Understanding Cooperative Exits

A cooperative exit involves coordination between your wallet and the SSP to process your withdrawal efficiently. This is the preferred method because:

  • Lower fees than unilateral exits
  • It’s faster
  • No timelocks

​
Initiating the Withdraw

const withdraw_result = await wallet.withdraw({
  onchainAddress:
    "bc1pf8hed85p94emupfpfhq2g0p5c40cgzqs4agvvfmeuy32nxeh549syu2lwf",
  amountSats: 17000,
  exitSpeed: ExitSpeed.MEDIUM
});
console.log("Withdraw Result:", withdraw_result);
The minimum amount to withdrawal is 10,000 sats

​
Withdrawing tokens

You can also withdraw tokens from your spark wallet.

Fee Considerations

  • Network fees are required for the Bitcoin transaction and they will be deducted from the amountSats
  • The total cost will include:
    • Bitcoin network fee
    • Spark service fee (if applicable, charged by the SSP)
    • Example: If you are setting amountSats to 10,000 sats, the bitcoin fees are 2000 sats, and the SSP fees are 1000 sats, you will receive 7000 sats at your L1 address.

​
Best Practices

  • Verify the withdrawal address before confirming
  • Keep track of your exit transaction ID
  • Wait for sufficient confirmations

​
Common Issues

  • Network congestion delays
  • Address format issues
  • Insufficient balance for fees

​
Next Steps

If cooperative exit isn’t possible, you can:
