MAGMA Shield — Overview
MAGMA Shield is a yield-bearing conviction market for DeFi protocol security. It lets capital holders stake conviction on whether a specific protocol will be exploited during a defined coverage window — and earn DeFi yield throughout that window regardless of the outcome.
Shield runs against the live Solana devnet deployment of magma_shield_vault
(program ID 4ri6AGT37GrL6mzuFdeVc6Wa2H7Q7srnCsQjkGj4v7my). Several parameters are
relaxed on devnet and tightened for mainnet — see Shield Technical
Specification.
The problem
DeFi exploits are frequently predictable. The community often identifies vulnerabilities — weak multisigs, unaudited contracts, centralized admin keys — weeks or months before an attack lands. What has been missing is a market mechanism to stake that conviction with capital behind it.
A recurring pattern in 2026 has been a publicly-flagged 2-of-5 multisig weakness that the community discussed openly, yet had no venue to back financially before the exploit occurred. Shield exists to close that gap.
The solution
Shield creates structured conviction markets on protocol security events. Backers choose SAFE or EXPLOIT, commit capital, and earn DeFi yield for the full coverage window. An oracle consensus mechanism resolves the outcome. Correct backers earn back their principal, the accumulated yield, and a conviction multiplier; the losing side forfeits principal but keeps the yield already earned.
Two-tier system
Shield operates on two tiers — an open Community tier and an application-gated Partnership tier.
| Community Shield | Partnership Shield | |
|---|---|---|
| Access | Open — any protocol | Application required |
| Arcium confidential mode | Optional toggle | Enabled by default |
| Minimum coverage | 5 SOL to be featured | $25,000 USD equivalent |
| Partnership fee | None | 0.5% of coverage volume / 90 days |
| EXPLOIT split | 58% backers / 39% MAGMA / 3% Seam | 50% protocol / 35% backers / 12% MAGMA / 3% Seam |
| Shield badge | No | Yes — official badge |
| SIRN escalation | No | Yes |
| Self-backing | No | Yes — protocol can back its own SAFE pool |
| First period | — | Free |
See Shield Economics for the full payout split tables and Partnership Guide for the onboarding process.
Coverage tiers (badges)
Protocols earn a tier badge based on cumulative backing volume. Badges are visible on the protocol's Shield page and may be displayed externally by Partnership protocols.
| Badge | Backing volume |
|---|---|
| Spark | < $100K |
| Flame | $100K – $500K |
| Magma | $500K – $2M |
| Volcanic | > $2M |
How a coverage window flows
Key properties
- Capital earns yield from commitment. SOL is routed to approved DeFi protocols the moment it is committed.
- Yield is never clawed back. On a losing position only the principal redistributes; the yield earned during the window is retained by the backer.
- Both sides earn yield. SAFE and EXPLOIT backers both accrue DeFi yield throughout the window.
- Early conviction is rewarded. A 2.0× Discovery Multiplier applies to the conviction score component for backers who commit during the discovery window.
