Tonsurance
TON-native DeFi insurance: capital pools cover smart-contract exploits, stablecoin depegs, and oracle failures. As of May 2026 — niche, low TVL, a narrow coverage catalogue.
Aliases: tonsurance, defi insurance on ton
Tonsurance is a TON-native decentralised insurance protocol. A user buys a “policy” against a specific risk (contract exploit, stablecoin depeg, oracle failure), and capital providers earn premiums for underwriting the risk.
What it covers (as of May 2026)
- Smart-contract exploits against whitelisted DeFi protocols.
- Stablecoin depegs below a defined threshold (e.g. below $0.95 sustained for 24h).
- Oracle failures that triggered liquidations.
What it does NOT cover
- Staking slashing.
- Social engineering and phishing (that’s user-side security, not systemic risk).
- Exchange bans or sanctions.
- “Rug pull” (deliberate team exit) — contested category, usually excluded.
Limitations
- Small TVL → high base premium per unit of coverage.
- Narrow whitelist of covered protocols.
- Claim governance: payout decisions go through multisig / voting, with dispute risk.
Alternatives
- Multi-chain insurance (Nexus Mutual, InsurAce) — TON protocols are covered only via wrapped exposure, indirectly.
- Self-insurance: diversification and a personal reserve fund.
