Infrastructure for crypto payments

Crypto processing, exchangers, OTC desks and P2P operators all need the same plumbing: wallets, key management, blockchain access and reliable deposit detection. This subsection lists crypto infrastructure providers that sell this layer as a service, so a payment company does not have to run its own nodes and signing systems.

Main product types

  • Custody: safekeeping of client and treasury assets, from fully custodial to self-custody tooling.
  • MPC wallets: keys split between parties so no single device holds a full private key; policy engines for approvals.
  • Wallet as a service: API to create deposit addresses per user, track incoming funds and sweep to hot or cold wallets.
  • Node and RPC providers: access to blockchains without running your own infrastructure.
  • Crypto processing API: invoices, payment links, auto-conversion and payouts in USDT and other coins — the base for a crypto payment gateway.

What to check

  • Supported networks and tokens; for stablecoins, TRON and Ethereum coverage plus cheaper L2 options.
  • Security model: MPC or HSM, audits, insurance, incident history.
  • Fees: per address, per transaction, per volume or flat platform fee.
  • Built-in KYT and AML screening of incoming funds.
  • Regulatory status of the vendor and whether you need your own VASP licence.
  • Reliability: confirmations policy, reorg handling, uptime track record.

Where it fits

Infrastructure vendors are technology, not counterparties for exchange. For converting crypto to fiat look at crypto-fiat exchangers, OTC desks and stablecoin settlement; for banking a crypto business, crypto-friendly banks.
