CAIP-2 chain reference for non-EVM signature verification (e.g. solana:mainnet)
Signature method hint for non-EVM signatures (e.g. ed25519)
^0x[a-fA-F0-9]{64}$1 <= x <= 10001 <= x <= 3650x >= 01 <= x <= 1000EVM chain ID of the asset being checked (e.g. 1 for Ethereum Mainnet, 8453 for Base). Required for asset verifiers (nft-ownership, token-holding, contract-ownership). Not a hub or proof-storage filter.
x >= 1When set, requires ownership-pseudonym proofs to include this namespace (matches verifier data.namespace; legacy proofs without namespace default to neus).
