📄 Description

Closes #6738

Implemented multi-chain wallet authentication supporting both EVM and Solana chains via a unified plugin based on the SIWX spec.

Unlike the SIWE plugin, this plugin does not currently have core schema changes. This is intentional based on conversation in #6738, but I can change this if there is strong community consensus otherwise.

More notes WIP nvm wow cubic is awesome

Summary by cubic

Add a new SIWX plugin as a dedicated @better-auth/siwx package to enable multi-chain wallet sign-in for EVM and Solana, with nonce/verify endpoints and optional native wallet callbacks. No core schema changes.

  • New Features

    • Dedicated @better-auth/siwx package and client export.
    • POST /siwx/nonce issues a 15‑min nonce with statement and default chainIds (evm=1, solana=mainnet-beta).
    • POST /siwx/verify builds a CAIP‑122 CACAO, calls verifyMessage, links/creates user and session; supports anonymous or email-required flows; optional signatureType (defaults: evm:eip191, solana:ed25519).
    • EVM checksum normalization, CAIP‑10 issuer, cross‑chain address linking.
    • Optional nameLookup for display name and avatar.
    • GET /siwx/callback/:provider (phantom, solflare, backpack) decrypts payload and signs in with configurable success/error redirects.
    • Added docs and comprehensive tests.

  • Bug Fixes

    • Safer success/error redirect URL construction in native callbacks.
    • Fixed callback account creation to reliably link wallets and start sessions.
    • Calculate nonce expiration once to avoid drift.

Written for commit da96ad61e4. Summary will update on new commits.
