Plain HTTP: POST https://api.voulti.com/invoices with { commerce_id, amount_fiat, reference? } → hosted checkout link. LLM index: voulti.com/llms.txt.

Two payment methods — Connect Wallet or Pay by Address (QR + deposit)
Multi-chain balances — aggregated by token, network auto-selected
Send funds — withdraw to any wallet from dashboard
HD wallet sweep — automatic deposit detection and settlement
Partial/over payment handling — auto-refund on overpay, wait on partial
i18n — Spanish and English

Smart Contracts

Modular proxy architecture deployed on 5 networks:

DerampProxy — entry point, routes calls to modules
DerampStorage — centralized data store
AccessManager — roles, token/commerce whitelisting
InvoiceManager — invoice lifecycle
PaymentProcessor — payment execution, fee calculation
TreasuryManager — service fee collection
WithdrawalManager — commerce fund withdrawals

See contracts/core/deployed-addresses/PRODUCTION.md for all addresses.
