Start wallet registration / login
auth_wallet_challengeStep 1 of registering (or logging in) a user with a wallet keypair — no browser needed. Returns a challenge message to sign with the wallet's private key. Works for Solana (base58 Ed25519 address) and EVM (0x address). Follow with auth_wallet_verify. New wallets are auto-registered on first verify as a free account (a daily allowance + 3 runs; the Studio, $249 a month, lifts the caps).
