cns

Convex Name System (CNS)

CNS maps human-readable names (like convex.fungible) to on-chain addresses.

Resolve a Name

Use mcp__convex-testnet__resolveCNS with the name.

Returns: value (usually an address), controller, metadata, and child node.

Register or Update a Name

Transaction: (call #9 (cns-update 'my.name address))

• #9 is the CNS registry actor
• The name must be under a namespace you control
• Top-level names require special authority

CNS in Code

• @convex.fungible in CVM source resolves to the actor address at runtime
• Use CNS paths instead of hardcoded addresses for portable code
• (@convex.fungible/balance #TOKEN #USER) calls balance on the resolved actor

Common CNS Names

| Name | Purpose | |------|---------| | convex.fungible | Fungible token standard library | | convex.trust | Trust and access control | | convex.asset | Multi-asset interface | | convex.nft | Non-fungible token support |
