Smart Contracts: Implement Dynamic Fees Based on Network Congestion
Description
The platform currently charges a static fee, which can be unprofitable during periods of high network congestion on the Stellar network. This PR introduces a dynamic fee model that scales the platform fee based on the current ledger's base fee, protecting the protocol's profitability during network spikes while keeping fees reasonable for users.
Changes Made
process_single_paymentinpayment_router/src/lib.rsto calculate a dynamic multiplier based on the current network base fee (env.ledger().base_fee() / 100 stroops). The configuredfee_bpsis multiplied by this dynamic factor.MAX_FEE_MULTIPLIERconstant set to10. The fee multiplier is strictly capped at 10x the normal rate to protect users from exorbitant fees during extreme network congestion events. The absolutefee_capcontinues to enforce an overarching maximum fee limit.get_effective_fee_bpsendpoint with identical multiplier logic, ensuring accurate preflight fee estimations for clients interacting with the contract.Acceptance Criteria
get_effective_fee_bps) are updated to reflect the dynamic fee.How to Test
payment_routercontract on a local network or testnet.get_effective_fee_bpsduring normal conditions (base fee = 100 stroops) to confirm the baseline fee is returned.
