Solayer Chain uses a DApp-first model that shifts transaction broadcasting from wallets to DApps. This means any Solana-compatible wallet works with Solayer Chain without requiring native chain support.

​
EVM vs SVM Approach

EVM (wallet-dependent):
  • EIP-155 requires chain ID in the signature payload
  • Each wallet must explicitly support each chain
  • Wallets are responsible for broadcasting
Solayer Chain (DApp-first):
  • SVM signatures do not include chain IDs
  • Transactions reference a recent block hash, automatically rejecting cross-chain replays
  • DApps handle broadcasting — wallets don’t need modification

​
Solayer Chain SDK

Using the Solayer Chain SDK, DApps can generate and sign transactions compatible with any Solana-based wallet without:
  • Native wallet support for Solayer Chain
  • Explicit chain ID handling
  • Wallet-driven broadcasting logic
Benefits:
  • Any Solana-compatible wallet works with Solayer Chain DApps out of the box
  • No wallet updates needed — DApps handle all chain-specific logic
  • Native wallet support improves asset visibility but is not required for transaction execution
