Add the tip before signing

Include a System Program transfer to one accepted account in the same transaction as your application instructions. The private minimum is 150,000 lamports.

// @solana/web3.js: add before setting the blockhash and signing.

Tips and network fees

The tip pays for the sender path. The base fee and any priority fee pay Solana validators and are additional. A priority fee uses Compute Budget instructions and does not replace the tip.

The tip is an on-chain transfer within your signed transaction. Track the final transaction result on-chain; an API response is not a billing or execution receipt. If the same signed transaction is also sent through another provider and lands there, the embedded tip still belongs to that transaction.

Public access

A public route is available at https://sfls.l2.p2p.org/public: no API key, minimum tip 200,000 lamports (0.0002 SOL), 1 request/s per source IP, sendTransaction only. This is paid tip-based access, not a free trial. Supanode-issued keys unlock private-profile limits.

Sending transactions covers errors and retry handling.
