Overview
Zafeguard Solana components for the full transaction lifecycle — address derivation, SPL tokens, program instructions, signing, and broadcasting.
Overview
Zafeguard ships 12 Solana components covering the full lifecycle of Solana transactions: address derivation → transaction building → MPC signing → broadcasting. Includes helpers for SPL token transfers, program instruction construction, multi-party signing, and durable nonce accounts.
All network I/O (recent blockhash, balance checks, broadcast) goes through the JSON-RPC endpoint you configure on the component.

[Confirmed]Connecting to Solana
All Solana components that interact with on-chain state accept a jsonRpcUrl. Pass any standard Solana JSON-RPC endpoint.

BUILD_SOLANA_TRANSACTIONPublic RPC endpoints enforce rate limits per IP address and can fail under concurrent load.
Always use a private RPC endpoint from a provider such as Helius or Alchemy, or point to a self-hosted node.
