Acceptance
WalletConnect Pay accepts the token on the specified chain from the buyer as part of the payment flow.Settlement
After acceptance, WalletConnect Pay delivers funds to the merchant or customer in one of the following ways:- Direct Crypto — the payment is settled in crypto to the merchant’s or customer’s wallet. Settlement may involve bridging or swapping before delivery.
- Fiat (USD, EUR) — the accepted token can be converted (offramp) into fiat currency (USD or EUR) via partners, with fiat then delivered to the merchant.
Fiat settlement availability depends on offramp partner support per token and chain. Over time, fiat coverage will expand as WalletConnect Pay introduces internal swaps, allowing a broader set of tokens to be converted into supported offramp assets before payout.
