- SIWE: Sign-In with Ethereum message signature (EIP-4361)
- SIWX: Sign-In with X message signature
- SOL_SIWX: Sign-In with Solana message signature (SIWE for Solana)
- EIP712: Ethereum typed data signature following EIP-712 standard
- BIP137: Bitcoin message signature following BIP-137
- BIP322: Bitcoin message signature following BIP-322
- TIP191: Tron message signing
- ED25519: Ed25519 signature (used in Solana)
- XRP_ED25519: Ed25519 signature (used in XRP)
- XLM_ED25519: Ed25519 signature (used in Stellar)
- XPUB: Extended public key signature for HD wallets
- MicroTransfer: Proof via small blockchain transaction
- Screenshot: Image proof of ownership/access
- CIP8: Cardano message signing standard (CIP-8)
