If your execution depends on transaction landing, set up speed matters.
Syncro Sender is designed to integrate directly into your existing flow with minimal changes. You can start sending transactions in minutes using either a public or a private endpoint.
This guide walks through how to set up Syncro Sender and start sending transactions immediately. For a full technical reference, see the Syncro Sender documentation.
Before using Syncro Sender, make sure you have:
Syncro Sender is used for transaction delivery, not simulation or state queries.
Syncro Sender supports two access modes.
Available endpoints:
http://sfls-geo-fra.l2.p2p.org/publichttp://sfls-geo-nyc.l2.p2p.org/publichttp://sfls-geo-lon.l2.p2p.org/publichttp://sfls-geo-tky.l2.p2p.org/publichttp://sfls-geo-sgp.l2.p2p.org/publichttp://sfls-eu1.l2.p2p.org/publicTo get access, request it via the Syncro Sender page or contact the team.
A tip is required for both public and private endpoints.

Add a System Program transfer instruction to a valid tip account:
transaction.addInstruction(
SystemProgram.transfer(
yourPublicKey,
'BPZrtYhdoAhiHWV5EgGLoV7bZFbMamBZurGDq4DmST8v',
100000
)
);transaction.addInstruction(
SystemProgram.transfer(
yourPublicKey,
'BPZrtYhdoAhiHWV5EgGLoV7bZFbMamBZurGDq4DmST8v',
100000
)
);
Error example:
"Insufficient tip: provided X lamports, required Y lamports"
curl -X POST <https://sfls.l2.p2p.org/public> \\
-H "Content-Type: application/json" \\
-d '{
"jsonrpc": "2.0",
"id": 1,
"method": "sendTransaction",
"params": ["<BASE64_ENCODED_TX_WITH_TIP>", {"encoding": "base64"}]
}'
Private endpoint request
curl -X POST <https://sfls.l2.p2p.org> \\
-H "Content-Type: application/json" \\
-H "Authorization: Bearer YOUR_API_KEY" \\
-d '{
"jsonrpc": "2.0",
"id": 1,
"method": "sendTransaction",
"params": ["<BASE64_ENCODED_TX>", {"encoding": "base64"}]
}'
Response
{
"jsonrpc": "2.0",
"result": "<TRANSACTION_SIGNATURE>",
"id": 1
}
Once integrated, test Syncro Sender alongside your current setup.
Focus on:
Use your standard RPC to monitor transaction status. Private endpoint users can also use Syncro Sender for all standard Solana RPC requests, including status checks and confirmation queries.
To get the best results:
skipPreflight: true to reduce latencySubmitting the same transaction multiple times is safe.
| Use case | Recommendation |
|---|---|
| Testing | Public endpoint |
| Production trading | Private endpoint |
| High frequency workflows | Private endpoint |
Syncro Sender does not change your transaction logic.
It changes how your transactions are delivered.
That means:
You can start immediately using the public endpoint.
For production use cases, request access to the private endpoint.

No. The public endpoint requires only a tip of 0.0001 SOL in the transaction.
The transaction will be rejected with an error.
Only on private endpoints with this feature enabled.
Use a standard Solana RPC method such as getSignatureStatuses.
Base64 encoding is required and recommended.

SEC and CFTC Issue Joint Landmark Interpretation Clarifying Crypto Asset Classification</strong></h2><p>On March 17, 2026, the SEC and CFTC jointly issued an interpretation establishing the most consequential token taxonomy in U.S. regulatory history. The guidance introduced five categories, including digital commodities, digital collectibles, digital tools, stablecoins, and digital securities, and explicitly clarified that protocol staking across all four models (solo, self-custodial, custodial, and liquid staking) does not constitute a securities transaction. Protocol mining received the same treatment.</p><p>For the staking ecosystem, the ruling ends more than a decade of enforcement-driven ambiguity. Custodial staking arrangements are now defined as ministerial activities. Liquid staking providers issuing receipt tokens are explicitly outside securities law, provided they do not fix or guarantee reward amounts. ETH, SOL, ADA, and 13 additional assets were classified as digital commodities under CFTC jurisdiction.</p><p>Source: <a href="http://sec.gov/?ref=p2p.org">SEC.gov</a> —> <em>SEC Clarifies the Application of Federal Securities Laws to Crypto Assets</em> (March 17, 2026)</p><h3 id="why-relevant-for-validators-and-the-staking-ecosystem"><strong>Why relevant for validators and the staking ecosystem:</strong></h3><ul><li>Protocol staking is now explicitly classified as a non-securities activity across all four operational models</li><li>Custodial staking service providers have a clear operational framework: act as agent, do not determine staking amounts or fix rewards</li><li>Liquid staking receipt tokens are legally defined, removing the investment contract ambiguity that had deterred institutional liquid staking deployment</li><li>Clears the path for staking ETF products on any of the 16 named digital commodity assets</li></ul><h2 id="2-blackrock-launches-ethb-first-major-staking-integrated-ethereum-etf"><strong>2.

