Custodial crypto gateways take 0.5% - 2.56% per invoice, pool balances in shared hot wallets, and freeze payouts behind compliance tickets. CCRails removes custody from the loop: buyers send directly to your address while an edge worker verifies finality and triggers your store webhook.

Settlement engine

On-chain verification built for real buyer behavior

Buyers withdraw from exchanges that skim fees, pick the wrong network, or split transfers. CCRails resolves each case without holding custody.

01

Watch-only public manifests

Your server holds public addresses only. Keys and seeds stay offline in your own vault.

02

Deterministic shard and memo matching

Every invoice locks a unique shard amount or memo tag, so concurrent checkouts never collide.

03

Fee absorption and wrong-asset rescue

Exchange withdrawal deductions, wrong EVM chains, and split transfers still settle automatically.

04

Double-lock webhooks and first-party proxy

One drop-in file, signed webhooks, and optional checkout on your own storefront domain.
