• Summary: Nayms is tokenized insurance-entity plumbing. The interesting move is not “insurance onchain”; it is turning underwriting vehicles into issuers with internal ledgering, policy issuance, dividend routing, and secondary trading. Useful, but still a more operator-heavy insurance-market shell than the clearest branch anchors.
• What it does:
  • Represents companies or segregated accounts as on-platform entities that can manage multiple policies
  • Lets those entities issue participation tokens that capital providers can buy to fund underwriting portfolios
  • Supports simple-policy creation, premium payment, claim payment, and offchain-data-hash signing flows
  • Maintains internal token balances, dividend distribution, and entity-level accounting through a tokenized-vault system
  • Runs an entity-token matching market inspired by MakerOTC so platform participants can trade tokenized exposure
• Key claims:
  • The docs root says Nayms uses Ethereum smart contracts so insurance and reinsurance policies can be created, underwritten, tokenized, traded, and settled onchain
  • The docs also say entities can issue internal participation tokens that are sold to capital providers and later receive profit distributions
  • The GitHub org describes Nayms as the world’s first fully regulated marketplace for onchain insurance, with verified control of the nayms.com domain and active public contract repositories
  • The v3 contracts README shows current deployments on Ethereum and Base, plus an EIP-2535 diamond-based architecture with phased deployments and MPC involvement for mainnet upgrades
  • The public facets make the control surface legible: EntityFacet handles tokenization and token sales, SimplePolicyFacet handles policy creation/premiums/claims, TokenizedVaultFacet handles internal balances and dividends, and MarketFacet handles trading of entity tokens
• Whitepaper: The docs root links a Nayms whitepaper and token paper on DocSend, but those links were not publicly retrievable in this pass; see ../whitepapers/nayms-primary-sources-2026-05-08.md for the primary materials that were accessible.

Internal linkages

• Best upward reads: nexus-mutual and ensuro.

Control surface

• Authority sits in entity formation, privilege assignment, token-sale initiation, policy creation and claims payment, internal ledger accounting, market operation, and the diamond-based upgrade path.

• Read it as tokenized underwriting-entity infrastructure, not as the default insurance anchor.
