Initialize wallets for optimal trading speed with Launchpad Trade API
POST/wallets/init
Prepare your wallets for the fastest possible trade execution. Without initialization, the first swap transaction from a wallet will be slower.
Auto-init fallback. If a wallet is not initialized, the first swap through the API will handle it automatically — but with extra latency. For optimal speed from the start, initialize in advance.

​
Quick Start

curl -X POST https://api.launchpad.trade/wallets/init \
  -H "X-API-Key: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "privateKeys": [
      "WALLET_PRIVATE_KEY_1",
      "WALLET_PRIVATE_KEY_2"
    ]
  }'

​
Parameters

ParameterTypeDescription
privateKeysstring[]Array of wallet private keys to initialize. Min 1, max 50. Each wallet must hold at least 0.01 SOL

​
Why Initialize?

The first trading transaction from a new wallet requires additional setup. Initializing in advance removes that overhead so every trade executes at maximum speed — including the first one.
  • One-time cost — ~0.01 SOL per wallet, recovered automatically when no longer used
  • Minimum balance — wallet must hold at least 0.01 SOL
Already-initialized wallets are detected automatically — no extra cost if you call this endpoint again.

​
Region-Specific

Initialization is tied to the region your requests are routed to. If you change server locations and get assigned to a different region, re-initialize your wallets.
  • One-time per region — no need to re-initialize unless you switch locations
  • Idempotent — initializing an already-initialized wallet returns already_initialized at no cost
  • Check your current region with GET /health
If you change your server location or IP address, the load balancer may route you to a different region. Without re-initializing, the first trade from each wallet will have added latency.

Notes

  • Already-initialized wallets return status: "already_initialized" — no duplicate charges
  • A wallet that fails initialization returns status: "failed" with an error field describing the cause
  • The ~0.01 SOL cost is recovered automatically when the wallet is no longer used
  • Initialization is region-specific — check your region with GET /health
