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.
