Solana market updates

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)

Related Code

// 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
