Supreme Power. Self-Hosted Private Stablecoin / Crypto Payments. Zero disruption from day zero • Take charge end-to-end • Rule your freedom

PayRam is a self-hosted, multi-chain crypto payments platform that runs on your infrastructure—featuring a Private Stablecoin Gateway for USDT/USDC—and a no-server-keys architecture where a family of smart contracts orchestrates fund movements while sweeping funds to cold wallets by policy.

• Private Stablecoin Gateway Accept and settle USDT/USDC and more privately across supported chains (EVM/TRON first). Bitcoin also supported.

• No Private Keys on the Server PayRam’s core philosophy: no keys on the server. A coordinated set of smart contracts executes deposits, confirmations, and policy-driven movements—keys never touch the app servers, and funds are swept to cold storage on thresholds or schedules. (Only Gas wallet needs keys for basic ops)

• Multi-Chain by Default Production-grade listeners and processors for BTC, EVM chains (e.g., Ethereum/Base), TRON, TON.

• Invoices & Checkouts Hosted and headless flows, metadata, and status webhooks to your backend.

• Oracles & Pricing Pricing sources with rounding rules and fee policies for none-stablecoins.

• No Account Freezing It's your gateway and your funds. Nobody can stop you.

⚠️ Compliance note: PayRam is infrastructure. You are responsible for KYC/AML/sanctions compliance in your jurisdiction.

Key ideas

• Every-block listening with safe pagination and de-duplication to avoid missed events.
• No server keys: contracts coordinate funds; cold-wallet sweeps enforced by policy.
• Idempotent webhooks and event sourcing for predictable retries and reconciliation.
