Struct ClientFeeParams 

pub struct ClientFeeParams { /* private fields */ }

Client fee configuration for the Tycho Router.

When attached to EncodingOptions via EncodingOptions::with_client_fee, the router charges a client fee on the swap output. The signature must be an EIP-712 signature by the receiver over the ClientFee typed data — compute the hash with ClientFeeParams::eip712_signing_hash.

Implementations

impl ClientFeeParams

pub fn new( bps: u16, receiver: Bytes, max_contribution: BigUint, deadline: u64, ) -> Self

Create client fee params.

signature must be a 65-byte EIP-712 signature by receiver.

pub fn with_signature(self, signature: Bytes) -> Self

Set the EIP-712 signature.

pub fn eip712_signing_hash( &self, chain_id: u64, router_address: &Bytes, amount_in: &BigUint, token_in: &Bytes, token_out: &Bytes, min_amount_out: &BigUint, receiver: &Bytes, swaps_hash: &[u8; 32], ) -> Result<[u8; 32], FyndError>

Compute the EIP-712 signing hash for the client fee params.

Pass the returned hash to the fee receiver’s signer, then supply the 65-byte result to ClientFeeParams::with_signature.

The hash covers all 10 ClientFee fields. The swap-specific inputs (amount_in, token_in, token_out, min_amount_out, receiver, swaps_hash) come from a prior unsigned quote request — see FeeBreakdown and the swap_client_fee example for the two-step flow.

• router_address: 20-byte address of the TychoRouter contract.
• amount_in: exact input amount from the order.
• token_in: 20-byte input token address.
• token_out: 20-byte output token address.
• min_amount_out: minimum output after fees — use FeeBreakdown::min_amount_received.
• receiver: 20-byte address receiving the swap output.
• swaps_hash: keccak256 of the encoded swaps bytes — use FeeBreakdown::swaps_hash.
