  const tx = await program.methods
    .stake(new BN(amount))
    .accounts({
      pool: poolAddress,
      user: wallet.publicKey,
      tokenAccount: userTokenAccount,
    })
    .rpc();
  return tx;
}

// Example: Claim rewards
async function claimRewards(poolAddress: string) {
  const tx = await program.methods
    .claimRewards()

Revenue Model & Economics

Fee Structure

Platform Fees:

Trading fee on pump.fun tokens: 1%
Of this fee: 7% → stakers, 93% → protocol

OPEN Token Fees:

All OPEN token protocol fees: 100% → OPEN stakers

APR Calculation

APR = (Annual Rewards / Total Pool Stake) × 100

Where:
- Annual Rewards = Daily Fees × 365
- Daily Fees = (Trading Volume × Fee %) × Staker Share %

Example Scenario

Pool: BONK Staking Pool Your Stake: 1,000,000 BONK (

100) **Total Pool Stake:** 10,000,000 BONK (

1,000) Daily Trading Fees:

500 **Staker Share:** 7% of fees =

35/day Your Daily Rewards:

= ($35 × 1,000,000 / 10,000,000)
= $3.50/day in SOL

Your APR:

= ($3.50 × 365 / $100) × 100
= 1,277.5% APR

Staking Strategies

High Volume Tokens

Stake in pump.fun tokens with high 24h trading volume for maximum fee generation. Higher volume = more rewards.

OPEN Token Maximalist

Stake all in OPEN token pool for 100% fee share and potential governance rights. Best for long-term believers.

Diversification

Spread stake across multiple pools to reduce risk. If one token’s volume drops, others may compensate.

APR Chasing

Monitor APRs and move stake to highest-yielding pools. Requires active management but maximizes returns.

FAQ

Is there a minimum stake amount?

No, you can stake any amount. However, very small amounts may not be economical due to transaction fees.

Is there a lock-up period?

No lock-up! Stake and unstake anytime. Your rewards accumulate while staked.

How often are rewards distributed?

Rewards accumulate in real-time and can be claimed anytime. No waiting period.

What happens if I unstake?

Unclaimed rewards remain available to claim. No rewards are lost when unstaking.

Can I stake multiple tokens?

Yes! Stake as many different pump.fun tokens and OPEN as you want.

How is APR calculated?

APR is based on trading volume and fees. It’s dynamic and can change daily based on platform activity.
