According to @peterhch, Airwallex has blocked his accounts again, with multi-day response times and repeated flags allegedly due to his company operating in Web3 (source: @peterhch on X, Sep 4, 2025). According to @peterhch, this comes despite a stated shift by Airwallex to embrace crypto after its founder previously criticized stablecoins (source: @peterhch on X). According to @peterhch, traders and Web3 operators relying on Airwallex should account for three immediate risks: unexpected payment freezes disrupting fiat settlement, delayed treasury/vendor transfers due to slow support responses, and on/off-ramp concentration risk during market volatility (source: @peterhch on X). Based on @peterhch’s report, a practical mitigation is to diversify payment rails and maintain stablecoin or fiat buffers to avoid forced de-risking if accounts are frozen (source: @peterhch on X). No company response was included in the post, according to @peterhch (source: @peterhch on X).

According to @kwok_phil, businesses will adopt a stablecoin-first payments approach, then expand to their preferred cryptocurrencies, and ultimately list prices in crypto rather than fiat, source: @kwok_phil. For traders, this scenario signals potential growth in crypto-denominated pricing and settlement that could shift liquidity and quoting toward crypto units on exchanges if the trend materializes, source: @kwok_phil. Monitor announcements of stablecoin acceptance and visible price displays in crypto by large platforms as leading indicators of this path, source: @kwok_phil.

According to @kwok_phil, a major crypto inflection will occur when everyday shops accept crypto at checkout, with adoption accelerating rapidly once merchants turn it on, which is a view aimed at retail payment rails and market readiness (source: @kwok_phil). Traders should note the rails already in production: Stripe supports USDC payments on Solana for merchants, enabling low-fee, fast settlement for retail checkouts (source: Stripe), Shopify merchants can accept BTC and ETH through Coinbase Commerce and BitPay apps in the Shopify ecosystem (source: Shopify; source: Coinbase Commerce; source: BitPay), and Visa has expanded USDC settlement on Solana with merchant acquirers to streamline fiat-crypto settlement flows (source: Visa). These integrations currently channel merchant flows toward USDC on Solana, BTC via Lightning providers, and ETH via on-chain commerce gateways, defining the assets and networks most exposed to retail payment volumes right now (source: Stripe; source: Lightspark; source: Coinbase Commerce; source: BitPay). For positioning, monitor new merchant-integration announcements from Stripe and Shopify, Visa updates on stablecoin settlement, and USDC circulation changes reported by Circle, as these events can shift liquidity and fee dynamics across BTC, ETH, and Solana markets without relying on speculative narratives (source: Stripe; source: Shopify; source: Visa; source: Circle).

For trading, centralization of rails can affect liquidity access, routing, and fee dynamics across crypto payment venues and on-chain markets, making issuer and network design a material factor to watch (source: Lightspark on X).
