Withdrawal Types

Cypher supports two distinct withdrawal methods to cater to varying privacy and cost preferences:

• Direct Withdrawals: Users engage directly with the pool contract for a streamlined process.

• Relayed Withdrawals: Withdrawals are handled through a relayer to bolster additional privacy layers.

Both approaches rely on zero-knowledge proofs (ZKPs) to verify commitment ownership and uphold user privacy throughout the transaction.Withdrawal Types Comparison

Withdrawal StepsDirect Withdrawal

• Proof Generation The user assembles withdrawal details, generates a zero-knowledge proof (ZKP) to confirm ownership of the commitment, and calculates a new commitment for any remaining balance.

• Contract Interaction The user submits the ZKP to the pool contract, which validates the proof and its context, updates the state (including nullifiers and commitments), and transfers the assets to the designated recipient.

Relayed Withdrawal

• User Steps The user prepares the withdrawal using the Entrypoint contract, creates a zero-knowledge proof (ZKP), and submits it to the relayer off-chain for processing.

• Relayer Steps The relayer conducts a local verification of the proof, submits the transaction to the Entrypoint contract, and covers the associated gas fees.

• Entrypoint Processing The Entrypoint contract verifies the proof and its context, processes the withdrawal through the pool, manages fee distribution, and transfers the assets to the recipient.
