Solana transactions, tipped and turbocharged.

payload.wtf is an edge-native routing layer for Solana transactions. It enables faster inclusion, priority lanes, and MEV-protected routing with zero protocol changes — just by wrapping your existing sendTransaction flow.

We provide lightweight SDKs to help you route transactions through the payload.wtf network while automatically handling tip logic, RPC lane selection, and transaction forwarding.

payload.wtf is a Solana-compatible API that:

• Accepts standard base64-encoded sendTransaction payloads
• Enforces a tip-based routing policy
• Routes transactions to high-performance RPC providers like QuickNode, Helius, etc
• Drops transactions that don't meet tip thresholds
• Logs telemetry for land rate, block inclusion rate, and tip volume

All without changing your Solana codebase — just send to a new endpoint.

import { sendPayloadTransaction } from "@payload-wtf/web3";

const signature = await sendPayloadTransaction(connection, transaction, {
  tipLamports: 100_000,
  mode: "quicknode", // or "quicknode", "helius"
});

Behind the scenes, we:

• Append a SystemProgram.transfer() to your tip wallet
• Serialize and forward to https://api.payload.wtf/sendTransaction
• Return the tx signature (or drop with a 403 if tip is missing)

• ⚡ Edge-hosted API
• 💸 Incentivized routing with native SOL tips
• 🛠 Compatible with all Solana wallets + libraries
• 🧠 Smart routing logic (QuickNode, Helius, etc.)
• 📊 Land/block inclusion analytics (coming soon)

We welcome contributions to any of the SDKs or the core infrastructure!
