LaserSell API
Register Wallet
Register a wallet by proving ownership with an Ed25519 signature. Registration is required before connecting wallets to the Exit Intelligence Stream.
No on-chain transaction is needed. Generate the proof locally using your keypair and the SDK’s proveOwnership helper.

}SDK Usage
Generate Proof
Use the SDK’sproveOwnership helper to generate a WalletProof locally. This is a pure cryptographic operation with no network call.
import { proveOwnership } from "@lasersell/lasersell-sdk";
const proof = proveOwnership(keypair);
// proof = { walletPubkey, signature, message }
from lasersell_sdk.exit_api import prove_ownership
proof = prove_ownership(keypair)
# proof = WalletProof(wallet_pubkey, signature, message)
use lasersell_sdk::exit_api::prove_ownership;
let proof = prove_ownership(&keypair);
// proof = WalletProof { wallet_pubkey, signature, message }
proof := lasersell.ProveOwnership(privateKey)
// proof = WalletProof{WalletPubkey, Signature, Message}
Register
Send the proof to the API to register the wallet.const client = ExitApiClient.withApiKey(apiKey);
await client.registerWallet(proof, "My Wallet");
client = ExitApiClient.with_api_key(api_key)
await client.register_wallet(proof, label="My Wallet")
client.register_wallet(&proof, Some("My Wallet")).await?;
client.RegisterWallet(ctx, proof, lasersell.Ptr("My Wallet"))
Connect with Wallets (one step)
Convenience method that registers wallets and connects to the stream in one call.import { StreamClient, proveOwnership } from "@lasersell/lasersell-sdk";
const proof = proveOwnership(keypair);
const client = new StreamClient(apiKey);
const session = await client.connectWithWallets(
[proof],
{ target_profit_pct: 50, stop_loss_pct: 10 },
120, // deadline_timeout_sec
);
from lasersell_sdk.exit_api import prove_ownership
from lasersell_sdk.stream.client import StreamClient
proof = prove_ownership(keypair)
client = StreamClient(api_key)
session = await client.connect_with_wallets(
[proof],
{"target_profit_pct": 50, "stop_loss_pct": 10},
deadline_timeout_sec=120,
)
let proof = prove_ownership(&keypair);
let client = StreamClient::new(api_key);
let session = client.connect_with_wallets(
&[proof],
strategy,
120,
).await?;
// Go SDK: register separately, then connect
proof := lasersell.ProveOwnership(privateKey)
client.RegisterWallet(ctx, proof, nil)
session, _ := stream.ConnectSession(ctx, streamClient, configure)
Authorizations
Your LaserSell API key. Obtain one from the LaserSell dashboard.
Body
application/json
Solana wallet public key to register (base58).
Example:
"9WzDXwBbmkg8ZTbNMqUxvQRAyrZzDsGYdLVL9zYtAWWM"
Ed25519 signature of the message, base58-encoded.
Structured message in the format lasersell-register:<pubkey>:<unix_timestamp>.
The timestamp must be within 5 minutes of the server's current time.
Example:
"lasersell-register:9WzDXwBbmkg8ZTbNMqUxvQRAyrZzDsGYdLVL9zYtAWWM:1706000000"
Optional human-readable label for the wallet.
Example:
"My Trading Wallet"
