Solana Market Updates (Feb 2026)

Recent changes to Solana betting markets and keeper bot configuration.

​
WSOL as Default Market Token

​
Change (Commit 34255ee)

Markets now use the native token (WSOL - Wrapped SOL) instead of GOLD by default. Before: 
const GOLD_MINT = "DK9nBUMfdu4XprPRWeh8f6KnQiGWD8Z4xz3yzs9gpump";
After: 
const MARKET_MINT = process.env.MARKET_MINT || "So11111111111111111111111111111111111111112"; // WSOL

​
Rationale

  • Native Token: WSOL is the native token on Solana (wrapped SOL)
  • Better Liquidity: More liquidity than custom tokens
  • Lower Fees: No token swap fees
  • Cross-Chain: Each chain uses its native token by default

​
Configuration

Override the default market token: 
# Use GOLD instead of WSOL
MARKET_MINT=DK9nBUMfdu4XprPRWeh8f6KnQiGWD8Z4xz3yzs9gpump

​
Migration

Existing markets using GOLD will continue to work. New markets will use WSOL unless MARKET_MINT is explicitly set.

​
Perps Oracle Disabled

​
Change (Commit 34255ee)

Perps oracle updates are now disabled by default. Reason: The perps program is not deployed on devnet, causing oracle update failures. Configuration: 
# Enable perps oracle (only if program is deployed)
ENABLE_PERPS_ORACLE=true

​
Impact

  • Devnet: No impact (program not deployed)
  • Mainnet: Re-enable when perps program is deployed
  • Local: No impact (program not deployed)
// packages/gold-betting-demo/keeper/src/service.ts
const ENABLE_PERPS_ORACLE = process.env.ENABLE_PERPS_ORACLE === 'true';

if (ENABLE_PERPS_ORACLE) {
  // Update perps oracle
} else {
  // Skip perps oracle updates
}

​
Environment Variables

​
New Variables

# Market token mint (defaults to WSOL)
MARKET_MINT=So11111111111111111111111111111111111111112

# Enable perps oracle updates (defaults to false)
ENABLE_PERPS_ORACLE=false

​
Deprecated Variables

# Replaced by MARKET_MINT
# GOLD_MINT=DK9nBUMfdu4XprPRWeh8f6KnQiGWD8Z4xz3yzs9gpump

​
Keeper Bot Configuration

​
Solana Keypairs

The keeper bot uses three keypairs for different operations:
  1. Authority: Initializes config/oracle/market, resolves payouts
  2. Reporter: Reports duel outcomes
  3. Keeper: Locks/resolves/claims-for
Simplified Configuration: 
# Set all three keypairs at once (base58 private key)
SOLANA_DEPLOYER_PRIVATE_KEY=your-base58-private-key
Individual Configuration: 
# Or set individually
SOLANA_ARENA_AUTHORITY_SECRET=authority-private-key
SOLANA_ARENA_REPORTER_SECRET=reporter-private-key
SOLANA_ARENA_KEEPER_SECRET=keeper-private-key

​
Market Maker

The market maker seeds initial liquidity: 
# Market maker keypair
SOLANA_MM_PRIVATE_KEY=mm-private-key

# Wallet address for seeding
DUEL_KEEPER_WALLET=your-solana-wallet-address

​
Testing

​
Local Testing

# Start local Solana validator
solana-test-validator

# Run keeper bot
cd packages/gold-betting-demo/keeper
bun run src/service.ts

​
Devnet Testing

# Configure for devnet
SOLANA_RPC_URL=https://api.devnet.solana.com
SOLANA_WS_URL=wss://api.devnet.solana.com

# Run keeper bot
bun run src/service.ts

​
Migration Checklist

If you’re upgrading from GOLD to WSOL markets:
  • Update MARKET_MINT to WSOL address
  • Update market maker to use WSOL
  • Update betting UI to display SOL instead of GOLD
  • Update price feeds (if using Jupiter/Birdeye)
  • Test on devnet before mainnet deployment
