peg < $0.97. |
| $1.5B BTC reserves vs $18B UST (8% backing) | ≥150% required to mint. Verifiable via collateralRatioBps() on-chain. |
| Do Kwon centralization | No admin keys. Multisig 5-of-9 governor with 48h timelock. Cannot mint, freeze, or touch user funds. |
| Wormhole-class cross-chain attack surface | Single chain (Base). No cross-chain bridges in this contract. |
| Forced de-peg via liquidity attacks | Redemption is direct-to-USDC, never depends on DEX liquidity. Cannot be paused. |
You send USDC, you get STELLA at $1. You burn STELLA, you get USDC back at $1. Anyone can mint when treasury collateral ≥ 150%. If ratio drops below 110% or USDC itself depegs below $0.97, anyone calls pokePause() and minting stops. Redemption keeps working — by design, no function exists that can freeze it. The governor (multisig) can only queue 48-hour-delayed changes to the supply cap, governor address, or unpause flag. They cannot mint, burn, or touch user funds. Code is immutable; no upgrade proxy.
The Luna model killed Terra: UST's peg defended by infinite LUNA mint → death spiral. STELLA refuses that pattern. STELLA is fully backed by USDC in contract custody, period. AIGEN's role is the MakerDAO/MKR-style support layer:
| Role | Mechanism | Hard limit |
|---|---|---|
| Governance | AIGEN holders vote on supplyCap + parameters via 48h timelock | No mint power, no fund access |
| Work coordination | AIGEN bounties pay agents for peg defense (arb, monitoring, audits) | Bounded by AIGEN protocol revenue |
| Fee capture | STELLA fees → AIGEN treasury → buyback | Unidirectional: STELLA functions without AIGEN |
| Insurance fund | Staked AIGEN absorbs bad debt if STELLA backing < 100% | Hard cap 5% of STELLA supply — no infinite mint |
If AIGEN crashed to $0 tomorrow, STELLA would still be backed by the USDC in its contract. The reverse isn't true for UST/LUNA — that's the death-spiral architecture STELLA refuses.
