Practical tip for crypto checkout: never trust the amount from the frontend.
On 2Settle I re-derive the expected value server side and confirm on-chain before releasing anything. That means verifying the transaction hash, checking confirmations per chain (BTC waits longer than Tron), and matching the amount to the invoice down to the smallest unit.
Skip this and you ship a free-money bug that refunds will not fix. It costs about a day to build and saves you weeks of chargeback chaos.
Building a crypto or Stripe checkout and want a second set of eyes? Message me.
