What's 0slot?

Welcome to 0slot

The Premium Solana Transaction Acceleration Service. Built by traders, for traders.

As active Solana traders ourselves, we've personally felt the frustration of transaction delays and execution failures. Our team doesn't just understand Solana transactions - we operate several of the top-performing arbitrage bots on the network.

This hands-on expertise means we've mastered the art and science of transaction execution, optimization, and timing. We built 0slot after experiencing these pain points firsthand – not just to solve our own challenges, but to empower the entire trading community with the same advantages we developed for our own operations.

We leverage this specialized knowledge to ensure your trades land with exceptional speed and reliability. Let us handle the technical complexities of transaction delivery so you can focus on what matters most - making better trading decisions.

From traders, for traders (从交易者，为交易者) - that's the 0slot promise.

Quickstart

staked_conn

The usage of the staked_conn interface is similar to the RPC interface, primarily providing the sendTransaction method, which directly connects to our validator node.

When calling the sendTransaction method of staked_conn, please note the following:

  • A maximum of 5 calls per second is allowed
  • You need to transfer an amount greater than or equal to 0.0001 SOL to any of the following accounts:

Example for cmd: curl


curl -X POST 'https://ny.0slot.trade?api-key=$TOKEN'
-d '{
    "jsonrpc": "2.0",
    "id": $UUID,
    "method": "sendTransaction",
    "params": [ 
        "<base64_encoded_tx>",
        { "encoding": "base64" }
    ] 
}'

For better performance and faster speeds, you can test and select the most suitable IP to use:

  • NY ny.0slot.trade
  • Frankfurt de.0slot.trade
  • AMS NL ams.0slot.trade