The product stakes between 70% and 95% of its ETH holdings through Coinbase Prime and third-party validators, distributing approximately 82% of gross staking rewards monthly to investors. ETHB launched with $107 million in assets and approximately 80% of its ETH already staked on-chain on day one.</p><p>The structural significance extends beyond Ethereum.

The approval makes Kraken the first crypto-native firm in U.S. history to settle dollar payments directly on Fedwire — the same rails used by JPMorgan and Bank of America — without routing through intermediary correspondent banks.</p><p>The account carries restrictions: Kraken will not earn interest on reserves, cannot access the Fed's discount window, and operates under a one-year initial term.

<h2 id="what-actually-happens-between-submission-and-execution">What actually happens between submission and execution</h2><p>Speed is often treated as the defining feature of Solana.</p><p>What is less understood is what happens between submission and landing, and why two transactions sent at the same time can end up with completely different outcomes.</p><p>For teams running execution-critical workflows such as arbitrage, liquidations, or high-frequency strategies, performance is not defined by how fast a transaction is sent. It is defined by whether it gets to the leader in time.</p><p>These are the observations we made while building Syncro Sender, P2P.org's Solana transaction sender built for execution-critical teams. We are sharing them here because the patterns we found are not specific to our infrastructure. They reflect how Solana transaction delivery works at the network level.</p><p>Our <a href="https://p2p.org/economy/solana-transaction-landing-speed-routing/">previous post</a> reframes the problem: Solana transaction landing is not a speed problem, it is a routing problem. This post goes one level deeper and explains the system behind it: what the delivery path actually looks like, where it breaks, and what changes when you build infrastructure around it.</p><h2 id="quick-lessons-for-builders">Quick Lessons for Builders</h2><ul><li>Transaction landing depends on delivery, not submission timing</li><li>Routing quality matters more than endpoint speed</li><li>Stake-weighted connections determine delivery priority</li><li>Single-path submission breaks under congestion</li><li>Tail latency defines real execution performance</li></ul><h2 id="what-is-solana-transaction-delivery">What Is Solana Transaction Delivery</h2><p>Solana transaction delivery is the process of getting a transaction from submission to the block leader before the slot closes.</p><p>Each slot has a designated leader. If your transaction does not reach that leader in time, it does not land.</p><p>In practice, four things decide that outcome:</p><ul><li>routing path quality</li><li>stake-backed priority</li><li>delivery strategy (single vs multi-path)</li><li>transaction construction</li></ul><p>Priority fees affect ordering once the transaction arrives. Compute limits and blockhash freshness affect inclusion.</p><p>But none of that matters if the transaction never makes it to the leader.</p><h2 id="why-transactions-with-the-same-timing-have-different-outcomes">Why Transactions with the Same Timing Have Different Outcomes</h2><p>Two transactions sent at the same time do not take the same path.</p><p>One may move through prioritized connections with stable bandwidth. Another may compete through shared infrastructure alongside thousands of other transactions.</p><p>Under low load, the difference is small.</p><p>Under congestion, it becomes decisive.</p><p>On Solana, a few milliseconds is not a rounding error. It is the difference between landing in the current slot or missing it entirely.</p><h2 id="what-happens-between-submission-and-the-leader">What Happens Between Submission and the Leader</h2><p>Once submitted, a transaction is forwarded to current and upcoming leaders via QUIC.</p><p>From there, everything depends on:</p><ul><li>connection quality</li><li>routing efficiency</li><li>available bandwidth</li></ul><p>With approximately 390ms slot times, the margin for error is minimal.</p><p>Most variance does not come from when a transaction is sent. It comes from how it is forwarded under load.</p><h2 id="where-public-rpc-falls-short">Where Public RPC Falls Short</h2><p>Public RPC is built for accessibility, not for winning under load.</p><p>That tradeoff shows up in three ways:</p><ul><li>shared bandwidth with no prioritization</li><li>limited control over routing paths</li><li>high variability during peak demand</li></ul><p>Average performance may look fine. But under real conditions, consistency breaks down, and consistency is what execution depends on.</p><h2 id="the-role-of-stake-weighted-qos-in-delivery">The Role of Stake-Weighted QoS in Delivery</h2><p>Stake-weighted QoS operates at the network layer.</p><p>Leaders allocate a significant share of bandwidth to staked connections. Transactions using those connections are less likely to be delayed during congestion.</p><p>This happens before fees come into play.</p><p>Fees decide ordering. Routing decides whether your transaction even gets a chance to be ordered.</p><h2 id="why-connectivity-and-network-positioning-matter">Why Connectivity and Network Positioning Matter</h2><p>With approximately 390ms slots, distance is measured in milliseconds, not in geography.</p><p>What matters is:</p><ul><li>how many hops your transaction takes</li><li>how strong those connections are</li><li>how directly you can reach the leader</li></ul><p>Because the leader rotates continuously, performance depends on consistent access across the validator set, not proximity to a single location.</p><h2 id="why-single-path-delivery-breaks-under-load">Why Single-Path Delivery Breaks Under Load</h2><p>Single-path delivery relies on one route working.</p><p>Under peak demand, that assumption breaks.</p><p>If that path is congested or delayed, there is no fallback already in motion. By the time you retry, the slot is gone.</p><p>This is where tail latency matters.
