Solana Components

White Rabbit 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) is handled server-side via the configured Solana JSON-RPC endpoint.

Connecting to Solana

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

Avoid public RPC endpoints

White Rabbit components run on shared infrastructure — all workspaces share the same outbound IP pool. Public endpoints such as https://api.mainnet-beta.solana.com enforce rate limits per IP address. Under concurrent load, shared-IP traffic can exceed these limits and cause intermittent errors, even with our load balancer in place.

Always use a private RPC endpoint from a provider such as Helius or Alchemy, or point to a self-hosted node.

Network	Example RPC
Mainnet Beta	`https://api.mainnet-beta.solana.com`
Devnet	`https://api.devnet.solana.com`
Testnet	`https://api.testnet.solana.com`
Alchemy	`https://solana-mainnet.g.alchemy.com/v2/KEY`
